Gmail SMTP Settings for the Brother MFC-L3770CDW

TL,DR: Your SMTP settings should look like this:

---

If your Gmail account is 2FA protected - and it absolutely should be - you'll have to generate an app password.

You'll also need to configure at least 1 administrator email address in the web UI at Network -> Notification -> Administrator Address. Click 1 of the Notification links to set the address.

Going field by field:

• Server Address: smtp.gmail.com
• Port: 25 (Don't worry about the fact that Gmail's official SMTP documentation specifies ports 465 & 587 for SSL and TLS, respectively. Those apparently don't apply here)
• Server Authentication Method: SMTP-AUTH
• SMTP-AUTH Account Name: [e-mail]_Address
• SMTP-AUTH Account Password: app_password
• SSL/TLS: TLS
• Check Verify Server Certificate
• Device Email Address: Anything_You_Want (that doesn't have a space character, presumably)

After entering all the above, click Submit and then test the configuration in the following page. You should receive an email at the administrator address you previously configured.

I got:

Send E-mail Configuration
Verification of the server certificate was unsuccessful. To correct this, either import the appropriate CA certificate or uncheck the "Verify Server Certificate" setting (if verification is not necessary).

Did you generate the app password as described in the 1st sentence? That should take care of the certificate issue. If not, you may have to import a certificate at Network -> Notification -> SMTP>> -> CA Certificate>> -> Import CA Certificate>>.

Which model and firmware version are you using? I'm on Main Version ZA, Sub1 Version 1.60. However I did set up the email alerts on an earlier firmware version, so I'm not sure if things have changed since.

I tried the configuration and I get:
535-5.7.8 Username and Password not accepted
And I am pretty sure I am writing the credentials correctly. Googling a bit I found out that you have to configure “Less Secure Apps” in the gmail account but that option has been rolled out recently.
Any tips?

Make sure you do what I wrote in the 1st sentence. Otherwise the rest of the instructions will not work.
