Yacc grammar for parsing RFC 822 style headers?

Dear Readers,


I am looking for yacc (bison) grammar file that can be compiled and then
used to parse 822 style mail addresses and headers. I am attempting to
write a accounting utility that will monitor the mail traffic in and out
of our campus LAN. The utility will generate monthly reports on the email
for various individual or group users. If the yacc grammar file already
exists and is freely available, I could use it to extract pertinent info
from mailer log files (e.g, MMDF) and uucp work files (rmail). Info such
as sender's username, i.e., machine name and domain name stripped,
recipient, recipient's host and domain.


If the grammar file is ftp'able, please point me to the machine and
directory. I'll use ftp-by-mail@decwrl.dec.com to get it.


Please reply to me by email. We don't receive news here.


advan-Thanks-ce
