I have a " font size=+0" & "font size=1" sample, and from what I can
tell in the report, this rule is not being hit. But I thought there were
some "small font" rules included. Hence ( at least in part) my question.
Being fairly new to SA, does it go through "each and every" rule and
test listed , on each email?
Short of SA crashing, yes. All tests that are enabled are run, every time. No
bailouts.
There's been some proposals to add the optional ability for a black or
whitelisted message to bail out of the tests early, but AFAIK that's not been
done yet, and even if it is it would be a "post 3.1.0" feature, possibly 3.2.0.
And before you or someone asks, as someone always does, no SA can't bail out as
soon as it hits the spam tag threshold. SA supported that feature a LONG time
ago (SA 2.20?) and it caused FPs because it bailed out before the
negative-scoring rules ran.
Forcing the negative-scoring rules to run first causes SA to have to scan the
whole body twice, (once for the negatives, then once for the positives) which
nullifies the speed benefits. If SA did a pass-per-rule you could sort the
passes and speed it up, but AFAIK SA does the body rules in parallel.
However, bailing out on a white/blacklist doesn't suffer from risk of FP/FNs..
you can work out the black/whitelists during the header pass and decide to bail
before the body scan. The body rules are unlikely to overwhelm the
black/whitelist, and if you are relying on that behavior you can always not use
the bail-out.
