Don't put the filename in double-quotes. The correct setting is: mydestination = $mydomain, $myhostname, localhost.$mydomain, localhost, /etc/postifx/local-host-names You could also arrange for some minimal address rewriting on the various hosts, so that mail to u...@somehost.example.com is rewritten to u...@example.com. Perhaps by adding "example.com" to "masquerade_domains". See also: http://www.postfix.org/postconf.5.html#local_header_rewrite_clients -- Viktor.
