Betreff: [Exim] exim as relay for latest sendmail bug?
Hi,

the latest sendmail bug can be exploited by sending a message to a
vulnerable system. Using exim as an application level gateway doesn't
help here, since exim will happily relay the message containing the
exploit to a vulnerable internal system.

Has anybody out here done an analysis of the sendmail bug? Is it
possible to configure exim to not relay an exploiting message, but
instead rejecting it? I would be very interested in solutions for both
exim 3 and exim 4.

Greetings
Marc
