2 exchange domains in one server

Nope....exchange only supports on domain...you can use one exchange server to route multiple domains...but not to host two domains that I'm aware of and I've been teaching it for 2+ years...

It depends on what you mean by "domain". Exchange is usually organized by Organization and Site (for v5.5 and earlier) and by Forest and Trees for Exchange2000 so "Exchange domain" is an ambiguous term.

If you mean an Internet domain (e.g. companya.com and companyb.com), you just set up the SMTP routing on the Internet Mail Service (assuming you're using v5.5) and add the correct domain e-mail addresses to the SMTP address on each mailbox. It is recommended that you put each domain in a different container for administrative purposes.

If you mean an "NT" domain, there are a lot of variables and I would have to know more to answer your question.

Finally, if you're using "domain" when you mean Exchange Organization or Site, there are again some variables in how they are connected that might impact how you would proceed.
