Good.  I was a little worried about that. :-)

On a related point: I have been reading over in the postfix user list
archives how they are *really* down on mixing MailScanner and Postfix.
 They say fairly serious queue, email and filesystem corruption is a
certainty.  Yikes.  I'm stressing out now that I just invested a ton
of time coming up to speed on MailScanner over the past 10 days. :-\ 
Anyone have advice for me?  Is it really that bad?  Does the one
instance of Postfix help (or better yet *fix*) this issue?  Do recent
versions make things any better/worse here?

They seem to like amavisd-new.

Glad to help if I can.
