Make the block by HELO/EHLO checkbox actually work!! :)
There is a feature in the system that appears to allow blocking by HELO/EHLO but it is completely non-functional. This would be awesome to help stem brute-force attacks!
Hello,
We have not been able to find any issues with the host screening functionality. One thing to keep in mind is that, the system intentionally does not reject sessions until after the MAIL command so that authenticated sessions can be exempted from it. If you are having problems with dynamic screening please contact our support team so that we may assist you. All of our support options can be found at www.altn.com/support.
Thanks,
Arron
