I've recently upgraded most software on my servers and both Maia and Perl got a hit ;P
Anyways as of a few days ago I keep(kept) getting mails to the admin account with
"
defined(%hash) is deprecated at send-quarantine-digests.pl.orig line 144.
(Maybe you should just omit the defined()?)
"
Found this quite annoying so I fixed the issue and created a patch
:)
