SMTP syntax errors #9

Closed DerDakon closed 7 years ago

It's "MAIL FROM:<…>" and "RCPT TO:<…>", i.e. no spaces between colon and opening brace, see RfC 5321.

Thanks for the report, you're indeed correct. Out of interest - what SMTP server rejects the space? I haven't had any other reports about that...

Qsmtp has a per-user setting to reject those as they are often a sign of spam bots.
