When I attempt to send a message from Squirrelmail, I receive the following error: Command parameter not implemented Server replied: 504 5.5.2 <192.168.0.100>: Helo command rejected: need fully-qualified hostname The IP listed above is the IP address of the server that is running Postfix, Dovecot, and Squirrelmail. I don't see anything listed in /var/log that would help me explain what is causing this problem. In Squirrelmail, I am able to login to the web GUI with no problems and also am able to receive messages fine so this maybe an IMAP issue or a Squirrelmail config. Anyone know what I did wrong? I am using v1.4.9a-2. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ ----- squirrelmail-users mailing list Posting guidelines: http://squirrelmail.org/postingguidelines List address: squirrelmail-users@xxxxxxxxxxxxxxxxxxxxx List archives: http://news.gmane.org/gmane.mail.squirrelmail.user List info (subscribe/unsubscribe/change options): https://lists.sourceforge.net/lists/listinfo/squirrelmail-users
