This has happened before to this member. They are a member of the group, with only this address and sometimes it bounces back to them and sometimes it doesn't. Retrying the same email seems to work after the first bounce, but this is clearly a PITA for Jim.

He sent that message to two groups, trufen and fm-mirrorarchive. He's not subscribed to fm-mirrorarchive, which caused that error. The message did go through to the trufen group. 

The error message can be better, and it will be, but it will require some significant rewriting of that part of the codebase unfortunately.

Thanks,
