That's in the zone file of the provider who is hosting your DNS. For example you can check MX records using NSLOOKUP. If you tell NSLOOKUP to query for Any records, you will probably see SPF records.
Speaking of DNS, did you check whether your server is using correct DNS servers? Also check to see if your server has anything in the HOSTS file that could be pointing mail in a wrong direction. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of John Aldrich Sent: Friday, July 29, 2005 9:17 AM To: Exchange Discussions Subject: RE: Problem sending to outside email address Where's that?

If there is, verify that both mail servers are designated as being valid originators for your domain. -----Original Message----- From: John Aldrich [mailto:[EMAIL PROTECTED] Sent: Thursday, July 28, 2005 3:45 PM To: Exchange Discussions Subject: RE: Problem sending to outside email address Sorry, you lost me.

That's not the problem. It's set to "organization." As I say, THIS problem has been tracked down to the mail recipient's side, however, since we have this problem occasionally with other domains, etc, I thought it prudent to investigate further.

I'm having a problem here that I'm hoping someone can help me with... We've got two mail servers. On one, we can send to a particular 3rd-party (external SMTP account) with no problems. On the other, the same email address gets an "undeliverable" response within about 30 seconds when someone on the other server sends that address an email. i.e: Person on server 1 sends email to address, email goes through. Person on server 2 sends email to the same address gets an "undeliverable" almost immediately. This has happened before and it's always been server #2 that's had the problem. I did not install/build either server and I have inherited these servers. Not to mention the fact that I have no formal Exchange training... *sigh* John _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/read/?forum=exchange To subscribe: http://e-newsletters.internet.com/discussionlists.html/ To unsubscribe send a blank email to [EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] To unsubscribe via postal mail, please contact us at: Jupitermedia Corp.
