I'm guessing that you either are trying to send from a company network that does not allow smtp usage, or you simply need to use tsl. And use the email library, it handles all the ugly stuff for you. Here's a function that does what you are trying to do. All the args are strings except port (int), tls (boolean) and files (list of file names of attachments). The code below is part of a larger program, so some of the imports may not be needed.
import os, time, sys
import smtplib
from socket import gaierror
from email.mime.text import MIMEText
from email.mime.base import MIMEBase
from email.mime.multipart import MIMEMultipart
from email.utils import COMMASPACE, formatdate
from email import Encoders
from mah.wxDialogs import ibox, getfiles, ibox
import utils
def sendMail(host, user, pwd, port, subject, tls,
sender, to, cc, files, text, pid='0'):
'''main email sending function'''
## print host, user, pwd, port, tls
msg = MIMEMultipart()
msg['From'] = strOrBust(sender)
msg['To'] = strOrBust(COMMASPACE.join(to))
if cc:
msg['Cc'] = strOrBust(COMMASPACE.join(cc))
msg['Date'] = strOrBust(formatdate(localtime=True))
msg['Subject'] = strOrBust(subject)
#encode body unicode to str before sending
msg.attach(MIMEText(strOrBust(text)))
for file in files:
#run with basic bag of bits, using mimetypes to try to figure out
#file type is not worth the effort, and is not as reliable
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)
try:
server = smtplib.SMTP(host, port)
except (smtplib.SMTPException, gaierror), error:
mailer.sb.SetStatusText('Failed to send email')
ibox(str(error) + ' Cannot connect to Server!','Failed!')
return
# Optional, but it gives you a nice view of the conversation
## server.set_debuglevel(1)
server.ehlo()
if tls:
server.starttls()
server.ehlo()
if user:
server.login(user, pwd)
#sendmail doesn't care about to and cc, so add them together
#then uniqify
toall = to + cc
toall = uniqify(toall)
try:
server.sendmail(sender, toall, msg.as_string())
if mailer:
mailer.sb.SetStatusText('Message ' + pid +
' was successfully sent')
except smtplib.SMTPException, error:
if mailer:
mailer.sb.SetStatusText('Failed to send email')
ibox(str(error),'Failed!')
server.close()
return
def strOrBust(obj, encoding='utf-8'):
'''converts unicode objects or other objects to str or returns original
encoded to enncoding'''
if isinstance(obj, basestring):
if not isinstance(obj, str):
obj = obj.encode(encoding, 'ignore')
else:
obj = obj.encode(encoding)
else:
obj = str(obj).encode(encoding)
return obj
def uniqify(seq):
''' Order preserving uniqifier for list, tuple or string'''
seen = set()
return [x for x in seq if x not in seen and not seen.add(x)]
good luckMike
