Ubuntu 8.10; KDE 3.5; Using Postfix configured by and for ISPconfig with my domain and IP behind router, but all comps with real IP
I have a mail server with the given configuration. I has no problems till recently, when suddenly I stopped receiving mail.
When I try to send mail from my work the server tries to send several times and then claims for "connection timed out".
I tried telnet to port 25 and it worked fine and sent the mail, but unfortunately I only checked it from within my LAN.
If it doesn't work from out side it might be my new router (Edimax), though I don't use NAT and the FW is disabled...
Any other ideas?
