Apparently Postfix does not natively support BATV tags. We'd like to strip these
prvs=-tags from the FROM field because we think our mailman setup has issues with it (sees sender as a non-member).
I should mention I've tried batv-milter, but this gave an error ("smfi_main failed"). And I looked at batv-proxy.pl too.
But this solution seemed better for Postfix and is advised to use in combination with amavisd-new. And it was in the Debian repos, too!
I have tried setting up dkimproxy as a postfix
smtpd_proxy_filter but then the connection to dkimproxy's TCP port (127.0.0.1:10026 in my case) times out.
Now I am not sure if the connection to dkimproxy times out, or if it's relay connection (I send it to amavisd-new as per the configuration below) times out. There seems to be no logging whatsoever for dkimproxy.
# set correct hostname hostname $fqdn-of-my-mailserver # specify what address/port DKIMproxy should listen on listen 127.0.0.1:10026 # specify what address/port DKIMproxy forwards mail to relay 127.0.0.1:10024
Am I doing something wrong?
Has anyone been succesful with BATV filtering and Postfix?
