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.

Could there be something causing an intermittent lookup failure?

Best,

Glenn

Assuming that you do not allow non - members to post do his failed attempts show up in your Activity Log?

We do not permit non-members to post and I only see his successful attempt.

I don't know if it makes any difference, but this was a reply to a previous message on the list.

Best,

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,

Many thanks, Mark. That makes sense. There's a fair bit of overlap between the two groups and cross-posting is not uncommon.

I will let Jim know.

Thanks for all you do,

Glenn
