Denial Of Service attack

[Marcelo Machado]

Hi everyone.

Many users of my domain are receiving the message below and the
original message is lost:

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/5106/5B02C7C002C8.A3986/nmsg-5106-92.html

In log mail.log the correspondent error is:

"Content Checks: Detected and have disarmed KILLED tags in HTML message in"

Anyone can help me?
