dovecot-lda without starting dovecot?

[Stephan von Krawczynski]

Hello,

we have a setup where SMTP/LDA and POP3/IMAP are on different physical hosts.
They share the mail data via an external storage.
Now we would like to use dovecot-lda on the smtp host, so we wonder if the
lda binary works without starting dovecot from init. As there will be no
POP3/IMAP usage on this host it seems unnecessary. Nevertheless we cannot
judge if it is still needed for lda&sieve to work.
Your opinion?
