remailer security, sendmail
I just read an interesting post on alt.hackers. Apparently you
can figure out who's sending mail to who by repeatedly running
the command /usr/lib/sendmail -bp. I just tested this out and
it *seems* to work, as does running /usr/ucb/mailq repeatedly.
How's that for an obscure feature?
Does anyone run a remailer on a multi-user machine where sendmail
is used? Is this sendmail feature a problem? If so, how would
one fix it? (write a wrapper for sendmail? but that requires root
access *sigh*) Am I missing something?
