+=item forward_emails
+
+Returns a hash of svcnums and corresponding email addresses
+for svc_acct services that can be used as source or dest
+for svc_forward services provisioned in this package.
+
+Accepts options I<svc_forward> OR I<svcnum> for a svc_forward
+service; if included, will ensure the current values of the
+specified service are included in the list, even if for some
+other reason they wouldn't be. If called as a class method
+with a specified service, returns only these current values.
+
+Caution: does not actually check if svc_forward services are
+available to be provisioned on this package.
