Long data not being sent with smtplib.SMTP.sendmail?

[John Wiegley]

I have a 100K e-mail message that I'm sending over smtplib.SMTP (using
MimeWriter to build the message).  Although I've confirmed that the
'msg' argument I'm passing to sendmail is correct, smptlib fails to
send the last 20 or so bytes.  I've look at SMTP.send, but has anybody
else had problems with this?

Thanks,
