dnl This is only an old example. Proceed with caution sendmail hackers...
dnl
dnl This is the sendmail macro config file. If you make changes to this file,
dnl you need the sendmail-cf rpm installed and then have to generate a
dnl new /etc/sendmail.cf by running the following command:
dnl
dnl        m4 /etc/mail/openisp.mc > /etc/openisp.cf
dnl
include(`/usr/share/sendmail-cf/m4/cf.m4')
VERSIONID(`openisp.net small-isp($Id: openisp.mc,v 1.2 2003/12/17 22:25:00 ggw Exp $) linux/RH7.3')dnl
dnl let's define our OS type. This one is mandatory.
OSTYPE(`linux')dnl
define(`confDEF_USER_ID',``8:12'')
dnl the following line moves the default alias file location to /etc/mail Doing it this way
dnl allows the newaliases command to function properly with the aliases file
dnl once it's moved from the Red Hat default location in /etc.
define(`ALIAS_FILE',`/etc/mail/aliases')dnl
dnl if the net were a kinder gentler place we wouldn't need the next line.
define(`confPRIVACY_FLAGS', `authwarnings,needmailhelo,noexpn,novrfy')dnl
dnl if it's not immediately deliverable let us know in 4 hours and return it if it's
dnl not been delivered after 4 days.
define(`confTO_QUEUERETURN', `4d')dnl
define(`confTO_QUEUEWARN', `4h')dnl
dnl Let's tell the system where procmail lives
define(`PROCMAIL_MAILER_PATH',`/usr/bin/procmail')dnl
dnl we don't need either one of the next two entries so lets remove the default.
undefine(`UUCP_RELAY')dnl
undefine(`BITNET_RELAY') dnl
dnl when people move on it will really help to give them an informative bounce
FEATURE(`redirect')dnl
dnl we are 'isp.net' after all. Let's make it so.
FEATURE(`always_add_domain')dnl
dnl let's set up class w as a text file. It's easier to manage that way. Since this host is
dnl designed to relay be careful about what you put in this file
FEATURE(`use_cw_file')dnl
dnl we defined the path to procmail now let's implement it
FEATURE(`local_procmail')dnl
dnl we won't be doing any uucp
dnl This has new options....figure out
dnl FEATURE(`nouucp')dnl
dnl with the mailertable we can redirect mail anywhere we want. Very handy. Particularly for an ISP.
FEATURE(`mailertable', `hash -o /etc/mail/mailertable')dnl
dnl with the virtusertable we can have multiple mail accounts with the same name
FEATURE(`virtusertable', `hash -o /etc/mail/virtusertable')dnl
dnl the access file gives us fine grained control of our relay capability
FEATURE(`access_db', `hash -o /etc/mail/access')dnl
dnl Uncomment below if you want dnsbl (slow recommend spamassassin with procmail w/razor and dcc)
dnl FEATURE(`blacklist_recipients')dnl
dnl note that we patched our version of sendmail to be able to use more than one rbl entry
dnl see section 2.3.2 of this document for more information and a HOWTO. These next 3
dnl entries are completely optional but recommended if you'd like to limit the amount
dnl of spam you receive inbound to your domain
dnl MAPS wants money! How dare they :)

dnl the default MDA with Red Hat Linux is procmail so let's use it. We need this line.
