whitelist for policyd ?

[rbtux]

add

check_client_access hash:/etc/postfix/policyd_whitelist,

before

check_policy_service inet:127.0.0.1:12525


then open /etc/postfix/policyd_whitelist and put:

ip.of.problem.server OK

in there.

You can also do that with the recipient address (use check_recipient_access instead of check_client_access) but that is not recommandable because the sending server is the problem here...
