In the +last case, any format accepted by linkgit:git-format-patch[1] can +be passed to git send-email, as well as options understood by +linkgit:git-format-patch[1]. + +The header of the email is configurable via command-line options. If not +specified on the command line, the user will be prompted with a ReadLine +enabled interface to provide the necessary information. + +There are two formats accepted for patch files: + +1. mbox format files ++ +This is what linkgit:git-format-patch[1] generates. Most headers and MIME +formatting are ignored. + +2. The original format used by Greg Kroah-Hartman's 'send_lots_of_email.pl' + script ++ +This format expects the first line of the file to contain the "Cc:" value +and the "Subject:" of the message as the second line. + + +OPTIONS +------- + +Composing +~~~~~~~~~ + +--annotate:: + Review and edit each patch you're about to send. Default is the value + of `sendemail.annotate`. See the CONFIGURATION section for + `sendemail.multiEdit`. + +--bcc=<address>,...:: + Specify a "Bcc:" value for each email. Default is the value of + `sendemail.bcc`. ++ +This option may be specified multiple times. + +--cc=<address>,...:: + Specify a starting "Cc:" value for each email. + Default is the value of `sendemail.cc`. ++ +This option may be specified multiple times. + +--compose:: + Invoke a text editor (see GIT_EDITOR in linkgit:git-var[1]) + to edit an introductory message for the patch series. ++ +When `--compose` is used, git send-email will use the From, Subject, and +In-Reply-To headers specified in the message. If the body of the message +(what you type after the headers and a blank line) only contains blank +(or Git: prefixed) lines, the summary won't be sent, but From, Subject, +and In-Reply-To headers will be used unless they are removed. ++ +Missing From or In-Reply-To headers will be prompted for. ++ +See the CONFIGURATION section for `sendemail.multiEdit`. + +--from=<address>:: + Specify the sender of the emails. If not specified on the command line, + the value of the `sendemail.from` configuration option is used. If + neither the command-line option nor `sendemail.from` are set, then the + user will be prompted for the value. The default for the prompt will be + the value of GIT_AUTHOR_IDENT, or GIT_COMMITTER_IDENT if that is not + set, as returned by "git var -l". + +--reply-to=<address>:: + Specify the address where replies from recipients should go to. + Use this if replies to messages should go to another address than what + is specified with the --from parameter. + +--in-reply-to=<identifier>:: + Make the first mail (or all the mails with `--no-thread`) appear as a + reply to the given Message-Id, which avoids breaking threads to + provide a new patch series. + The second and subsequent emails will be sent as replies according to + the `--[no-]chain-reply-to` setting. ++ +So for example when `--thread` and `--no-chain-reply-to` are specified, the +second and subsequent patches will be replies to the first one like in the +illustration below where `[PATCH v2 0/3]` is in reply to `[PATCH 0/2]`: ++ + [PATCH 0/2] Here is what I did... + [PATCH 1/2] Clean up and tests + [PATCH 2/2] Implementation + [PATCH v2 0/3] Here is a reroll + [PATCH v2 1/3] Clean up + [PATCH v2 2/3] New tests + [PATCH v2 3/3] Implementation ++ +Only necessary if --compose is also set. If --compose +is not set, this will be prompted for. + +--subject=<string>:: + Specify the initial subject of the email thread. + Only necessary if --compose is also set. If --compose + is not set, this will be prompted for. + +--to=<address>,...:: + Specify the primary recipient of the emails generated. Generally, this + will be the upstream maintainer of the project involved. Default is the + value of the `sendemail.to` configuration value; if that is unspecified, + and --to-cmd is not specified, this will be prompted for. ++ +This option may be specified multiple times. + +--8bit-encoding=<encoding>:: + When encountering a non-ASCII message or subject that does not + declare its encoding, add headers/quoting to indicate it is + encoded in <encoding>. Default is the value of the + 'sendemail.assume8bitEncoding'; if that is unspecified, this + will be prompted for if any non-ASCII files are encountered. ++ +Note that no attempts whatsoever are made to validate the encoding. + +--compose-encoding=<encoding>:: + Specify encoding of compose message. Default is the value of the + 'sendemail.composeencoding'; if that is unspecified, UTF-8 is assumed. + +--transfer-encoding=(7bit|8bit|quoted-printable|base64|auto):: + Specify the transfer encoding to be used to send the message over SMTP. + 7bit will fail upon encountering a non-ASCII message. quoted-printable + can be useful when the