Reply-Address isnt quite right

Hello All,

            I am having issues with the reply address set by RT. I have

a slightly less than perfect environment to work with and i need some
direction. My setup is as follows:

All of my systems are in Domain1.com domain. so for example, my exchange
server is Exchange-01.Domain1.com and my RT3 server is rt3.Domain1.com. My
exchange server only accepts mail for Doimain2.com, and NOT for Domain1.com.

So i have a mailbox in Exchange, Support@Domain2.com, that forwards all mail
to a contact that points to rtsupport@rt3.Domain1.com. The mail ends up at
the RT server, and a reply email is generated. However, when the reply email
is generated it comes to the creator as Support@Domain1.com instead of
ClientSupport@Domain2.com. I have even tried adding the
$CanonicalizeEmailAddress variables to replace rt3.Domain1.com (the
generated reply address) to have it be replaced by Domain2.com, but it just
doesnt seem to be working. I even have manually added
ClientSupport@Domain2.com for the reply and comment addresses in the queue
that i am working in !

Anyone have any ideas where i need to make a change for RT to send the
proper Queue-Based reply email address ?

Here is my RT_SiteConfig.pm file for the things that i am manually changing.

<<<<<<<< /etc/rt3/RT_SiteConfig.pm >>>>>>>>

Set( $rtname, ‘rt3.Domain1.com’);

Set( $WebPath , “/rt3”);

Set( $OwnerEmail , ‘blake@Domain2.com’);

Set( $FriendlyFromLineFormat , “Support”);

Set( $CanonicalizeEmailAddressMatch , ‘@rt3.Domain1.com’);

Set( $CanonicalizeEmailAddressReplace . ‘@Domain2.com’);

Set( $CorrespondAddress , ‘Support@Domain2.com’);

Set( $CommentAddress , ‘Support@Domain2.com’);

Any help/advise/direction that i can get will be a huge help. Thank you in
advance !
