Some help with an error message

Hi

I am using Exim4-daemon-heavy with the exiscan-acl patch.

I get the following message in my /var/log/exim4/mainlog:

1BlL0v-0002Tm-IT string_sprintf expansion was longer than 8192

It is while exim tried to deliver a particular spam message. I am also
using SpamAssassin with some extra rules from RulesDuJour. I basically
fetch my mail from the service provider using fetchmail/pop3 which
delivers my mail to my local exim server and checks for spam.

The affect of fetchmail/exim/spamassassin all together created a loop
where the single message keeps being processed in a sense duplicating in
the input/ and scan/ exim dirs.

Manual intervention is always need with a manual delete of the pop3
server and a purge of the input/ and scan/ dirs.

Does anyone know how I can try and solve this one.

Kind Regards
Leon
