And when using fchown($FileDescriptor, 2000, 2000) there is no error. I can't find a way to tell dovecot to use uid & gid 2000 when he tries to do fchown. If I create a directory structure manually, everything works well. Maybe we can make some parameter in config, telling that we are using virtiofs and skip EINVAL when doing fchown...

Auth timeout after reload
by rudolf＠padaru.de 29 Nov '24

29 Nov '24

Hello everyone, I have a Dovecot running and can often observe that the auth process goes wrong if a reload occurs at the moment of authentication. I have installed dovecot 2.3.21.1 on ubuntu 20. Whether the error also occurs under other versions, I cannot say at the moment. I have included three examples from the mail log: ## start logs ## # 1 # Nov 27 11:28:18 <myServer> dovecot[946292]: auth: Debug: sql(<myUser>,<myIP>,<I1eibOInIOW5zIKi>): Finished passdb lookup Nov 27 11:28:18 <myServer> dovecot[946292]: auth: Debug: auth(<myUser>,<myIP>,<I1eibOInIOW5zIKi>): Auth request finished Nov 27 11:30:49 <myServer> dovecot[946292]: auth: Error: plain(<myUser>,<myIP>,<I1eibOInIOW5zIKi>): Request 946296.13397 timed out after 151 secs, state=3 Nov 27 11:28:18 <myServer> systemd[1]: Reloading Dovecot IMAP/POP3 email server. # 2 # Nov 27 09:05:08 <myServer> dovecot[2940195]: auth: Debug: auth(<myUser><myIP>,<nK2cbOAnaMGiIdFS>): Auth request finished Nov 27 09:07:38 <myServer> dovecot[2940195]: auth: Error: plain(<myUser>,<myIP>,<nK2cbOAnaMGiIdFS>): Request 2940206.363 timed out after 150 secs, state=3 Nov 27 09:05:07 <myServer> systemd[1]: Reloading Dovecot IMAP/POP3 email server. # 3 # Nov 27 10:02:18 <myServer> dovecot[3736041]: auth: Debug: auth(<myUser><myIP>,<1v4HOeEnWtG5zIKi>): Auth request finished Nov 27 10:04:48 <myServer> dovecot[3736041]: auth: Error: plain(<myUser>,<myIP>,<1v4HOeEnWtG5zIKi>): Request 3736048.4962 timed out after 150 secs, state=3 Nov 27 10:02:18 <myServer> systemd[1]: Reloading Dovecot IMAP/POP3 email server. ## end logs ## You can clearly see that the sql query works, but then the auth-worker seems to hang. I suspect that the auth-worker sends the request to the DB, receives the response and is then killed before it can log in the user via imap. This then leads to some users not being able to log in for a long time. I write many configs on the server automatically, then I always run a reload so that the changed config is accepted. Is this a bug or do I have to change something in my setup?

"INBOX can't be deleted" error when syncing from imapc
by Andy Balholm 28 Nov '24

28 Nov '24

I'm syncing mail from an IMAP server to local Maildirs with `doveadm backup -R`, and I sometimes get an error the second time I sync an account: > Mailbox INBOX sync: mailbox_delete failed: INBOX can't be deleted. I've figured out that the sync completes the first time without an error, but the UIDVALIDITY of the INBOX Maildir doesn't match the UIDVALIDITY on the IMAP server. Then the second time doveadm detects the mismatch and wants to delete the INBOX, but it can't because Maildir INBOXes can't be deleted. So I think the root cause is that the INBOX is being created with the wrong UIDVALIDITY in the first place. It only seems to happen when there are no messages in the INBOX on the server at the time the Maildir is created, but it doesn't seem to happen all the time. Is there anything I can do to make the sync job run smoothly? Andy

Director to keep redirecting users to the same server even it is down

bug? dsync extremely much slower on forward than reverse direction
by Bjørnar Ness 27 Nov '24

27 Nov '24

I have been experimenting with dsync lately, and to my surprise I found that dsync in forward direction is extremely slow compared for reverse (-R) direction for the exact same data, disk caches flushed both times. I have created a docker-compose setup to prove my findings. Am I missing something here, or is this a bug? link to tests: https://github.com/bjne/dovecot-dsync-benchmark -- Bj(/)rnar

How to get the X-Original-To: header added for LMTP? I tried adding: lda_original_recipient_header = X-Original-To But that didn't add the header for mail over LMTP. I couldn't find anything else in the docs.

Extended LIST not working
by tim＠linux-daus.de 25 Nov '24

25 Nov '24

Hi, i try to use extended LIST command but it doesn't work out. I wonder if there is any option necessary to enable it or some option that prevent using extended LIST commands (for example Courier compatible namespace config). I didn't find anything in the documentation. Did anyone notice a similar behavior? curl -u $IMAPUSER:$IMAPPW imaps://... -X 'STATUS INBOX (MESSAGES UNSEEN)' * STATUS INBOX (MESSAGES 105 UNSEEN 79) curl -u $IMAPUSER:$IMAPPW imaps://... -X 'LIST "" "INBOX" RETURN (STATUS (MESSAGES UNSEEN))' * LIST () "." INBOX Best regards, Tim

Authentication hangs on before SSL initialization
by Matt 22 Nov '24

22 Nov '24

I'm running into below probem; my ath is stuck on initializing SSL. Certificates are fine, cert-chain is tested and auth no further errors are shown. Comparing to the default configuration from the docs it's pretty the same and up-to-date so I'm curious what cloud cause this. Also CHMOD on files has been checked.
