dovecot-lda without starting dovecot?
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?

dovecot-lda does not work without dovecot unless you have physical users and you run the binary as target user. with virtual users it's virtually impossible to achieve.

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.

You could configure dovecot in the smtp box without pop3 and imap daemons without any problem (I guess). All you have to do is disable these services in master configuration.
But I wouldn't do it that way. I think is easier to configure LDA in the pop3/imap server and configure SMTP to deliver mail via LMTP to the dovecot server. This way you have to deal with dovecot configuration just in the mailbox server and you don't have to share storage.
