# Strongthium Mail Discussions

Strongthium Mail receives, checks and sends your domains' mail and keeps it on your own server, on Linux or Windows. Every message or connection it turns away is logged with a reason code, what the server found and where it came from, so "why didn't their mail arrive?" has an answer. It checks its own setup (DNS names, reverse DNS, the certificate, each domain's MX, SPF, DKIM and DMARC, blocklists), marks each OK or Problem, and offers a button to put it right. It writes your MX, SPF, DKIM, DMARC, MTA-STS and TLSA records for each domain, then asks DNS whether each is there. Junk is caught by named verdicts such as extortion, phishing or a fake invoice, each giving its reasons, and each starts in a watch mode so you see what it would catch first. Addresses that keep getting refused ban themselves for a day, mail that claims your domain must come from your server, and DMARC, TLS and complaint reports are turned into pages you can read. Many domains and alias domains, mailboxes with quotas, groups, forwarding, catch-alls you can steer, TLS on every port, a certificate in one command, sign-in limited to the places you say, relaying through a smart host, and administrator roles. Everything is in its web interface, and nearly all of it on its command line. It comes with Angaros, a desktop mail client for Windows with a calendar and meetings, included on the free license too. An MSP edition gives hosting customers their own logins, packages and sending limits. Free for one domain with no time limit; paid licenses by domain.
