Exchange 2010 SMTP Relay - 2nd internal domain name - HELP!!!

    Question

  • Hi,

    Hoping someone can help me with a little issue I have please?

    Our Exchange admin has left the firm and I have picked this up with very little experience of Exchange.

    In short we have moved our internal SMTP relay from 2003 to 2010 and come up against some issues, all of which I have overcome bar one, our Finance team send various emails from their billing system to users and themselves in various ways, Anonymous, sending as an internal user to the same internal user but relaying with an admin account etc etc.

    They also send emails to internal users as a completely different made up but relavant name to the actual firms domain, for example, our internal domain is company.com and all in internal users SMTP address is company.com, however they need their finance system to relay to users as an address from finance.com, this isn't a mailbox it's just a name their system uses and sends via our internal smtp relay/receive connectors.

    I have setup a new internal receive connector that applies to only their finance subnet allowing anonymous, however I'm at a loss as to how to allow the finance.com domain to relay to our internal users, I'm assuming I need to create an authoritative domain or similar but do not just want to go playing around on a live environment.

    Any help would be greatly received.

    Many Thanks

    Steve

  • Hi Steve

    You shouldn't have to do anything.  The "from" part of the email address is set by the sending system so I guess your finance team has an SMTP client that is sending as this address.  Unless your users need to receive email at a different domain name then you do not need to add an accepted domain.  If they are allowed to relay through you Exchange 2010 server then that should work for them, if it doesn't then the relaying is not configured correctly.
