asked on

how do I allow email to be delivered when to our domain when the end user is receiving 5.7.1 Sender ID (PRA) Not Permitted

recently due to a hack we increased security by toughening up our sender id and spf records.
After doing this some emails from trusted clients started to receive the following errors:

************
There was a SMTP communication problem with the recipient's email server (my eamil server).  Please contact your system administrator. <theirdomain.com #5.5.0 smtp;550 Backend Replied [aff9cef4.0.423884.00-2094.655674.p02c11m074.mxlogic.net]: 5.7.1 Sender ID (PRA) Not Permitted (Mod>
*************
Also their reverse dns does not match SMTP banner, but Im inclined to believe that its our sender id blocking them.

will changing the filter to accept also allow the possibility of domain spoofing to take place? I dont want to loosen security to allow one person to send email.
I guess you have a third option which is to Archive, so it neither rejects not allows to go through. It will put it in a special folder, where you can choose which one to release and which one to delete.
