Migration
by Hans Brage 01 Oct '19

01 Oct '19

Hi! I'm currently running an small imap-server on Dovecot 2.2.4 but will retire that server. I've set up an new server with Dovecot 2.3.4 and will migrate the mailboxes (maildir-format) from the old to the new server. I'm planning to restructure the accounts a bit when migrating so I need to move them one by one. Its only a few so thats not a big issue. Both servers are using virtual accounts (users file). I've understood that best method for migration is to run doveadm backup -R from the new server. But I really cant figure out what other parameters or settings that I need to perform that task and if it should be run as user vmail or root. Would be greatful for any tips, hints, links or similiar. Regards, Hans

Best way to move mail from one server to another
by James Brown 01 Oct '19

01 Oct '19

I’d like to migrate to a new server. I only need to transfer the mail store, have already done the users. I’ve seen different recommendations: IMAP-Sync Rsync Doveadmin backup and dsync What are the pros and cons of each? What would be best for me? I’m thinking that Doveadmin backup is the way to go. Both old and new servers are on same network. New server is running Dovecot 2.3.2.1, old server is 2.2.32. macOS X. Does anyone have any advice or examples? Thanks, James.

WARNING: using attachment_dir with plugin zlib can corrupt mails
by Patrick Cernko 12 Sep '19

12 Sep '19

Hello list, hello Dovecot developers, this week, I discovered a serious bug in Dovecot, that lead to several broken mails on our servers. The bug corrupts the first few characters of the mail header during saving. On our setup, it was almost always only the very first line of text, that was corrupted. Depending on the IMAP client (they seem to request different header fields, ... during mail access), the bug causes the imap process to hang up the TCP connection and log errors like this: > imap(USERNAME)<4767><TeQP4ASOTK5/AAAB>: Error: Corrupted record in index cache file /IMAP/mail/mailboxes/USERNAME/mdbox/mailboxes/Trash/dbox-Mails/dovecot.index.cache: UID 489113: Broken fields in mailbox Trash: read(attachments-connector(zlib(/IMAP/mail/mailboxes/USERNAME/mdbox/storage/m.813))): FETCH BODY[HEADER.FIELDS (RETURN-PATH SUBJECT)] got too little data: 2 vs 122 In our case that finally grabbed my attention, the client was the users iphone that did not display any new messages but his Thunderbird did. The bug seems to be triggered by a bad "interaction" of attachment_dir option and zlib plugin. If you use both, you most likely are affected, too, except you only use zlib plugin for reading previously compressed stored mails. That's also the workaround we use now: zlib plugin only enabled in mail_plugins but no plugin/zlib_save set. The bug occurs on very specific mails. Due to privacy reasons I could not provide sample mails here. Storing such mails seems to trigger the bug reproducible. I attached a very minimal doveconf -n config, that can be used to trigger the bug. If one of the developers is interested, I can try to generate an "anonymized" version of such a specific mail that still causes the issue. I discovered the bug on our productive systems, running latest Dovecot 2.2 release, but the latest 2.3 I used during debugging is affected, too. During debugging, I also found one hint, that might help find the bug: If you store a problematic mail with zlib_save=gz (or zlib_save=bz2) and then disable the zlib plugin in mail_plugins, you can call doveadm fetch -u test hdr all | grep -v ^hdr: | gzip --decompress on test's mailbox with only that one broken mail. This will display the beginning of the rfc822 mail text until gzip terminates with "gzip: stdin: unexpected end of file", approximately after twice the length of the mail HEADER. This might indicate, that dovecot stores the uncompressed size of the header in it's data structures although the mail is stored compressed. I also found a very efficient way to find all affected mails in our setup: doveadm -f flow fetch -A 'user guid mailbox uid seq flags hdr' all | \ grep -a "^[^ ]+ user=" | \ grep -avF ' hdr=Return-path: ' | \ grep -av '.* hdr=[[:print:][:space:]]*$' (runtime for ~6M mails on our servers was 20-30min) This can be even more optimized if you have a powerful storage system with GNU parallel: > doveadm user '*' | parallel "doveadm -f flow fetch -u '{}' 'user guid mailbox uid seq flags hdr' all | grep -a '^user=' | grep -avF ' hdr=Return-path: ' | grep -av '.* hdr=[[:print:][:space:]]*$' || true" (runtime for ~6M mails on our servers was ~4min) The command will give you a list of mails that possibly are affected, check the full output of doveadm fetch -u USERNAME hdr guid GUID | less to verify that the header is really broken. On our systems I found 39 mails within ~12M mails. I was able to recover these mails "manually" by reconstructing the Return-Path header line, importing the fixed mails and expunging the corrupt ones. Before importing, I had to disable zlib_save option obviously.

