The most likely issue with the server port settings is that the incoming mail port should be set to 110.
Key Takeaway: POP3 uses port 110, and therefore if using that protocol, the port needs to be set correctly. Port 143 is the port for IMAP connections. Although port 25 is a correct port for SMTP, many newer servers are using an SMTP relay through submission port 587, which provides more outbound mail security (and backup-since you are sending through the remote server).
