Notification emails stopped working

[Kriss]

After upgrading our hosting package, notification emails stopped coming through.

We use Gsuite for Business and Ionos hosting.

Using https://trello.com/test_notifications produces nothing in our spam filters or quarantines.

Has anyone else experienced this issue?

Hey Kriss,

We can do a bit more digging into this with you over email. Can you send us a message on our contact form and include a few example emails that are running into trouble?

Thanks!
