So dovecot cannot expire, reindex, clean, repair, etc root mail? The mail is crontab mail that is sent out to users via mutt. What would be the "right” way to do this? (The cron tasks run as root because they are scanning system logs on behalf of certain users and those scans cannot be run as the user.) -- My main job is trying to come up with new and innovative and effective ways to reject even more mail. I'm up to about 97% now.

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
