I have two exchange servers on one domain, each with their own email address scheme.
ExchangeServer1 = firstEmailAddress.com (exchange2003)
ExchangeServer2 = secondEmailAddress.com (exchange2010)
Domain = mydomain.com
I am getting errors from users sending from email firstEmailAddress.com as follows:
Mailbox unavailable. No reverse name (PTR) for your sender IP (ip address of ExchangeServer2).
I believe this to be in the send connectors so here is the configuration on ExchangeServer2 (exchange 2010)
CompanyExchangeServer1 - Disabled
All outgoing mail - properties>Address Space:
Type = SMTP
Address = *
Cost = 1
It looks like ExchangeServer2 is handling all outgoing emails and throwing an error because the rDNS does not match.
I need to separate the exchange servers as much as possible because ExchangeServer1 will eventually go into another building.
I think that I need a connector for ExchangeServer1 with the address of firstEmailAddress.com and one for ExchangeServer2 with the address of SecondEmailAddress.com
Is this correct and do I create both on ExchangeServer2?
