Everything is fine when checking with smtdiag.exe
Everything works fine with telnet.
Tried from outside, connect to mail server everything works fine also - this means no ports are blocked.
The problem is that mail server is unable to recieve any email messages... Tried from yahoo.com, from gmail.com send some test emails but these emails don't arrive to mail server, there is no new messages when checking with telnet "list"...
Emails are just disappearing somewhere... How to check what's wrong?
