Dr. Web is a Russian anti-virus utility that comes bundled with Plesk. It’s good and it tries to keep the bad guys out.
To keep up with all the mutations out there it tries to update itself frequently. B default, Plesk sends the system admin an email when this happens – no matter if Dr. Web was successful or if there was a problem.
This is what a sample email looks like:
/etc/cron.daily/drweb-update: Dr.Web update details: Update server: http://update.us1.drweb.com/plesk/700/unix Update has begun at Thu May 17 03:37:07 2011 Update has finished at Thu May 17 03:38:16 2011 Following files have been updated: /var/drweb/bases/drwdaily.vdb /var/drweb/bases/drwtoday.vdb /var/drweb/bases/dwmtoday.vdb /var/drweb/bases/dwntoday.vdb /var/drweb/bases/dwrtoday.vdb /var/drweb/bases/timestamp /var/drweb/updates/timestamp
Multiply that email by the number of servers you’re looking after, and you’ll soon have an overflowing inbox.
Here’s the solution: tweak a system file and divert those emails to nowhere.
