hi all,
debian
etchamavis 2.4.2-6.1postfix 2.3.8-2+etch1perl 5.8.8-7etch6courier 4.1.1.20060828-5 spamassassin
3.1.7-2etch1
y case is very rare and I'm an idiot.
1) Amavis is "supposed" to filter spam, but it seems not to use spamassassin, I
do not understand, it is not used by default?. This is because in a "/etc/
init.d/spamassassin stop" Amavis spam filtering continues as usual.
2) despite modifying the configuration files and even the Amavis amvis ... in
many ways, not to enter a header EMAIL SPAM WITH LABELS.
3) A FILTER FOR USERS connecting SASL, for instance, if I connect to my smtp
TLS from using my cell phone and send email to other users Amavis filter this
email as spam! as you can do that if I set postfix users who connect by TLS go
right.
I copy them down exits q config files can, thanks
