Delay in sending email to-from localhost in Sendmail

Hi Friends,

I am very much new to sendmail or any other mta. I just installed sendmail 8.14 on my rhel6 machine. I was trying to send email to local user but after entering the message when i press CTRL-D it simply hangs. I also tried sending email via mutt but again mutt also hangs. It sends the email but after taking a quite a long time like 2-3 minutes.

Here are the logs confirming that delay

Code:
Jun 22 21:03:07 test sendmail[2119]: q5N133lp002119: from=rohit, size=9, class=0, nrcpts=1, msgid=<201206230103.q5N133lp002119@test.home.com>, relay=root@localhost
Jun 22 21:05:55 test sm-mta[2120]: q5N137CR002120: from=<rohit@test.home.com>, size=263, class=0, nrcpts=1, msgid=<201206230103.q5N133lp002119@test.home.com>, proto=ESMTP, daemon=MTA, relay=localhost [127.0.0.1]
Jun 22 21:05:55 test sendmail[2119]: q5N133lp002119: to=stu, ctladdr=rohit (502/505), delay=00:02:52, xdelay=00:02:48, mailer=relay, pri=30009, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (q5N137CR002120 Message accepted for delivery)
Jun 22 21:05:55 test sm-mta[2220]: q5N137CR002120: to=<stu@test.home.com>, ctladdr=<rohit@test.home.com> (502/505), delay=00:00:00, xdelay=00:00:00, mailer=local, pri=30449, dsn=2.0.0, stat=Sent

So could any one suggest what could be the issue. IPTables is not running on the system.

Thanks in advance

NAME
mailstats - print statistics collected by sendmail SYNOPSIS
mailstats [-o] [-c ] [-C configfile] [-f statisticsfile] [-p] [-P] DESCRIPTION
The mailstats utility prints out the statistics collected by the sendmail(1M) program on mailer usage. These statistics are collected if the file indicated by the StatusFile configuration option of sendmail (defined in /etc/mail/sendmail.cf) exists. The default statistics file is /etc/mail/statistics. To enable mailstats, you must, as root, touch /etc/mail/statistics. See the StatusFile processing option in sendmail(1M). mailstats first prints the time that the statistics file was created and the last time it was modified. Then, the statistics for each mailer are displayed on a single line, each with the following whitespace-separated fields: M The mailer number. msgsfr Number of messages from the mailer. bytes_from Kbytes from the mailer. msgsto Number of messages to the mailer. bytes_to Kbytes to the mailer. msgsrej Number of messages rejected by the mailer. msgsdis Number of messages discarded by the mailer. msgsqur Number of messages quarantined by the mailer. Mailer The name of the mailer. The display of statistics described above is followed by a separation line containing only equal sign (=) characters. After the separation line, a line preceded with a "T" and totaling the values for all of the mailers is displayed. This is followed by another line preceded with a "C" that lists the number of TCP connections. To reinitialize the statistics file once a night, add an entry to root's crontab(1): mailstats -p > /dev/null OPTIONS
The following options are supported: -c Try to use submit.cf instead of the default sendmail configuration file. -C configfile Specify a sendmail configuration file. -f statisticsfile Specify a sendmail statistics file. -o Do not display the name of the mailer in the output. -p Output information in program-readable mode and clear statistics. -P Output information in program-readable mode without clearing statistics. USAGE
See largefile(5) for the description of the behavior of mailstats when encountering files greater than or equal to 2 Gbyte ( 2^31 bytes). FILES
/dev/null Zero-lined file /etc/mail/statistics Default sendmail statistics file /etc/mail/sendmail.cf Default sendmail configuration file ATTRIBUTES
