tnx for informations, I already found, that there is serious problems
with mail_chrot. actually it seams smtp-client must be another
separated, no chrooted process (or all LDA), as it is difficult to put
all external binaries and libs required by plugins [at last sieve,
spamassassin etc.] in chroot environment...
