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

29 Make this dropping optional: if devs are using gmail and really need
30 that filtering, they can opt-in. Left it opt-out for other devs.
31
32 Mail filtering is a minefield: too much spam is bad, loosing
33 even single important e-mail due to over restrictive filter is even
34 worse.
35
36 I've had enough with over restrictive mail servers, e.g. blocking
37 entire countries and ip ranges. I don't want to see Gentoo going
38 that way too.

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