Hello

Following the talks about variables greylisting settings (greylist delay 
and timeout, autowhitelisting timeout) depending on the host:

Such a feature seems extremely interesting to me when combined with DNSRBL. 
One could have a greylisting delay of 45m by default, 1d for hosts listed
in a DNSRBL of xDSL pools, whitelist hosts listed in a DNSRBL of friendly 
networks and so on.

That would be the opportunity to add a blacklist feature

ACL entries would look like this: 
acl blacklist dnsrbl knownspammer.example.net
acl whitelist dnsrbl friends.example.net
acl greylist dnsrbl dslpool.example.net delay 1d timeout 3d autowhite 1d
acl greylist default delay 45m timeout 3d autowhite 1d

Another example, which is a bit less satisfying
acl blacklist dnsrbl knownspammer.example.net
acl whitelist dnsrbl friends.example.net
acl greylist rcpt john.doe@... dnsrbl dslpool.example.net delay 1d
acl greylist rcpt john.doe@... delay 45m
acl greylist rcpt manu@... dnsrbl dslpool.example.net delay 1d
acl greylist rcpt manu@... delay 45m
acl whitelist default

Problem: we have to duplicate a lot of informations. Obviously there is the
need for some factoring syntax. Any comment or idea?
