R7 - How to add Disclaimer only to certain outbound SMTP emails?

Right now, I am using a R7 server to append Disclaimer to ALL the outbound SMTP emails.I have created a Policy document with the following:

Policy Name: *

Policy Type: Organizational

These emails are NOT sent from Notes Clients.

But they are alerts generated by code.

I DO NOT want to append Disclaimer to ALL the emails.

I want to append only to those that are destined to certain domains.

For example: to all the emails that are going to @mycompany.com

Rest of the emails that are not going to @mycompany.com should not have Disclaimer appended.

Is this possible ?

Please advise.

Thanks in advance
