You can forward incoming email messages with the Postfix
local delivery agent or with Sendmail by
configuring the /etc/aliases file. Entries in
this file can map inbound addresses to local users, files,
commands, and remote addresses.
The following example redirects email for
postmaster to root, and
forwards email sent to admin on the local
system to several other users, including usr04,
who is on a different system:
postmaster: root admin: usr01, usr02, usr03, usr04@another-system.com
To direct email to a file, specify an absolute path name instead
of the destination address. To specify a command, precede it with
a pipe character (|). The next example erases
email sent to nemo by sending it to
/dev/null, and runs a script named
aggregator to process emails sent to
fixme:
nemo: /dev/null fixme: |/usr/local/bin/aggregator
After changing the file, run the command newaliases to rebuild the indexed database file.
For more information, see the aliases(5) manual
page.
