RMS Weighs In On SPF/Sender-ID License
Stallman's message continues: "The Microsoft license for Sender-ID directly forbids release of software with all these freedoms, so it is impossible for any program to be free software under Microsoft's regime. I've been expecting to see something like this ever since Gates started talking about spam. This license is an example of Microsoft's strategy for killing off free software as an alternative to Windows. Microsoft first patents something, then incorporates it into a format or protocol, then tries to make it de rigueur while excluding those it wishes to exclude. In the absence of resistance, Microsoft has a good chance of imposing whatever standards it likes. Let us, therefore, resist it here and now."
Dude, you should have used SPF - Sperm Protection Filter. Did you bother to check the hooker's Sender-ID?
Put some Jam (Strawberry or Raspberry works best) on your "Head". When the likkle critters come to feed, blow them away with a shotgun.
HTH
This is RMS we're talking about. The guy that doesn't believe there should be a root user because every user should be "free" to demolish everyone else's boxen. The same guy who doesn't believe in password protecting FTP servers. If we limit anything it won't be "free."
I agree that block ALL port 25 traffic on your mail server from Windows computers is a good thing.
Or even configuring the mail to bounce back with a helpful message such as "Please upgrade to a secure operating system if you wish to send email to this domain."
