 If you are using two factor authentication, this will not work. In this case, you will need to create an /app password/. A guide on how to do this can be found [[https://support.google.com/accounts/answer/185833][here]]. From here, I can just replace this value with what used to be my normal password.
 
+** Installation for MacOS
+
+MacOS doesn't include a certificate file in the typical ~/etc/ssl/certs~ directory. Due to this, you have to create a file using the ~Keychain Access~ app.

+Open the Application Keychain Access.app
+Select System Roots in the sidebar
+Select all items listen here – ⌘ + a
+Export the items with ⇧ + ⌘ + e to the file ~/.mail/certificates/root-certificates.pem

 When running this however, you need to authenticate by creating an ~~/.authinfo~ file. This file is formatted as follows:
 #+begin_src text
-machine mail.example.org port 25 login myuser password mypassword
+machine smtp.gmail.com port 465 login myuser password mypassword
 #+end_src
 
 Similarly to the password configured above for the IMAP server, you can also pass an ~authinfo.gpg~ file for some added security.
