Auto Response failed: Can't send message: 550

[catweazle]

Preconfigured auto response mail works fine.

Created my own and got this error-message:

OTRS:

Can't send message: 550Enter message, ending with "." on a line by itself.

Maillog:

So checked the database table "auto_response" and the fields but could not find somesting special like unhealthy characters.

I made a new auto response mail via otrs admin webinterface and then just copied (update) all data (excluded the id field...) fields from the working preconfigured autoresponse over my manuel created one.

But it is still the same error...

##edit###

found this in messages:

aDate machine OTRS-CGI-42[9157]: [Notice][Kernel::System::Ticket::Article::SendAutoResponse] Sent auto response (SendAutoReply) for Ticket [421682292831] (TicketID=148, ArticleID=) to 'xxx@xxx.xx'.

So there is no ArticleID in every auto response mail, not even in the working once
