Hi,
Recently, a remote DoS vulnerability was discovered in postgrey, the
greylisting daemon for the postfix MTA. postgrey's author, David
Schweikert, immediately fixed the problem in postgrey 1.21, and a fixed
Debian package is available in unstable right now and will propagate to
sarge very quickly.
All postgrey users should immediately upgrade their systems to postgrey
1.21.
greetings
Adrian von Bidder
postgrey Debian package maintainer
