Generatet eMailaddresses from script
===

We have an enviornment were the `svn` credentials are linux usernames, consisting of one letter of the fristname and 5 letters of the lastname. however we have eMailaddresses of the form `firstname`.`lastname`@company.org. We have a way to tie the credential name to the eMailaddress with a script, however I do not know how to tell jenkins to use this skript upon detecting a check in from a new user.

Is there an easy way to run a script to generate a users emailaddress upon the creation of a new user? Alternatively calculating the eMailaddress each time the user is supposed to receive a mial would work too.
