[KLUG Members] Parsing bad e-mail

[Adam Bultman]

Greetings, everyone.  I'm writing a perl script that needs to parse
returned email for the address it was originally sent to.

So, I'm trying to write a perl parser that will run through the file, line
by line, and find and write down any email addresses it finds (it will be
coming from one host, obviously).

So far, I've found I can get addresses this way:

/550\s{0,}(\w.*)\.\w.*/  -> Searches for the 550 error

/^To:\s{0,}(\w.*)  -> Searches for the To: stuff, after which I strip out
the sender, and then like, 'postmaster', since I relaly don't care about
that.


Anyway, what exactly are the conventions for this?  I'm not aware of all
the error codes for returned mail, although now that I think of it, I
should search harder than I did.  Is there a catchall for returned mail?
I just need to catch, and write down, all the bad addresses that land in
my box here.

(I searched cpan and perlmonks.org for a mail parser, but I didn't find
something that suited me just right).
