Hi, Barb- Note that the admin address SHOULD be PAFRANKL-admin@rootsweb.com and that there is no period at the end of the address. That is why the message bounced -- and shows as being "malformed" because a period on the end is not part of a proper email address. Try sending the message to the admin address with no period on the end and it should go through. Joan In a message dated 6/14/2010 9:55:34 P.M.

The reason for the problem: 5.1.2 - Bad destination host 'DNS Malformed Query Error looking up rootsweb.com. (MX).' How, then, do I reach the list administrator? Barb in BC
