I'm wondering if it's possible to limit number of emails allowed from a specific email account on Exim (maybe set a 20 email per hour limit for ab@test.com).
I'd like to see if I can use this as a way to control spam.
I appreciate any direction on this. Thank you.
Thank you a lot for your answer. I will checkout the Systemajik link. – Ugorji Nnanna – 2013-07-21T20:05:16.440
Also greylisting can help.
