Hello all,

I have a bothering problem on all my OTRS servers: when someone other than the original customer replies to a closed ticket in a queue with follow-up set to reject, an automatic response is sent to both the original customer and the person who wrote the rejected follow up.

But this response gets never delivered, neither to the original customer, nor to the followupper and an error is logged:

Can't send to 'john.doe@domain.com': 550sorry, I don't accept bounce messages with more than one recipient. Go read RFC2821. (#5.7.1)

My question is: why a follow-up-rejected message is treated like a bounce message by the SMTP?

There's a way to get the message delivered to both users?

Cheers, d.
