I know that the `smtpmail-auth-credentials' variable has been removed in emacs 24.x, and that we are now expected to use an .authinfo file.
However, I have a specialized need for passing in SMTP credentials via elisp code, without any .authinfo file. I want to use "plain" user-ID/password authentication via port 587 with no SSL nor TLS.
Does anyone know how to accomplish this in 24.x with the credentials encoded in elisp and without the use of an .authinfo file?
Thank you very much in advance.
