ML Mail delivery to @suse.de and @o.o broken
anna.i.o.o can not deliver mails to mx*.suse.de, for example
2020-06-23T19:21:30.019137+00:00 anna postfix/error: 023F5298C4: to=<cboltz AT opensuse.org>, relay=none, delay=0.01, delays=0.01/0/0/0, dsn=4.4.1, status=deferred (delivery temporarily suspended: connect to mx1.suse.de[220.127.116.11]:25: Connection timed out)
mailq currently has 26k mails - and a quick look shows that many of them are related to this problem.
FYI: I've increased the queue lifetime to prevent mail loss of these delayed mails (default is 5d):
bounce_queue_lifetime = 10d maximal_queue_lifetime = 10d
- Status changed from New to In Progress
- % Done changed from 0 to 50
FYI: looks like this was an issue with the new network equipment, deployed over the weekend. SUSE-IT fixed it after raising the urgency in the internal ticket system.
Mails are getting delivered now. One by one. Hour after hour. It will clearly take some time until the ~36k Emails will get delivered - but they will get delivered. Thanks to you, Christian!
Leaving it up to Ricardo to finish/close the ticket, once every fall-out is solved and systems are back to normal.
