Hi,
maybe my problem is similar to this: Changed notification mailadress but still got the older one
Zammad 3.6.x
Ubuntu 20.x
Browser: Firefox
I got an error when setting up the system. Sendmail does not work. Now when I try to change sendmail to smtp I get the same error (I think).
554 5.2.0 STOREDRV.Submission.Exception:SendAsDeniedException.MapiExceptionSendAsDenied; Failed to process message due to a permanent exception with message Cannot submit message. 0.35250:0A002085, 1.36674:0A000000, 1.61250:00000000, 1.45378:02000000, 1.44866:5E200000,
…
0.21966:8A250000, 4.30158:DC040000 [Hostname=VI1PR0402MB3823.eurprd04.prod.outlook.com]
I have put in the same login information I use with the E-Mail Account. There it works perfect.
I also found this : https://stackoverflow.com/questions/54784431/unable-to-send-smtp-mails-using-office365-settings
There the answer is: username and from adresse must be the same.
So if I want to change the notification from sendmail to smtp. Maybe the routine does not store the username as from adress?
If anyone has an Idea it would be wonderful
