23 Or so it should be. As I've written earlier, some very misguided
24 people not only judge the Envelope-From (i.e. "MAIL FROM" in
25 SMTP-Speak, which usually is identical to the header
26 "Return-Path") against SPF, but also the in-mail header From:.
27
28 Yes, it's downright stupid because it breaks just about nay
29 mailing software I know. Yes, it's used by at least two larger
30 providers in Europe. No, tech support there soesn't think it's a
31 bad idea after I explained it in easy, friendly words.
32
33 Idiots.
34
35 Still: there are two things to keep in mind:
36
37 1) Do you "just don't care" about the users of those ISPs.
38 2) Does Gentoo as a distro want to "advocate" for the usage of
39 SPF (ever so slightly) with the knowledge that it breaks
40 several things?
41
42 Regards,
43 Tobias
44
45 PS: Even without those idiots, SPF breaks pre-delivery forwards.
46 But also said that already and it was illustrated why that
47 happens on the "why SPF isn't quite ideal" page someone mentioned
48 earlier in the thread.

50 PPS: Windmills, anyone?
