POP3 mail connect error 10060

[IMD]

I have a bit of a mindbending email problem. Recently I moved my email server from one server to another (all hosted) and since the move my incoming email for this account has stopped working. I can send, but not receive email.

When I try to connect for inbound I get Connect Error 10060 - a socket error that implies the server is not responding. However from another machine in the same network I can happily telnet to port 110. From my main machine I can also happily telnet to port 25 on that box... just not port 110.

I've checked the registry for any hardcoded references to my domain/port, but there's nothing untoward.

So i'm lost...

• It's not an Outlook issue as telnet has the same problem.
• If I turn off a/v (Avast) and Firewall (Windows) I get the same result
• It cant be DNS because it resolves to the right IP but just won't connect to that port

Has anybody got a clue what else I can do to diagnose or fix?

Just to add insult to injury, I can telnet to port 110 from a VM hosted on my machine

Turned out to be antivirus after all... it was expecting mail from that server on the SSL port (995) and blocked all other traffic.

Seems my incompetence at disabling my antivirus was part of the problem...
