I have successfully set up my email server and would like to configure it with external mail clients such as Microsoft Outlook and Gmail.

Could you please provide the recommended server settings for both IMAP and POP3? Specifically, I would appreciate the following details: Incoming server hostname and port
Outgoing (SMTP) server hostname and port
Required security/encryption type (SSL/TLS, STARTTLS, etc.)

Your feedback is much appreciated.
