import smtplib, sys, MimeWriter, StringIO, base64, os, time
 
    def mail(serverURL=None, sender='', to='', subject='', text=''):
  
 message = StringIO.StringIO()
 writer = MimeWriter.MimeWriter(message)
 writer.addheader('Subject', subject)
 writer.startmultipartbody('mixed')
  
 # start off with a text/plain part
 part = writer.nextpart()
 body = part.startbody('text/plain')
 body.write(text)
  
 # now add an attachment
 part = writer.nextpart()
 part.addheader('Content-Transfer-Encoding', 'base64')
 body = part.startbody('text/plain')
 base64.encode(open(filename, 'rb'), body)
  
 # finish off
 writer.lastpart()
  
 # send the mail
 smtp = smtplib.SMTP(serverURL)
 smtp.sendmail(sender, to, message.getvalue())
 smtp.quit()
