Unconditional adjustment of free software infrastructure for very
questionable rules of proprietary product is a very bad idea.

Make this dropping optional: if devs are using gmail and really need
that filtering, they can opt-in. Left it opt-out for other devs.

Mail filtering is a minefield: too much spam is bad, loosing
even single important e-mail due to over restrictive filter is even
worse.

I've had enough with over restrictive mail servers, e.g. blocking
entire countries and ip ranges. I don't want to see Gentoo going
that way too.

Why so much focus on spamassassin? Why not to use (perhaps in
addition) more elegant technologies as the double grey listing?
