It's a good thing to try, but I'm not sure that many servers support this (yet)
And you're wrong, It doesn't hang, check your ps list:
{dns} root #1 23:54 [/etc]> ps auxxwwf | grep spfd
root 5104 0.0 0.0 5436 628 pts/3 S+ 23:55 0:00 | \_ grep spfd
root 4337 0.1 0.3 12868 6532 pts/5 S+ 23:53 0:00 \_ spfd listening at UNIX socket /tmp/spfd
But what to now - that I don't know
EDIT:But If this is the hoped result:
Code:
X-Spam-Status: No, score=-1.6 required=4.0 tests=AWL,BAYES_05,HTML_MESSAGE,
MIME_HTML_MOSTLY,RDNS_NONE,SPF_PASS autolearn=no version=3.2.0
Then: yes, it works, but you shoud start this command at startup, as a cron job or something like that, not from the shell
