Sending Mail Via Postfix: A perfect Python Example :)
Friday, January 1st, 2010I have been playing with Postfix for the last couple of days. I have already posted a perfect php class for sending email with attachments in a previous post. The Python example I posted earlier does the job for me but it was not perfect like the php one.
After digging a while, I found a nice way to do the same for python as well. I have just tested the codes and the result is perfectly what I desired 
Here’s the code:
import smtplib from email.MIMEMultipart import MIMEMultipart from email.MIMEBase import MIMEBase from email.MIMEText import MIMEText from email.Utils import COMMASPACE, formatdate from email import Encoders import os def sendMail(to, fro, subject, text, files=[],server="localhost"): assert type(to)==list assert type(files)==list msg = MIMEMultipart() msg['From'] = fro msg['To'] = COMMASPACE.join(to) msg['Date'] = formatdate(localtime=True) msg['Subject'] = subject msg.attach( MIMEText(text) ) 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() # Example: sendMail(['maSnun <masnun@gmail.com>'],'phpGeek <masnun@leevio.com>','Hello Python!','Heya buddy! Say hello to Python! :)',['masnun.py','masnun.php'])

This code (or the PHP version) isn’t exactly specific to postfix. All you need is a sendmail compatible mailer daemon installed in the system. All of the popular MTAs (postfix, exim, qmail etc) support the sendmail way of sending mail.
