SquirrelMail on IspConfig: Can't send
I recently installed squirrel mail on my server that is running IspConfig. For some reason I am able to recieve emails but none of the messages I send are ever recieved. Ispconfig is using Postfix and the server is on an Ubuntu distro. I am using sendmail in SquirrelMail and when I run the configtest.php script it says that everything is working fine, but the problem still persisits.
running telnet localhost says 220 domain.com ESMTP Postfix (Ubuntu)
I have a /etc directory but no /etc/hosts directory.
Does anyone have any ideas on how to fix this? Thanks
