We're having a problem that one of our countries major 'mother' ISP's (KPN)
with multiple daughters has messed up their e-mail system in such a way that
it is rejecting e-mails which have a DSN request. All e-mails which have a
DSN request on them are failed with a 550 recipient rejected message. Is
there any way at tge groupwise level to strip the DSN for just those domains
or would it be better to see if I can strip it at the gateway to the outside
I'd rather not disable DSN as a whole because it is actually used here by
our employees.
We had it before but we thought they fixed it right around the time we
migrated to GW8, but in hindsight this was because DSN's were broken in GW8,
but they started working again with SP1.
