[Dovecot] LDA without lookup as non-root?

Timo,

Sorry I didn't see your response until now

Sorry, would you mind being more specific?  If you see my follow-up posts
on this thread, I found a source file with this error message in it (link below)
and reading that code, there is no way to avoid this error for non-system
users (uid's) if you don't use -d.  (looking at the "destination" variable)
