>What is the best solution to avoid backscatter (stop doing)?
It depends on your setup. There are several options out there, and
which one is best depends on your system. For example, there's the
realrcptto patch, but that doesn't work well with some forms of
virtual domains (such as vpopmail). There are several options that
create a list of valid recipients and check against that list, which
works well if your set of valid recipients can be determined ahead of
time and if that set doesn't change too often. There's also the
RCPTCHECK and CHECKENV patches, both of which let you write your own
script for verifying addresses. And there are other options as well.
Which one is "best" depends on you.
