Have postfix running on Fedora 8 with ISPConfig... able to receive mail, but, not send it out. Can send locally, however. When trying to send externally I get "Connection timed out (port 25)" error in the log. I haven't been able to find much about this error anywhere... any ideas? Also, when trying to send from Outlook mail client, I get a 554 5.7.1: Relay access denied... when sending from local webmail client, it says it sends fine, but, it gets deferred after a "Connection timed out" error in the log. main.cf file is setup exactly like the "Perfect Server" setup for Fedora 8 & local-host-names are correct. thanks!
