See the FAQ.

The sweet spot is typically in the range of 5 - 10.

Sadly, nope.  

SMTP is an unreliable transport.  ISPs have no especial obligation to
deliver received mail to their addressed users (no matter that those
users and we may feel differently).  Further, the ISPs won't reveal the
filter controls they are using as they don't want the SPAMmers working
they're way around them (they also change them regularly as the SPAMmers
empirically deduce the values).
