I'm curious about that myself. Doing a reverse against our DNS servers for our 209.15.194.101 and .112 mailservers returns the correct PTR entry. Against other servers sometimes fails. So I suppose it has to do with getting our colo facilities nameservers on board if they're considered authoritative.
We do have the .112 record set up with them already, but not the .101 IMgate machine. Just set it up. We'll see if it makes a difference. -Ron > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of > Todd Holt > Sent: Monday, October 08, 2001 10:44 AM > To: [EMAIL PROTECTED] > Subject: RE: SPAM: RE: MISSING_REVERSE_DNS:RE: [imail] Upgrade > > > I recently installed Declude Junkmail and set it to add a > header (ie.
