Please forgive me if these are silly questions. I am a normal user, not a system administrator. I am using Dovecot as a kind of IMAP caching proxy, i.e. reading IMAP mail via Gnus + Dovecot + Offlineimap. I am trying to enable sieve functionality.

*Desired behaviour* When Gnus (or whatever MUA) asks for new mail from Dovecot, that before Dovecot returns and answer, the sieve rules are executed. Please tell me if I completely misunderstand how the mail system works in this instance.

*Actual behaviour* As far as I can tell, not only are the sieve rules not executed, but also neither LDA or LMTP is invoked.

*What works* Running the scripts manually via sieve-filter works fine. The next time I read from my local dovecot server the mail is all in the desired place.

Also, the LMTP service is running, listening on port 24.

*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?

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.

*My environment* Fedora 19 & sendmail. Is any other information relevant, apart from the dovecot configuration?

Thank you,

John