repository contains files that contain carriage + returns, but makes the raw patch email file (as saved from a MUA) much + harder to inspect manually. base64 is even more fool proof, but also + even more opaque. auto will use 8bit when possible, and quoted-printable + otherwise. ++ +Default is the value of the `sendemail.transferEncoding` configuration +value; if that is unspecified, default to `auto`. + +--xmailer:: +--no-xmailer:: + Add (or prevent adding) the "X-Mailer:" header. By default, + the header is added, but it can be turned off by setting the + `sendemail.xmailer` configuration variable to `false`. + +Sending +~~~~~~~ + +--envelope-sender=<address>:: + Specify the envelope sender used to send the emails. + This is useful if your default address is not the address that is + subscribed to a list. In order to use the 'From' address, set the + value to "auto". If you use the sendmail binary, you must have + suitable privileges for the -f parameter. Default is the value of the + `sendemail.envelopeSender` configuration variable; if that is + unspecified, choosing the envelope sender is left to your MTA. + +--sendmail-cmd=<command>:: + Specify a command to run to send the email. The command should + be sendmail-like; specifically, it must support the `-i` option. + The command will be executed in the shell if necessary. Default + is the value of `sendemail.sendmailcmd`. If unspecified, and if + --smtp-server is also unspecified, git-send-email will search + for `sendmail` in `/usr/sbin`, `/usr/lib` and $PATH. + +--smtp-encryption=<encryption>:: + Specify in what way encrypting begins for the SMTP connection. + Valid values are 'ssl' and 'tls'. Any other value reverts to plain + (unencrypted) SMTP, which defaults to port 25. + Despite the names, both values will use the same newer version of TLS, + but for historic reasons have these names. 'ssl' refers to "implicit" + encryption (sometimes called SMTPS), that uses port 465 by default. + 'tls' refers to "explicit" encryption (often known as STARTTLS), + that uses port 25 by default. Other ports might be used by the SMTP + server, which are not the default. Commonly found alternative port for + 'tls' and unencrypted is 587. You need to check your provider's + documentation or your server configuration to make sure + for your own case. Default is the value of `sendemail.smtpEncryption`. + +--smtp-domain=<FQDN>:: + Specifies the Fully Qualified Domain Name (FQDN) used in the + HELO/EHLO command to the SMTP server. Some servers require the + FQDN to match your IP address. If not set, git send-email attempts + to determine your FQDN automatically. Default is the value of + `sendemail.smtpDomain`. + +--smtp-auth=<mechanisms>:: + Whitespace-separated list of allowed SMTP-AUTH mechanisms. This setting + forces using only the listed mechanisms. Example: ++ +------ +$ git send-email --smtp-auth="PLAIN LOGIN GSSAPI" ... +------ ++ +If at least one of the specified mechanisms matches the ones advertised by the +SMTP server and if it is supported by the utilized SASL library, the mechanism +is used for authentication. If neither 'sendemail.smtpAuth' nor `--smtp-auth` +is specified, all mechanisms supported by the SASL library can be used. The +special value 'none' maybe specified to completely disable authentication +independently of `--smtp-user` + +--smtp-pass[=<password>]:: + Password for SMTP-AUTH. The argument is optional: If no + argument is specified, then the empty string is used as + the password. Default is the value of `sendemail.smtpPass`, + however `--smtp-pass` always overrides this value. ++ +Furthermore, passwords need not be specified in configuration files +or on the command line. If a username has been specified (with +`--smtp-user` or a `sendemail.smtpUser`), but no password has been +specified (with `--smtp-pass` or `sendemail.smtpPass`), then +a password is obtained using 'git-credential'. + +--no-smtp-auth:: + Disable SMTP authentication. Short hand for `--smtp-auth=none` + +--smtp-server=<host>:: + If set, specifies the outgoing SMTP server to use (e.g. + `smtp.example.com` or a raw IP address). If unspecified, and if + `--sendmail-cmd` is also unspecified, the default is to search + for `sendmail` in `/usr/sbin`, `/usr/lib` and $PATH if such a + program is available, falling back to `localhost` otherwise. ++ +For backward compatibility, this option can also specify a full pathname +of a sendmail-like program instead; the program must support the `-i` +option. This method does not support passing arguments or using plain +command names. For those use cases, consider using `--sendmail-cmd` +instead. + +--smtp-server-port=<port>:: + Specifies a port different from the default port (SMTP + servers typically listen to