TNEF corruption and crashes and massive problems after upgrading to 4.78.9

Fri Aug 28 09:44:18 IST 2009

Hello all.

I was glad to see that the processing db feature to prevent mails which
would crash mailscanner or one of its module was added in the version from
topic.

However after having run this beta for about 2 weeks, I got massive problems
in contrast to the old version I ran before that (4.74.16-1)

Before I used to get a problematic mails which would hold up the queues
maybe once every 6 months or so, while very annoying it did not happen often
at all.

However since I upgraded, I get about 2-6 every day which are placed in the
processing queue.

So on the up side the processing database is doing precisely what it was
made for, preventing MailScanner crashes from holding up queue’s, as the
problem mails are removed after X number of tries.

The downside is of course that these mails are not delivery, and its almost
always ham mails, so it’s annoying for the users.

It seems from my first look aty the problem that it seems to be the tnef
expanding part that fails. Now I’ve always used:

Expand TNEF = yes

Use TNEF Contents = replace

TNEF Expander  = internal

Deliver Unparsable TNEF = no

Which has worked well both in terms of not crashing and removing those
annoying winmail.dat files.

Are these variable values the recommended values? What are everyone else
using?

And is anybody using the new beta with success on a faily active system
(like at least 1000 mails a day)

My systems details are below:
