the guy who set up this mail server for us is no longer around to help with it so I am trying to fix the issue myself.
After a power outage we are no longer able to send mail out. There is a 2wire firewall in here and i set the TCP for the SMTP at 25 and 465 same with the Host Port. The Imap is set 143 and 993 the https is set to TCP 443
We can log on to our accounts but can't send email, recieving email is not a problem our boxes are flooded but we cant reply.
Another problem I am having is the admin link does not work, I am typing https:/mail.ourserver.com:7071/ZimbraAdmin but it is not working keeps going to a 404 error page not found.
The box is an Ubuntu Server (not sure what version)
