Sending e-mail through the internet is quite a trivial trick in many programming languages. Some time ago, I have shown how to send MS Excel range as an e-mail and how to send a mail through VBA, with HTML.
As far as now I am interested in Python, a few days ago I have developed a simple banking software system, as a respond of this task. One of the features of the bank system, was to send a password with a hashed code, if the original password was forgotten. Thus, I have registered a new account in Yahoo.Mail and I have started to spam myself in a way to learn how to do it. 🙂
After some research I found three things:
- There is a library called smtplib, which helps you a lot in the idea!
- If I am going to publish this in the internet, it is a great idea to import the username and the password from another folder. Thus, in my case, these are imported from settings.
- The mails are received about 2 to 3 minutes after they are sent, but this was time I was willing to wait.
At the end, I have received managed to receive something like this:
Well, that was my target, so I managed it! 🙂
At the end, as usual, here comes the self-explanatory code:

import smtplib from email.mime.text import MIMEText from settings import SMTP_USERNAME, SMTP_PASSWORD def send_mail(username, password, mail=SMTP_USERNAME): SMTP_SERVER = "smtp.mail.yahoo.com" SMTP_PORT = 587 EMAIL_FROM = SMTP_USERNAME EMAIL_TO = mail EMAIL_SUBJECT = "Test Mail - Password reset Money-In-The-Bank Project" co_msg = """ Disclaimer: Please, consider this mail just a test mail with educational purposes, if by any mistake you receive it. Simply delete it. I am sorry! :) Hello, {}! You have requested a password reset. Please, enter the following password for password: (between the ">>>" and the "<<<" signs below): >>>{}<<<. Have a great day! Best Regards, Money-In-The-Bank Training Team """.format(username, pas sword) msg = MIMEText(co_msg) msg['Subject'] = EMAIL_SUBJECT msg['From'] = EMAIL_FROM msg['To'] = EMAIL_TO debuglevel = True mail = smtplib.SMTP(SMTP_SERVER, SMTP_PORT) mail.set_debuglevel(debuglevel) mail.starttls() mail.login(SMTP_USERNAME, SMTP_PASSWORD) mail.sendmail(EMAIL_FROM, EMAIL_TO, msg.as_string()) print("A new mail has been generated and sent to {}.".format(EMAIL_TO)) mail.quit() send_mail(SMTP_USERNAME, SMTP_PASSWORD) |
A few notes on the code:
- You may decide to set “debuglevel” to “False”, in order to miss the 20 lines of interaction with the yahoo servers.
- In the current code, you are sending an e-mail to yourself. In my case jobanana500 is sending to jobanana500. I did this, with the idea not to spam someone by mistake. It is rather easy to find a way how to send a mail to someone else.
- Last but not least, do not forget that spamming is a crime!
That’s all folks! 🙂
