sendmail configuration

Based on your earlier log messages and your latest errors

sendmail -v kalyan.sundu@<domain_name>.com<kalyan.sundu@%3Cdomain_name%3E.com>
<kalyan.sundu@%3Cdomain_name%3E.com>
<domain name>.com: Name server timeout
kalyan.sundu@<domain_name>.com <kalyan.sundu@%3Cdomain_name%3E.com>

You do realise that < and > are not valid DNS entries right ? (thats what
the %3C and %3E are in your log messages)

Generally <domainname> means "replace this with your domain" not litteraly
"put <domainname> here"

also, your domain name must resolve, i.e - if you type 'dig
mx.domainname.com' you must get some form of response. If you are getting
timeouts then you need to fix this first. (obviously, type the dig command
without the ' and ')

If you can't get DNS to work then switching to postfix is not going to help
you much (and postfix tends to want to ignore your /etc/hosts file as well
which makes it doubly important to get your DNS right)
