How can we improve?

Improve Dynamic Screening

It would be great if we could block ips which are sending to unknown recipients or sending confirmed spam into a specified period of time.

i.e. if one IP sends more than "X" confirmed spam mails in less than "Y" minutes, then block that IP for "Z" minutes.
If one IP is proving email addresses, and causes "X" recipient unknown responses in less than "Y" minutes, then block that IP for "Z" minutes.

Hello,

Thank you for sharing your idea with us.

MDaemon is capable of blocking IPs that cause X recipient unknown responses. To configure this open MDaemon and go to Setup / Security / Dynamic Screening. Enter a value in the “Block IPs that cause this many failed RCPTs”

MDaemon is not currently capable of blocking IPs that attempt to send more than X confirmed spam messages. This could be a dangerous feature if your spam filter were mis-configured but we will look into it further.

Thanks,
Arron