smtp port 25, but may also listen to + submission port 587, or the common SSL smtp port 465); + symbolic port names (e.g. "submission" instead of 587) + are also accepted. The port can also be set with the + `sendemail.smtpServerPort` configuration variable. + +--smtp-server-option=<option>:: + If set, specifies the outgoing SMTP server option to use. + Default value can be specified by the `sendemail.smtpServerOption` + configuration option. ++ +The --smtp-server-option option must be repeated for each option you want +to pass to the server. Likewise, different lines in the configuration files +must be used for each option. + +--smtp-ssl:: + Legacy alias for '--smtp-encryption ssl'. + +--smtp-ssl-cert-path:: + Path to a store of trusted CA certificates for SMTP SSL/TLS + certificate validation (either a directory that has been processed + by 'c_rehash', or a single file containing one or more PEM format + certificates concatenated together: see verify(1) -CAfile and + -CApath for more information on these). Set it to an empty string + to disable certificate verification. Defaults to the value of the + `sendemail.smtpsslcertpath` configuration variable, if set, or the + backing SSL library's compiled-in default otherwise (which should + be the best choice on most platforms). + +--smtp-user=<user>:: + Username for SMTP-AUTH. Default is the value of `sendemail.smtpUser`; + if a username is not specified (with `--smtp-user` or `sendemail.smtpUser`), + then authentication is not attempted. + +--smtp-debug=0|1:: + Enable (1) or disable (0) debug output. If enabled, SMTP + commands and replies will be printed. Useful to debug TLS + connection and authentication problems. + +--batch-size=<num>:: + Some email servers (e.g. smtp.163.com) limit the number emails to be + sent per session (connection) and this will lead to a failure when + sending many messages. With this option, send-email will disconnect after + sending $<num> messages and wait for a few seconds (see --relogin-delay) + and reconnect, to work around such a limit. You may want to + use some form of credential helper to avoid having to retype + your password every time this happens. Defaults to the + `sendemail.smtpBatchSize` configuration variable. + +--relogin-delay=<int>:: + Waiting $<int> seconds before reconnecting to SMTP server. Used together + with --batch-size option. Defaults to the `sendemail.smtpReloginDelay` + configuration variable. + +Automating +~~~~~~~~~~ + +--no-[to|cc|bcc]:: + Clears any list of "To:", "Cc:", "Bcc:" addresses previously + set via config. + +--no-identity:: + Clears the previously read value of `sendemail.identity` set + via config, if any. + +--to-cmd=<command>:: + Specify a command to execute once per patch file which + should generate patch file specific "To:" entries. + Output of this command must be single email address per line. + Default is the value of 'sendemail.tocmd' configuration value. + +--cc-cmd=<command>:: + Specify a command to execute once per patch file which + should generate patch file specific "Cc:" entries. + Output of this command must be single email address per line. + Default is the value of `sendemail.ccCmd` configuration value. + +--[no-]chain-reply-to:: + If this is set, each email will be sent as a reply to the previous + email sent. If disabled with "--no-chain-reply-to", all emails after + the first will be sent as replies to the first email sent. When using + this, it is recommended that the first file given be an overview of the + entire patch series. Disabled by default, but the `sendemail.chainReplyTo` + configuration variable can be used to enable it. + +--identity=<identity>:: + A configuration identity. When given, causes values in the + 'sendemail.<identity>' subsection to take precedence over + values in the 'sendemail' section. The default identity is + the value of `sendemail.identity`. + +--[no-]signed-off-by-cc:: + If this is set, add emails found in the `Signed-off-by` trailer or Cc: lines to the + cc list. Default is the value of `sendemail.signedoffbycc` configuration + value; if that is unspecified, default to --signed-off-by-cc. + +--[no-]cc-cover:: + If this is set, emails found in Cc: headers in the first patch of + the series (typically the cover letter) are added to the cc list + for each email set. Default is the value of 'sendemail.cccover' + configuration value; if that is unspecified, default to --no-cc-cover. + +--[no-]to-cover:: + If this is set, emails found in To: headers in the first patch of + the series (typically the cover letter) are added to the to list + for each email set. Default is the value of 'sendemail.tocover' + configuration value; if that is unspecified, default to --no-to-cover. + +--suppress-cc=<category>:: + Specify