Hi!

It is required to collect statistics about the time of the last IMAP and POP3 login of the user and the delivery of letters to him via lmtp. The last-login plugin is perfect. But I don't want to use heavy databases as the mail system service is served by the Oracle DB.

The most suitable option, as I see, is to store statistics in the sqlite DB, but after going through all the options in the configuration file, I could not use sqlite.

When writing in configuration: plugin { driver=sqlite last_login_dict = sqlite:statsdb last_login_key = last-login/%s/%u/%r last_login_precision = ms }

I am getting an error: Oct 4 17:01:41 nms4 dovecot: imap(new_ver_test@test2.aroma.ru)<154597><q0VJ5jXq9o4KAQDI>: Error: last_login_dict: dict_init(sqlite:statsdb) failed: Unknown dict module: sqlite

I did the last-login plugin setup exactly according to the instructions: https://doc.dovecot.org/configuration_manual/mail_location/obox/last_login_p...

I am using standard debian packages. Desperate, I built latest dovecot version from source, but got exactly the same error.

Tell me, please, is it possible to use a dictionary in sqlite format to collect last-login plugin statistics? And how should I describe it in the configuration file?

Sincerely, Oleg
