You need to use the "accept_unresolvable_domians.m4" macro included with your sendmail source code. The page "http://www.sendmail.org/virtual-hosting.html" will get you started on how to build sendmail.cf from m4 macros. [Hint:- FEATURE("accept_unresolvable_domains")dnl ] Although by doing this you may expose your host to abuse by spammers since they often use temporary (therefore probably unresolvable) addresses. hih nick@nexnix >-lz > > >______________________________________________________ >Get Your Private, Free Email at http://www.hotmail.com no thanks :) > >
