If you want to use POP3(S), you have to add the ports 110 and/or 995 (TLS secured) and the environment variable `ENABLE_POP3` to your `compose.yaml`:
```yaml
mailserver:
ports:
- "25:25" # SMTP (explicit TLS => STARTTLS)
- "143:143" # IMAP4 (explicit TLS => STARTTLS)
- "465:465" # ESMTP (implicit TLS)
- "587:587" # ESMTP (explicit TLS => STARTTLS)
- "993:993" # IMAP4 (implicit TLS)
- "110:110" # POP3
- "995:995" # POP3 (with TLS)
environment:
- ENABLE_POP3=1
```
