Mail is configured on the Sidewinder G2 using the Reconfigure Mail tool. The
configuration process allows you to specify either transparent or secure split
(Sidewinder-hosted) mail services. If you select secure split services, you
specify a mail host on your internal network, and the necessary configuration
files are automatically sets up for you.
Once the Sidewinder G2 is configured, everything you need to run the mail
servers should already be set up:
• The three mail domains: mtac, mtaX, and mtaY (where X = the number of
the external burb, and Y = the number of an internal burb), are in place.
Sendmail is already configured to route mail among the three sendmail
servers.
• Mail addressed to users on your internal network will be forwarded to the
mail host you specified during configuration.
• Messages that are sent to the person administering a mail system are
generally addressed to “postmaster.” During configuration, you set up an
administrator’s account. Postmaster messages are automatically routed to
that user.
Note: You will need to configure your internal mail server to forward non-local mail
to the Sidewinder G2. This procedure differs depending on the type of mail program
your network runs. Refer to your mail software’s documentation for details.
To manually configure options for your mail servers, see “Managing sendmail”
on page 353.
To enable or disable the servers, see “Managing sendmail” on page 353.
To configure Application Defenses for mail services, see “Creating Mail
(Sendmail) Application Defenses” on page 172.
Viewing administrator mail messages on Sidewinder G2
Administrators can receive mail as soon as an account is created on the
Sidewinder G2. A mailbox will be created the first time an administrator sends
or receives a mail message. Mailboxes for Sidewinder G2 administrators are
stored in the /var/mail directory.
Important: Do not ignore the e-mail that accumulates on the Sidewinder G2 as it
contains important information about your network and Sidewinder G2 and also
uses disk space. Routinely read and delete mail sent to the Sidewinder G2, or have
it redirected elsewhere. To redirect mail to another destination, see “Redirecting
mail to a different destination” on page 364 or “Changing mail aliases” on page 369.
