I've taken over managing a server set up by someone else now uncontactable, while managing to work out most faults / changes needed this one is stumping me. Awstats is running on the machine and sending messages via exim4 to a user every time it runs an update. The user account has been deleted and so the exim4 main log files are filling up with message delivery errors, which firstly hinders meaningful log analysis for anything else and secondly uses up quite a lot of space (it grew to 22GB unattended, panic!)

I've been through all the conf files in /etc/awstats and can't seem to find any mention of this user account. Google just turns up results about how to use awstats to parse exim4 log files.

So the questions is where is this setting (on debian) likely to be?

Cheers in advance
