[collectd] Plugins for postfix, amavisd-new and powerdns

sorry that it took so long, but I finally got around to set up a virtual
host and install PowerDNS there. I'm currently trying to fit the
recursor statistics into something reasonable.
The statistics I could make sense out of are:
Number of answers/replies by RCODE, i. e. number of answers that were
successful, didn't exist or the server failed.
Milliseconds spent in system/user mode.
Now a long list of values remain. I'd like to know which values are
actually interesting and which I should ignore. For instance:
Answers by time it took answer them. I don't think that's very
interesting, but that's just a wild guess..
Number of entries in the cache. Not sure if that's interesting. Might
be, since the recursor is basically all about the cache - right? What
Overall number of questions. Surely interesting, but it's somehow
unspecific. Aren't there some more detailed counters available?
Queries by query type would be nice, for example.
And so on.. Can you help me deciding what goes in and what is ignored
(or rather dropped from the query)?
Thanks and regards,
