    Attachment Size and SMTP EMail

    Hello All -

    I am using python to send an email with a large zip file as an
    attachment. I successfully sent a 52M attachment. If I try to send a
    63M attachment or larger, the message never gets through. I do not
    get any errors in my python code. I pasted my python code below.

    from email.MIMEBase import MIMEBase
    from email.MIMEMulti part import MIMEMultipart
    from email import Encoders
    import smtplib,os

    mssg = MIMEMultipart()
    part = MIMEBase('appli cation',"octet-stream")
    part.set_payloa d(open(zipFileN ame,"rb").read( ))
    Encoders.encode _base64(part)
    part.add_header ('Content-Disposition', 'attachment; filename="%s"' %
    os.path.basenam e(zipFileName))
    mssg.attach(par t)

    s = smtplib.SMTP('l ocalhost')
    s.set_debugleve l(1)
    s.sendmail(from Addr,toAddr,mss g.as_string())
    s.quit()

    I am using a Fedora Core 6 system with python 2.4.4.

    Any suggestions on what could be limiting the attachment size or how I
    could troubleshoot this?

    Thanks!

      Does sending large attachements with other SMTP clients using
      the same SMTP server work?

          I do not know for sure. I recently downloaded msmtp 1.4.16 and am
          still in the process of trying to get it to work.
