Thanks,
I saw several  'clean message'  messages in maillog, but these did not
seem to follow timeouts (I didn't see any timeouts in the log), my
values for the milter are:

F=, T=C:15m;S:4m;R:4m;E:10m

Which should I increase, by how much?

By DNS in spamassassin do you mean the dns_available switch?
