This is extremely minor, I am sure, but I believe it will require
slightly fewer CPU cycles, and function logically identically, if you
re-write that as:
condition = "${if or { {def:h_X-Spam-Flag:} {eq
{$received_protocol}{spam-scanned}}} {0}{1}}"
Note: "and" is replaced by "or," both logical nots ("!") are removed,
and the {0} and {1} are reversed. This is just the application of the
logical formula:
not(X) and not(Y) = not(X or Y).
I hope this is helpful.
