Not really... (you should me by know...I never do anything normally)
What we do is take a message address to a fax number
ie;[EMAIL PROTECTED] deliver it to a mail box that is
checked by one of our fax servers which then converts the body of
the message and any attchments into a fax formated tif. We then
send it to a fax out server that actually faxes the dovument to the
number embedded in the To: field. If there are 2 numbers in the to
field the fax is sent to both. but if the message is passed from the
qmail box as 2 separate messages we process the fax twice and
both reciepients get two copies of the fax. (and our customer get
billed twice)

Obtuse SMTPD only recieves mail, it_does_not attempt delivery!
Obtuse SMTPD only recieves mail, it_does_not attempt delivery!
Obtuse SMTPD only recieves mail, it_does_not attempt delivery!
I'll get this part yet. :-)
Is this (the relaying) handled by the smtpfwdd daemon in 4.1? Or is
it part of the qmail package?

P.I.T.A ? echew obfuscation. (DNA)

I did look at the header and did notice that for each message the
Delivered-To and Message ID were different. (this was on the
message received on the final destination sendmail box. The qmail
router only recieved the message once.
The way our fax servers work is to look at either the subject line or
the To: field for the fax number. (we based the parsing process on
sendmail) I'm pushing to convert all mailservers to e-smith boxes
running qmail (and obtuse-smtp on the newer systems). I'm just
looking to understand how the messages are processed so I can
take this to our developers, so they can modify the parsing
process.
