| Intended users | The documentation suggests hMailServer for small businesses, developers needing an SMTP and IMAP test endpoint, and hosting providers. | The project describes postfix-users as a forum for people using Postfix and postfix-devel as a list for those designing, implementing, or maintaining its source code. |
| Mail protocols | It serves mail to clients such as Outlook, Thunderbird and Apple Mail, or through its built-in webmail. | Postfix supports SMTP and LMTP features including SASL authentication, TLS, IPv6, and SMTPUTF8. |
| Purpose | hMailServer is a self-hosted mail server that supports SMTP, IMAP and POP3. | Postfix aims to be fast, easy to administer, and secure. |
| Support | Free help is available on the community forum, where answers are not gated behind a support plan. | The postfix-users mailing list is for questions, problem reports, and feature requests; non-member postings are silently discarded. |
