Different mdbox_rotate_size for primary and alternate storage
by Paolo Cravero 08 May '15

08 May '15

Hello. In order to speed up backups of very very old messages I would like to set two different limits for mdbox_rotate_size. Like, 50M for primary storage and 100M or larger for alternate storage. There is no mention in docs or such a possibility, so I assume it is not possible. Is that correct? While I am at it, is it possible to configure primary storage as maildir (sturdy indexes) and altstorage as mdbox (more delicate indexes)? Thanks, Paolo

Dovecot and data migration
by Alain BERNARD 07 May '15

07 May '15

Hi, Our legacy data store retains a single copy of a message regardless of the number of mailboxes in which that message resides. It does this by creating hard links to that message in the mailboxes containing that message. Thus, when we perform data migration to the server target (Dovecot), the copies of the same message are copied over with the migration process (imapsync). We use the storage format maildir. With a small message store, this means that a lot of messages are duplicated unnecessarily. How to reduce message store size due to duplicate storage of identical messages ? Does a relinking function exist and can be run in real-time mode ? how can we configure Dovecot to deduplicate for all users using a hash to determine whether the file could be already exist ? Thanks in advance. Memo

Mapping other Inbox method (symlink vs ACL)
by Kevin Laurie 07 May '15

07 May '15

Hi, I am trying to map a account(bob(a)mydomain.com) to help(a)mydomain.com. I would like him to see/access Inbox,Sent,Junk,Trash of help(a)mydomain.com . What would you reckon would be the best way to do this? ACL or Symlink? With symlink, I dont think I will be able to set permissions. Is it possible to use ACL to get the entire email account access(the inbox, junk, sent etc.)?

lmpt director and ldap userdb
by Angel L. Mateo 06 May '15

06 May '15

Hello, I've been using dovecot for a long time, but now I'm having troubles with I change I need to make. I have a director server in front of two backend servers. All of these servers are running dovecot 2.1.16. Redirection to backend servers are based in an attribute of a ldap server. My users are defined in this same ldap server. At this moment, for user authentication we use password lookups. My current configuration at both frontend and backend servers is attached. But now I need to change it to bind authentication, so the only change I've made is changing "auth_bind=no" to "auth_bind=yes". After this change, backend servers are working fine. Director servers are also working for POP and IMAP connections, but for LMTP they are returning: May 6 10:23:35 myotis40 dovecot: lmtp(48026): Error: user myuser(a)um.es: Auth PASS lookup failed This error is returned without any ldap lookup, neither connection to backend servers. Any help? thanks in advance. -- Angel L.

only mark as deleted when deleted as default for some mailboxes
by zucca＠systemschmiede.com 06 May '15

06 May '15

Hi list, i wonder if this is possible with some dovecot configuration. Selected mailboxusers will only mark their mails as deleted, when a mail is being deleted through any client. No automatic expunge. This is default behaviour in Outlook, and i think in Thunderbird too, but unfortunately not in Open-Xchange for example. So i was asking myself if it would be possible to simply turn this feature on maybe globally and as a default for some users. Thank you very much for your reply.

dovecot-proxy with managesieve, director and backend dovecot imap
by George Vieira 06 May '15

06 May '15

hi all, I've been tasked to add sieve/managesieve to an existing dovecot cluster running 2.1.7 on debian wheezy which is made up of 2 dovecot-proxy hosts as directors and some back end dovecot imap hosts all running the same version. My problem is that I thought to put the service on the director/proxy hosts since they wouldn't have too much load on it, but when I do I get the following error: Apr 28 11:00:28 master: Info: Dovecot v2.1.7 starting up (core dumps disabled) Apr 28 11:00:28 config: Warning: service auth { client_limit=50000 } is lower than required under max. load (60000) Apr 28 11:00:34 managesieve-login: Error: proxy: host not given: user=<mailchannel(a)mydomain.net>, method=PLAIN, rip=192.168.100.207, lip=192.168.100.119, TLS, session=<3/zPY74UOgDAqGTP> Apr 28 11:00:34 managesieve-login: Info: Aborted login (internal failure, 1 succesful auths): user=<mailchannel(a)mydomain.net>, method=PLAIN, rip=192.168.100.207, lip=192.168.100.119, TLS, session=<3/zPY74UOgDAqGTP> From searching around, only ever saw 1 result which was to add "executable = managesieve-login director" to the managesieve service, but this made no difference at all and the error is the same. So I tried to instead use the back end imap servers, but they throw errors expecting the users password to be the common proxy/director password as below: passdb { driver = static args = user=%u password=crypticpasswordagain } Apr 28 12:03:37 auth: Debug: static(mailchannel(a)mydomain.net,192.168.100.207,<17RTRb8UpADAqGTP>): lookup Apr 28 12:03:37 auth: Info: static(mailchannel(a)mydomain.net,192.168.100.207,<17RTRb8UpADAqGTP>): Password mismatch Apr 28 12:03:37 auth: Debug: static(mailchannel(a)mydomain.net,192.168.100.207,<17RTRb8UpADAqGTP>): PLAIN(85387v92394jks) != 'crypticpasswordagain' Apr 28 12:03:39 auth: Debug: client out: FAIL 1 user=mailchannel(a)mydomain.net So with configs below, how is it best to run managesieve that takes the correct login/password without directing to the cluster (or direct if it's easier but must use real user password)? -- dovecot proxy config -- #

