--- title: Mail Delivery with POP3 hide: - toc # Hide Table of Contents for this page --- **We do not recommend using POP. Use IMAP instead.** If you really want to have POP3 running, add 3 lines to the docker-compose.yml : Add the ports 110 and 995, and add environment variable ENABLE_POP : ```yaml mail: ports: - "25:25" - "143:143" - "587:587" - "993:993" - "110:110" - "995:995" environment: - ENABLE_POP3=1 ```
