Guest vesago73 Posted August 21, 2007 Posted August 21, 2007 We have two servers in our DMZ. Server A is running Windows 2k3. Server B is running Windows 2K. Both of them have a small script that sends mail to an SMTP server internal to our network. On the Windows 2k3 server you can refer to the SMTP server using the Netbios name only. When you do that on the Windows 2k server the piece of mail goes out to external DNS and does a lookup on our domain then sends the mail in through our MX records which forces it to go though our Spam filters. If you specify the FQDN of the SMTP server on the Windows 2k server then the piece of mail goes straight to the SMTP server. Is there something in IIS 5.0 that requires a FQDN name versus a Netbios name and if so, is there anything official that says that?? -- vesago73 ------------------------------------------------------------------------ vesago73's Profile: http://forums.techarena.in/member.php?userid=29747 View this thread: http://forums.techarena.in/showthread.php?t=805466 http://forums.techarena.in
Guest Mathieu CHATEAU Posted August 21, 2007 Posted August 21, 2007 Re: SMTP on IIS5 vs. II6 hello, does the 2 box have same suffix dns set up (on the network card or computer tab) ? I don't think iis use the netbios name, but should append the dns suffix (which for the W2K3 may be your internal dns suffix) -- Cordialement, Mathieu CHATEAU http://lordoftheping.blogspot.com "vesago73" <vesago73.2vosfi@DoNotSpam.com> wrote in message news:vesago73.2vosfi@DoNotSpam.com... > > We have two servers in our DMZ.

Guest vesago73 Posted August 22, 2007 Posted August 22, 2007 Re: SMTP on IIS5 vs. II6 I checked and everything on there is the same. When I telnet this is what happens. Both servers are on the same subnet with the SMTP relay server. When I telnet from the Windows 2K server to the netbios name of the SMTP server it responds with our MX Records response. When I telnet to the SMTP server using the FQDN it responds with the actual server info. When I telnet from the Windows 2K3 server to the netbios name and the FQDN of the SMTP server they both respond with the actual server info. -- vesago73 ------------------------------------------------------------------------ vesago73's Profile: http://forums.techarena.in/member.php?userid=29747 View this thread: http://forums.techarena.in/showthread.php?t=805466 http://forums.techarena.in
