[MM3-users] Is there a way of recording bounce messages?

Hi.

I recently had an incident of all gmail.com members being bounced off one email list (around 180 subscribers). The messages recording the bounce don't include the original DSN. Is there a way of getting the DSN recorded? I'm sure it will give me some nonsense Gmail refusal message but I would like to identify if messages are bouncing for specific users, or if I am harming my reputation by sending to disabled accounts etc.

Thanks. Andrew.
