Again the "classic" problem sending to AOL.com
Hi All,
I know the features required by AOL (http://postmaster.aol.com/trouble/mailer.html) and I have followed these excellent tutorials at http://www.amset.info/exchange/dnsconfig.asp and http://www.amset.info/exchange/smtp-connector.asp but I still have the "classic" problem sending to AOL.com.
I have Exchange 2003 SP2 + W2003 DC server + Popcon pop3 connector. I have the Virtual SMTP server forced to use external DNS (due problems with exchange and non exchange users). Then I can send OK to all places, except AOL.com that is allways retrying.
It seems that all is checked ok. As I am at DSL line with static IP and my ISP can't add my DNS reverse setup ok, I have setup a SMTP Connector only for AOL domain. I also have configured my SMTP Virtual server propierties with mail.mydomain.com (these name is correct because if you type this from WAN you will get to my IP). I put mail.myhosting.com or its Ip with [ ] and with its SMTP authentification detail login etc.
At the queue list I see that the AOL pending emails are changed to another queue list "Relay for Aol.com [217.xxx.x.x.x]" But I get error: the remote server do not respond to connection (translated to english, sorry). I tried too with the server name of ISP mail server and the same. All AOL.com messages are still re-trying.
Any ideas? Thank you all

Hi Sembee
I think I have configured ok the SMTP connector, I tried with its hosting company domain name, and with its IP [ ]. I also have basic authentification (this server needs it) configured.
Do you know any "open" or free relay for doing this tests? I think my smtp login and pass are well configured but...
Thanks!

An open relay is exactly that - an open relay, and therefore don't exist (on purpose anyway).
Can you telnet to port 25 of the address that you have entered in to the smtp connector?
telnet mail.hosting.net 25

Hi,
I mean a "open" SMTP without authentfy for doing tests... Anyway:
I test:
telnet mail.mydomain.com 25:
I get:
220 mail.mydomain.com Microsoft ESMTP MAIL Service, Version: 6.
0.3790.1830 ready at Wed, 5 Jul 2006 15:59:55 +0200
If I test this:
telnet servername 25
I get the same:
220 mail.mydomain.com Microsoft ESMTP MAIL Service, Version: 6.
0.3790.1830 ready at Wed, 5 Jul 2006 15:59:55 +0200
Then I suppose this is ok?

Did you enter mail.mydomain.com in to the SMTP Connector?
If so, that is wrong. It should be your ISPs SMTP Server. At the moment you are just routing the traffic back on itself.

That DNS change doesn't do any harm, so you can leave it in place.

Thanks both

Thank you for your information. I have followed method 2 (due I do not have any cisco firewall). I have installed Support Tools and from promtp I insert: dnscmd /config /enableednsprobes 0
I get that the command was ok and registry enableednsprobes was successfully reset, but it fails again.
If I try without extra SMTP connector y get "Error SMTP protocol"
If I try using extra SMTP connector y get "the remote server has not respond to connection"
Any ideas?
