+
+By default Linux /etc/hosts lookups do not support multiple IP address per
+hostname. This causes warnings from the Postfix SMTP server that "hostname XXX
+does not resolve to address YYY", and is especially a problem with hosts that
+have both IPv4 and IPv6 addresses. To fix, turn on support for multiple IP
+addresses:
+
+    /etc/host.conf:
+        ...
+        # We have machines with multiple IP addresses.
+        multi on
+        ...
+
+Alternatively, specify the RESOLV_MULTI environment variable in main.cf:
+
+    /etc/postfix/main.cf:
+        import_environment = MAIL_CONFIG MAIL_DEBUG MAIL_LOGTAG TZ XAUTHORITY
+    DISPLAY LANG=C RESOLV_MULTI=on

+
+If you can't compile Postfix because the file "db.h" isn't found, then you MUST
+install the Berkeley DB development package (name: db???-devel-???) that
+matches your system library. You can find out what is installed with the rpm
+command. For example:
+
+    $ rrppmm --qqff //uussrr//lliibb//lliibbddbb..ssoo
+    db4-4.3.29-2
+
+This means that you need to install db4-devel-4.3.29-2 (on some systems,
+specify "rrppmm --qqff //lliibb//lliibbddbb..ssoo" instead).
+
+DO NOT download some Berkeley DB version from the network. Every Postfix
+program will dump core when it is built with a different Berkeley DB version
+than the version that is used by the system library routines. See the DB_README
+file for further information.

+PPrrooccmmaaiill iissssuueess
+
+On RedHat Linux 7.1 and later pprrooccmmaaiill no longer has permission to write the
+mail spool directory. Workaround:
+
+    # chmod 1777 /var/spool/mail
+
+SSyyssllooggdd ppeerrffoorrmmaannccee
+
+LINUX ssyyssllooggdd uses synchronous writes by default. Because of this, ssyyssllooggdd can
+actually use more system resources than Postfix. To avoid such badness, disable
+synchronous mail logfile writes by editing /etc/syslog.conf and by prepending a
+- to the logfile name:
+
+    /etc/syslog.conf:
+        mail.*                          -/var/log/mail.log
+
+Send a "kkiillll --HHUUPP" to the ssyyssllooggdd to make the change effective.
