Pop 3 connector problem with Exchange on SBS

HI there,

I am kind of new to Exchange. And I am getting this error on my SBS Server since I configured the pop3 connector in exchange.

"A error occurred in connecting to the <pop.xxxxxx.xxx> POP3 server for user <xxxxxxxxx>. The error is 11004. The server may be down for maintenance or your server is not connected to the Internet."

I have 10 mailboxes and they all end with this error in the event log.

HAve any clue of what it is?

Please see this posting from EventID.net:  http://eventid.net/display.asp?eventid=1035&eventno=4109&source=POP3%20Connector&phase=1

It's a mismatched MTU setting.

Hi Jeff,

Not even that. Before coming in here, I've been on Event ID.NET and read this article about the error.

It was late at night, like many IT Tech I was working like BatMan in the dark and... the pop connector contained simply WRONG pop server addresses... After correcting this mistake everything started to run smoothly.

What I really regret is that Event Log from Microsoft should have a better and simplier way to say "hey dude, wrong pop server" instead of that crap...

Anyway, thanks for your quick answer and I give you all points anyway!! :-)

Best Regards.

No problem... FYI, the POP3 connector is something that Microsoft includes to help transition over to SMTP email.  Which is really much better to work with, not to mention that it's real-time instead of the 15-minute delay with the POP3 connector.

Plus, there is a tool (smptdiag.exe) which would pick up stuff like that!  :-)
