Hi MailScanners. Last night, after (i think so) a Perl upgrade to
perl-5.8.6-18 (Fedora Core 4, selinux disabled) MailScanner stoped
working. The setup is MailScanner+Postfix+SpamAssassin+Pyzor. For the
moment SpamAssassin+Pyzor are not active.
When I saw the problem I've upgraded MailScanner to 4.48.4-2(rpm) but no
change.
The mail makes it's way to the hold directory, and when it comes to
MailScanner (Debug=yes):

Can't call method "DropFromBatch" on unblessed reference at
/usr/lib/MailScanner/MailScanner/Postfix.pm

This is the one and only debug line and the proces dies. When
SpamAssassin is enabled there is much more output, but everything before
this line looks perfect.

Any ideas/help?
