So I setup a full email server using postfix. I found this tutorial so that I could allow my server to send outgoing through my smtp.

Here is the problem, everything is connecting now and I can see its connected properly, however it times out while sending the message. I get this message.

Sending of message failed.
The message could not be sent because the connection to SMTP server rooomies.com timed out. Try again or contact your network administrator.
