Unity - VPIM, cannot deliver

I'm testing the VPIM communication with the 3rd party system(Callexpress) and have a delivery issue.

1. Unity and Callexpress both systems are on the same AD domain as name domain1.com

- create two DNS zones that domain1.com and yyyy.ca and register the A and MX record. unity into domain1.com and Callexpress to yyyy.ca

2. Unity(4.0.4sr1)

- primary location, dialID=1111, SMTP domain=domain1.com

- delivery location, dialID=2222, SMTP domain=yyyy.ca

- subscriber ext=5001

3. Exchange VC

- VPIM transport sink=domain1.com

- recipient policies=@domain1.com

4. Callexpress

- primary location, dialID=2222, SMTP domain=yyyy.ca

- delivery location, dialID=1111, SMTP domain=domain1.com

- subscriber ext=2002

5. if I send a message from Unity to callexpress, fails the delivery with showing the recipient as to:2222+5F2002@domain1.com

6. if I sending from callexpress, success the delivery with format from:2222+5F2002@domain1.com, to:test1@domain1.com

Q} why the Unity send the SMTP doamin format as domain1.com instead of yyyy.ca? or please advide to resolve the issue.

Thanks in advance,

Re: Unity - VPIM, cannot deliver

it was DNS name issue. copied the callexpress name from dynamically learned via the AD into yyyy.ca zone's A and MX record.

Re: Unity - VPIM, cannot deliver

my previous resolution was wrong. it was my mistake by coincidence. the problem was SMTP domain yyyy.ca in the exchange default policy. since remove it I can successfully able to sending from Unity to Callexpress.

- recipient policies=@domain1.com, @yyyy.ca

The SMTP domain described is the production environment. is there any way to send from Untiy to Callexpress with keep the yyyy.ca which Callexpress's local domain?
