Gmail to Fax - Google

Gmail to Fax

TPC Fax is a free service that lets you send text faxes by email. It doesn't
have a huge international coverage, but it works for most big cities.

To send a fax, you need to drop a mail to:
remote-printer.recipient_name@fax_number.iddd.tpc.int
where recipient_name is the name of the person or institution you're sending
the fax (use _ instead of space).

Adrian Hristov, who sent me this tip, has an interesting idea: what if you
forward all your mails from Gmail to a fax number using this service? You
could also use a filter to forward only some of the mails.
