Re: [Dovecot] How to troubleshoot LDA or LMTP?

*What doesn't work* I thought the next step would be to execute dovecot-lda manually (as is suggested on the wiki and in numerous newsgroup posts), but I can't figure out how to do this. When I execute it as root and provide my non-root username via the -u option, it hangs. I can see that it spawns a child process that executes as the non-root user (specified with the -u option). So, could someone tell how to execute dovecot-lda manually please?
Maybe use "-d"?
I had no trouble invoking
dovecot-lda -c config-file -d user < mailfileIf it doesn't work for you, I suggest process tracing it.
Also, when does LMTP process messages? When sending mail via SMTP, or when reading mail via IMAP? I would prefer to use LMTP rather than LDA.
The former.

I had no trouble invoking
dovecot-lda -c config-file -d user < mailfile Aha! Piping a message to the process was the step I was not aware of. Thanks Joseph!

does offlineimap provides logs to get to know what mails are newly arriving to your local mail storage, in order to not filter the same message twice or re-filter messages, you've moved around manually?

in order to not filter the same message twice or re-filter messages, you've moved around manually? That is not a problem. The filtering process works perfectly when I manually invoke dovecot-lda. My problem is that I have followed the instructions here:
and here:
http://wiki2.dovecot.org/LDA/Sendmail
and here:
but neither dovecot-lda nor LMTP seem to be triggered whenever I send email from my MUA (Gnus). At least, I *think* I have followed the instructions correctly. Would you like me to post my dovecot config again, and the relevant portion of sendmail.cf?
Thank you very much for your help, I truly appreciate it.

As Stan already pointed out: a local delivery takes place only, when the mail arrives via a MTA. offlineimap synchronizes two IMAP folders, there is no local delivery at your side at all. Hence, neither LDA nor LMTP is invoked.
So I see two ways:
- keep offlineimap to resync your local store back to the server and keep both in-sync.
Then you can: 1a) run offlineimap to get new messages from the upstream server and sync current local messages. 1b) remove the new ones from the local store and feed them _manually_ to the LDA or LMTP. Now the filtering takes place and they are re-added to the mail storage. 1c) maybe: re-run the process until no new messages got downloaded, in order to keep the server in-sync
- no need for server messages in-sync with local message store
2a) setup a local MTA that accepts your domain and drops messages via Dovecot LDA or LMTP. Then get the new messages via fetchmail on a regular basis and hand the messages over to the local MTA.
2b) use fetchmail in combination with Dovecot LDA/LMTP. No local MTA necessary.
fetchmail will see only messages in INBOX as far as I know. So no filtering on the server must take place.

Gnus supports IMAP natively, and even ManageSieve. Use that, don't run a proxy, it's a lot easier.

I'm using dovecot because I'm getting mail from an extremely slow connection, so Gnus blocks the Emacs UI for several seconds, making Emacs unusable. Using a local server eliminates that problem.
