subdomain delegation for email routing

I have a client (company1.com) who has customers send email to several
special email accounts (such as customer service which goes to
care at company1.com). These emails are processed along with all other
corporate email by the corporate mail server and then forwarded to an
outside vendor (webservice.com) that handles these special email accounts.
A backup copy is made and kept by company1.com and the original is
forwarded to the vendor (e.g., to company1-cs at webvendor.com) and the vendor
responds to the email. Unfortunately average response times are 48 hours.
My client wants to have the customer service email delivered directly to
the outside vendor and I suggested that they create a subdomain
care.company1.com and delegate this subdomain to the vendor:
care.company1.com IN NS ns.webservice.com
care.company1.com IN MX mail.webservice.com
The vendor can forward email from care.company1.com to the appropriate end
user and then forward a backup copy to company1 (e.g., backup.company1.com)
.
Is this possible?
What DNS config is required?
Are there any pitfalls/better ways?
Thanks,
Alan
