Hello,
I'm seeing a strange email problem with several clients on one of my servers this week.
It seems that some clients are suddenly not able to send email, though they can receive it just fine.
I know what you're thinking...ISP shut off port 25...right???
Nope.
I remoted onto these clients computers, verified they have port 26 entered on advanced tab, pulled up the dos prompt, and successfully used telnet domain.com 26 to log into my mail server. Slides right through like a hot knife through butter. Ports are wide open.
My next thought is that they don't have "My server requires authentication" checked. I check the settings, and they most certainly do.
Next, I remove the account out of their outlook express and re-create the account using correct settings. I close and re-open outlook express, and I still can't send.
Okay, here's where it gets weird... I set up their email account on my own office computer, and I'm able to send just fine.
I checked /etc/apf/deny_hosts.rules for their IP address, and I find nothing.
Anybody got a clue what might be going on?
Thanks in advance for your help.
Larry
