Subject: RE: Timeouts with SMTP for users

Any chance the SMTP svc is dying periodically then restarting automagically? Perhaps look at Imail's running instance of WUG logging to verify that the WUG module is monitoring the svc and that is either not going down or if it is going down if it is getting restarted by WUG automatically. I usually use an external instance of WUG to check these types of oddities because I have come to not trust the internal WUG engine.

Thanks Scott, but these are local users dialing into our network directory - not users coming in from remote POPs (like MegaPop). I agree that it sounds like port 25 being blocked, but we're not blocking it on our network (this has been reconfirmed). Sometimes the user rebooting fixes the problem temporarily - which would point to client side issues. But, it seems to be happening more and more lately so we're forced to investigate server issues also.

Then port 25 blocking on the remote ISP is almost certainly the problem. If they get a timeout telneting to port 25, but not port 110, it's almost certainly port 25 blocking. If they can't get to port 25 (and can get to port 110), and you can get to port 25 locally, you can be sure that the remote ISP is blocking access to port 25.
