Hello Aki,

let me explain this a bit more. We do not intend to use only some copied
binary. Of course we would do a full installation of dovecot and pidgeonhole,
only we question if it is necessary to start the dovecot init-file bringing up
the dovecot imap/imap-login/pop/pop-login/auth and other processes.
Indeed we have virtual users.

While it might be possible to disable all the other services except master I
must ask why?
How would the users be accessing their mails then?

Hello Sami,

you did not read my first post. We are talking about a multihost installation
where one host does SMTP and LDA, and the other does POP and IMAP (with
dovecot). Now we want to use dovecot-lda for the local delivery _on the SMTP
host_. So there is no need for open POP or IMAP ports and the corresponding
running services.
