[Mimedefang] Perl problems with Mimedefang 2.1 on Solaris 6 : Perl process did not finish

[Stephane Lentz]

Hello, 

I've installed sendmail 8.12.1 with Milter support and MimeDefang 2.1 on
a Solaris 2.6 system.

I use the "Suggested minimum-protection filter for Microsoft Windows
clients" but when I send a test message with some.exe  attachment 
the message is not "filtered" : it passes through and only 2
Mimedefang Warning headers gets added :

Dec  3 11:58:10 nsfws5 sendmail[28703]: fB3Aw9gA028703: Milter add:
header: X-MIMEDefang-Warning: Perl process did not finish
Dec  3 11:58:10 nsfws5 sendmail[28703]: fB3Aw9gA028703: Milter add:
header: X-Scanned-By: MIMEDefang 2.1 (www dot roaringpenguin dot com
slash mimedefang)


It seems that the source of the problems is the "Perl process did not
finish" message (coming from mimedefang.c when the UNFINISHED file 
was not removed).

Is is some timeout-related problem ? Any hint to get rid of this ? 

I recompiled Mimedefang with DEBUG support and got this :

I have also another problem : when I kill and restart mimedefang
and then sendmail I have to wait before connections are accepted
(for a couple of minutes I get : 451 4.7.1 Please try again later). 
Any optimization parameter ? 


Thanks. 

Stephane. 

PS : the CPAN has new versions for various perl Modules. 
I installed MIME-Base64-2.12, IO-stringy-2.108n, libnet-1.0704,
MailTools-1.41 and MIME-tools-5.411.

I checked the filters with perl -cw (perl 5.005_03).
I invoked mimedefang with this command : 
/usr/local/bin/mimedefang -n 2 -f  /etc/mail/mimedefang-filter   -p
/var/mimedefang.sock
