Thanks for the helpful tips on finding why I continued to get error messages on a person I'd already deleted from the list. What I did: I checked the header carefully and noted that the host address changed from m4.sprynet.com to sprynet.com in some of the error message. I then checked a list review for all members with a sprynet.com address. I found one that had a member address that was a partial match to the original address. original: [log in to unmask] found: [log in to unmask] The member names differed. So I sent email to this new address and it bounced/created an error message almost the same. Deleted that address and haven't had a problem with that particular error message since. I should have thought of it before -- but the suggestions helped -- sometimes you can't see the trees for the forest.
