Hi,

I try to setup a sieve vacation auto-reply. Internal it’s working properly. Unfortunately the messages aren’t accepted on the outside:

I assume this is an issue with the mail headers? Can this caused by the sieve script? The internal mail server is connected to a mail relay with two different mail domains.

Best,
