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. 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.
