Hi,
How to integrate blacklists is well documented. And also how to pass by
these blacklists by
having local configuration files with trusted mail servers can be found on
the mailing lists.
I however cannot find how to use a DNS based whitelist like the nlwhitelist
or the bewhitelist.
I was guessing it should be something like this:
accept message = X-Blacklist-Whitelisted: $sender_host_address is
listed at $dnslist_domain
dnslists = nlwhitelist.dnsbl.bit.nl
warn message = X-Blacklist-Warning: $sender_host_address is
listed at $dnslist_domain ($dnslist_text)
log_message = $sender_host_address is listed at
$dnslist_domain ($dnslist_value: $dnslist_text)
dnslists = sbl.spamhaus.org:virbl.dnsbl.bit.nl:relays.ordb.org
I however would expect that sending a mail through a mailserver that is on
the nlwhitelist would be tagged
with the X-Blacklist-Whitelisted header. This however seems not to be the
case when I tested this.
Or should it be perhaps something like this?:
warn message = X-Blacklist-Warning: $sender_host_address is
listed at $dnslist_domain ($dnslist_text)
log_message = $sender_host_address is listed at
$dnslist_domain ($dnslist_value: $dnslist_text)
dnslists = ! nlwhitelist.dnsbl.bit.nl
dnslists = sbl.spamhaus.org:virbl.dnsbl.bit.nl:relays.ordb.org
Can someone point me to the right direction (if there actually is a right
direction...)
The basic question is that I want to still receive mail from whitelisted
servers that also are on a blacklist.
(for now I use a warning, when I have enough confidence I will add certain
blacklists to a deny statement). If
I can also tag mail with that they come from whitelisted servers that may
be a nice feature but not a necessity.
Sincerly,
Pascal
