Dear IredMail Users,

For about 2 or 3 years iam user ing iRedMail. The software is working great without big problems.

Now a days more people in my network are using this mailserver. The only big problem is that there is comming more and more spam to the mailserver from random emailaddresses like:

1. abigail@bikkabeansreevati.com
2. siemrkhjmdmjanssen@pzoom-de.com
3. miramkfwfydverhoeve@motorovapila2cz.com

These email's arent valid and the only thing i am seeing is spam when i open it (the content). Is there any possible way to prevent that this kind of emailadresses are getting blocked. Like a "content filtering" program.

Some of these crap email are getting send to one of the info@domainname on my mailserver which are forwarded to a Outlook, Gmail or other mailservers. Those mailserver reconsizes these emails as crap but not my mailserver.

Any suggestions that Postfix is able to scan the body / header content for junk to prevent that this kind of e-mails ends up in the users mailbox.