Case sensitive problem for vacation with dovecot lmtp pigeonhole
by kadafax＠gmail.com 11 Sep '19

11 Sep '19

Hi list, This issue was raised here by John Fawcett on 12/02/19 but got no response. So, as I'm facing the same issue, I would like to try again: When using the vacation sieve extension, if I send an email to user.name(a)mydomain.com it will work, but not to User.Name(a)mydomain.com. Is there a way to make the user part case insensitive so that the vacation auto-reply is fired whatever the way user part is written ? doveconf -n output: # 2.3.5.1 (7ec6d0ade): /usr/local/etc/dovecot/dovecot.conf # Pigeonhole version 0.5.5 (2483b085) # OS: Linux 3.10.0-957.5.1.el7.x86_64 x86_64 CentOS Linux release 7.6.1810 (Core) ext4 # Hostname: myserver.mydomain.com auth_master_user_separator = * auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@* auth_verbose = yes debug_log_path = /var/log/dovecot-debug.log default_client_limit = 10640 default_process_limit = 2128 default_vsz_limit = 0 hostname = mydomain.com info_log_path = /var/log/dovecot.log lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes listen = * log_path = /var/log/dovecot-error.log login_greeting = Welcome mail_gid = vmail mail_location = maildir:/var/vmail/%Ln mail_plugins = quota fts fts_lucene mail_uid = vmail managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date index ihave duplicate mime foreverypart extracttext namespace inbox { inbox = yes location = maildir:/var/vmail/%Ln mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Sent { auto = subscribe special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { auto = subscribe special_use = \Trash } prefix = type = private } passdb { args = /usr/local/etc/dovecot/deny-users deny = yes driver = passwd-file } passdb { args = /usr/local/etc/dovecot/master-users driver = passwd-file master = yes pass = yes } passdb { args = /usr/local/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { fts = lucene fts_autoindex = yes fts_lucene = whitespace_chars=@. quota = maildir:User quota quota_rule = *:storage=30GB quota_rule2 = Trash:storage=+200M quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=80%% quota-warning 80 %u sieve = /var/sieve-scripts/%Ln.sieve sieve_dir = /var/vmail/%Ln/home/sieve } postmaster_address = postmaster(a)mydomain.com protocols = imap pop3 lmtp sieve sieve quota_full_tempfail = yes service auth-worker { user = $default_internal_user } service auth { unix_listener /var/spool/postfix/private/auth { mode = 0777 user = vmail } } service imap-login { inet_listener imaps { port = 993 ssl = yes } process_min_avail = 10 } service imap { process_limit = 2128 } service lmtp { executable = lmtp -L process_min_avail = 15 unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } service managesieve-login { inet_listener sieve { port = 4190 } } service pop3-login { inet_listener pop3s { port = 995 ssl = yes } } service quota-warning { executable = script /usr/local/bin/quota-warning.sh user = nobody } ssl_cert = </etc/letsencrypt/live/myserver.mydomain.com/fullchain.pem ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it userdb { args = /usr/local/etc/dovecot/dovecot-ldap-userdb.conf.ext driver = ldap override_fields = uid=vmail gid=vmail home=/var/vmail/%Ln/home } protocol imap { mail_max_userip_connections = 30 mail_plugins = quota fts fts_lucene imap_quota } protocol lmtp { info_log_path = /var/log/dovecot-lmtp.log log_path = /var/log/dovecot-lmtp-errors.log mail_plugins = quota fts fts_lucene sieve } protocol sieve { mail_max_userip_connections = 20 }

Dovecot Director upgrade from 2.2 to 2.3
by Alessio Cecchi 10 Sep '19

10 Sep '19

Hi, I have a setup with 3 Dovecot Director v2.2.36 and director_consistent_hashing = yes ;-) Now I would like to upgrade to 2.3.7, first only Director and after also Backend. Can works fine a ring of director with mixed 2.2 and 2.3 version? Mi idea is to setup a new Director server with 2.3, stop one server with 2.2 and insert the new 2.3 in the current ring to check if works fine. If all works fine I will replace all Director 2.2 with 2.3 version. Thanks -- Alessio Cecchi Postmaster @ http://www.qboxmail.it https://www.linkedin.com/in/alessice

Ok I'm agree! So, about you, which version can I try to install the 2.2.27 or the previous release of the 2.3 version such as v2.3.2 2018-06-29 or v2.3.1 2018-02-29?

