How to create a custom validator

Rails
1

i was wondering how can i create my own custom validates_ function. e.g.
i am validating email adresses on a lot of places and would like to
achieve the following

class User
validates_email :email
end

does some has any hints?

with the same technique i would also like to do the following

class User
strip_attributes :firstname, :lastname
end

this would automatically ensure that the attributes firstname and
lastname are stored always without preceeding and trailing spaces.
thanks for your help…
