Hello,
can a postfix guru please look over my easy configuration? I wanted
to create some very easy antispam defense using only postfix
(postgrey).
I created a new smtpd_restriction_classes, which i appended to
smtpd_recipient_restrictions.
my_filtering = check_recipient_access proxy:pgsql:/etc/myconfig/
recipient_check, check_policy_service inet:127.0.0.1:60000,
check_client_access pcre:/etc/myconfig/rbl_check
At first i check if the internal recipient exists with a SQL lookup,
it either returns REJECT if the user isnt found, or DUNNO if the
user is found (to proceed with additional checks). I heard the use
of proxy: is recommended for performance reason - i want to use this
lookup for up to 50 messages/sec - is proxymap the right thing todo
in this case?
After the recipient check, i check for greylisting, default config
of postgrey. Finally im doing an rbl check with reject_rbl_client zen.spamhaus.org
.
Is this the correct order?
I reject with zen before greylisting.
