Email alias

in CW 2 Site-Admins Helping Site-Admins

How can we change what roles or accounts are aliased with the generic timebank email account (i.e. timebank_name@timebanks.org) as used in automatic notifications such as account creation and guardian angel activity?  I see there is some alias operation that is done via cron but I don't see how to change anything about it.  None of the modules appear to address it and there don't appear to be any settings related to this.
