If libmilter/MTA doesn't support quarantining, then you
want to detect that as early as possible. If you can
figure it out during "configure", then those quarantine
options should not be available for the config file.

If you can determine this only at runtime, then you have a problem:
what do you want to do in this case? How do you want to "fail"?
The most flexible way of course would be a "sequential" option


where OTHER is used if quarantine is not supported (OTHER:
tempfail, reject, ...)
That seems like overkill, but I don't know a good way to
deal with this.

I don't understand this part, sorry. The (global) "Quarantine"
option has a different purpose then those for On-*, right?
