Description
I have not received an email about a flight schedule change due to this:
bad syntax: expected "<" (remaining " <no-reply@koreanair.com>")
Now, I know this issue has come up before, but in different ways.
As @mjl- mentioned in https://github.com/mjl-/mox/issues/51#issuecomment-1656138445 the extra space after MAIL FROM: is not permitted in SMTP.
Mox doesn't allow it, as it is normally a sign of spammers with a sloppy SMTP implementation.
However, it appears that airlines, often infamous for their outdated IT infrastructre, also use sloppy SMTP implementations. This is a problem. If I didn't also receive an SMS notifiaction, I would have never known about this schedule change.
I fully understand that Mox wants to only use correct SMTP and prevent as much spam as possible, but I think the implementation needs to be less strict here.
Note: If you want to poke (or blame) the SMTP server in question, it was tc03.koreanair.com or 211.218.145.102.
Edit: Doesn't look like there is an actual SMTP server behind that address.
