So here (forwarded below) is a more useful review of the public information.AUTH_EXTERNAL is already disabled in the port. I think we can disable AUTH_SPA by default in the port without too much trouble. It is disabled by default upstream. Renaud, do you have a handle on whether spf lookups are commonly used by Exim users? (With other MTAs this would typically be something done by separate anti-spam software rather than inside the MTA). This is also disabled by default upstream.
I think that is quite common to use spf lookups. At least, I did use them and know some installations using them. Exim is very flexible, so this is probably used by people to influence some other rules.
