💖 Mail::...Authres(3) — the Mail::MIMEDefang::Authres glow-up 💖

okay bestie, sit down, hydrate, and let me tell you about Mail::...Authres from the Mail::MIMEDefang::Authres Documentation era. this is the manual page, but make it make sense. 🫶

✨ NAME ✨

Mail::MIMEDefang::Authres — it's the Authentication Results interface for MIMEDefang. that's the whole name, that's the whole vibe. 💅

🌸 DESCRIPTION 🌸

so Mail::MIMEDefang::Authres is a module, right? and its entire job — its main character energy purpose — is to add Authentication Results headers from mimedefang-filter.

that's it. that's the module. it shows up, it writes the header, it leaves. iconic behaviour honestly. ✨

🎀 METHODS 🎀

md_authres 🦋

this is the one. the queen. md_authres returns a mail Authentication-Results header value.

the method accepts the following parameters, and yes, we're going through every single one, no skipping, no cap:

  • $email — the email address of the sender. like, who sent it. that one. 💌
  • $relayip — the relay ip address. the ip of the relay. literally what it says. 🌐
  • $serverdomain — the domain name of the server where MIMEDefang is running on. so like, the server's own domain, not somebody else's. 🖥️
  • $helo (optional) — the MTA helo server name. optional, so you can pass it or not, no pressure, your choice bestie. 🌈
  • $bimi_domain (optional) — the From: header domain to use for BIMI lookup. and here's the tea: when this is provided and when DMARC passes at enforcement level, a "bimi=pass" (or a "bimi=fail") result gets appended to the Authentication-Results header. so it's giving conditional. it's giving ✨appended✨.
lowkey important: that bimi=pass / bimi=fail thing only happens when $bimi_domain is provided AND DMARC passes at enforcement level. both. not one. both. 👑

and that's the whole page, fr fr. nothing hidden, nothing skipped, every parameter accounted for. 💯

sign-off time 🌟 — this little masterpiece is from version 3.7.1, dated 2026-07-20, and it lives under the Mail::...Authres(3) banner (yes, the same one from the top, we just folded it in so it didn't have to sit alone up there). mwah. 💋 🎀🦋💖
