Hi All,

I have configured my efax system, and I succeed to send fax using
email2fax feature using the internet but I need to secure the posting
process to my fax.

I'm using postfix and reached the point to secure submitting faxes to
my fax system, i tried to use -o sendfax command but it didn't effect.

Any idea????

# in the latter cases, quotes may or may not be used,
# there may or may not be any User Name at all, and User Name
# may come before or after user@xxxxxxxx.

# We need to make sure we handle all these possibilities for
