It’s what mail servers use to send and receive emails on the Internet.įor example, when you send an email, your email client needs a way to upload the email to the outgoing mail server.

Server.SMTP, short for Simple Mail Transfer Protocol, is the standard protocol for email transmission on the web. '''.format(to=receiver_email, sender=sender) # this is what changed, we use an alias instead Receiver_email = # this is to who we have sent the email Sender = # this is who we appear to be (i.e. If any email experts know of better ways to do this please comment/answer though! The following code is what I used: sender_email = # this is who we actually are I'm not sure if this should be done (since it's technicaly faking who you are) but it seems to work. This is a somewhat easy fix though, simply modify the 'From: ' line in the email body. This worked with the above code and sent the email! However, the from was still not my custom domain email address. So, I tried logging into my 'main' iCloud account. Just before I was going to ask this question, I solved it!Īfter reading this reddit post, I figured that all custom domain iCloud+ accounts are actually alias of some sort to the main iCloud account. So how can I use my custom domain address with Apple's iCloud+ service with Python's SMTP? Server.starttls(context=context) # Secure the connection This was taken from this question: SMTP_SSL SSLError: unknown protocol (_ssl.c:590) try: Only when I changed the last part to use TLS instead would it connect and give me an authentication error. However, this was still giving me a connection error. ndmail(sender_email, receiver_email, message) With smtplib.SMTP_SSL(smtp_server, port, context=context) as server: '''.format(to=receiver_email, sender=sender_email) Password = 'some,password' # app specific password from Apple ID settings Receiver_email = # Enter receiver address This led me to the following code: import smtplib, ssl Additionally, they want you to generate an 'app-specific password' for outside applications. I will always either get 'Mailbox does not exist' or 'Authentication failed'.įrom the Apple support pages it seems like you need to use SSL over port 587.

However, I can't get logged into the SMTP servers.

I would like to use Python's SMTP to send automated emails with a custom domain iCloud+ email address.
