Client shows incorrect message counts
by Antonio Leding 11 Aug '20

11 Aug '20

Hello all… First, a disclaimer…I am aware that this is very likely not a Dovecot related issue but I am truly pulling whatever hair I have left out of my head and given the brain-power of this mailer, I thought someone might know what is going in here. The issues is this… I check the message counts for a given account using doveadm and get a given number. I then configure the same account in 3 mail clients: Apple Mail, Mailmate, and Thunderbird. Both the Mailmate and Thunderbird message counts match exactly with the doveadm numbers. Apple Mail is low in almost all cases. I have tried every idea I have found including: — Delete and recreate the mail account — Rebuild mailbox — Resync mailbox — Reindex Spotlight — Removing the "~/Library/Mail/V*/Envelope*” files; restart Mail — Remove the entire "~/Library/Mail/V*” directory; restart Mail So, at wit’s end and again, apologies for this not being a Dovecot-centric issue but I know you are all on top of this stuff and may have an idea… Thanks in advance...

Question about migration 2.2 - 2.3 with replication
by Ralf Becker 03 Aug '20

03 Aug '20

Do both replication nodes need to be updated at the same time? Or can a 2.2(.36.4) node replicate with a 2.3(.10.1)?

Trying to use solr
by Francis Augusto Medeiros-Logeay 02 Aug '20

02 Aug '20

Hi, I am finally trying to use an fts engine with dovecot. My version is 2.3.7.2 under Ubuntu 20.04. I installed solr 7.7.3 and then 8.6.0 to see if this was a version-related error. I copied the schema from 7.7.0 as many people said this was fine. I get the following error when trying to reindex a user's mailbox: doveadm(francis(a)francisaugusto.com): Error: fts_solr: Indexing failed: 400 Bad Request doveadm(francis(a)francisaugusto.com): Error: Mailbox INBOX: Transaction commit failed: FTS transaction commit failed: backend deinit doveadm(francis(a)francisaugusto.com): Debug: auth-master: conn unix:/var/run/dovecot/auth-userdb: Disconnected: Connection closed (fd=10) On Solr I get this error: org.apache.solr.common.SolrException: Exception writing document id 210/9fd7941e8297d25d91600000c3fdd3da/francis(a)francisaugusto.com to the index; possible analysis error: cannot change field "box" from index options=DOCS_AND_FREQS_AND_POSITIONS to inconsistent index options=DOCS at org.apache.solr.update.DirectUpdateHandler2.addDoc(DirectUpdateHandler2.java:246) Parallel to this, I got some log messages on Solr before attempting to reindex the user (sorry for the garbadged text: TIME (LOCAL) LEVEL CORE LOGGER MESSAGE 7/21/2020, 6:38:47 PM WARN false x:dovecot SolrResourceLoader Solr loaded a deprecated plugin/analysis class [solr.TrieLongField].

Migrating from qmail server, invalid option "o" in dsync
by Justin Coleman 01 Aug '20

01 Aug '20

Hi folks, I have an old server running qmail with several years of mails in maildir format I want to migrate to a new server, without requiring fresh client download of everything. Old server is debian 6(?). Local IP is 192.168.0.1. New server is Debian 10, local IP is 192.168.0.25. I have dovecot 2.3.4.1 (latest from apt stable) installed and apparently working - if I manually copy the home directory for my account, I can connect (using thunderbird) and I get all the emails appearing as new, forcing redownload. Seems like the new config is at least functional. I'm trying to follow the migration guide at https://wiki2.dovecot.org/Migration/Dsync, but I am getting an error message: root@newserver:~# doveadm backup -R -u _user_ -o pop3c_user=_user_ -o pop3c_password=_password_ backup: invalid option -- 'o' doveadm backup [-u <user>|-A] [-S <socket_path>] [-fPRU] [-l <secs>] [-r <rawlog path>] [-m <mailbox>] [-g <mailbox_guid>] [-n <namespace> | -N] [-x <exclude>] [-s <state>] [-t <start date>] -d|<dest> Have tried this a couple different ways and according to everything i can find -o should be valid.

