Anyone else on Aussie Broadband static IP space having trouble receiving email
from (some) Proofpoint outbound servers?
I am currently unable to receive some important email because SMTP (TCP)
connections are apparently timing out between the outbound ProofPoint SMTP
relays and my MX host "mx1.imrryr.org" (static IP on Aussie Broadband's
network).
The sender receives a delay notification (below) and email never gets through.
My MX host is reachable from most other networks (servers I can access in Munich
and Los Angeles, and routine incoming mail from other sources).
But some email, which was getting through as recently as 2024-05-23