an additional category of recipients to suppress the + auto-cc of: ++ +-- +- 'author' will avoid including the patch author. +- 'self' will avoid including the sender. +- 'cc' will avoid including anyone mentioned in Cc lines in the patch header + except for self (use 'self' for that). +- 'bodycc' will avoid including anyone mentioned in Cc lines in the + patch body (commit message) except for self (use 'self' for that). +- 'sob' will avoid including anyone mentioned in the Signed-off-by trailers except + for self (use 'self' for that). +- 'misc-by' will avoid including anyone mentioned in Acked-by, + Reviewed-by, Tested-by and other "-by" lines in the patch body, + except Signed-off-by (use 'sob' for that). +- 'cccmd' will avoid running the --cc-cmd. +- 'body' is equivalent to 'sob' + 'bodycc' + 'misc-by'. +- 'all' will suppress all auto cc values. +-- ++ +Default is the value of `sendemail.suppresscc` configuration value; if +that is unspecified, default to 'self' if --suppress-from is +specified, as well as 'body' if --no-signed-off-cc is specified. + +--[no-]suppress-from:: + If this is set, do not add the From: address to the cc: list. + Default is the value of `sendemail.suppressFrom` configuration + value; if that is unspecified, default to --no-suppress-from. + +--[no-]thread:: + If this is set, the In-Reply-To and References headers will be + added to each email sent. Whether each mail refers to the + previous email (`deep` threading per 'git format-patch' + wording) or to the first email (`shallow` threading) is + governed by "--[no-]chain-reply-to". ++ +If disabled with "--no-thread", those headers will not be added +(unless specified with --in-reply-to). Default is the value of the +`sendemail.thread` configuration value; if that is unspecified, +default to --thread. ++ +It is up to the user to ensure that no In-Reply-To header already +exists when 'git send-email' is asked to add it (especially note that +'git format-patch' can be configured to do the threading itself). +Failure to do so may not produce the expected result in the +recipient's MUA. + + +Administering +~~~~~~~~~~~~~ + +--confirm=<mode>:: + Confirm just before sending: ++ +-- +- 'always' will always confirm before sending +- 'never' will never confirm before sending +- 'cc' will confirm before sending when send-email has automatically + added addresses from the patch to the Cc list +- 'compose' will confirm before sending the first message when using --compose. +- 'auto' is equivalent to 'cc' + 'compose' +-- ++ +Default is the value of `sendemail.confirm` configuration value; if that +is unspecified, default to 'auto' unless any of the suppress options +have been specified, in which case default to 'compose'. + +--dry-run:: + Do everything except actually send the emails. + +--[no-]format-patch:: + When an argument may be understood either as a reference or as a file name, + choose to understand it as a format-patch argument (`--format-patch`) + or as a file name (`--no-format-patch`). By default, when such a conflict + occurs, git send-email will fail. + +--quiet:: + Make git-send-email less verbose. One line per email should be + all that is output. + +--[no-]validate:: + Perform sanity checks on patches. + Currently, validation means the following: ++ +-- + * Invoke the sendemail-validate hook if present (see linkgit:githooks[5]). + * Warn of patches that contain lines longer than + 998 characters unless a suitable transfer encoding + ('auto', 'base64', or 'quoted-printable') is used; + this is due to SMTP limits as described by + http://www.ietf.org/rfc/rfc5322.txt. +-- ++ +Default is the value of `sendemail.validate`; if this is not set, +default to `--validate`. + +--force:: + Send emails even if safety checks would prevent it. + + +Information +~~~~~~~~~~~ + +--dump-aliases:: + Instead of the normal operation, dump the shorthand alias names from + the configured alias file(s), one per line in alphabetical order. Note, + this only includes the alias name and not its expanded email addresses. + See 'sendemail.aliasesfile' for more information about aliases. + + +CONFIGURATION +------------- + +include::includes/cmd-config-section-all.txt[] + +include::config/sendemail.txt[] + +EXAMPLES +-------- +Use gmail as the smtp server +~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +To use 'git send-email' to send your patches through the GMail SMTP server, +edit ~/.gitconfig to specify your account settings: + +---- +[sendemail] + smtpEncryption = tls + smtpServer = smtp.gmail.com + smtpUser = yourname@gmail.com + smtpServerPort = 587 +---- + +If you have multi-factor authentication set up on your Gmail account, you will +need to generate an app-specific password for use with 'git send-email'.