flags not synced correctly with dovecot sync (dsync)
by Dan Christensen 31 Aug '19

31 Aug '19

I'm running dovecot 2.3.4.1 from https://repo.dovecot.org/ on Ubuntu 18.04 on three machines that I'll call server, laptop1 and laptop2. Both laptop1 and laptop2 run dovecot sync against server to keep local copies of my imap folders. Even when I initially had only two machines, laptop1 and server, I occasionally noticed that flags were lost, usually custom flags used by Gnus, but I couldn't reliably reproduce the problem. Now that I have two laptops syncing against the server, the problem has gotten worse and I figured out a way to reproduce it: - on server: create new IMAP folder test, and put two read messages in it - on laptop1: doveadm sync -u user -l 10 -m test -f user@server - on laptop2: doveadm sync -u user -l 10 -m test -f user@server At this point, all three machines show the two messages M1 and M2 as being read. - on laptop1: mark message M1 unread - on laptop2: mark message M2 unread - on laptop1: doveadm sync -u user -l 10 -m test -f user@server Both laptop1 and server have M1 unread, M2 read, as expected. - on laptop2: doveadm sync -u user -l 10 -m test -f user@server Now laptop2 and server have M1 *read*, M2 unread. - on laptop1: doveadm sync -u user -l 10 -m test -f user@server Now laptop1 and the server have both M1 and M2 *read*. - on laptop2: doveadm sync -u user -l 10 -m test -f user@server Now laptop2 has both read as well. The two lines that say "*read*" are wrong in my opinion. dsync propagated a read mark to an unread message, even though that message was marked unread more recently than it was marked read. I usually use stateful sync, and get many related problems. I just did a test in which M1 and M2 started out read, and I started with empty files named dstate.test on laptop1 and laptop2. Then I did the above procedure, using the command doveadm sync -u user -l 10 -m test -s "`cat dstate.test`" user@server > dstate.test At the end, laptop2 and server had both messages unread (which is good), but laptop1 had only M1 unread, and repeated runs of the sync command did not correct this. So the stateful sync failed to detect a change. Are these bugs in dovecot? Is there more information that I can provide? The output of doveconf -n on one machine is below, and the others are almost identical. Thanks for any help!

Autoexpunge not working for Junk?
by Amir Caspi 14 Aug '19

14 Aug '19

Hi all, I set up dovecot a couple of months ago and am having trouble getting autoexpunge=30d to work on my Trash and Junk mailboxes. Not sure why not because I'm not getting error messages in my log. Running "doveadm search -u <user> mailbox Junk savedbefore 30d" shows me many messages (I've got messages back to mid-May, and a couple of other users have them back to early April, although if this setting were working, there should be nothing earlier than June 24). Running a manual doveadm expunge works fine... it's just autoexpunge that seems to not be running at all. I'm using sendmail as the MTA and procmail as the LDA, so dovecot is running purely for IMAP/POP service. Any help is much appreciated. Thanks! doveconf -n: # 2.2.36 (1f10bfa63): /etc/dovecot/dovecot.conf # OS: Linux 3.10.0-957.21.3.el7.x86_64 x86_64 CentOS Linux release 7.6.1810 (Core) # Hostname: REDACTED auth_username_format = %Ln first_valid_uid = 1000 mail_location = mbox:~/mail:INBOX=/var/spool/mail/%u mailbox_list_index = yes mbox_write_locks = fcntl namespace compat1 { alias_for = hidden = yes list = no location = prefix = mail/ separator = / } namespace compat2 { alias_for = hidden = yes list = no location = prefix = ~/mail/ separator = / } namespace compat3 { alias_for = hidden = yes list = no location = prefix = ~%u/mail/ separator = / } namespace inbox { inbox = yes location = mailbox Archive { special_use = \Archive } mailbox "Deleted Messages" { autoexpunge = 30 days special_use = \Trash } mailbox Drafts { special_use = \Drafts } mailbox Junk { autoexpunge = 30 days special_use = \Junk } mailbox "Junk E-mail" { autoexpunge = 30 days special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Spam { autoexpunge = 30 days special_use = \Junk } mailbox Trash { autoexpunge = 30 days special_use = \Trash } prefix = separator = / } passdb { driver = pam } pop3_uidl_format = %08Xv%08Xu ssl_cert = # REDACTED ssl_cipher_list = # REDACTED ssl_dh_parameters_length = # REDACTED ssl_key = # hidden, use -P to show it ssl_prefer_server_ciphers = yes userdb { driver = passwd } --- Amir
