I recommend that you use the standard packages email and smtplib together to send Email. Please look at the following example (reproduced from the Python documentation). Notice that if you follow this approach, the "simple" task is indeed simple, and the more complex tasks (like attaching binary objects or sending plain/HTML multipart messages) are accomplished very rapidly.
Here are a few examples of how to use the email package to read, write, and send simple email messages, as well as more complex MIME messages.
First, let’s see how to create and send a simple text message:
# Import smtplib for the actual sending function import smtplib # Import the email modules we'll need from email.mime.text import MIMEText # Open a plain text file for reading. For this example, assume that # the text file contains only ASCII characters. fp = open(textfile, 'rb') # Create a text/plain message msg = MIMEText(fp.read()) fp.close() # me == the sender's email address # you == the recipient's email address msg['Subject'] = 'The contents of %s' % textfile msg['From'] = me msg['To'] = you # Send the message via our own SMTP server, but don't include the # envelope header. s = smtplib.SMTP('localhost') s.sendmail(me, [you], msg.as_string()) s.quit()
For sending email to multiple destinations, you can also follow the example in the Python documentation:
# Import smtplib for the actual sending function import smtplib # Here are the email package modules we'll need from email.mime.image import MIMEImage from email.mime.multipart import MIMEMultipart COMMASPACE = ', ' # Create the container (outer) email message. msg = MIMEMultipart() msg['Subject'] = 'Our family reunion' # me == the sender's email address # family = the list of all recipients' email addresses msg['From'] = me msg['To'] = COMMASPACE.join(family) msg.preamble = 'Our family reunion' # Assume we know that the image files are all in PNG format for file in pngfiles: # Open the files in binary mode. Let the MIMEImage class automatically # guess the specific image type. fp = open(file, 'rb') img = MIMEImage(fp.read()) fp.close() msg.attach(img) # Send the email via our own SMTP server. s = smtplib.SMTP('localhost') s.sendmail(me, family, msg.as_string()) s.quit()
As you can see, the header To in the MIMEText object must be a string consisting of email addresses separated by commas. On the other hand, the second argument to the sendmail function must be a list of strings (each string is an email address).
the "","".join(to) part makes a single string out of the list, separated by commas.
From your questions I gather that you have not gone through the Python tutorial - it is a MUST if you want to get anywhere in Python - the documentation is mostly excellent for the standard library.
