There's two concepts here:

a) the driver (a module within Exim),
which has the lowercase word as it's label.

b) the ESMTP protocol word used to negociate use of the feature.
Traditionally in all-caps.


For this one there's maximum confusion. The driver only handles the one method.
But the "plaintext" driver (for instance) handles both LOGIN and PLAIN methods.
