How to setup sendmail masquerade?

Solution

Open your sendmail config file /etc/mail/sendmail.mc (all examples are oracle.com):

# vi /etc/mail/sendmail.mc

Append/add/modify the lines as follows:

define('SMART_HOST','oracle')
  MASQUERADE_AS(oracle.com)dnl
  FEATURE(masquerade_envelope)dnl
  FEATURE(masquerade_entire_domain)dnl
  MASQUERADE_DOMAIN(oracle.com)dnl

Save and close the file.

# m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf
# m4 /etc/mail/sendmail.mc > /etc/mail/submit.cf

This Sendmail version requires you use the make command against the Makefile in /etc/mail/cf/cf

make

/etc/mail/cf/cf/sendmail.cf

Then perform this edit the sendmail.cf:

Find this section:
#####################
# Trusted users #
#####################

# this is equivalent to setting class "t"
Ft/etc/mail/trusted-users
Troot
Tdaemon
Tuucp
Tsmmsp <---------------------- Add this line

Save and close the file.

Copy sendmail.cf and submit.cf to /etc/mail

Add smmsp to /etc/mail/trusted-users

If this is what your sendmail services look like
# svcs -a |grep sendmail
online Mar_18 svc:/network/sendmail-client:default
online Mar_18 svc:/network/smtp:sendmail
# svcadm restart svc:/network/sendmail-client:default
# svcadm restart svc:/network/smtp:sendmail
