John,
The fact that e-mail users must enter their fully-qualified address while
logging in takes care of the multiple-domains issue. On top of this, they
all should use SMTP AUTH for security reasons. Migrating from dedicated IP
domains to virtual domains should not be an issue as long as users log in
using their fully-qualified adresses, e.g. [EMAIL PROTECTED] and
[EMAIL PROTECTED]
In short, users *must* enter their fully-qualified addresses as their login
names *and* you should enforce SMTP AUTH for everyone.

> Account name: johndoe
> Password: mydogsname

> User "John Doe #2 at XYZ.com" Outlook settings:
> Email Address: [EMAIL PROTECTED]
> POP3: mail.XYZ.com (resolves to 123.123.123.1)
> SMTP: mail.XYZ.com (resolves to 123.123.123.1)
> Account name: johndoe
> Password: mybirthday
