sendmail relaying

[Robert Dege]

Should sendmail be spitting out some logs even if I get a relaying denied
message on the mail client?  I'm not getting any to help me troubleshoot
the problem.


/etc/mail/sendmail.mc

=====================

divert(-1)
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/mail/sendmail.cf by running the following command:
dnl
dnl        m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf
dnl
include(`/usr/share/sendmail-cf/m4/cf.m4')
VERSIONID(`linux setup for Red Hat Linux')dnl
OSTYPE(`linux')
dnl Uncomment and edit the following line if your mail needs to be sent
out
dnl through an external mail server:
dnl define(`SMART_HOST',`smtp.your.provider')
define(`confDEF_USER_ID',``8:12'')dnl

dnl This changes sendmail to only listen on the loopback device 127.0.0.1
dnl and not on any other network devices. Comment this out if you want
dnl to accept email over the network.
DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')
dnl NOTE: binding both IPv4 and IPv6 daemon to the same port requires
dnl       a kernel patch
dnl DAEMON_OPTIONS(`port=smtp,Addr=::1, Name=MTA-v6, Family=inet6')
dnl We strongly recommend to comment this one out if you want to protect
dnl yourself from spam. However, the laptop and users on computers that do
dnl not have 24x7 DNS do need this.
