I’ve long crusaded against the sometimes asinine, almost always problem-causing e-mail breaking measures taken by some; but I give up. The spammers have won.
Postfix and Localhost
October 22nd, 2007
Very useful additions to anyone’s master.cf:
smtpd_helo_required = yes
smtpd_delay_reject = no
disable_vrfy_command = yes
smtpd_helo_restrictions = permit_mynetworks, reject_invalid_hostname, reject_unknown_hostname, reject_non_fqdn_hostname
I’m an avid opponent of filtering based on ‘localhost’, as localhost is a perfectly cromulent name for a system. But I’m tired of you people, and your wee beedy eyes, and that smug look on your face. Ohhh, I’m going to buy your v1agr4, ohhhhhh.
Note: Still working out comments/etc. theming. Please ignore the ugliness.
