Hi, I'm tryng to setup Shared Mailboxes in Dovecot (2.3.14) Cluster as explained here: https://doc.dovecot.org/configuration_manual/shared_mailboxes/cluster_setup/ but I'm not happy: # doveadm acl debug -u test1(a)emailtest.net shared/test2/Sent doveadm(test1(a)emailtest.net): Info: imapc(10.0.0.202:143): Connected to 10.0.0.202:143 (local 10.0.0.203:58054) doveadm(test1(a)emailtest.net): Info: imapc(10.0.0.202:143): Connected to 10.0.0.202:143 (local 10.0.0.203:58056) doveadm(test1(a)emailtest.net): Error: imapc(10.0.0.202:143): Authentication failed: [AUTHENTICATIONFAILED] Authentication failed. doveadm(test1(a)emailtest.net): Error: Can't open mailbox shared/test2/Sent: Authentication failed: [AUTHENTICATIONFAILED] Authentication failed. ACL, master-user, master-password works fine because with regular configuration shared folders works fine and also with master-user or with master-password I can login and see and access to shared/ namespace and shared folders. But when I try to switch location from location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u to location = imapc:~/Maildir/shared/%%u/ [...] imapc_host = 10.0.0.202 imapc_master_user = %u #imapc_user = %u imapc_password = Password imapc_features = search stop working. The relevant error is this: Apr 22 22:57:14 doveadm(test1(a)testemail.net): Info: imapc(10.0.0.203:143): Connected to 10.0.0.202:143 (local 10.0.0.203:58070) Apr 22 22:57:14 doveadm(test1(a)testemail.net): Debug: imapc(10.0.0.203:143): Server capabilities: IMAP4rev1 SASL-IR LOGIN-REFERRALS ID ENABLE IDLE XLIST LITERAL+ AUTH=PLAIN AUTH=LOGIN Apr 22 22:57:14 doveadm(test1(a)testemail.net): Debug: imapc(10.0.0.203:143): Authenticating as test1(a)testemail.net for user test2(a)testemail.net Apr 22 22:57:16 doveadm(test1(a)testemail.net): Error: imapc(10.0.0.203:143): Authentication failed: [AUTHENTICATIONFAILED] Authentication failed.

Please note "Authenticating as test1(a)testemail.net for user test2(a)testemail.net" failed. So my question is, the documentation page is update and right or I missing something? Someone have this setup workings?

How to omit the DH parameter in v2.3.3+ ( as stated in 'Upgrading Dovecot v2.2 to v2.3' )
by J. Sommersberg 27 Apr '21

27 Apr '21

Hi, i just finished tuning my dovecot setup after upgrading to 2.3.7.2. I needed to add the "ssl_dh =„ parameter to my config as stated in the online docs at dovecot.org <http://dovecot.org/>. That was no problem and is well documented there and the hint in the log on startup also helped to quickly identify the problem. After that i was curious and read more and did a lot of research. But i just could not find out how to „omit“ the DH parameter as stated in the online docs: https://doc.dovecot.org/installation_guide/upgrading/from-2.2-to-2.3/ <https://doc.dovecot.org/installation_guide/upgrading/from-2.2-to-2.3/> It says : „Since v2.3.3+ DH parameter usage is optional and can be omitted.“ I trried it in different ways. First i disallowed DH on the ssl_cipher_list like it was suggested in the example in this doc. But it will still give Errors on startup/reload of dovecot. Next i tried ssl_dh = that also did not work. I could not figure out how to „omit“ the DH parameter. Is it just my misinterpretation of the config doc? thanks for clarifying Best regards joerg

