Use email package. Something like the following (untested):

from email.MIMEText import MIMEText
msg = MIMEText(body)
msg['Subject'] = ...
msg['From'] = ...
msg['To'] = ...

from email.MIMEBase import MIMEBase
attachment = MIMEBase('application', 'octet-stream')
attachment.set_payload(open(filename, 'rb').read())
attachment.add_header('Content-Disposition', 'attachment', 
                      filename=filename)
from email.Encoders import encode_base64
encode_base64(attachment)
msg.attach(attachment)

# using popen is unsafe if we can't trust fromaddr, using subprocess
from subprocess import Popen, PIPE
mailfl = Popen(['/usr/bin/nullmailer-inject',  '-f', fromaddr],
               stdin=PIPE)
mailfl.stdin.write(msg.as_string())
mailfl.stdin.close()
mailfl.wait()
