For about two weeks now, I've been getting random kick backs from a surname rootsweb mail list. This morning, I received two kickbacks before it finally went out on the 3rd try. Nothing different on the 3rd try -- it just went. Anyone else having this problem, or know what would cause it? Here's the excuse given for rejection: ----- The following addresses had permanent fatal errors ----- <woodworth@rootsweb.com> (reason: 550 5.7.1 <woodworth@rootsweb.com>...
