Finally got the SPAMASSASSIN panel to show... Swert-Knudsen's site SH script seems to have commented out the SA panel's rpm, presumably for his own good reasons. However, as other rpms are pointing to his script and whose subsequent intelligence sort of needs the Blotwijk rpm to be installed, it leaves idiots like me running around in headless circles disappearing up my own singular event horizon;~/
Not forgetting another, seemingly necessary, tweak involving the AMAVIS-NG config file (needing an qmail entry to allow it run concurrently with SA... or something like that). I'm really not an expert in all this. I take photographs. Computers are needed throughout. And it's the latter bit that's where things always start to get messy for me.
Stuff is rolling - I think. 'Xpect the logs to be full to the brim with reconfig lines, errors, and gunk like that but hopefully I will now be able to educate myself on how all this (antivirus, spam trapping, TMDA) properly works in actual practise.
Many thanks to the contribs.org archive, its myriad human feeders, for all the pointers and URLs - g'night:-)
