Terry, you were oh so very very very very very much in the wrong to do that. This is *exactly* as bad as advertising mail addresses of user@host.uucp where `host' isn't registered in the UUCP Mapping Project maps. They are both the same violation -- claiming to be in some domain (naming authority) when you really aren't. One of the duties of a postmaster is to advertise connectivity to their systems to all the networks to which their systems connect. In both cases you're claiming the connectivity (that is, by making your headers read `host.dom.ain.edu' or `host.uucp', you're claiming to be in the naming authority for either `.edu' or `.uucp') but *NOT* *ADVERTISING* the connectivity. -- <- David Herron, an MMDF weenie, <- Formerly: David Herron -- NonResident E-Mail Hack <- <- Sign me up for one "I survived Jaka's Story" T-shirt!
