(2006-02-03) Email comedy

I found this in my log over deleted spam:
"SPF","","","Välkommen till Microsoft Live 2006","Deleted","Sender is forged (SPF Fail)"

So what? Remember a few years ago when Microsoft was pushing for SPF (Sender Policy Framework)? SPF is meant to stop spam by verifying the return-path address. The theory is that you can use SPF to look up which mail servers that are allowed to send mail from a specific domain. If the return-path shows that the mail went through other, non-authorized servers, then it is considered spam. In order for SPF to be useful each domain must have a DNS-record that contains the authorized server.

Now, the logentry above shows that an email from was tossed away by my spam filter, because whatever mail server that sent it to me is not considered authorized to send me that mail. The subject is in Swedish and is legitimate (I happen to know this, as I expected the email) But still Microsoft’s "own" technology causes it to be treated as spam.

Yes Alanis, that's really ironic.
