  We first started getting bounce notifications around 7 hours ago, I'm surprised it took this long for Postmark to announce the service issue.

  We're seeing responses like this in our logs:

  smtp;550 5.7.1 Service unavailable, Client host [<ip>] blocked using Spamhaus. To request removal from this list see https://www.spamhaus.org/query/ip/<ip> (AS3130). [DM6NAM04FT060.eop-NAM04.prod.protection.outlook.com]

  Postmark was bought out in May. Just a coincidence, or possibly co-mingling IP addresses with the new overlords?

  I wish it would be permanent, all of these “marketing” and “advertising” companies just produce things that fill out inboxes with junk.

  Good.
