A spoofed email will just be ignored because it won't pass the checks!
What checks?
Said the spider to the fly.
Heh. I’m just curious, and the answer might affect my decision whether to use something like this, but you have a point.
The checks have changed significantly since we last spoke! Right now there are ~30 conditionals as it relates to determining if an e-mail is legit, and I imagine this will increase and be tweaked over time!
