restrict_post problem and question

["Fernando Donate" <fernando @ bitmailer . com>]

Hello list,

	Can I configure restrict_post directive with both listfiles and
domains? :
	restrict_post= listfile:@adomain

	Or Can I put @domains in a listfile? :
	restrict_post= listfile

	where listfile:
	pepe@pepe.com
	pepe2@pepe.com
	@adomain.com

	Thanks,	
		Fernando
