Thanks Damien - that explains part of it... What ties userdb,
regardless of where it is, to postfix "validation"? I am using the
user "vmail" from one of the examples. There does not appear to be a
reference to "userdb" in main.cf or master.cf.

I tried the changes anyway - and now get a=20

fatal: pipe_command: execvp /usr/local/bin/maildrop no such file or
directory

sigh...

The maildrop courier version....is this what is implemented by the
master.cf line ? How does courier know it's there ? There doesn't
appear to much of imapd * imapd.cnf files in that /etc/courier
directory.
