Technical requirements and standard ports
To connect your mailbox via POP3, you need your POP server hostname (e.g. pop.yourdomain.com), your full email address, and your mailbox password.
Hostnames, port 995, and SSL/TLS encryption
Secure POP3 runs over port 995 with SSL/TLS encryption. This ensures data and authentication tokens are encrypted in transit.
Using app-specific passwords
If your provider uses two-factor authentication (like Yahoo or Zoho), you must generate an app-specific password in their security settings.
Leaving a copy on the origin server
POP3 for Gmail gives you full control to leave copies intact on your hosting server or clear them if storage is limited.
UIDL duplicate prevention
The bridge tracks unique UIDL message identifiers so that previously imported emails are never duplicated inside Gmail.
