Avoid greylist well behaved sites
It can be usefull to look at the greylisting database and possibly improve our ze-policy.txt file:
# ze-printstats -q -l 1d -m rg -n 20 Loading ze-filter configuration Loading default values Reading configuration file : /etc/ze-filter/ze-filter.cf Reloading configuration tables...

Oups, we are greylisting laposte.net which is a well behaved site. So, we can add it to the policy file: vi /var/jchmail/cdb/ze-policy.txt
GreyCheckConnect:laposte.net NO-QUICK or GreyCheckConnect:193.251.214 NO-QUICK
NO-QUICK means that we don't bother about From or To address. Just the client IP stops greylisting.
