Windows 2019 Standard
SmarterMail Build 7118
New install of SmarterMail - should work as Backup MX.
Messages get deleted in the spool after 2 times trying to connect to the primary (down) mailserver.
Retry times (Settings-General) are set to
5, 5, 15, 30, 30, 30, 30, 30, 60, 90, 120, 180, 240, 480, 960, 1440, 2880
We have the same problem loosing messages on an Windows 2008 running SmarterMail Professional Version 16.3.6915 (production).
Therefore I setup a new SmarterMail server (I thought it's a problem with version 16.3.6915)
As far as I know from the past - when a primary went down, I could see all waiting messages in the spool.
The logs show incoming messages, 2 tries connecting, then ->
17:54:15.784  Delivery for firstname.lastname@example.org to email@example.com has completed (Deleted)
17:54:15.784  Removed from RemoteDeliveryQueue (1 queued or processing)
17:54:16.784  Removing Spool message: Killed: False, Failed: False, Finished: True
17:54:16.784  Delivery finished for firstname.lastname@example.org at 17:54:16 [id:12719010]
Is this a bug?
We did not change any setting on the production server.
