Yes correct.

Yes it is but remember and I’m assuming this is relevant. Not all mail consistently fails. Only some.

This works for other emails ;-)

I do now but my problem doesn’t relate to an actual error message per se.

A reminder many emails go thru this filter without issue.
This shell script is now running my filter using strace and I capture the log and for those emails that still error within exim I never
see any activity in the strace log for those messages.
#! /bin/sh
TODAY=`date "+%Y%m%d"`
TODAYTIME=`date "+%Y%m%d%H%M%S"`
echo "filter.sh $TODAYTIME" >> /home/elastica/filter.log.$TODAY
/usr/bin/strace -tt -o /home/elastica/filter.log.$TODAY -A nice -10 /usr/bin/perl /home/elastica/perlscripts/filter.pl
for file in `/usr/bin/find /home/elastica -name "filter.log*" -print | grep -v $TODAY | grep -v "filter.log$"`
do
/usr/bin/gzip -q $file
done
