Sendmail 8.11.1 Release Notes

DaemonPortOptions has one sub-option called ‘modifiers’ (M), one of which is
‘a’. This instructs the daemon to necessitate authentication for all connections to
it.
By default, it appears in the sendmail.cf file as:
#O DefaultAuthInfo=/etc/mail/default-auth-info
The DefaultAuthInfo option sets the filename which contains the authentication
information for outgoing connections by default. It must contain the authorization
id (userid), the authentication id (authid), the password (plain text), and the realm
to use, each on a separate line. This information must be readable only by root (or
the trusted user). If no realm is specified, $j will be used.
Virtual Hosting
This version of Sendmail imposes better control over virtusertable, which provides
a domain-specific form of aliasing and also allows multiple domains to be hosted
on a single machine.
With this feature, users can have their own domain names and receive mails using
these domain names with a single host. You are required to obtain a new (available)
domain name and set up name servers for that domain. Then, you must configure
MX records for your new domain.
NOTE: You must know how to setup DNS before implementing this feature. For
information on setting up DNS, refer to “Installing and Administering Internet
Services” manual, posted on http://docs.hp.com.
The following steps describe how to set up virtual hosting:
1. Assume mydomain.com as the new domain name. If the mail server which
serves the new domain name has a full time connection to the internet, include
the following line in the db.domain file.
mydomain.com. IN MX 10 mymailserver.mydomain.com.
Otherwise, you will need to have another machine to queue mails for your
domain. Include the following lines in the db.domain file:
mydomain.com. IN MX 10
mymailserver.mydomain.com.mydomain.com. IN MX 20
othermailserver.otherdomain.com.
Now, you must setup Sendmail.
