Log onto incoming mail server (POP3): Your server does not support the connection encryption type you have specified. Try changing the encryption method. Contact your mail server administrator or Internet service provider (ISP) for additional assistance.
Never seen this issue.  How is the client configured?  Is it using SSL port 995?  Is the certificate enabled for POP valid?
