What became of dovecot.passwd?
by Steve Matzura 15 Jun '15

15 Jun '15

Since I've decided to go to version 2, which is a lot more difficult to set up because I have to look in a lot more places than I did with version 1.0.15, what do I do with the old dovecot/passwd or its contents? I see no references to it in any of the stuff in conf.d or doc/dovecot/wiki. As always, thanks in advance.

More about my SSL certificate problem
by Steve Matzura 15 Jun '15

15 Jun '15

Someone, I don't remember whether it was Alex or Urban, asked me to check on my private keyfile to see if it began with "Begin RSA private key". I reported that it does not. Now here's where things get strange: When I ran the command: $ openssl req -nodes -newkey rsa:2048 -sha1 -keyout myserver.key -out server.csr on an old Ubuntu system, `myserver.key' does begin with "Begin RSA private key". But when I run that same command on a Fedora 20 system, the word "RSA" isn't there. Could this have anything to do with my 0906D06C error?

Testin new installation

The first place I went to for test advice and planning recommendations was http://wiki2.dovecot.org/TestInstallation - The very first test failed. Doc says: Next check that Dovecot is listening for connections: # telnet localhost 143 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN] Dovecot ready. If you got "connection refused", make sure that Dovecot is configured to serve the imap protocol and listening on the expected interfaces/addresses. The simplest way to do that would be using doveconf(1): # doveconf protocols listen protocols = imap pop3 lmtp sieve listen = *, :: If the protocols setting shouldn't contain imap so add it. Also make sure, that relevant !include or !try_include configuration lines are not commented. *** End doc extract *** All of the above specified settings are correct.

dsync replication issues with shared mailboxes
by Sergey Schwartz 15 Jun '15

15 Jun '15

Gentlemen, I've setup 2 servers with dsync replication and hit a serious issue - some messages got duplicated thousands times in some shared mailboxes(~5). There is actually no reason to replicate anything from shared name space and I've tried to limit replication scope with just 'inbox' name space but it didn't help. dovecot version ||2.2.18 (2de3c7248922) errors in the logs May 26 13:23:38 mx10 dovecot: doveadm: Error: dsync-remote(korobova@mydomain): Error: Mailbox turkey: Save commit failed: Message has been copied too many times (24498 + 8270) May 26 13:25:16 mx10 dovecot: doveadm: Error: dsync-remote(korobova@mydomain): Error: Mailbox turkey: Save commit failed: Message has been copied too many times (24498 + 8270) May 26 13:26:40 mx10 dovecot: dsync-local(zhelonkina@mydomain): Error: Mailbox booking: Save commit failed: Message has been copied too many times (0 + 32768) May 26 13:30:01 mx10 dovecot: dsync-local(kashchits@mydomain): Error: Mailbox shared/davydjanc@mydomain/russia: Save commit failed: Message has been copied too many times (17139 + 15629) May 26 13:30:01 mx10 dovecot: dsync-local(davydjanc@mydomain): Error: Mailbox russia: Save commit failed: Message has been copied too many times (17139 + 15629) May 26 13:30:01 mx10 dovecot: dsync-local(kapitanova@mydomain): Error: Mailbox shared/davydjanc@mydomain/russia: Save commit failed: Message has been copied too many times (17139 + 15629) May 26 13:30:03 mx10 dovecot: dsync-local(grinenko@mydomain): Error: Mailbox shared/davydjanc@mydomain/russia: Save commit failed: Message has been copied too many times (17139 + 15629) May 26 13:30:03 mx10 dovecot: dsync-local(maslova@mydomain): Error: Mailbox shared/davydjanc@mydomain/russia: Save commit failed: Message has been copied too many times (17139 + 15629) Data was not lost and I've been able to run deduplicate for most of mailboxes, but one mailbox got broken and I had to manually move message to another mailbox force-resync failed fot that mailbox doveadm(l.davydjanc@mydomain): Error: mdbox map /srv/vmail/current/mydomain/davydjanc/storage/dovecot.map.index corrupted: map_uid=361735 refcount too low Hope you guys have an idea how to work it around :) replication.conf dsync_remote_cmd = /usr/bin/ssh -i /home/vmail/.ssh/id_rsa -l %{login} %{host} doveadm dsync-server -u %u service aggregator { fifo_listener replication-notify-fifo { user = vmail mode = 0600 } unix_listener replication-notify { user = vmail mode = 0600 } process_min_avail = 1 } service replicator { unix_listener replicator-doveadm { user = vmail mode = 0600 } process_min_avail = 1 } service doveadm { user = vmail process_min_avail = 1 } service config { unix_listener config { user = vmail } process_min_avail = 1 } replication_max_conns = 50 replication_dsync_parameters = -d -n inbox -l 30 -U plugin { mail_replica = remote:vmail@mx20 } doveconf -n #

Sorry, another faq

I've installed a mailserver according to these instructions: http://www.server-world.info/en/note?os=CentOS_7&p=httpd&f=13 When I try to login to the server through Roundcube webmail I get Connection to storage server failed. So checking on this [12-Jun-2015 11:28:53 +0000]: <6jap13r2> IMAP Error: Login failed for martin from 83.251.209.249. Could not connect to ssl://myserver:993: Permission denied in /usr/share/roundcubemail/program/lib/Roundcube/rcube_imap.php on line 198 (POST /roundcubemail/?.... /etc/roundcubemail/config.inc.php Has the following: $config['default_host'] = 'ssl://mail.myserver.tld'; [address obfuscated] $config['default_port'] = 993; as I understand should be correct. I've been looking at various posts on the net that says the problem is a permission on dovecot, but I fail to find anything to how to fix this as it looks right to me. Any suggestions? /Martin S -- Regards, Martin S

dovecot only partially indexing ... fts
by Infoomatic 14 Jun '15

14 Jun '15

hi, I have a setup using solr as fts, however it seems that when I move messages it does not automatically index the stuff. Also, when using sieve scripts to store messages in different folders I get: dovecot: indexer-worker(user): Indexed 0 messages in testfolder If I get a mail to normal INBOX I get dovecot: indexer-worker(user): Indexed 1 messages in INBOX doveadm index -u user '*' does the trick, however, I have set "fts_autoindex = yes" ... the relevant part of doveconf -n: mail_plugins = fts fts_solr zlib acl quota zlib fts fts_solr acl plugin { fts = solr fts_autoindex = yes fts_solr = url=http://localhost:8983/solr/ break-imap-search sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_extensions = +notify +imapflags } protocol lda { mail_plugins = fts fts_solr zlib sieve acl } protocol imap { mail_plugins = fts fts_solr zlib acl quota imap_acl imap_quota } is this normal behaviour or did I screw something up? TIA, infoomatic

LDA versus LMTP
by Steve Matzura 13 Jun '15

13 Jun '15

My system has a great big four users. The Dovecot wiki says LMTP is more efficient, and someone on IRC told me I'd need it if I were ever to use sieve, which at this time I have no intention of doing. Should I stick with LDA, or just implement LMTP so I'm ready if ever I need it in the future? The bottom line is, it's unclear from the wiki how to explicitly specify use of one or the other, so that's my question.
