Boredom has led me to implement SPF__ on my mailserver, using `this script`__.
Seems to be working happily::
action=PREPEND Received-SPF: pass (niamhe.bmalee.eu: domain of bma@bmalee.eu designates 82.45.24.36 as permitted sender)
Or, with a fake IP (simulating someone forging an address at bmalee.eu without
sending the mail from a permitted system)::
action=REJECT Please see http://www.openspf.org/why.html?sender=bma%40bmalee.eu&ip=82.45.24.33&receiver=niamhe.bmalee.eu
I’ll set it up on Zaphod__ at some point.
