My Mailcow (Postfix-based) instance at [login to view URL] has suddenly stopped responding: the admin panel isn’t loading at [login to view URL] and every mailbox login attempt fails. I haven’t altered any server settings prior to this, so I’m looking for someone who can step in immediately, locate the root cause—whether a stalled Docker container, broken certificate, Nginx reverse-proxy rule, or a Postfix/Dovecot glitch—and restore full functionality. Deliverables • Admin UI reachable over HTTPS • Successful authentication to at least one test mailbox via webmail and IMAP/SMTP • Short report outlining the issue and the exact fixes applied (commands, config lines, services restarted) This is an ASAP job; please only respond if you can start right away and work over SSH until everything is back online.

I can step in immediately to diagnose and restore your Mailcow instance so both the admin panel and mailbox logins are fully functional again. My first priority will be to check Docker container status, Nginx reverse-proxy rules, and SSL certificates to identify why the admin UI at port 8443 has stopped responding. From there, I will verify Postfix and Dovecot services, ensuring IMAP/SMTP authentication works correctly and that no stalled containers or misconfigured configs are blocking access. I will work directly over SSH, restarting or rebuilding containers as needed, while preserving your current data and mail flow. Once services are back online, I will test both the admin panel and at least one mailbox via webmail and IMAP/SMTP to confirm stability. You will also receive a short, clear report of the root cause, along with the exact commands and configuration changes applied. With strong experience in Mailcow, Postfix/Dovecot, and Dockerized mail systems, I can get your server back online quickly and ensure it remains stable after the fix.
