Hello, I'm using ability mail server 1.12. I'm behind a router. All services work perfectly (including receiving mails from outside)but I can't send email to a hotmail account. In log files, it said Mail Transaction Failure. I'm sure I've opened all ports 110,25,8000,143 (for web mail) and dmz.
Thanks a lot!
