Exchange 2010 - Send Connectors

Hi,

I have two Exchange 2010 servers. Both have all roles enabled. I set this up to take advantage of DAG's. The DAG's are working fine, as is email.
I have noticed something though.
My Servers are
Exc1.mydomain.com
Exc2.mydomain.com
I don't have a CAS array set up. I have the MX record pointing directly to the IP of Exc1.
I have been noticing in the message header of some of the sent messages from the server that the second server is referenced. Something like this:
Received: from Exc2.mydomain.com (10.235.10.11) by
Exc1.mydomain.com (10.235.10.10) with Microsoft SMTP Server

It looks to me as if the message was sent out of my second server. This seems odd to me.
I have the Send connector setup on  Exc1 but I do also have a Send connector setup on Exc2. However, I no users on any database on Exc2.

So my questions:
1. Does Exchange arbitrarily use either server to send messages out?
2. If I disable the send connector on Exc2 will that affect mail delivery in any bad way?

The reason I'm concerned about mail going out of Exc2 is because I have a Reverse DNS PTR set up to point back to Exc1. If mail goes out of Exc2 then I'm concerned certain mail hosts won't accept the messages.

Thanks!

Check the connector for what? Can you be more specific as to what you think the problem may or may not be?

If possible can you paste the header information and connector design

Response was essentially correct but it was so terse that I had to look on other sites to understand what the poster was talking about. Also, poster never responded back to my last question about his response.
