stripped attachments

Mon Feb 1 19:26:51 GMT 2010

Replace is causing the problem it strips the attachemt(s) entirely. It
had been doing as you state, killing the winmail.dat and leaving the
attachments but it is now deleting both. Yes with No set I still have
the winmail.dat. I will look into changing Exchange to no do that. I
have 0.17	Convert::TNEF showing with MailScanner --v 

Linux spamfilter.sbschools.net 2.6.18-128.2.1.el5PAE #1 SMP Tue Jul 14
07:15:01 EDT 2009 i686 i686 i386 GNU/Linux
This is CentOS release 5.3 (Final)
This is Perl version 5.008008 (5.8.8)

This is MailScanner version 4.76.25

I will test it as instructed as soon as I can get some test messages
together.

With it set to "replace", it should indeed kill the winmail.dat 
attachment but it should replace it with the real file attachments that 
were encoded within it. "TNEF" is an attachment encapsulation format 
invented by Microsoft because they couldn't just be bothered to follow 
the same standards as everyone else. Your best bet long term is to stop 
your Exchange Server generating any TNEF in the first place. The only 
email application in the world that can read it is Outlook, so no-one 
using any other email application can even read your attachments at all.

Is that replacement process happening properly, or are you being left 
with no attachments at all?
What is your "TNEF Expander" set to in MailScanner.conf?
If it is set to some /usr/bin/tnef command-line, do you have the tnef 
binary installed properly?
What operating system and distribution are you running on?
If it is set to "internal" then does "MailScanner -v" report that you 
have the TNEF perl module properly installed?
If so, what version number of the TNEF perl module?

If you have it set to some /usr/bin/tnef command-line, then change it to

the single word "internal" so it says
TNEF Expander = internal
If you have it set to "internal" then replace it with /usr/bin/tnef so 
it says
TNEF Expander = /usr/bin/tnef --maxsize=100000000

Then retry your messages with this new setup (after doing a "service 
MailScanner reload" to make it re-read the new configuration).
Does it behave any differently now?

Jules.
