Hello, I have one client on my server that is consistently reporting not being able to send/receive mail, or most time he says he can receive but not send.

This is his last reported error (edited domain):

The connection to the server has failed. Account: 'Dave', Server: 'mail.domainname.com', Protocol: SMTP, Port: 25, Secure(SSL): No, Socket Error: 10060, Error Number: 0x800CCC0E

I have checked everything I can think of on my server and everything seems to be working fine. Absolutely no one else is having any problems with email whatsoever.

I am convinced it is something on his end, and have asked him to check his IE settings a dozen times and he swears they are as I tell him to set them.

I know he is obcessed with stopping spam and has more than one spam filter on his home computer, and I am thinking that is the problem, but I don't know where else to tell him to look.

I have even created a test account on his domain and sent him the proof that it is working fine.

Does anyone have any other ideas where I can tell him to look? I am exasperated at this point.

Thanks

Why dont you setup your own pop account to connect to his email account. Test it. If you can connect and retrieve chances are its a config setting on his side. I had to do this recently to prove to one of my users it was not our server.

Thanks. I had already done that. I was convinced it was a configuration on his side. Finally determined that his ISP (Cox Cable) was intermittantly blocking port 25 evidently. Changed him to another port and all is well!
