Mail::...iteral(3pm)

💅 Mail::Milter::Module::HeloRawLiteral — yes that's the whole vibe

okay bestie, so this little page you're reading is Mail::...iteral(3pm) from the User Contributed Perl Documentation corner of the world (the name got cut off mid-glow-up, tragic, but we move). Underneath the truncation it's the manpage for Mail::Milter::Module::HeloRawLiteral, and ngl it's a tiny little icon doing one very specific job. Let's get into it. 🎀

✨ NAME ✨

Mail::Milter::Module::HeloRawLiteral — it's a milter that checks for an IP literal without brackets in HELO. That's it. That's the whole personality. One job, done flawlessly. 💅

---

🦋 SYNOPSIS 🦋

the group chat version of "how do I even use this":

use Mail::Milter::Module::HeloRawLiteral;

my $milter = new Mail::Milter::Module::HeloRawLiteral();

my $milter2 = &HeloRawLiteral; # convenience

so yeah — you use it, you new it up, and if you're feeling lazy (affectionate) there's a &HeloRawLiteral shortcut that does the same thing with way less typing. convenience queen behavior fr fr. 👑

🌸 DESCRIPTION 🌸

okay so here's the tea. RFC2821:4.1.3 says you are allowed to use a raw IP address in HELO… but only if it's wrapped in [square brackets]. that's the rule, that's the law, that's the assignment.

and the way spam engines just… forget the brackets? not them being sloppy with the dress code 😭 so this milter's entire main character arc is catching exactly that. raw IP in HELO, no brackets? caught. slay. ✨
