  • Send Connector for second domain, Exchange 2007 on SBS 2008

    Hello there
    I have been told that you can route email for a secondary domain through a separate send connector therefore allowing a second SMTP banner on your server. Is this true and how is it done?
    Basically I am trying to avoid SPAM issues on Reverse Lookup. If not, is there another way of managing two or more domains and reverse lookup from Exchange 2007 through a single public IP?

    Many thanks for those who can help

    The domain that you are sending email from has nothing to do with the SMTP banner. By the time the remote site can see the email address the email is coming from, the check on the banner/DNS etc has passed and it is too late.

    As long as the SMTP banner matches the PTR on the IP address and resolves to the same IP address, it will work fine.

    It would require more than just an additional Send Connector, as it would need an additional IP address and firewall configuration for everything to match, and there are simply not enough IP addresses in the world for every domain to have a unique IP address.

    Simon.
