A: If you are using an LDAP directory. You should be able to resolve the email address for a user through an email property of the user in the LDAP. Don't know if that also works with Active Directory (but you should be able to access your AD with the LDAP protocol).

A: The Email-Ext Plugin is the most feature-rich facility for sending out email from Hudson.
For example, it can be configured to email the committer(s) who made changes since the last successful build.

A: Yes, Email-Ext Plugin, as mentioned is the most feature-rich email pluggin for Hudson.
You can enable an option to mail every commiter for success, failure and other...
I don't do any transformations on the e-mails though... I am configuring the profile of every user, where I update their e-mail address using their actual one.
