[gentoo-dev] SPF at g.o

[Alin Nastac]

Facts:
    a) current SPF TXT record of our domain is "v=spf1 mx ptr ?all"
    b) I use my own MTA to send my @g.o messages.
    c) Probably I am not the only one who does that

I've just evaluated SPF support in spamassassin and I've discovered that
SPF_NEUTRAL has a big fat score of 1.1.
I don't know about you guys & gals, but I'm not used to have
spamassassin scores > 1 assigned to messages sent by me. Yes, I know, it
is only a statistical score, but if SPF_NEUTRAL has such a big
probability of being spam, that could only means it is used more by
spammers than honest folks. Btw, I don't think SPF's failure to become a
industry standard is a secret to anyone.

Conclusion:
  The proper TXT record for our domain would be "v=spf1 +all", which
translates (according to http://new.openspf.org/SPF_Record_Syntax ) as
"the domain owner thinks that SPF is useless". And it really is useless,
at the very least for our widespread organization.
