Pigeonhole redirect is adding a message-id header when it already exists

[Sébastien Riccio]

>You wrote in the original email the message was rejected. Sorry I don't have login access to my gmail test account anymore since the google @#$%@#$% wanted to have me add a phone number.

In my original post I said that gmail was rejecting the forwards because 
of duplicate headers, and that the duplicate header seems to be a 
Message-ID added by pigeonhole when it's "not happy" with the original 
mail Message-ID.

I probably failed to explain the issue clearly and sorry for that.

Thank you anyway for trying to help :)
