unable to send/reply to mails in mutt

[svzard]

Hi all,
I just started using mutt. I just went through some articles and set my .fetchmailrc as

poll pop.gmail.com with proto POP3 and options no dns
user "svzard@gmail.com" is "svzard" here options ssl

and set my ~/.muttrc as

# My email address
set pop_user="svzard@gmail.com"
# To ensure mutt doesnot put 'username@localhost.localdomain in From:
set from="svzard@gmail.com"
set use_from="yes"
set envelope_from="yes"
# The test editor I want to use to write emails (the default is nano)
set editor=vi

As you can see, its pretty simple stuff. Just copied what I could make out from other's .muttrc file on the net and put my ids.

I'm able to read mails by running

$ fetchmail -vk
$ mutt

in that order.

But I'm not able to send or reply to mails using mutt. Only webmails can be downloaded.

What is missing here. I read the manual but could not grasp anything useful. Can you help me with the settings?

Btw, mutt -v on my system gives:

Well, I even added set sendmail="/usr/sbin/sendmail -oem -oi" to .muttrc. No help still.
