Hi folks,
I'm finally annoyed enough with the volume of accept-and-bounce malware
bounces I get to do something about it. As postmaster and abuse contact
for an increasing number of domains, I'm getting more than my fair share
of this crap.
I found Philip's Exim filter in the archives[1], but I want to issue an
SMTP time reject, which I don't believe can be done with system or user
filters. Envelope sender signatures[2] aren't suitable, because I
don't control all the hosts that generate legitimate mail from sender
addresses in the affected domains.
Has anyone produced a malware bounce filter in Exim ACLs? The task of
translating Philip's filter into ACLs looks... time-consuming. :-)
Ciao,
Sheldon.
