Hmmm, you'd have to be careful about this. When mail gets gatewayed from UUCP to SMTP, a ! address gets automatically changed into a @ address to obey the protocols. When mail gets gatewayed from SMTP to UUCP, the transformation goes backwards, but it's still automatic. You'd have to complicate the transformation some: SMTP->UUCP user@site -> site.local.domain!user rather than site!user UUCP->SMTP site!user -> user@site.UUCP rather than user@site This would certainly have some advantages. The behavior where site!user and user@site are treated identically (which seems to be what most mailers have implemented) causes some problems when a UUCP site name is the same as a machine name in the local domain. --- Tom Fitzgerald Wang Labs fitz@wang.com 1-508-967-5278 Lowell MA, USA ...!uunet!wang!fitz
