At the risk of wandering a little too far off topic: yes, it's not the quality
of your connection, it's the fact that it's in a residential IP block. I have
what might be termed "god tier" 10Gb fiber and hardware to do the hosting (I
run the Dovecot here in the house and LMTP incoming messages over a private
network) but SMTP deliverability has so many factors. One of those is the
originating IP reputation; being in a residential block in and of itself puts
you on several DNS RBLs. The big email providers where you might be trying to
send messages, like gmail and Microsoft, will simply reject you out of hand.
I spent over a decade dealing with both sides of this, rejecting spam on the
one hand, needing to deliver our service's messages on the other. It's ugly out
there.
The best thing to do is stand up a box in a hosting environment that's got a
relatively "clean" address space and send messages from there. And while you're
at it, might as well use it for inbound, too.
That's what's probably going to have to happen for the list itself: a host VPS
container on a relatively neutral reputation network sending and receiving
messages.
