I wrote down the following regular expression, would it work properly?!
if /^[> ]*From:(.*)(cmat\.edu\.uy)/
if /^[> ]*Message-ID/
!/^[> ]*Message-ID:(.*)(cmat\.edu\.uy)/
REJECT Message-ID and From incorrect
endif
endif
My idea is reject mail whose From header seems to have an e-mail from my
domain, but according to the Message-ID header this message could not be
sent from my server.
I'm using body_checks because these "headers" come as part of bounce
messages we're receiving (backscatter).
Thank you.
Answering to myself...
if /pattern/flags
endif Match the input string against the patterns between
if and endif, if and only if the same input string
also matches /pattern/. The if..endif can nest.
Taken from header_checks(5) manual page. So, I will not find an input
string with From and Message-ID header at the same time. :(
Greetings.