doveadm sync duplicating emails
by Paul Robinson 27 Apr '21

27 Apr '21

I'm upgrading a mail server using postfix 2.9.6 and dovecot 2.0.19 to a new server running postfix 3.4.13 and dovecot 2.3.7.2 (using Maildir format on both sides). I had trouble getting doveadm backup to work for one user, while all the others worked straight away. It would complain about problems on the old server in the Maildir/dovecot* files. I managed to get it to work by removing all the dovecot* files under Maildir for that one user (accepting that this would mean clients having to redownload emails). >From that point, a doveadm backup worked. Using roundcube to look at the new mail server, I could see everything arrived. At this point, some mail generated on the new mail server would go to the new mail server, but all other mail is going to the old mail server. I then tried to use doveadm sync -1R to update the new mail server so the new server contains all the mail from the old server plus the new mail that has been locally delivered. What then happened was that all the new emails delivered to the old server since the backup were copied to the new server, and all the emails that were locally delivered on the new mail server were still there. (So far so good). But I also saw that every email that was on the old server before the backup now appeared twice on the new mail server. Running sync again would mean I had three copies of email. The sync ran quickly - much too quickly for these extra copies to have been sent over the network. It appears that the sync made extra local copies on the new server. I see no errors in logs that can explain things. Looking at the email, the files stored in the cur directories are there multiple times; they have different names, but identical content. Trying "doveadm deduplicate -F user-list ALL" ran quickly and to no effect (where user-list is a file with a list of users). Trying "doveadm deduplicate -F user-list -m ALL" takes 100% cpu and a long time to run and still running right now after 4 hours. Judging by the disk space usage freed up, this is going to take a very long time to complete. Has anybody got any idea what might cause this and what change I should make? This was the sync command line: doveadm -vc /etc/dovecot/dovecot-migration.conf sync -1RF user-list imapc: For the backup and sync, I used this as the config: imapc_features = rfc822.size fetch-headers imapc_host = <snipped> imapc_ssl = imaps imapc_port = 993 imapc_user = %n imapc_master_user = master imapc_password = <snipped> mail_prefetch_count = 20 ssl_cipher_list = EECDH+AESGCM+AES128:EECDH+AESGCM+AES256:EECDH+CHACHA20:EDH+AESGCM+AES128:EDH+AESGCM+AES256:EDH+CHACHA20:EECDH+SHA256+AES128:EECDH+SHA384+AES256:EDH+SHA256+AES128:EDH+SHA256+AES256:EECDH+SHA1+AES128:EECDH+SHA1+AES256:EDH +SHA1+AES128:EDH+SHA1+AES256:EECDH+HIGH:EDH+HIGH:AESGCM+AES128:AESGCM+AES256:CHACHA20:SHA256+AES128:SHA256+AES256:SHA1+AES128:SHA1+AES256:HIGH:!aNULL:!eNULL:!EXPORT:!DES:!RC4:!3DES:!MD5:!PSK:!KRB5:!aECDH:!DH mail_location = maildir:~/Maildir mail_home = /var/vmail/%d/%n/ mail_fsync=never Thanks, Paul

failed: Cached message size smaller than expected
by Michael Grant 27 Apr '21

27 Apr '21

Every few days, my mailbox seizes up. No mail come in to my imap clients. I'm getting these errors over and over with my mailbox: Error: Mailbox INBOX: Deleting corrupted cache record uid=371208: UID 371208: Broken physical size in mailbox INBOX: read(/var/mail/mgrant) failed: Cached message size smaller than expected (17212 < 17222, box=INBOX, UID=371208) Error: Mailbox INBOX: UID=371208: read(/var/mail/mgrant) failed: Cached message size smaller than expected (17212 < 17222, box=INBOX, UID=371208) (FETCH BODY[]) Error: Mailbox INBOX: Deleting corrupted cache record uid=371203: UID 371203: Broken physical size in mailbox INBOX: read(/var/mail/mgrant) failed: Cached message size smaller than expected (3904 < 3914, box=INBOX, UID=371203) Error: Mailbox INBOX: UID=371203: read(/var/mail/mgrant) failed: Cached message size smaller than expected (3904 < 3914, box=INBOX, UID=371203) (FETCH BODY[]) My inbox is an mbox file. I'm running dovecot installed on Debian Bullseye, the dovecot packages are all: 1:2.3.13+dfsg1-1 I am running sendmail and using procmail for local delivery. I suspect, but am not certain, that this may be some locking issue between procmail and dovecot but I have never been able to prove that. The final procmail rule which appends messages to my mailbox looks like this, the trailing ':' causes procmail to use a lockfile: :0: /var/mail/mgrant The locking config lines in 10-mail.conf are commented, but I have also tried uncommenting them, did not help: #mbox_read_locks = fcntl #mbox_write_locks = fcntl dotlock Though sometimes it seems to fix itself after a few hours, the only way I have found to fix this quickly is to manually remove the cache files and restart dovecot: rm ~/mail/.imap/INBOX/* systemctl restart dovecot I am not even sure this is a locking issue. Something definitely gets corrupted though. I do have several IMAP clients hitting the same mailbox (phone, laptop, desktop). On the phone, I run K9 and also the gmail client which talks imap. Also using thunderbird, outlook, and w10 mail, though typically not all at the same time. You could definitely say I am stress testing this setup a bit! Any ideas on how to resolve this?

