Your e-mail and news software should know about the masquerade too. The "MYNAME=astph" trick is only at the UUCP level, not at the e-mail or news level. To get e-mail to work right, mail will still have to leave your system with "From ... remote from astph" and "From: xxx@astph.UUCP" in it. If you put in "...remote from crafty" and a neighbor tries to bounce it, it will get confused. News should make sure that locally posted articles get "Path: astph!xxx" and "From: xxx@astph.UUCP" rather than crafty, or bad things will happen: people will be unable to reply to your articles, and your neighbors will feed you things that you've just given them, because they don't realize you've already gotten it.
