We have a working Davmail setup, but somehow the DSN are not getting through. Our setup works with an exchange server 2003 that sends everything to a postfix server.
I can see in the logfiles of the postfix server that messages sent via outlook are working with a delivery status notification. With thunderbird through davmail this does not work. (New message -> options -> delivery status notification)
Davmail version 4.4.0
Thunderbird version ESR 17.0.11
Via the outlook web interface I can send a message with a DSN, and this works correctly.
Any logfiles I should attach?
