If the e-mail program does not support encryption, you can check your mail using only the POP3 protocol, using the following settings:
Incoming mail server (POP3-server): insecure.mail.ee
Port POP3 server: 110
Outgoing Mail Server (SMTP-server): insecure.mail.ee
SMTP server port: 587 (or 25) without SSL/TLS
REMEMBER, there is high risk of hacking your mailbox when unencrypted communications are used!
