# Pentesting POP3 (ports 110, 995)
## When to Use
- Default ports: `110/tcp` (cleartext POP3) and `995/tcp` (POP3 over TLS / POP3S).
- When `nmap`/banner shows `pop3`, a `+OK ... POP3 server` greeting, or Dovecot/JAMES/Exchange POP3.
- For credential testing and post-auth mailbox retrieval (downloaded mail commonly holds reusable secrets).
## Quick Enumeration
```bash
# Cleartext banner
nc -nv <IP> 110
# POP3S banner
openssl s_client -connect <IP>:995 -crlf -quiet
