Sincerely, we are trying to apply the Minimum Necessary Change, and we have experience with sendmail in house, and it's the mailer used by the majority of institutes in our organization. Also we like the idea of rejecting spam. And our server is at the level of less than 1000 messages per day. >> QUESTION 0) is spamd necessary ? >No. The amavisd daemon behaves just like spamd and is used in its place. Thanks for the definitive answer. >> QUESTION 5) bayes autolearn and autowhitelist > >Bayes autolearn and autowhitelist work just fine with amavisd-new, >no matter how it interfaces with MTA. A global Bayes database is used >though - which can be a benefit or a drawback, depending on diversity >of your users. All similar (academic environment), and a global one is suggested by our super-arching academic and research network organization. The point is that it does not look to be working (the bayes file stays at size zero). We'll start debugging next week. >If you have a good set of rules (SA 3.1.2 and recent SARE rules) >and usual networks tests like DCC, Razor2 and RBL/URIBL enabled, >there is probably no need to pre-train bayes, just let it >autolearn for a couple of days of regular mail traffic, >perhaps with temporarily lowered scores for BAYES_* rules. I did sort of this when I was testing with spamassassin in procmail mode, but there I saw the file growing (and the header reporting it). >> QUESTION 3) Hits: - in syslog > >A '-' score means SA didn't produce any score. It normally means >SA was not called by amavisd because mail was too big Thanks again, THAT'S the answer, as proven by a sample inspection of the log. All '-' score are big messages indeed ! >Yes, using Petr Rehor's amavisd-milter is a must if you need dynamic >headers (like X-Spam*) to be inserted, or Subject to be edited (inserting >***SPAM***). I'd recommend it even if you don't. > >> 1) can one generate the detailed spamassassin report with milter ? >> 2) can one generate the X-Spam headers with milter ? > >Yes, with Petr Rehor's milter. I'll discuss it with our sysman next week (I'm just a sort of power user temporarily chairing our user committee). >> 4) can one replace the default X-Virus-Scanned by amavisd-new with >> a more detailed X-Spam-Virus-Scanned by amavis... on host xxxx ? > > $X_HEADER_TAG = 'X-Virus-Scanned'; > $X_HEADER_LINE= "$myproduct_name at $mydomain"; that's already in the amavis.conf, but we get only "X-Virus-Scanned by amavis". We edited $X_HEADER_TAG with no effect. Could it be they are not honoured with the default milter ? >> 6) can one customize the reject=550 5.7.1 Message content rejected >> with a longer and clearer message ? > >Not without modifying the program. I'll take note of this and discuss it. Thanks again for the clear definite answers ! I wish a nice weekend to you and all list members. ---------------------------------------------------------------------------- Lucio Chiappetti - INAF/IASF - via Bassini 15 - I-20133 Milano (Italy) For more info : http://www.iasf-milano.inaf.it/~lucio/personal.html ---------------------------------------------------------------------------- _______________________________________________ AMaViS-user mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/amavis-user AMaViS-FAQ:http://www.amavis.org/amavis-faq.php3 AMaViS-HowTos:http://www.amavis.org/howto/
