Milter-greylist

describe their servers and settings...)

We have  17000 users and run several domains. We use milter-greylist on 
the
2 mx-servers we have, running Solaris 9.

We autowhite after 1 minute, keep autowhite for  14 days and timeout
greylist entries after 5 days.

We have  90000 incoming connetions/day (not the same
as incomiing letters, since these can be retries on the same or
the secondary mx-server.)

We deliver  14000 letter/ day.  (Greylisting works...)

We have 250000 greylisted entries in the database, which should mean
approx 50000 letter are stopped each day.

Right now we do not use lazyaw, but I'm thinking of turn this on.
(How many uses this. I'd like to hear about + and -.)

Database is 31 MB, Size of milter-process is about 60Mb.

We've had small problems with MTAs( a few)  not understanding the
temporary error code, and fixed this by whitelisting these.

People are generally very satisfied with the result. Those who are not
can get this turned off. Just be very clear when you start and inform
what is happening.
