Recipients from other domains like "gmail.com" are delivered as expected. Message containing (ae, ue, oe in place of ä, ü, ö) or message containing "ä", "ö", "ü" sent from the providers web-interface are also  delivered as expected.

My wife using the same provider with outlook client is not suffering from this.


Any suggestion would be greatly appreciated.

thx markus


Expected results:

Successfull delivery

Thank you Wayne

I've set "mail.strictly_mime" to true. No NDR. Problem seems to be resolved. No more issues. I'm going to close this case as resolved.
