I'd probably:
- default UseDNS = no, since it provides a false sense of security

- I'd also go for -u0 per default, even though one should probably
double check if that might somehow affect logging as used by prominent
software like fail2ban

- not sure what to do about from="pattern-list"... perhaps adding a
warning there that using domainnames may be insecure anyway,.. perhaps
adding a further option that enables/disables DNS for it?


Apart form that UseDNS seems to be kinda misnomer... normally I'd expect
from the name, that if I say UseDNS=no, then DNS is never used.
But actually it's something different...


Cheers,
Chris.
