Milter-greylist

Hello,

I just installed milter-greylist 2.0 beta2 and it works well for a
while, and then I get

Milter (greylist): error connecting to filter: Connection refused by
/var/milter-greylist/milter-greylist.sock

in the maillog.

How can I find out why it stops working? I am using the -v switch, but
I don't see any log entrys at the point of failure.

Is there a way to keep milter-greylist from forking so I can run it in
a terminal session?

I am on redhat 9

Any thoughts would be appreciated.

Mark
