Maybe an earlier version....

You do not have two separate programs that talks over the sockets. I agree
with you that the default docs could be better. I mailed them regarding
things I cold not find in the docs and they answered my questions... But the
docs needs to be much better.

Well, I think 20 mail/sec and above is high.

Some versions of ClamAV has been bad. But you can say whatever you want....
We have some ClamAV installation that have ran for a very long time now
without any trouble. Also wiith very high volumes. I have been in your
sitiuation as well, where it wont work, but do work for others. This without
a decent explanation.

Maybe we should end this discussion now as the purpose of this thread was
