Attempting to simplify my life, looked to ways to forward ham and spam to the spamassassin box and have it look a them, without further intervention on my part.
The link http://gtmp.org/pub/sa-postfix.en.html takes me to a page where there is nothing useful (AFAICT). The next link https://po2.uni-stuttgart.de/~rusjako/sal-wrapper/ takes me to a re-direct page, where I find the sal-wrapper.pl script and enough guidance to get me going. However, it does not deliver the mail I send it, returning a DSN. "<addressee>: Command died with status 9: "/usr/bin/sal-wrapper-0.2.1/sal-wrapper.pl". Command output: failed to create IP object at /usr/bin/sal-wrapper-0.2.1/sal-wrapper.pl line 129." I see similar in /var/log/mail. Using postfix as the MTA. There are some variables at the beginning of the script, that I suspect I need to define (local IP's for instance) which I did, in guess work fashion. I strongly suspect I do not have something configured correctly. I have attempted to contact the author, but thought I would also ask here, in case anyone has experience with it. Or wishes to offer advice.
