POP3 timeout question

[omarfilip]

One customer says that his (Apple) mail client times out on port 110 when attempting to retrieve mail from my dedicated server via POP3. His other email accounts from other providers are not affected.

When I try to replicate the issue using Apple Mail and a test account under the same domain, etc, I can get mail just fine.

He is able to get to the Webmail site under his domain.

The issue comes and goes...

What are some possible causes for this? Connectivity issues between his location and Atlanta?

That is usually one of two things, both having to do with the firewall.

If they have their email reader set to automatically check email every minute they may want to change that to every 2 minutes, or use IMAP instead of POP3.

OR

They did something wrong and used the wrong username/password more than a few times in a row (in email, or some other area of the site, log cpanel login, or anywhere else they can enter a login on the server) which has resulted in the server firewalling their IP.

Both are temporary blocks, that is why it "comes and goes" as you say.

Thanks, makes sense. He had it at 1 minute.
