Murthy,

There is another solution to this - it's been discussed recently on this
mailing list.

For the DNS issue, first decide whether you need a full local DNS at all.
Maybe you just need to configure the hosts file to include your local
machines.

If you do run DNS then set up a full DNS configuration according to the
article in Linux Gazette or the "DNS and BIND" book.

Configure sendmail so that the SMTP mailer is defined as "expensive".  That
causes sendmail not to send mail immediately but to wait for the next
connection.  You can find references to this on the Web and a package that
does the config is available via the freshmeat web site.

Test your sendmail configuration using sendmail -bv username for every local
user.  It should report the users as local and not cause a DNS lookup.  If
not, you have a configuration error.
