zmailer subject filtering ? ( ie controlling Melissa virus)
In light of the recent Melissa email Virus, I was wondering
how, in zmailer, to emulate the sendmail patch posted at:
ftp://ftp.cert.org/pub/cert_advisories/Patches/CA-99-04-sendmail-melissa-filter.txt
In this config patch to LOCAL_RULESETS for sendmail, it is
suggested to provide filtering on:
HSubject: $>local_check_header
D{MelissaMessage}"553 Your message may contain the Melissa virus. \
Please email postmaster@$j if you have questions."
Slocal_check_header
RImportant Message From $* $#error $: ${MelissaMessage}
RRe: Important Message From $* $#error $: ${MelissaMessage}
which is a weak kludge, yes (because a similar virus only needs to alter
the subject line), but it may at least serve to control spread of the
current macro virus.
Is there a quick kludge for same in zmailer?
Cheers,
