It can, but it's definitely a double edge sword. Depending on the way the remote MTA works, I've experienced emails being delayed for quite sometime. I had a lot of users requesting to be removed from the graylist, and eventually decided to drop it. When you're waiting for the confirmation of a PO from a new vendor on raw materials you need for a batch being made tomorrow it can be very frustrating :) They MTA will let the remote client know the email was rejected, or the local client can go into SPAM folder and find the email, with graylists, the sender nor the receiver may realize the status of the email. > > Delay suspect IP long enough that by the time they retry, if they do, they > are on half a dozen RBL and score high and reject. > > Sent from my iPhone > >> On Jun 17, 2016, at 13:23, Reindl Harald <h.rei...@thelounge.net> wrote: >> >> >> >> Am 17.06.2016 um 02:57 schrieb Alex: >>>> For example, 212.227.126.135, scores 4 out of a 100 on senderscore.