Dovecot integration w/ FreeIPA expired password as well as if over quota login notice; local user can't login
by Robert Kudyba 26 Apr '21

26 Apr '21

As I continue to test freeipa-server-4.9.3-1, on Fedora 33 with dovecot-2.3.14-1 I've run into the following issues with web mail and Dovecot integration. 1. I followed https://www.freeipa.org/page/Dovecot_IMAPS_Integration_with_FreeIPA_using_S… but I couldn't get web mail to login until I used the suggestion from https://blog.delouw.ch/2017/02/19/integrate-dovecot-imap-with-freeipa-using… and changed logins auth_mechanisms = plain gssapi login which allowed logins of FreeIPA Kerberos users. 2. even with auth_mechanisms = plain gssapi login, I could then no longer login to SquirrelMail webmail with any local Unix (non-Kerberized) users. The dovecot logs show: auth: Error: policy(localuser(a)ourdomain.edu,127.0.0.1,<r2eFe+PAvut/AAAB>): Policy server HTTP error: connect(x.x.x.x:8084) failed: Connection refused auth: Debug: policy(localuser(a)ourdomain.edu,127.0.0.1,<r2eFe+PAvut/AAAB>): Policy report action finished auth: Debug: http-client[1]: request [Req2: POST https://x.x.x.x:8084/?command=report] Destroy (requests left=1) auth: Debug: http-client[1]: request [Req2: POST https://x.x.x.x:8084/?command=report] Free (requests left=0) auth: Debug: http-client: conn x.x.x.x[2]: Connection close auth: Debug: http-client: conn x.x.x.x[2]: Connection disconnect auth: Debug: http-client: conn x.x.x.x[2]: Disconnected: connect() failed: Connection refused (fd=23) auth: Debug: http-client: conn x.x.x.x[2]: Detached peer auth: Debug: http-client: conn x.x.x.x[2]: Connection destroy auth: Debug: http-client: host x.x.x.x: Idle host timed out auth: Debug: http-client: host x.x.x.x: Host destroy auth: Debug: http-client: host x.x.x.x: Host session destroy auth: Debug: http-client[1]: queue https://x.x.x.x:8084: Destroy auth: Debug: client passdb out: FAIL 1 user=localuser(a)ourdomain.edu original_user=localuser imap-login: Debug: Ignoring unknown passdb extra field: original_user imap-login: Info: Aborted login (auth failed, 1 attempts in 3 secs): user=< localuser(a)ourdomain.edu>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured, session=<r2eFe+PAvut/AAAB> 3. If a user was over quota there was no way to tell on the webmail page that they were over quota but the dovecot logs show imap(ouruser): Error: mkdir(/path/to/ouruser/mail/.imap) failed: Disk quota exceeded. Would there be a security risk if the web page displayed a warning that could be generalized to inform the user to either check their quota or password reset being needed?

Live migrating index/control files
by Eirik Rye 26 Apr '21

26 Apr '21

Hello, We are running a director-based dovecot cluster where the user's maildir and the indexes/control files are, for legacy reasons, stored on separate NFS-backends, i.e.: mail_location = maildir:~/Maildir:CONTROL=/mail/control/%1u/%2u/%u:INDEX=/mail/index/%1u/%2u/%u Both ~/Maildir and /mail/{control,index}/ are separate NFS-mounts, and we now want to consolidate all files to the user's home directory instead. The end goal is to stop using NFS altogether. I have devised a four step plan for gradually migrating the index/control files into the user's maildir, on a per-user basis: 1. Kick the user in an attempt to flush the user's index files: `doveadm director kick <username>` 2. Rsync the index/control files into the user's maildir: `rsync -uav /mail/{index,control}/${user:0:1}/${user:0:2}/${user}/ /mail/${user:0:1}/${user:0:2}/${user}/Maildir/;` 3. Update the (redis-based) userdb for the specific user to override mail_location to use the default CONTROL/INDEX locations: `{"mail": "maildir:~/Maildir"}` 4. Kick the user one last time so that they reconnect using the new settings. Unfortunately, after running this for a small batch of users, we recieved a couple reports that their clients had started to resynchronize and redownload their mailboxes, which is exactly what we're trying to avoid. There are no index related error messages related to the few users that reported these issues. From my understanding, clients become confused when the control files are changed or lost (`dovecot-uidlist` and `dovecot-uidvalidity`), so I suspect the kick + rsync + kick procedure is not robust enough for this. Does anyone have any experience with performing such a migration without taking systems offline for the duration? Any suggestions to make this process more transparent for our users, so as to not induce panic when their mailboxes abruptly appear empty? Best regards, Eirik

Panic: file ostream.c: assertion failed when using mail_filter on RHEL8
by Martijn Brinkers (list) 24 Apr '21

24 Apr '21

Hi, I installed dovecot on a new up-to-date RHEL8 test system and configured a simple mail_filter plugin which only copies the input back to the output (i.e., the filter does nothing special). On RHEL8 I get the following panic when saving the mail. The Dovecot version that comes with RHEL8 is dovecot-2.3.8-4.el8.x86_64 The mail_filter works correctly on an Ubuntu machine )2.2.33.2- 1ubuntu4.7) Any idea what's causing this panic on RHEL8 and how to fix it?

Hi, Mail-filter plugin was removed in version 2.3.14. Any idea why was this removed? Is there a replacement for the mail-filter plugin? Kind regards, Martijn Brinkers
