I have Exchange 2000 with the latest service packs.
I am having trouble sending mail to certain domains.
I have installed the MS SMTP Diag tool from
When I run this utility I get the following error
Connecting to the server failed. Error : 10060
Failed to submit mail to mail.domainname.com
However, if I try sending mail to the same recipient using my personal Hotmail account it gets through OK.
In Exchange System Manager I have added an SMTP Connector & changed the setting to send HELO instead of EHLO & left the other settings as default.
Most mail flows through OK, but there are certain domains that will just not accept mail from my server.
Any ideas ?
