Re: How long does it take to install SA?
Single-user, vanilla install with two exceptions: the install will check our two whitelists and give a pass (-100) to any of our clients so we don't bounce their mail. I hope you're not actually considering bouncing spam. That statement sounds like it. Either jecect them at smtp time or silently delete other then that. whitelist sounds very simple to me: http://wiki.apache.org/spamassassin/ManualWhitelist unless you want to query a database of couse. i'm using a check in my exim router to let some customers' customers bypass SA completly.

Re: How long does it take to install SA?
LuKreme, I've thought about going with amavis (mostly for spam rejection, I don't run VirusOS computers) but my problem has been that it seems that either amavis runs and rejects spam (in which case I need to set the threshold high) OR spamassasin runs and tags spam (in which case I can leave the threshold at 5.0). amavisd can do either, depends on how you configure it. What I want is all 5.0+ mail to be tagged and rendered safe (report_safe 1) and then all 10+ scoring spam to be rejected at the transaction phase. Is this possible with Amavis? $sa_tag2_level_deflt = 5; # add 'spam' headers at that level $sa_kill_level_deflt = 10; # triggers spam evasive actions Usually amavisd is placed as a post-queue filter, where it is too late to reject mail. On a small site with not a lot of mail traffic it may be possible (i.e. it happens to work, but does not meet all Postfix requirements for a transparent proxy) to use it as a pre-queue (Postfix proxy) filter, in which case it can do what you want - additionally you need: $final_spam_destiny=D_REJECT in such a setup (this setting must not be used in a post-queue setup!) Of course, the real problem is that I can't do per-user Bayes on the messages in the SMTP transaction phase, Indeed, per-user Bayes is currently not possible when SpamAssassin is called from amavisd. For a user population which is not very large and diverse, I'd claim that a global Bayes performs just as good, and possibly better: all users benefit from little training. so is it also possible to check them after the fact for bayes, or does that just mean rerunning all of SA's tests? It would require re-running SA tests. I wouldn't bother. Mark

Yeah, I tried global bayes, it failed miserably on my server with my users. -- *** AgentSmith sets mode: +m

Installing SA itself should take about an hour if you've never done it before. Most of that will be reading the INSTALL file :-) Once you've done it before, installing SA itself is only 2-3 minutes. Hooking it to postfix could take a few minutes, could take an hour or two. Methods like this one: http://wiki.apache.org/spamassassin/IntegratedSpamdInPostfix Boil down to reading the docs, and doing some copy-paste into configs.. goes pretty fast. Some other methods offer more efficiency, power and flexibility, but take longer to set up: http://wiki.apache.org/spamassassin/IntegratePostfixViaSpampd http://wiki.apache.org/spamassassin/IntegratedInPostfixWithAmavis (warning: the local.cf example contains outdated options.. and everything it specifies is the default... so it's a little silly, skip that part) Personally I'd go with amavis if you want to integrate antivirus, or do SMTP-layer rejections (ie: issue a 5xx error when the score is too high) Go with the first method if you want something quick and easy that just sticks a subject tag onto spam.
