Thanks for the response. I followed your exchanges with Anthony Howe at
the time and ensured that access.db was rebuilt in place as AH
suggested. That fixed the "permissions" and related problems I had then.

However the intermittent problem with whitelisting persisted after that.
If it is related to a memory problem, for example, I am unlikely to
catch it with the necessary level of 'debugging' in operation as I
cannot have that level of debugging running all the time. To enable it I
must restart milter-link at the time I know this particular group of
messages are about to be passed. That very action may well 'fix' the
problem for awhile!

In the new year I may be able to arrange to leave
'verbose=info,trace,db' enabled on one of our busy mail gateways (on
which milter-link does _not_ get restarted) and route the problematic
mail through that gateway only.

[Why can't I just switch a high level of debugging on and leave it? The
answer is because we run a highly resilient service with 8 identical MX
hosts handling traffic for our domains. They account for about 1,000,000
messages/day. I cannot (easily) control which gateway mail gets routed
through. Each gateway logs both to its own filesystem _and_ to a remote
log server. It is the latter that is the problem when large volumes of
debugging info is generated by the gateways - the remote log file can
grow to tens of gigabytes in size each 24 hour period.]
