SPF record

[Pavel Urban]

No, novinkou bych to zrovna nenazval ;-) Blizsi informace viz 
spf.pobox.com. Jde o pridavny zaznam do DNS, ktery rika, ze 'z techto 
adres muze prichazet posta, ktera se tvari, ze pochazi z teto domeny'. 
Microsoft se snazi prosadit neco velmi podobneho; rikaji tomu 'reseni 
problemu spamu' (marketing) nebo 'Caller ID'. Jak jsem se nedavno 
dozvedel, existuji jakesi tendence tyto aktivity spojit - viz 
http://www.microsoft.com/presspass/press/2004/may04/05-25SPFCallerIDPR.asp. 
Kazdopadne se to sice zatim moc nepouziva, ale spatna vec to neni. Ja 
bych tomu tech par minut venoval.
