I upgraded MailScanner several months ago to v4.85.2-3 and now
v4.86.1-1. Often I am getting the error message:
MailScanner was attacked by a Denial Of Service attack, and has
therefore deleted this part of the message. Please contact your
e-mail providers for more information if you need it, giving them
the whole of this report. Attack in:
/var/spool/MailScanner/incoming/20499/u27Em5eK000564/nmsg-20499-47.html
The file reported in the attack is not there so I am unable to to any
troubleshooting.
I am using a OpenVZ container with Ubuntu 14.04 - 6 CPUs and 12GB RAM.
The messages are causing problems with valid mail messages both incoming
and outgoing.
Is there a way to disable this feature? Any ideas on how to suppress
these messages?
Thanks!
Steve
