Is it possible to use wildcard for multiple subdomains?

We have two seprate SMTP relays
One fr standard Emails traffice, the other for specifc adressed SMTP traffic
- evering that is adressed to .com should be routed to adress xxx.xxx.xxx.70
- everingthing that is adressed to sec.*.com should be routed trough to xxx.xxx.xxx.230

For some reason the route.cfg does not work using wildcard like the following sample

sample route.cfg
sec.*.com [xxx.xxx.xxx.230]
*.com [xxx.xxx.xxx.70]

Only the following entry works and is routed via adress xxx.xxx.xxx.230
sample of route.cfg which works:
sec.novell.com [xxx.xxx.xxx.230]
