# Mail Delivery with POP3

Warning

We do not recommend using POP3. Use IMAP instead.

If you really want to have POP3 running add the ports 110 and 995 and the environment variable `ENABLE_POP3` to your `docker-compose.yml`:

    mail:
      ports:
        - "25:25"
        - "143:143"
        - "587:587"
        - "993:993"
        - "110:110"
        - "995:995"
      environment:
        - ENABLE_POP3=1
