A greener light for "junk" faxes. The House has voted to relax regulations on unsolicited commercial faxes. The bill would overturn FCC rules requiring senders of commercial faxes to get prior written approval from recipients. The rules, which were set to take effect last August, have been delayed until January. The House bill would rewrite the rules so that senders of commercial faxes would be required to prominently include "opt-out" instructions for recipients who no longer wish to receive them.
