smtp text message code not sending

I have a python code to send a text message to your cellphone using SMTP. when I run it I don't get any errors, but it doesn't send the text message. My code isn't finished, right now I am just getting the basics down. Any help on making it send would be appreciated.

#infile = open('companyname.txt', 'r')

    while again != 'y' and again != 'n':
        print ('sorry that is an invalid answer!')
        again = raw_input('Do you want to ask again?')
    print



#old code:

#addr_from = raw_input ('enter your email address')
#addr_to = text_adr
#SMTP = 'smtp.comcast.net'
#msg = ('From: %s\r\nTo: %s\r\n\r\n'
#% (addr_from, ', '.join(addr_to)))
#msg = msg + 'This is the message'
#SMTP.sendmail(addr_from, addr_to, msg)

Start with the basics, enable debugging for the smtp object and see what you get.

smtpObj = smtplib.SMTP('smtp.comcast.net')         
smtpObj.set_debuglevel(10)
smtpObj.sendmail(sender,reciever , message)

You can read about the set_debuglevel call here.

Change

smtpObj.sendmail(sender,reciever , message)

to

smtpObj.sendmail(sender,[reciever] , message)

since the second argument to sendmail should be a list of email addresses.

PS: You might want to change reciever to receiver too... :)
