using smtp in python

[ashikbekal at gmail.com]

I'm trying to send an email using python. The mail content is taken from file and subject of the mail is name of the file. The program is invoked as 
    ./mailclient.py -f <from email address> -d <recipient email address> -i <file1> -s <server IP address>
.
How to i use server ip address and the mail id to send the email ? (would i require the password)
