def sendMail(to, subject,text,files=[],server="127.0.0.1"):
        assert type(to)==list
        assert type(files)==list
        fro = "xx@x.com"

        debug_print("CWD -> " + os.getcwd())
        msg = MIMEMultipart()
        msg['From'] = fro
        msg['To'] = COMMASPACE.join(to)
        msg['Date'] = formatdate(localtime=True)
        msg['Subject'] = subject

        msg_body =  MIMEBase('text', "html")
        msg_body.set_payload(text1)


        msg.attach(msg_body)
        
        for file in files:
                part = MIMEBase('application', "octet-stream")
                part.set_payload( open(file,"rb").read() )
                Encoders.encode_base64(part)
                part.add_header('Content-Disposition', 'attachment; filename="%s"' % os.path.basename(file))
                msg.attach(part)

        smtp = smtplib.SMTP(server)
        smtp.sendmail(fro, to, msg.as_string() )
        smtp.close()

Why is that for msg_body of bigger size I see some junk characters like "! and ;" appear.
Is there any limitation on the size of the mail sent.
help please
