I have decom'd an old exchange 2000 email server. And replaced it with a newer System running exchange 2000. name of old email server is mail and the new email server is mx1.
After moving all jobs, mailbox's, ect over, uninstallng esm from MAIL I am having 1 problem. It seems that I am unable to pass any email to or from AOL from my new MX1 exchange server. I have put in spf record in my DNS, I have assured that I have mx1 in my telco provider dns. I have even requested and been accepted into AOL's whitelist. And yet no emails are being passed sending or receiving. I am not on anyblacklists. I dont have open relay either.
in event viewer I have recieved.
event ID 4000 MXExchangeTrasnport
Message delivery to the remote domain 'aol.com' failed for the following reason: The connection was dropped by the remote host.
event ID 4001 MXExchangeTrasnport
The SMTP verb which caused the error is 'MAIL'. The response from the remote server is '521-EHLO/HELO from sender x.x.x.75 does not map to mx1.x.lan in DNS
521-sending machine n'.
our outgoing email port is x.x.x.2 as well. x.x.x.75 is the firewall.
I am totaly lost, any help is greatly appriciated.
