Sorry to respond on list, but in the past few days I've received "warning" messages saying that digests (X4u and g4) have "bounced", and that to make certain I should continue receiving the digests, I should respond to the notifications. Every time I've responded to one of these warnings, IT bounces. Here's a snippet of such a message: > ----- The following addresses had permanent fatal errors ----- > <x4u-subscribe at lists.themacintoshguy.com> > (reason: 550 Host unknown) > > ----- Transcript of session follows ----- > 550 5.1.2 <x4u-subscribe at lists.themacintoshguy.com>... Host unknown (Name > server: lists.themacintoshguy.com: host not found) Still, the digests continue to arrive (although I'm not sure I'm getting them all. Can someone (listmom?) explain this?
