we are encountering issues with some users getting error notifications after replying to an email from an external partner:
554 5.6.0. Bounce, id=01761-13 - bad header
cause: "mime version" occurs 3 times
if we check the mail header it does contain "mime version" 3 times
Lotus Domino 9.0.1. FP5
I always assumed this information cam from the mail server and is not altered by the mail client. But can anybody provide me with an overview of this protocol?
