Hi! Whenever I open Thunderbird or try to get/check new messages I get an error message saying "An error occurred with the POP3 mail server" - how can I fix this? I can still send new emails/reply to existing emails but can't get new ones... The other email accounts work fine...

re :error message saying "An error occurred with the POP3 mail server" Is that the entire error message ? What POP server are you talking about? gmail, yahoo. AT&T, virginmedia etc ?

Suggest you post some info telling us the current server settings. In Thunderbird Help > Troubleshooting Information Mail and News Accounts section Copy all the information and paste it into a 'Post a Reply' text box in this question in the forum.

Message says: "An error occurred with the POP3 mail server. Mail server responded:"

The other three email accounts are IMAPs and they work fine...

Still not a verbatim recitation of the error. it is what the server responded that says what the problem is.

This test suggest there may be issues with the domains MX record.

This test indicated the DIFFIE-HELLMAN PARAMETER is weak. I though it had to be 2048, but I just don't have time to look it up. But that change goes back to Thunderbird 38.
