Mail::Filter
provides an interface to filtering Email through multiple
subroutines.
Mail::Filter
filters mail by calling each filter subroutine in turn. Each
filter subroutine is called with two arguments, the first is the filter
object and the second is the mail or folder object being filtered.
The result from each filter sub is passed to the next filter as the mail
object. If a filter subroutine returns undef, then Mail::Filter
will abort
and return immediately.
The function returns the result from the last subroutine to operate on the mail object.
