I do have control over gandalf - a VPS server (so that much, at least). Not sure how I would obtain an "actual raw message" other than what I received from the sender as a subscriber myself. The server uses Exim and is a CPanel installation.
Seems like I get these bounces a couple a day and so far not often enough increment to suspend the guys that these are bounced from. thanks for your help! /jim On Sat, Apr 22, 2017 at 7:47 PM, Mark Sapiro <m...@msapiro.net> wrote: > On 04/22/2017 07:30 PM, Jim Dory wrote: > > I have a couple members of our list whose remote mail servers reject some > > of our messages because of what appears to be text formatting in the > > messages.
