6.2.2 Mail Server
In many cases, the DNS server configuration explained in Section 1 is all you need to use the
email-to-FAX relay service. However, some mail servers are configured to process all mail
addressed to hosts belonging to their domain as mail to themselves. If mail server
mail.abc.com has been set up in this way, it will regard mail to xxxx@fax.abc.com as mail to
one of its users and will not forward it to the OKIFAX5950. To prevent this, it is necessary to
configure the mail server so that it will not process mail addressed host fax.abc.com.
The following explanation is based on an example where the OS of mail.abc.com is FreeBSD
and its mail server is sendmail. Configuration file sendmail.cf is generated using utility "CF".
Where no utility of this kind is available, you will have to edit sendmail.cf directly; as the proce-
dure for this operation is very complicated, it will not be explained here.
Insert the following strings to file sendmail.def.
............
ACCEPT_LOWER=yes
............
LOWER_MATCH_STYLE=!lw-file
............
Add to /etc/sendmail.lw a string specifying email-to-FAX relay.
............
fax
Create sendmail.cf and overwrite the original sendmail.cf with it. Now restart the mail server.
After the above changes, sendmail will forward mail addressed to xxxx@fax.abc.com to
OKIFAX5950 instead of processing it itself.
