I already wrote about sending mails with ssmtp<\/a>, a simple alternative to sendmail. But since I got a few questions (and I tend to forget myself) how to use ssmtp’s revaliases<\/code>-file, here is a short reminder:<\/p>\n

\/etc\/revaliases<\/code>, allows you to map a local user to a specific ‘From:’ address on outbound mail<\/strong> and to route that mail through a specific mailhub. But it will not rewrite the ‘To:’ address according to the local user who should receive the mail.<\/p>\n

Usually, you would add aliases to \/etc\/aliases<\/code> to ensure that a local user (receiving a mail) is mapped to a valid eMail address. But as the documentation clearly says (if you actually read it), ssmtp does not use \/etc\/aliases<\/code><\/strong>.<\/p>\n

The solution turns out to be letting mail<\/code> handle the alias \u2013 which is done by configuring aliases in \/etc\/mail.rc<\/code><\/p>\n

\r\nset ask askcc append dot save crt\r\nignore Received Message-Id Resent-Message-Id Status Mail-From Return-Path Via Delivered-To\r\nalias root root<yourname@domain.com>\r\nalias localuser localuser<yourname@domain.com>\r\n<\/pre>\n
You can test it with with:<\/p>\n
\r\n# echo test | mail -s \"testing ssmtp\" localuser\r\n<\/pre>\n
The mail will actually be delivered to yourname@domain.com (since ‘localuser’ is mapped to this address in \/etc\/mail.rc<\/code>).<\/p>\n
Enjoy!<\/p>\n
