Currently, I'm executing deliver from a wrapper script:
# master.cf:
dovecot-lda unix [...] argv=[...]/dovecot-lda_wrapper.pl ${recipient}

That script finds out the username which must be passed to deliver's -d 
option, because dovecot's user names are not the same as the recipient 
email addresses of the user's, so I can not just execute deliver 
directly with the -d ${recipient} option. This hack prevented deliver's 
exit code to get recognized by postfix.
