Trying to use gmail smtp I get this error message:
A problem occurred while sending the email. Please revise your settings. (Error: Failed to authenticate on SMTP server with username "myemail@gmail.com" using 1 possible authenticators)
I then get an email from gmail saying - “Google just blocked someone from signing into your Google account myemail@gmail.com from an app that may put your account at risk.”
I can allow a less secure app but would prefer not to –
