Hello, This is my first time attempting to configure a mail server. For the purposes of this thread, let my domain name be abc.com. I followed the instructions at http://www.exratione.com/2012/05/a-mailserver-on-ubuntu-1204-postfix-dovecot-mysql/. Outgoing mail seems to be working; the problem is with incoming mail. The message on the server says: postfix/smtpd[2642]: NOQUEUE: reject_warning: RCPT from abc: 504 5.5.2 <phil>: Helo command rejected: need fully-qualified hostname; from=<[email protected]> to=<[email protected]> proto=SMTP helo=<phil> In this case, abc.com is an existing domain name that does not currently point to this server. I wish to configure this server fully before changing the DNS so as to minimize downtime. Furthermore, "phil" is the name of the local computer I am using to connect to the mail server. It seems unreasonable to me for the server to expect that every client machine has a fully qualified domain name. Therefore, I suspect that something is wrong with the configuration settings specified in the tutorial I followed. Any help in this matter would be greatly appreciated. Version information: /etc/postfix/main.cf:
I did have a fully-qualified hostname in /etc/hostname, but I scrapped that installation and went with the one at http://www.howtoforge.com/virtual-u...urier-mysql-and-squirrelmail-ubuntu-12.04-lts instead. It's up and running, but I'm having some performance problems, for which I've started a thread at http://www.howtoforge.com/forums/showthread.php?p=283666#post283666. Thanks!
