[Assp-test] fc15 stats

[Marrco <as...@mi...>]

Greylisting working fine here. Filtering seems to be ok. Non local mail
blocked is correct for a weekend and CPU usage is normal, there still is the
anomaly of high message processed per day count, and I still have the fear
that some hosts keep retrying and don't understand the 5xx message, and that
can cause problems (even a small pb valence if the host keeps trying can
cause an extreme block), but fritz knows that, so I'm confident it won't
cause problems.

I had a few problems with fc12-13 about mail being reject with the error
defined in PenaltyError, but I've not been able to find the offending ip in
the logs, nor understand the real reason, but that seems fixed in the last
few builds.

The only thing I would suggest is a higher default for maxSMTPsessions and a
lower one for MAXERRORS and SMTPIDLETIMEOUT

I suggest :

maxSMTPsessions: 36
MAXERRORS: 6
SMTPIDLETIMEOUT: 150

YMMV
