Hello everyone.

I´m receiving e-mails with warning messages like this below, instead of the

"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."

My server is a Ubuntu 16.04.5 LTS with MailScanner 5.1.2, Mailwatch 1.2.12
and MariaDB 10.3.

Anyone can help me?
