Hi Julian,

the failure happens only with some messages, not all.
The attached archive contains some example messages.

Thanks for help :-)

Does this happen with all messages, or only some?
Can you isolate a single message that causes this problem for me please?
I would suggest using "Archive Mail =" to archive all your mail and then
use the logs to identify a particular message that causes the problem to
be logged, and one that doesn't cause the problem.

It is essential that you archive as "Raw Queue Files".

If you can then send me one message file that causes the problem, and
one message that doesn't cause it, I can take a look and fix it.

I haven't played with Postfix 2.3 much yet, so have little experience of
it. This is clearly another hurdle Wietse has created for my benefit :-)
