So, I'm having an issue with "Bad Sender Address Syntax" errors. The
errors are from a variety of formatted email address including some
strange ones like <em...@domain.com/wordpress>. At first, I would shrug
my shoulders to them but my customers started whining and they sort of
had a good point. You see, all of the emails in question have already
been processed by their mail provider and their mail host accepted these
emails. The emails were only getting rejected when they got pulled into
our system so it became an issue of "Why can't you handle these emails
if I've already received them?"
Anyway, I looked at the old threads regarding this and I wanted to run
this by you guys before trying it. Basically, I want to accept any
"MAIL FROM" envelope address. The mail servers in question don't send
bounces and are pure mail stores for our users so it actually doesn't
matter if the envelope address is valid or not as it's never used.
Would the below be correct?
/etc/postfix/main.cf:
smtpd_command_filter = pcre:/etc/postfix/sender_filter
/etc/postfix/sender_filter:
/^(MAIL\s+FROM:\s.*)/ OK
What do you guys think?
Michael
