Such a trigger would violate one of Cobb's basic data normalization laws: a
field should not be dependant upon another field. if you have the domain
and the user, you can calculate the email address on an as needed basis. If
you want to use it on a form or a report, use a view along the lines of:

    SELECT FName, LName, User - '@' - Domain AS Email, [...]

[Instead of spending another 12 hours on this, spend the time searching at:

    http://fox.wikis.com/wc.dll?Wiki~DataNormalization~SoftwareEng

and the assorted links. A solid data structure is critical to your
application.
