Is there a way to set up an External Spammer rule in Security Settings? It would work similar to an Internal Spammer rule, but in reverse.

 

For example, if SM receives >100 messages over a 10 minute period from an external IP, then either throttle that IP or block it for 30 minutes.

 

If this doesn't exist, it would be a nice feature.

Hi Kevin. Have you tried the Declude/Message Sniffer combo along with configuring a few reliable RBLs at the SM incoming connection checks level for anti-spam filtering? These 3 things are what 95% of our customers use and they are very very pleased with the results. If you would like to give it a try, let me know and I can explain how to get started. Thanks.

Hey, just wanted to keep this thread alive. First, let me emphasize that SmarterMail has great spam blocking and filtering capabilities. Just trying to take it up to excellent by adding a few tools such as:

 

Let's classify the above item as a bug (cannot check the box) so that it can be fixed in v15.  I can post this in a separate 'problem' thread if necessary. Thanks so much!!!

Happy New Year!

 

Just following up on this thread. Can a few of the bullets from the top post be implemented in 2018 to help us block spam?

 

Thanks,

Kevin

Just FYI, I am looking to take this to even a level past SMTP

We are looking at moving to pfSense for our firewall.  As i understand it, there is a way to script importing IP addresses to block..  So If we can get smarter mail to generate a list of  IP addresses, or even write our own module to dig and export that list, then we can block the traffic at the firewall, and not even bother with SMTP.  Basically avoid the middle man and get the results directly to the front door guard.
