Hi Jorgen,
Could you provide syslogs from the ASA when e-mail traffic goes through?

Hi,
Could you enable "inspect esmtp" and test? Here is a document for your reference:

From the logs, I dont see anything out of place. Could you run "debug smtp" on the ASA? Note: enable the debug when there isn't a lot of traffic going through the ASA, as it might affect through traffic.
Let me know.
