doveadm sync/backup doesn't sync the metadata?
by Heiko Schlittermann 21 Mar '16

21 Mar '16

Hello, in a current migration project we want to migrate from Cyrus to Dovecot. The Cyrus server stores expiry information as ANNOTATIONS. On the Dovecot side I've set up the metadata/annotations plugin and it is working. But 'dovecot backup …' doesn't seem to sync these metadata? Did I miss something here? Shouldn't the metadata be part of the backup? (I'm using the latest 2.2.22 for sync purposes, as the stock dovecot just crashed when used as 'doveadm backup …') Best regards from Dresden/Germany Viele Grüße aus Dresden Heiko Schlittermann -- SCHLITTERMANN.de ---------------------------- internet & unix support - Heiko Schlittermann, Dipl.-Ing.

Understand the UID value in mailbox debug
by Tobi 21 Mar '16

21 Mar '16

Hi list we have a client who complains that mails from a certain sender are always put into his spamfolder. Our strong guess is that this is an issue with the webmail (Roundcube), but I need some help in understanding the output from dovecot's mailbox-debug. In order to narrow down the source of the problem we activated the mailbox-debug from Dovecot. Now we can see that the mail is moved into the spamfolder. But the strange thing is that a UID is logged which does not exist on the mailserver The following log is the "move" of the mail into the spamfolder Mar 19 11:53:57 backend3 dovecot: imap(REMOVED_FOR_PRIVACY): OmQLrmQubgDAqDIW copy from INBOX: box=INBOX.Spam, uid=58, msgid=<000601d181cd$71401940$53c04bc0$(a)bluewin.ch>, size=314585 Mar 19 11:53:57 backend3 dovecot: imap(REMOVED_FOR_PRIVACY): OmQLrmQubgDAqDIW delete: box=INBOX, uid=1614, msgid=<000601d181cd$71401940$53c04bc0$(a)bluewin.ch>, size=314585 Mar 19 11:53:57 backend3 dovecot: imapREMOVED_FOR_PRIVACY): OmQLrmQubgDAqDIW expunge: box=INBOX, uid=1614, msgid=<000601d181cd$71401940$53c04bc0$(a)bluewin.ch>, size=314585 I do not understand whose UID this is, as it does not exist on the server. Does dovecot create temporary UID or something like that? Or is it more a process ID? Thanks and regards tobi

Re: Setting up public mailboxes - user not found
by Marti Markov 20 Mar '16

20 Mar '16

Hey, I actually went with the method suggested by Steffen Kaiser of creating a separate userdb because I use LDAP and I have an OU which contains all the public mailboxes and was just easier. I setup the userdb like so: userdb { args = /etc/dovecot/dovecot-ldap-shared_mailboxes.conf.ext driver = ldap override_fields = mail=maildir:/home/vmail/Public/.%n } Now when I send an email to office3(a)xxx.com I don’t get any errors and it delivers the message to the office3(a)xxx.com: root@mail:~# ls /home/vmail/Public/.office3/new/ 1458427035.M781836P21781.mail.xxx.com,S=2571,W=2630 1458427705.M750112P23338.mail.xxx.com,S=2501,W=2559 But from any mail client I try I don’t seem to be able to list anything in the Public directory. Am I missing something in the configuration?

v2.2.22 released

19 Mar '16

http://dovecot.org/releases/2.2/dovecot-2.2.22.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.22.tar.gz.sig + Added doveadm HTTP API: See http://wiki2.dovecot.org/Design/DoveadmProtocol/HTTP + virtual plugin: Mailbox filtering can now be done based on the mailbox metadata. See http://wiki2.dovecot.org/Plugins/Virtual + stats: Added doveadm stats reset to reset global stats. + stats: Added authentication statistics if auth_stats=yes. + dsync, imapc, pop3c & pop3-migration: Many optimizations, improvements and error handling fixes. + doveadm: Most commands now stop soon after SIGINT/SIGTERM. - auth: Auth caching was done too aggressively when %variables were used in default_fields, override_fields or LDAP pass/user_attrs. userdb result_* were also ignored when user was found from cache. - imap: Fixed various assert-crashes caused v2.2.20+. Some of them caught actual hangs or otherwise unwanted behavior towards IMAP clients. - Expunges were forgotten in some situations, for example when pipelining multiple IMAP MOVE commands. - quota: Per-namespaces quota were broken for dict and count backends in v2.2.20+ - fts-solr: Search queries were using OR instead of AND as the separator for multi-token search queries in v2.2.20+. - Single instance storage support wasn't really working in v2.2.16+ - dbox: POP3 message ordering wasn't working correctly. - virtual plugin: Fixed crashes related to backend mailbox deletions.

lmtp timeout, locks and crashes

TLS handshake issue
by John Oliver 18 Mar '16

18 Mar '16

dovecot-2.0.9 on CentOS 6.7 The system in question is not connected to the Internet, so I can't copy-and-paste. I have to type anything required :-( Brand-new out-of-the-box install with a really minimal dovecot.conf including: service imap-login { inet_listener imaps { address = 192.168.1.10 port = 143 ssl = yes } } ssl_cert=</etc/pki/tls/certs/dovecot.pem ssl_cipher_list = ALL:!LOW:!SSLv2:!EXP:!aNULL ssl_key =</etc/pki/tls/private/dovecot.pem That's very, very similar to an existing dovecot server on an old VM I need to replace. Certs are self-signed, I know that's a horrible thing to do, but right now we don't have any choice. I'm connecting with Apple Mail 8.2 running on OS X 10.10.5, another thing we have no choice about :-/ The Apple Mail just sits there stupidly. It's "Connection Doctor" just helpfully reports that it can't establish a connection. I can use 'openssl s_client -showcerts -connect mail:143' and see what I expect to see. The dovecot log with lots of verbosity enabled tells me: imap-login: Info: Disconnected (no auth attempts): rip=192.168.1.200, lip=192.168.1.10, TLS handshaking: Disconnected auth: Debug: auth client connected (pid=21006) imap-login: Warning: SSL: where=0x10, ret=1: before/accept initialization [192.168.1.200] imap-login: Warning: SSL: where=0x2001, ret=1: before/accept initialization [192.168.1.200] imap-login: Warning: SSL: where=0x2002, ret=1: SSLv2/v3 read client hello A [192.168.1.200] And that's it... those lines get repeated every minute that Mail is running. I'm not seeing anything in any logs that even hints at what it's unhappy about, or any way to increase verbosity any more. Any hints appreciated! -- *********************************************************************** * John Oliver http://www.john-oliver.net/ * * * ***********************************************************************
