Sisima...xError(3pm)

💖 Sisimai::Reason::SyntaxError(3pm) 💖

ok so real talk, this is a page from the User Contributed Perl Documentation and it's all about Sisimai::Reason::SyntaxError, bestie. buckle up 🎀

---

✨ NAME ✨

Sisimai::Reason::SyntaxError — the vibe check for whether a bounce reason is syntaxerror or not. 💅

---

🌸 SYNOPSIS 🌸

use Sisimai::Reason::SyntaxError;
print Sisimai::Reason::SyntaxError->text;   # syntaxerror

literally that's it. two lines. iconic. 👑

---

🦋 DESCRIPTION 🦋

so Sisimai::Reason::SyntaxError is the little class that checks if the bounce reason is syntaxerror or not. and ngl, it's kinda exclusive — it gets called only by the Sisimai::Reason class. no walk-ins, no plus-ones. 🙈

here's the tea: this is the error you get when the destination mail server literally could not recognize the SMTP command that got sent from the sender's MTA. like, it looked at what your server said and went "…what." 💀

Sisimai will set syntaxerror as the reason if the value of replycode begins with 50, stuff like 502, or 503. yep. that's the whole rule.

Action: failed
Status: 5.5.0
Diagnostic-Code: SMTP; 503 Improper sequence of commands

see that 503 Improper sequence of commands? yeah. that's the energy. it's giving "you didn't say the magic words in the right order." 😭

👑 CLASS METHODS 👑

text()

the text() method returns the fixed string syntaxerror. it does not do anything else. it is not complicated. it is not going to surprise you. it is PERFECT and I love it. 🫶

print Sisimai::Reason::SyntaxError->text;  # syntaxerror

---

match(string)

the match() method always returns 0.

no cap, it always returns 0. that's the whole bit. don't overthink it. 💀

---

true(Sisimai::Fact)

the true() method returns 1 if the bounce reason is syntaxerror. 🎉

important detail though, bestie: the argument must be a Sisimai::Fact object, and this method gets called only from the Sisimai::Reason class. so like, don't just roll up with anything. it knows. ✨
