Postfix & Dovecot

Postfix and Dovecot are the industry-standard combination for self-hosted email. Postfix handles sending and receiving mail (SMTP), while Dovecot provides mailbox access (IMAP/POP3). Together, they power millions of mail servers worldwide, including many of the largest email providers.

Why self-hosted email

When your email runs on Microsoft 365 or Google Workspace, every message passes through infrastructure you do not control, in jurisdictions you may not trust. Self-hosted email with Postfix and Dovecot means your communication stays on your servers, under your rules. No third party scans your messages, and no foreign government can compel access without your knowledge.

Production-grade reliability

Postfix is known for its security, performance, and clean design. Dovecot handles millions of mailboxes efficiently and supports modern features like full-text search, quotas, and shared folders. Together, they provide everything a company needs for professional email: spam filtering, DKIM, SPF, DMARC, TLS encryption, and more.
