I have a subscriber who is getting errors on administrative Listserv mail from SMTP on our IBM _and_ from LSMTP on our Alpha. The only book I have here (1) with a definition of what's valid in a FQDN says the underscore, as used below, is legal. I'm also not clear how it got to Maelstrom from SMTP3 if the error is at our end. -Kary (1) The Internet Message closing the book with electronic mail Marshall T.
