I have the following problem: I have email1, email2, email3 on domain A and email1 on domain B. On the server I have a virtual domain A. If I sent an mail intern from email1 to email3 in domaina.nl it is switched intern. But if I send a mail to email2@domaina.nl that isn't in the virtual domain, I get not able to deliver mail. How do I set the server to send it to outside if the recipient doesn't exist in local virtual domain?

In Companyweb on Win SBS 2k8 you are able to sent a mail with the URL from a file. But this opens in the local mail application. Is it possible to sent through OWA? (Companyweb > Shared Documents > Options > Send to...)
