v2.2.36 release candidate released
by Timo Sirainen 04 May '18

04 May '18

https://dovecot.org/releases/2.2/rc/dovecot-2.2.36.rc1.tar.gz https://dovecot.org/releases/2.2/rc/dovecot-2.2.36.rc1.tar.gz.sig v2.2.36 is hopefully going to be the last v2.2.x release. Please test this RC well, so we'll have a good final release! v2.3.2 is still going to take a couple of months before it's ready. * login-proxy: If ssl_require_crl=no, allow revoked certificates. Also don't do CRL checks for incoming client certificates. * stats plugin: Don't temporarily enable PR_SET_DUMPABLE while opening /proc/self/io. This may still cause security problems if the process is ptrace()d at the same time. Instead, open it while still running as root. + doveadm: Added mailbox cache decision&remove commands. See doveadm-mailbox(1) man page for details. + doveadm: Added rebuild attachments command for rebuilding $HasAttachment or $HasNoAttachment flags for matching mails. See doveadm-rebuild(1) man page for details. - dsync: Lock file generation failed if home directory didn't exist - Snippet generation for HTML mails didn't ignore &entities inside blockquotes, producing strange looking snippets. - imapc: Fix assert-crash if getting disconnected and after reconnection all mails in the selected mailbox are gone. - pop3c: Handle unexpected server disconnections without assert-crash - fts: If mails contained NUL characters, the text around it wasn't indexed. - Obsolete dovecot.index.cache offsets were sometimes used. Trying to fetch a field that was just added to cache file may not have always found it.

expiring mail from root's Maildirs?
by ＠lbutlr 04 May '18

04 May '18

I would like to delete old mail from root's sent mailbox but doveadm throws errors when I try to do this, not wanting to process root's mail at all (I am running the commands as root, naturally) # doveadm expunge -u root mailbox Sent SENTBEFORE 1-Apr-2018 doveadm(root): Error: Invalid settings in userdb: userdb returned 0 as uid doveadm(root): Error: User lookup failed: Invalid user settings. Refer to server log for more information. The error makes me think this is intentional, and I can see that makes a sort of sense, but it still leaves me with a Sent box that grow forever until I manually go in and remove old mails. I am using passed for userdb and pam for passdb: passdb { username_filter = "!*@*" driver = pam } userdb { driver = passwd } Can I do this with doveadm or am going to have to resort to either manually removing the mail (hah!) or just crontabbing a task to remove the files more than 30 days old?

Use of NO-NOSELECT in mail_location
by Joseph Tam 03 May '18

03 May '18

I enabled NO-NOSELECT in mail_location as it seemed to be an optimization without negative consequences. The wiki states NO-NOSELECT : Automatically delete any \NoSelect mailboxes that have no children. These mailboxes are sometimes confusing to users. Also if a \NoSelect mailbox is attempted to be created with "CREATE box/", it's created as selectable mailbox instead. The last sentence is important: if you allow this, you won't be able to create folders (i.e. directories); this caught me offguard. If you use mbox, this is something you don't want to enable.

v2.3.1: Event leaked (parent=(nil)): http-client.c:137 and 439
by Milan Knížek 03 May '18

03 May '18

Hi, After upgrade to dovecot 2.3.1, many IMAP clients cause errors in dovecot log: May 01 20:15:51 tiger dovecot[21985]: imap: Warning: Event 0x555fd3c01630 leaked (parent=(nil)): http-client.c:137 May 01 20:15:51 tiger dovecot[21985]: imap: Warning: Event 0x555fd3c00140 leaked (parent=(nil)): http-client.c:439 Namely: * roundcube 1.3.3 * offlineimap * nextcloud mail app Despite the errors, the basic functionality seems to work - mails are received by the client. However, the GUI clients display an "internal server error" message window on each refresh. Some other clients do not create any issues: * MailDroid (Android) * getmail Anybody got a similar behaviour? -- Milan Knížek | knizek.confy(a)gmail.com

Hello Dovecoters, I am using dovecot-2.2.10-8.el7.x86_64 on RHEL 7.4 When I backup mdboxes (using SIS) using this command doveadm -Dv -o plugin/quota= sync -1f -u user1(a)user.com mdbox:/mailbackup/user1 mails get backedup but all m files are not copied. Last file copied is m.4 If I run the command again I get below error I tried with doveadm backup command as well (many times). Error: Corrupted dbox file / mailbackup/user1/storage/m.4 (around offset=3732536): EOF reading msg header (got 0/30 bytes) Result is all mails are not backedup. Destination is a folder on a NAS with NFS mapped to the server. Thanks/DP --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

by André Rodier 29 Apr '18

Hello, I am actually testing dovecot fts search, using doveadm fts lookup. I run this command: doveadm fts lookup -u andre subject "Test" And this generate this error: doveadm(andre): Panic: file mail-storage.c: line 1694 (mailbox_get_open_status): assertion failed: (box->opened) doveadm(andre): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x95e92) [0x7fa7ac9e8e92] -> /usr/lib/dovecot/libdovecot.so.0(+0x95f19) [0x7fa7ac9e8f19] -> /usr/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7fa7ac97ea91] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_get_open_status+0x68) [0x7fa7accb5f68] -> /usr/lib/dovecot/modules/lib21_fts_solr_plugin.so(+0x494d) [0x7fa7ab90394d] -> /usr/lib/dovecot/modules/lib20_fts_plugin.so(fts_backend_lookup+0x4d) [0x7fa7abf6861d] -> /usr/lib/dovecot/modules/doveadm/lib20_doveadm_fts_plugin.so(+0x2821) [0x7fa7aabff821] -> doveadm(+0x28fcd) [0x5617545e8fcd] -> doveadm(+0x29ba8) [0x5617545e9ba8] -> doveadm(doveadm_cmd_ver2_to_mail_cmd_wrapper+0x21c) [0x5617545ea9ec] -> doveadm(doveadm_cmd_run_ver2+0x555) [0x5617545f9d25] -> doveadm(doveadm_cmd_try_run_ver2+0x37) [0x5617545f9d77] -> doveadm(main+0x1da) [0x5617545d9afa] -> /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xf1) [0x7fa7ac5d42e1] -> doveadm(_start+0x2a) [0x5617545d9eda] Do I have to do anything special to test the dovecot fts index with doveadm lookup?

Listening on multiple ports
by Derek Harding 28 Apr '18

28 Apr '18

Hi, I want dovecot to listen for imaps (ssl) on both 993 and a non-standard port 8839. I've tried using variations on the inet_listener entries in 10-master.conf as shown in a couple of threads on here but none of the attempts have worked. Can someone provide me with a cut-and-paste solution and confirm into which file it should be placed (i.e. is the dovecot.conf format using the inet_listener = {address} appropriate)? -- Best wishes, Derek

Virtual mailbox doesn't refresh without deleting indexes
by Bret Martin 26 Apr '18

26 Apr '18

Hello, I have a virtual mailbox with the following dovecot-virtual file: mdbox/* -mdbox/Archive/* -mdbox/Junk -mdbox/Notes all younger 604800 not deleted This works at first, but after messages are older than 7 days, they continue to appear in this mailbox forever. Even if I close all IMAP clients and reconnect, I can't get the mailbox to omit the older-than-7-days messages without deleting its indexes. I have other virtual mailboxes that update as expected, but I don't think any of those are date-based. For example, this one "refreshes" as I'd expect: mdbox/* -mdbox/Archive/* -mdbox/Junk flagged Am I doing something wrong with the first virtual mailbox I mentioned above? I'm using dovecot 2.2.13 on Debian GNU/Linux. Thanks! --Bret
