sharing sso between regular mail client and web applications
by Marc 20 Nov '24

20 Nov '24

I am testing a bit with sso with keycloak, I was wondering if/how it is possible that your logged in session between eg Thunderbird and dovecot can be used as a single sign on in webapplications. So as long as you have an active session with dovecot you can access all your web applications without the need to login.

Fatal: sql proxy::sqlite-proxy: Can't open configuration file
by Matt 14 Nov '24

14 Nov '24

Hi, I'm running into a problem where I'm not sure anymore if it's possible to proxy to an SQLite database file using a dict for authentication. The docs are unclear about it and I thought it was not possible as it's not a connection for SQLite but a file-read where the documentation shows different. ov 14 13:57:52 auth: Debug: Loading modules from directory: /usr/lib/dovecot/auth Nov 14 13:57:52 auth: Debug: Module loaded: /usr/lib/dovecot/auth/lib20_auth_var_expand_crypt.so Nov 14 13:57:52 … [View More]

openid / roundcube example
by Marc 14 Nov '24

14 Nov '24

Does anyone have a current config example using openid and with roundcube. I like to add this next to 'regular' logins'. I was able to login once but know I am getting these in the logs " No requests to service for this peer (1 connections exist, 0 pending)" I have added the 2 passdb with links to dovecot-oauth2.token.conf.ext from this manual[1], but it is not really clear if I need these and can just add a config file with openid_configuration_url [1] https://doc.dovecot.org/2.3/configuration_manual/authentication/oauth2/

Hello! I'm using dovecot with keycloak for oauth authentication. My config is: client_id = dovecot client_secret = MY_SECRET introspection_url = https://MY_KEYCLOAK/realms/master/protocol/openid-connect/token/introspect introspection_mode = post pass_attrs = pass=%{oauth2:access_token} Everything worked great on version 2.3.20. After upgrading to version 2.3.21.1 oauth stopped working with errors: auth: Debug: http-client: conn [::1]:443 [1]: Got 401 response for request [Req1: POST … [View More]

Locking box for backups
by Steve Atkins 12 Nov '24

12 Nov '24

I’m running 2.3.19.1 on a system that isn’t set up to support filesystem snapshots. So I’d like to back up my mdbox mailboxes at a filesystem level (with rsync, or something equivalent). I’m assuming that to get a consistent backup I should lock the mailbox while I copy it. How should I acquire a (write) lock on an mdbox mailbox? Cheers, Steve

replication and backup
by Philippe 12 Nov '24

12 Nov '24

Hi all & thanks Aki for adding me to the list. First of all, I'm not a dovecot user yet. For several years now I use cyrus imapd and never saw the urge to switch, until I recently lost random mails from my mailbox which were neither temporally connected nor related in some other way. Fortunately, I had a rolling replication which never expunges, so I was able to restore them. While circumventing some pitfalls during the restore, I learned that the backup and restore procedure cyrus … [View More]

SMTPUTF8 in dovecot lmtp - current status
by Kamil Jońca 12 Nov '24

About a year ago I asked about SMTPUTF8 in dovecot-lmtp, and then dovecod did not handle it. Is that changed? KJ -- http://wolnelektury.pl/wesprzyj/teraz/ A bore is someone who persists in holding his own views after we have enlightened him with ours.

Re: What is the appropriate action for out of memory error for exceeding vsz_limit in my situation?

But if you do colocation and have to rent remote PoP hands to insert the RAM their hourly rate could be hundreds of dollars. If you're renting the entire server you have to ask your service provider for a quote to provision more RAM.
