My mail server seems to be working when dealing mails in squirrelmail set up on my server. It also works, when i set up a gmail account for using my server as an smtp server for outgoing mails with login name and passport. This action also leaves some loginfo about connection in mail.log.
But, when i try to login to this smtp account (on my postfix server) using client mail programs, like outlook or thunderbird, i can't even set up the account right, and there is no sign of any activity in mail.log. It only applies for sending e-mails, because imap and pop3 works fine for recieving emails.
Any ideas what did i do wrong? Why is there no sign of attampting to use smtp when i use outlook? Why does SMTP works for gmail (and for mail2web.com too), but doesn't work from outlook? Is there any other log files i should check?
