My Web Host (APLUS.NET) Doesn't Work Well With Mail. Need Suggestions.

Hey guys,

I've been with Aplus.net for 5 years or so now. I've been having lot's of problems with my email portion of my service with them. Aplus.net claims that the problems are all related to Apple Mail, as there is known history of problems with the mail client interacting with their servers. They recommend we use Thunderbird or other 3rd party mail clients. But we want to use mail. What Web Hosts do you use with Apple Mail that is dependable? We highly depend on our email for our work and need it to work.

FYI, issues we encounter are related to constant clocking with errors;
- Mail can’t verify the identity of “pro33.abac.com”.
- An SSL error has occurred and a secure connection to the server cannot be made.
- There may be a problem with the mail server or network. Check the settings for account XXXXX” or try again.
- The server error encountered was: The connection to the server “pro33.abac.com” on port 993 timed out.

All settings are correct and errors are sporadic. Some accounts connect, some don't. Some computers connect with account "A" while the computer right next to it with the same account won't connect.

Thanks for your input!
