Postfix Script to count the number of 550 no such user here

Leo-G · 05-15-2013, 09:49 AM

I have CRM which sends Auto-replies, I am seeing a huge number of 550 no such user here in the logs, I wanna a script which will count these users and if the Count goes above a certain number it will block the user, I want to avoid backscatter basically, I saw this suggestion on the UCEproc list, But I do not know how to start, so any suggestions are most welcome

turn off or limit auto replies?
Is there no verification mechanism for auto reply addresses?
Seems like there should be.

I cannot turn off auto-replies as we have to intimidate end users that we have received their replies, Limits can set within a timeframe, But my question is with regards to no such user here, I dont want to get blocked by gmail or yahoo for this reason, I also want to learn how such scripts can be written
