I've created my own testing environment for testing e-mail encryption
and such, where I have two Exchange servers simulating two different
companies. They have their own DNS that does not look to the root
hints, so I can pretty much enter any MX record I want.
Now, our Development people would like a similar setup so they can
test applications that send out Internet mail, without the mail
actually going out.
Not a problem. I can set up the same scenario for them and fake out
any MX record they'd like, and make a mailbox for it on the receiving
test Exchange server.
EXCEPT, we could be talking hundreds of domains and mailboxes here. So
what I'd really like to do is have some sort of router process or
server that sees all mail for companyA.com and routes it to a single
mailbox, all mail for companyB and routes it... and so on.
Or conversely, some sort of test server that will create a mailbox for
any unique incoming e-mail address.
I'm open to suggestions!!!
