Emails get stuck in the incoming queue (mqueue.in)

[Stefan Rapp]

We have also a problem with our installation over here. We see stuck
mails in mqueue.in that are processed over and over again. The only
solution is to move them away by hand.

I tried to get some debug output from mailscanner using some of the
offending mails (all of them are marked by our virus scanners). The
last lines are:

format error: can't find EOCD signature
 at /opt/MailScanner/bin/MailScanner line 568
format error: can't find EOCD signature
 at /opt/MailScanner/bin/MailScanner line 568
Can't call method "print" on an undefined value at /sw/sun4_59/cyrus-2.2.10/lib/
perl5/site_perl/5.8.6/MIME/Entity.pm line 1824.

The corresponding lines from Entity.pm are:

    ### Singlepart type with parts...
    ###    This makes $ent->print handle message/rfc822 bodies
    ###    when parse_nested_messages('NEST') is on [idea by Marc Rouleau].
    elsif ($self->parts) {
        my $need_sep = 0;
        my $part;
        foreach $part ($self->parts) {
            $out->print("\n\n") if $need_sep++;
            $part->print($out);
        }
    }

I think the Mailscanner process gets aborted and the same mail are
processed again from another process. Until now i didn't find a
single message to reproduce the problem, perhaps tomorrow ...
