Sorry missed the bit in the thread where you changed from dynamic to static ;-).
Lets ignore the RBL lists for a bit... Assuming we are talking about mail sent from mail.jetproducts.com using the ip address 67.94.79.66 , By using www.dnsstuff.com is see there is no PTR record for mail. http://www.dnsstuff.com/tools/ptr.ch?ip=67.94.79.66 Location: United States [City: San Diego, California] Preparation: The reverse DNS entry for an IP is found by reversing the IP, adding it to "in-addr.arpa", and looking up the PTR record. So, the reverse DNS entry for 67.94.79.66 is found by looking up the PTR record for 66.79.94.67.in-addr.arpa. All DNS requests start by asking the root servers, and they let us know what to do next. See How Reverse DNS Lookups Work for more information. How I am searching: Asking i.root-servers.net for 66.79.94.67.in-addr.arpa PTR record: i.root-servers.net says to go to dill.arin.net. (zone: 67.in-addr.arpa.) Asking dill.arin.net. for 66.79.94.67.in-addr.arpa PTR record: dill.arin.net [192.35.51.32] says to go to NS2.XO.COM. (zone: 94.67.in-addr.arpa.) Asking NS2.XO.COM. for 66.79.94.67.in-addr.arpa PTR record: Reports ip67-94-79-66.z79-94-67.customer.algx.net. [from 207.155.252.16] Answer: 67.94.79.66 PTR record: ip67-94-79-66.z79-94-67.customer.algx.net. [TTL 10800s] [A=67.94.79.66] I understand yahoo requires a PTR for the mail sender. So get your ISP to add a PTR record for mail.jetproducts.com against 66.79.94.67 or relay via your ISP see the bottom of http://www.webmasterworld.com/forum22/3783.htm cheers Dean -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Tony Nguyen Sent: Wednesday, 31 August 2005 2:23 a.m. To: Exchange Discussions Subject: RE: Yahoo We have a static IP.

Yahoo will be just the start. AOL will be next, followed by an increasing number of other sites. The SMTP Connector is the only solution. I now put these in as default for all client installations I do where they are on a DSL and/or dynamic IP address.

If so you are on a loosing battle. You will be on the dynamic IP address blacklists and not one of the service providers will remove you from those lists. They don't believe that you should be trying to deliver email directly but should be using your ISPs SMTP server. Try putting your external IP address in to this site: http://rbls.org/ Otherwise concede defeat and create an SMTP Connector to send email for Yahoo via your ISP's SMTP server. http://www.amset.info/exchange/smtp-connector.asp Simon. -- Simon Butler MCP, MCSA, MVP:Exchange Senior Systems Administrator Amset IT Solutions Ltd. e: [EMAIL PROTECTED] w: www.amset-it.com w: www.amset.info -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Tony Nguyen Sent: 29 August 2005 18:39 To: Exchange Discussions Subject: RE: Yahoo I have check ordb.org and dnsstuff.com. and it seem fine.
