Mail check

I am a Pandora newbie and I do not seem to be able to check mail here is the message I get:
Task: Checking
Status: Not Completed
Details: TLS/SSL connection error: A failure in TLS/SSL library occurred. Try again later.
Completed: 4 %
Time: 4/14/2018 12:55:58 PM

I am a long time Eudora user (7.1.0.9)

Hello Jack and welcome to Pandora forum.

Can you tell us something more about your current settings for that account:
Type (POP or IMAP), SSL and Port #.

What is the name of your ISP/domain? (verizon, aol, gmail)

Server is Centurytel.net. It is a pop type of account. Another problem is that when I have a successful fetch of mail I get 4 or even 5 (sometimes) copies of the exact same message. Makes for a lot of deletions. Port is 587. In Eudora I have "Secure Sockets when receiving set as Never.

587 is usually used for outbound. You should always have successful fetch (and no duplicates). Here are correct specs:
Server: pop.centurytel.net
Secure Sockets: Always
Port: 995

Thank you. I will give it my best shot!
