Postfix and UUCP

+ +

Using UUCP over TCP

+ +

Despite a serious lack of sex-appeal, email via UUCP over TCP +is a practical option for sites without permanent Internet connections, +and for sites without a fixed IP address. For first-hand information, +see the following guides:

+ +

Jim Seymour's guide for using UUCP over TCP at +http://jimsun.LinxNet.com/jdp/uucp_over_tcp/index.html, + +
Craig Sanders's guide for SSL-encrypted UUCP over TCP +using stunnel at http://taz.net.au/postfix/uucp/. + +

+ +Here's a graphical description of what this document is about: + +

+ +

Setting up a Postfix Internet to UUCP +gateway

+ +

Here is how to set up a machine that sits on the Internet and +that forwards mail to a LAN that is connected via UUCP. See +the LAN to UUCP gateway section for +the other side of the story.

+ +

You need an rmail program that extracts the sender +address from mail that arrives via UUCP, and that feeds the mail +into the Postfix sendmail command. Most UNIX systems come +with an rmail utility. If you're in a pinch, try the one +bundled with the Postfix source code in the auxiliary/rmail +directory.
+ +
Define a pipe(8) based mail delivery transport for delivery +via UUCP:
+ +
```
+/etc/postfix/master.cf:
+    uucp      unix  -       n       n       -       -       pipe
+      flags=F user=uucp argv=uux -r -n -z -a$sender - $nexthop!rmail ($recipient)
+
```
+ +
This runs the uux command to place outgoing mail into +the UUCP queue after replacing $nexthop by the next-hop hostname +(the receiving UUCP host) and after replacing $recipient by the +recipients. The pipe(8) delivery agent executes the uux +command without assistance from the shell, so there are no problems +with shell meta characters in command-line parameters.
+ +
Specify that mail for example.com, should be +delivered via UUCP, to a host named uucp-host:
+ +
```
+/etc/postfix/transport:
+    example.com     uucp:uucp-host
+    .example.com    uucp:uucp-host
+
```
+ +
See the transport(5) manual page for more details.
+ +
Execute the command "postmap /etc/postfix/transport" +whenever you change the transport file.
+ +
Enable transport table lookups:
+ +
```
+/etc/postfix/main.cf:
+    transport_maps = hash:/etc/postfix/transport
+
```
+ +
Specify dbm instead of hash if your system uses +dbm files instead of db files. To find out what map +types Postfix supports, use the command "postconf -m".
+ +
Add example.com to the list of domains that your site +is willing to relay mail for.
+ +
```
+/etc/postfix/main.cf:
+    relay_domains = example.com ...other relay domains...
+
```
+ +
See the relay_domains configuration parameter description for +details.
+ +
Execute the command "postfix reload" to make the +changes effective.
+ +

+ +

Setting up a Postfix LAN to UUCP +gateway

+ +

Here is how to relay mail from a LAN via UUCP to the +Internet. See the Internet to UUCP +gateway section for the other side of the story.

+ +

You need an rmail program that extracts the sender +address from mail that arrives via UUCP, and that feeds the mail +into the Postfix sendmail command. Most UNIX systems come +with an rmail utility. If you're in a pinch, try the one +bundled with the Postfix source code in the auxiliary/rmail +directory.
+ +
Specify that all remote mail must be sent via the uucp +mail transport to your UUCP gateway host, say, uucp-gateway:
+ +
```
+/etc/postfix/main.cf:
+    relayhost = uucp-gateway
+    default_transport = uucp
+
```
+ +
Postfix 2.0 and later also allows the following more succinct form:
+ +
```
+/etc/postfix/main.cf:
+    default_transport = uucp:uucp-gateway
+
```
+ +
Define a pipe(8) based message delivery transport for mail +delivery via UUCP:
+ +
```
+/etc/postfix/master.cf:
+    uucp      unix  -       n       n       -       -       pipe
+      flags=F user=uucp argv=uux -r -n -z -a$sender - $nexthop!rmail ($recipient)
+
```
+ +
This runs the uux command to place outgoing mail into +the UUCP queue. It substitutes the next-hop hostname (uucp-gateway, +or whatever you specified) and the recipients before executing the +command. The uux command is executed without assistance +from the shell, so there are no problems with shell meta characters. +
+ +
Execute the command "postfix reload" to make the +changes effective.
