"Auto-Submitted: auto-replied" causes bounces to Google Groups

Hi,

We recently got a couple of bounces when sending tickets (investigations
and incidents in RTIR) to a customer that had his mail handled by Google.
Mail sent to individuals (through RT) were accepted, group-aliases not.
A bit of investigation on their side (with them getting support from
Google) showed that the messages were rejected because of the header
"Auto-Submitted: auto-replied"

I can filter this on a Postfix level but before doing so … would this
affect RT in any way? Is there any configuration in RT that would
prevent RT from inserting this header?

We’re running RT 3.8.7.

Thanks for the replies,

Koen
