Sendmail

Configuring the Solaris-supplied version of Sendmail In this example, I will configure the version of Sendmail (8.11.7) that was installed by default on a Solaris 8 system. Sendmail will be configured to use header sender and envelope sender address masquerading and a "smart host."

On Solaris 9, substitute main.mc for main-v7sun.mc in the instructions.

1. Change to the directory containing the Sendmail configuration files.

cd /usr/lib/mail/cf

2. Make a copy of main-v7sun.mc as sendmail.mc, and make modifications to sendmail.mc.

cp main-v7sun.mc sendmail.mc

3. Configure sendmail.mc. In this example, we want to use the "smart host" smart_host.example.com and masquerade both the header sender and envelope sender addresses as example.com.

vi sendmail.mc

Insert the following entries before the MAILER lines:

define(`SMART_HOST', `smart_host.example.com')
MASQUERADE_AS(`example.com')
FEATURE(`masquerade_envelope')

4. Build the sendmail.cf file from the sendmail.mc file.

/usr/ccs/bin/m4 ../m4/cf.m4 sendmail.mc > sendmail.cf

5. Test the sendmail.cf file.

/usr/lib/sendmail -bt -C./sendmail.cf

Make sure that root is an "exposed user." An exposed user is a user that will not be masqueraded. This is used when accounts, such as root, are not unique across systems.

> $=E
root

Test header sender and envelope sender masquerading:

> /tryflags HS
> /try esmtp user@host.example.com
Rcode = 0, addr = user@example.com

> /tryflags ES
> /try esmtp user@host.example.com
Rcode = 0, addr = user@example.com

6. Backup the existing sendmail.cf file.

cp /etc/mail/sendmail.cf /etc/mail/sendmail.cf.date

7. Install the new sendmail.cf file.

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

8. Sendmail the Sendmail process a SIGHUP to begin using the new configuration file.

kill -HUP `head -1 /var/run/sendmail.pid`