imap doesn't like my passwd
by James 31 Jul '20

31 Jul '20

I spent days on this problem. I have dovecot setup to use SSL and IMAP. I also have a pop account that I had no trouble getting working. Both use PAM authentication on Linux. openssl s_client -connect localhost:993 a login test_user test_secure_password The response I got back was: a BAD Invalid characters in atom I changed the password to "abc" and it worked. The secure password used to work but it was a different architecture (x86_64 I think). The current architecture is armhf. It may be different versions of the software too. Dovecot v2.1.7

dovecot replication and pop3 deletion
by Nigel Metheringham 30 Jul '20

30 Jul '20

Hi, I am investigating the use of dovecot for a voicemail storage system (which is effectively a SMTP/POP3 system), which we want to use replication to give us some resilience. Tests have mostly been on dovecot 2.3.8 (9df20d2db) - as packaged on Centos 8 - but I have also used a couple of similar versions on different platforms, so this is not a specific build problem. The platform has replication working, over an SSL TCP link, for delivery. With the pop3 configuration as default as is possible (although the mail_plugins are explicitly included into the protocol sections to ensure notify and replication is called for), any pop3 delete operation does not cause a notify or replication operation. The two servers show the mailboxes in a different state up until something else prods a replication into progress. I would suggest that a pop3 delete/expunge of a message should be flagged as a mailbox change can cause a notify/replication, and that the current behaviour is a bug. There are workarounds to this, and I am considering adding a note to the wiki page https://wiki.dovecot.org/Replication to flag this - not sure what your wiki editing policy is. # Workaround 1 - Change pop3 deletion to set a flag If the setting pop3_deleted_flag = '$POP3Deleted' is added, then rather than the mail being deleted, it is flagged, and this change causes a notification and replication to the other server. However since the mail is not actually deleted, you additionally need another (cron?) task to periodically remove flagged mail, for example:- doveadm expunge -A MAILBOX inbox KEYWORD '$POP3Deleted' # Workaround 2 - Use Lazy Expunge You can use the lazy_expunge plugin - this has the same effect, and automates the removal of the messages after a period of time. https://doc.dovecot.org/configuration_manual/lazy_expunge_plugin/ For example, you can set the following changed config fragments:- mail_plugins = $mail_plugins notify replication lazy_expunge namespace inbox { separator = / prefix = inbox = yes # automatic lazy expunge mailbox mailbox .EXPUNGED { autoexpunge = 3 days autoexpunge_max_mails = 1000 } } plugin { # Move messages to an .EXPUNGED mailbox lazy_expunge = .EXPUNGED } Nigel. -- [ Nigel Metheringham --------------------------- nigel(a)dotdot.cloud ] [ Ellipsis Intangible Cloudy Technologies ]

Migration from one server to 2 new servers
by Kishore Potnuru 28 Jul '20

28 Jul '20

Hi I am in the process/planning of moving from my existing dovecot imap/pop3 server to 2 new servers (for HA/Resilience). I will be implementing dovecot replication on new servers. Please find my current and new servers versions. My Current Production Server details: ======================== Linux OS - Red Hat Enterprise Linux Server release 6.5 (Santiago) Dovecot version - 2.0.9 Postfix version - 2.6.6 ======================== New Servers: ========================== Linux OS - Red Hat Enterprise Linux Server release 7.7 (Maipo) Dovecot version - 2.2.36 (1f10bfa63) Postfix version - 2.10.1 ========================== What is the best way to stop/copy/migrate the current production data to the new servers? I am planning the following steps. Not sure if it is correct or not. 1. Stop the Postfix services on the old server and wait for few mins. So that no new emails will be coming to the old servers. Existing emails will be delivered to the receipients. 2. copy/migrate the data from old server to new servers. Please suggest what is the best way? 3. I see that dovecot version(2.0.9) in old production server, I do not know the which is the best option? see the options in the current version. ================================= [root@prodcution ~]# doveadm usage: doveadm [-Dv] [-f <formatter>] <command> [<args>] altmove [-u <user>|-A] [-S <socket_path>] <search query> auth [-a <auth socket path>] [-x <auth info>] <user> [<password>] config [doveconf parameters] director add|flush|map|remove|status dump [-t <type>] <path> expunge [-u <user>|-A] [-S <socket_path>] <search query> fetch [-u <user>|-A] [-S <socket_path>] <fields> <search query> force-resync [-u <user>|-A] [-S <socket_path>] <mailbox> help <cmd> import [-u <user>|-A] [-S <socket_path>] <source mail location> <dest parent mailbox> <search query> kick [-a <anvil socket path>] [-f] <user mask>[|]<ip/bits> log find|reopen|test mailbox create|delete|list|mutf7|rename|status|subscribe|unsubscribe penalty [-a <anvil socket path>] [<ip/bits>] purge [-u <user>|-A] [-S <socket_path>] pw [-l] [-p plaintext] [-r rounds] [-s scheme] [-u user] [-V] reload search [-u <user>|-A] [-S <socket_path>] <search query> sis deduplicate|find stop user [-a <userdb socket path>] [-x <auth info>] <user mask> [...] ================================= Please suggest me.
