is rumored to have said:
trying to configure postfix and spamassassin on bookworm. sorting
through many conflicting recipies on the net of a million lies. one
has spamassassin as a milter, another as a `-o content_filter`, and
most are old, ubuntu, ... i got lost at twenty browser tabs.
Maybe you're looking too specifically, there's not much special about
Debian so there's not going to be a definitive Debian-specific document.
Or maybe that's just how integration goes with multi-platform FOSS
tools.
Yes, there are about a half-dozen 'glue' choices, each of which has its
own advantages and disadvantages and partisans. MIMEDefang, MailMunge,
Amavis as a Milter, Amavis as a SMTP proxy, spamass-milter, or a wrapper
script as a content_filter are the major options.
I use MIMEDefang on my own machine. It and its sibling MailMunge are
great if you are comfortable with writing a little Perl as your config.
I like being able to reject junk in SMTP, so only the Milter options are
acceptable to me. If you don't care about synchronous rejection (e.g. if
you want to just mark spam or deliver it to a spam folder) then the
non-Milter options work and arguably are more failure-resistant.
would someone be so kind as to point me to a current best practice,
specifically debian and spamassassin? thanks.
There is no such thing. Every mail system is its own unique thing.
Different people want different things from SA and their MTA. Some
people care about synchronous rejections. Some people care about
handling large volume. Some people like to be able to do arbitrary
things to mail before, after, or around SA scanning.
