To make sendmail bind to selected interfaces use the following syntax
in /etc/mail/`hostname`.mc:
FEATURE(no_default_msa)dnl ## overridden with DAEMON_OPTIONS below
dnl
DAEMON_OPTIONS(`Name=3DIPv4, Addr=3D81.2.69.218, Family=3Dinet')dnl
DAEMON_OPTIONS(`Name=3DIPv4, Addr=3D127.0.0.1, Family=3Dinet')dnl
DAEMON_OPTIONS(`Name=3DMSA, Addr=3D81.2.69.218, Port=3D587, M=3DE')dnl
DAEMON_OPTIONS(`Name=3DMSA, Addr=3D127.0.0.1, Port=3D587, M=3DE')dnl
DAEMON_OPTIONS(`Name=3DIPv6, Addr=3D::1, Family=3Dinet6')dnl
DAEMON_OPTIONS(`Name=3DIPv6, Addr=3D2001:8b0:cf:1::1, Family=3Dinet6')d=
nl
dnl
This is taken directly from my own sendmail config, where I have a
jailed environment on 81.2.69.219 and I don't want the sendmail in the
host environment to listen on that IP number.
See the /usr/share/sendmail/cf/README file for more details
The 'DontProbeInterfaces' stuff is more commonly used when you have
either interfaces that only appear trasniently on the machine (such as
ppp connections) or you have interfaces with hostnames/IP numbers not
registered in the public DNS.
Cheers,
Matthew
