Hi list Implementing DRP, and like a bicycle... too tired :-) Fresh install of: FC4 Postfix-2.2.2 Cyrus-IMAP-2.2.12 web-cyradm-0.5.4-1 as per: http://www.campworld.net/thewiki/pmwiki.php/LinuxServers/FC4VirtMailServer The server is stand alone internet server. I can SMTP email from the server via Squirrelmail (on server), but not via an email client (off server).
