SonicWall TZ 190, Can not send email
Posted on 2007-11-25
i have this weird problem.
i have to mail serves outside my network. usually i can use both my email on these server to send and receive emails.
recently we added a sonicwall firewall, one of my email still works fine (incoming and outgoing). the other one on the other hand is only getting incoming emails, i cant seem to send emails out.
i can ping the mail server.
telnet on the mail server, on port 25, was fine.
sonicwall firewall has an allow access on port 25.
am i missing something? anything i should check for?
