Probably you just need to make sure your sending prefs are set correctly. Often when using a second provider for mail, as you described, you need to have your e-mail client re-authenticate during the sending process. For example, my SBC (AT&T) account needs "auth.smtp" as a prefix for sending. Check with your e-mail account provider for this setting. > From: Doug Burton <mdd867x2 at roadrunner.com> > Reply-To: "A place to discuss Apple's G4 computers." > <g4 at listserver.themacintoshguy.com> > Date: Mon, 13 Nov 2006 00:30:03 -0500 > To: <russells at strodtbeck.org>, "A place to discuss Apple's G4 computers." > <g4 at listserver.themacintoshguy.com> > Subject: Re: [G4] sending mail from OSX Mail App > > > On Nov 12, 2006, at 9:33 PM, russells at strodtbeck.org wrote: > >> >> I use Apple's Mail application for mail..I recently signed up with >> Quest.com DSL internet.
