To set up your email using SSL, set your mail server to the host name for SMTP/POP3/IMAP (instead of domain.com) and then make sure that your mail client is using the following ports for SSL:
- SMTP - 465
- POP3 - 995
- IMAP - 993
Remember to always ensure that your account name is email@example.com (or user+domain.com) and you are using authentication on your SMTP server.
