@ -6,6 +6,18 @@ Wish list:
Disable -DSNAPSHOT and -DNONPROD in makedefs.
postscreen_dnsbl_sites is evaluated in the reverse order, breaking
expectations when different reply patterns have different weights.
We need a compatibility_level feature to correct this.
In the cleanup daemon, open the milter*header_checks greedily,
before the chroot() call. This code is implemented and needs
to be tested.
In the pgsql: client, make the client encoding configurable
with a sensible default (UTF8). This code is implemented
and needs to be tested.
FILTER_README needs some text on multi-instance implementations,
and existing multi-instance references need to be updated.
