I use Postfix for my MTA, and like I said I swear I used to see the DSNs
before, but this round I’m not seeing them. One wrinkle is the fact that I’m
hosted on Linode, and one of the big RBL providers has a bug up his ass about
Linode and so instead of just blacklisting the instances that produce spam,
he’s basically blacklisting all of Linode. And because of that, I relay my
outgoing mail through a friend in Norway. I wonder if that relay has started
swallowing the bounce message while still returning the bounce status?
I did, however, get a plaintive email from a little old lady on the list who
said “But I don’t want to unsubscribe from the list”. So I guess she at least
got her “you’ve been removed’ email. Which again, increases the mystery.
This particular round of “too many bounces” disables all happened in a matter
of an hour or so, preceded a couple of days earlier by some others. Does
mailman bundle those up and process them all in a batch?
