Wouldn't it be a lot easier to use the email module?

This is a snippet of how I send attachments (simply replace 
TO,FROM,Subect, path (full pathname including filename) and filename 
with relevant data):

import smtplib
import mimetypes
from email.Encoders import encode_base64
from email.MIMEAudio import MIMEAudio
from email.MIMEBase import MIMEBase
from email.MIMEImage import MIMEImage
from email.MIMEMultipart import MIMEMultipart
from email.MIMEText import MIMEText

def getAttachment(path, filename):
     ctype, encoding = mimetypes.guess_type(path)
     if ctype is None or encoding is not None:
         ctype = 'application/octet-stream'
     maintype, subtype = ctype.split('/', 1)
     fp = open(path, 'rb')
     if maintype == 'text':
         attach = MIMEText(fp.read(),_subtype=subtype)
     elif maintype == 'message':
         attach = email.message_from_file(fp)
     elif maintype == 'image':
         attach = MIMEImage(fp.read(),_subtype=subtype)
     elif maintype == 'audio':
         attach = MIMEAudio(fp.read(),_subtype=subtype)
     else:
         print maintype, subtype
         attach = MIMEBase(maintype, subtype)
         attach.set_payload(fp.read())
         encode_base64(attach)
     fp.close
     attach.add_header('Content-Disposition', 'attachment',
			filename=filename)
     return attach


msg = MIMEMultipart()
msg['From'] = FROM
msg['To'] = TO
msg['Subject'] = SUBJECT
attach = getAttachment(path, filename)
msg.attach(attach)

server = smtplib.SMTP(MAILSERVER)
server.sendmail(FROM, [TO], msg.as_string())
server.quit()
