Alert with more then one email address

[spin0]

My Alert setup is working fine with one email yyy@page.com.
I'm trying to send the alert to two emails, it seems not working.

I try to put in
TO: xxx@yahoo.com, yyyy@page.com
and
TO: xxx@yahoo.com; yyy@page.com

Any ideas?
Or the limitation is one email?

Thanks,

[ACM]

I believe it is limited to one email address
