Mail Server Setup & Deliverability
Self-hosted mail with Exim4, Mailcow, Postfix, and Dovecot — configured with SPF, DKIM, and DMARC so mail actually reaches the inbox.
Running your own mail server is straightforward to get sending — and surprisingly easy to get landing in spam folders. I set up self-hosted mail with Postfix and Dovecot, Exim4, or Mailcow as a full all-in-one stack, and configure the DNS side (SPF, DKIM, DMARC, and reverse DNS) that mail providers actually check.
Beyond the initial setup, that includes spam filtering with Rspamd or SpamAssassin, webmail access, and IMAP/SMTP configuration for desktop and mobile clients.
If you already have mailboxes somewhere else, they can be migrated to the new server without losing messages — and if deliverability is the actual problem on an existing server, that's something I can diagnose and fix directly.
