Sending Attachments as an E-mail using Python
To send an e-mail with mixed content requires to set Content-type header to multipart/mixed. Then, text and attachment sections can be specified within boundaries.
A boundary is started with two hyphens followed by a unique number, which cannot appear in the message part of the e-mail. A final boundary denoting the e-mail's final section must also end with two hyphens.
Attached files should be encoded with the pack("m") function to have base64 encoding before transmission.
Example
Following is the example, which sends a file /tmp/test.txt as an attachment. Try it once −
#!/usr/bin/python import smtplib import base64 filename = "/tmp/test.txt" # Read a file and encode it into base64 format fo = open(filename, "rb") filecontent = fo.read() encodedcontent = base64.b64encode(filecontent) # base64 sender = 'webmaster@tutorialpoint.com' reciever = 'amrood.admin@gmail.com' marker = "AUNIQUEMARKER" body =""" This is a test email to send an attachement. """ # Define the main headers. part1 = """From: From Person <me@fromdomain.net> To: To Person <amrood.admin@gmail.com> Subject: Sending Attachement MIME-Version: 1.0 Content-Type: multipart/mixed; boundary=%s --%s """ % (marker, marker) # Define the message action part2 = """Content-Type: text/plain Content-Transfer-Encoding:8bit %s --%s """ % (body,marker) # Define the attachment section part3 = """Content-Type: multipart/mixed; name=\"%s\" Content-Transfer-Encoding:base64 Content-Disposition: attachment; filename=%s %s --%s-- """ %(filename, filename, encodedcontent, marker) message = part1 + part2 + part3 try: smtpObj = smtplib.SMTP('localhost') smtpObj.sendmail(sender, reciever, message) print "Successfully sent email" except Exception: print "Error: unable to send email"
