SMTP is for sending mail. IMAP/POP3 is for receiving mail.

As the doc string further says:

"If you do not have a certificate/key pair, leave the `key' and
`certificate' fields as `nil'.  A key/certificate pair is only needed if
you want to use X.509 client authenticated connections."

Therefore, you'd use something like this:

(setq smtpmail-starttls-credentials
      '(("smtp.inf.fh-bonn-rhein-sieg.de" 587 nil nil)))

(setq smtpmail-auth-credentials
      '(("smtp.inf.fh-bonn-rhein-seig.de" 587 "login" "password")))
