The following people listed on the sample error message below have been on my list for years, with no problems, then one day, I started seeing these error messages coming in. They can't receive email from my Listserv (WUVMD.WUSTL.EDU), however they are able to receive email from everywhere else, including other listservs they belong to. I have been in contact with my listmaster, and the postmaster at the other end.....to no avail.....no one has been able to explain why this problem is occuring, much less what needs to be done to fix it. The duration of the problem is approximately 1 month. I have 1800 people on two different lists and have no other similar error messages coming in. I've seen vague references to similar problems as I have viewed the archives of the LSTOWN-L list, but none of the previous discussion was all that helpful If anyone has suggestions or useful comments to help me resolve this issue, they would be greatly appreciated.
