Exchange 2007 subdomain not able to receive emails

[acabezas7]

I have a sub domain @fax.companyname.com and I have created MX records and A record for this name to resolve my mail server. I am setting this up for users from another domain can send faxes from outlook to any fax number using the syntax 3477747103@fax.companyname.com

We already have a exchange connector between our exchange servers. When a user on their domain sends an email to that domain name it leaves there exchange server but gets blocked on my end when received. I have ran my receive connector in verbose mode and these are the errors I see on the logs.

Any idea what could be blocking it on my end. Is it that this sub domain is not a trusted domain on my exchange server? Thank you so much

You probably need to set the connector to accept any recipient. See this article:

http://www.omegaprojex.com/index.ph...llow-external-relay-in-exchange-2007-or-2010/

Sorry for the long url. I'm unable to use tinyurl.com at work.

When all else fails, read the book!

You did add fax.mycompany.com as authoritative to the Accepted domains list in your Org/Hub settings, right?

From what I'm seeing, your server thinks that the remote sender is trying to use your server to send the email/fax to yet another external server, when it should be recognizing that the fax.mycompany.com address is a local domain that it can deliver to. If it knows that it is a local domain, it shouldn't throw a relaying error.
