Re: [hylafax-users] Broadcast faxing

[Dimitry.Ketov@avalon.ru]

Ok I spent a little time to create (i suppose enough scalable) solution for
multicasting to fax numbers from file.
This patch adds new option -z <filename> to sendfax that equivalent to using
multiple -d <destination> at time, where nubers go from that file
<filename>.
Due to functionality of sendfax this way conserve MUCH space in
/var/spool/hylafax/docq by using only one copy of document for the first
number and hard LINKS to it for the next numbers. Futhermore, it can be used
with the (almost) infinite ;) quantity of phonenumbers.
All solution that uses scripts with the multiple -d <destinations> doesn't
scale well - on the HUGE quantity of numbers they give E2BIG error.

Dmitry.
