Missing Requestor Name from Email

Greetings Everyone,
We recently decommissioned our Exchange 2007 box ( I know I know…) and pointed all STMP Relay traffic at our Exchange 2010 box. Ever since that change we seem to have lost the name of the person opening the ticket.
The From in outlook used to show: Apache apache@rt.domain.com on behalf of John Smith john.smith@domain.commailto:john.smith@domain.com
Now it looks like: Apache apache@rt.domain.commailto:apache@rt.domain.com on behalf of RT Queue rt@rt.domain.commailto:rt@rt.domain.com

Email is routed like this:
John.smith@domain.com -> Exchange 2010 -> Ex2010 Send Connector to RT Box -> RT Box

Then from RT -> Exchange:
RT Box Sendmail 8 -> RT Box Postfix Relay -> Exchange 2010 -> John.smith@domain.com

I’ve played with the sendmail arguments, tried different send connector settings in Exchange, and modifying the External Recipient/Mail Contact that we use to facilitate the RT Mailbox; all to no avail…

Anyone have some ideas? Thanks in advanced!
Andy

And of course somehow overnight it decided to fix itself…awesome - wish I could outline what it could have been…