[sieve] extracting address behavior changes beetwen 2.2.13 and 2.2.16
by Marcin Mirosław 05 May '15

05 May '15

Hi all! After upgrading dovecot from 2.2.13 to 2.2.16 I noticed that my sieve filters doesn't catch some emails. I used sieve-test with tracing (it's great tool!) and I can see as below: part of sieve filter: [...] elsif address :is "From" "backup(a)areda.pl" { [...] dovecot-2.2.13: 36: address test 36: starting `:is' match with `i;ascii-casemap' comparator: 36: extracting `From' headers from message 36: parsing address header value `=?UTF-8?B?QmFjdWxhQEFUTQ==?= <backup(a)areda.pl>' 36: extracting `all' part from address `backup(a)areda.pl' 36: matching value `backup(a)areda.pl' 36: with key `backup(a)areda.pl' => 1 36: finishing match with result: matched 36: jump if result is false 36: not jumping dovecot-2.2.16: 36: address test 36: starting `:is' match with `i;ascii-casemap' comparator: 36: extracting `From' headers from message 36: parsing address header value `Bacula@ATM <backup(a)areda.pl>' 36: extracting `all' part from address `Bacula@ATM' 36: matching value `Bacula@ATM' 36: with key `backup(a)areda.pl' => 0 36: finishing match with result: not matched 36: jump if result is false 36: jumping to line 43 So in newer dovecot sieve uses comment not exact email address. Did I wrongly wrote my sieve script? Thanks, Marcin.

Dovecot 2.2.16 doesn't rotate mdbox files
by Басов Евгений 04 May '15

04 May '15

Hello, there's setting in my config file: mail_location = mdbox:/var/vmail/%Ld/%Ln:INDEX=/var/indexes/%Ld/%Ln mdbox_rotate_size = 1M mdbox_preallocate_space = yes mdbox_rotate_interval = 1d As I understand, this settings means that file which contains letters with refcount=0 will be rotated after 23:59 today. I remember letter ID and execute grep whith this one in storage directory. Letter was presented. After that, I removed letter over IMAP protocol, checked and find it again. On the next day check with grep was repeated and letter was finded. After doveadm purge -u user@domain letter was expunged. What's wrong in my configuration?

backup mails from alternate storage
by Lars Täuber 04 May '15

04 May '15

Hi there! It seems that # doveadm backup -v backup -fu $MUSER mdbox:"$BKPDIR/$MUSER/mdbox" doesn't backup all messages stored in alternate storage. mail_location = mdbox:~/mdbox:ALT=/srv/mail/slow/vmail/%n/mdbox I don't know how to debug this. The sizes of the mailboxes in the filesystems of user C are strange: ~/mdbox: # du -sm 2169 ALT: # du -sm 25252 backup: # du -sm 2658 This is with dovecot 2.2.9 on Ubuntu x86_64 14.04.2 LTS. Is this a bug or am I doing something wrong? How can I test if messages stored in the alternate storage are successfully backed up? Thanks Lars

Fatal: Unknown scheme: SHA512-CRYPT. On a Mac-mini

BUT.. On the MAC-Mini, SHA512-CrYPT is unknown. # List of supported schemes is in # http://wiki2.dovecot.org/Authentication/PasswordSchemes # default_pass_scheme = SHA512-CRYPT So the question is, what Encryption should I be using, and is this an Apple thing, or a MySQL thing?

Postpone email delivery with LMTP and Postfix
by Miloslav Hůla 01 May '15

01 May '15

Hi, is there any way, based on userdb/passwdb attribute, how to postpone an email delivery? The purpose is, I need to freeze an account (Maildir++) for a few minutes and new email must not be delivered. But emails must be delivered when account is unfrozen. I found few things about Postfix filters, but I'm not sure it's a good way. Thank you, Milo

A question about Configure time options, and base directories and Defaults?
by Robert Chalmers 30 Apr '15

30 Apr '15

I originally downloaded the sources a few weeks ago, dovecot-2.2.16, and simply did a ./configure make make install I'm running OSX 10.10.3 on a mac-mini. Not being too sure that I was going to go ahead with this whole idea... in any event, I did. BUT... most documentation I come across as I search for answers refers to the base directories being below /etc - as in postfix actually. ie; /etc/dovecot /etc/postfix Which seems logical to me - and appears to be a "default" or standard, at least in most documentation. However, my cavaliere installation put everything below /usr/local, as in /usr/local/etc/dovecot Which has caused me no end of fiddling as I try and remember where things are when I'm working on config files. There even appears to be a /private/etc/dovecot folder, which I seem to have somehow created about a month ago??? but is empty anyway. So, on my Mac I now have these folders/directories. These may have been created by a previous attempt, or by an installation to CutedgeSystems Mailserve. Now redundant. /private/etc/dovecot <---- empty /private/etc/pam.d/dovecot <--- contains login, pop3, ssh etc etc /private/var/spool/postfix/private/dovecot <-- this is a link to the one just above ??? or the other one is a link to this? /usr/libexec/dovecot <-- this contains a link to dovecot-lda [dovecot-lda -> /usr/local/libexec/dovecot/dovecot-lda] that I put in myself because that's where dovecot was looking for it. ========= everything below this line is as a result of the installation from source /usr/local/cutedge/dovecot /usr/local/etc/dovecot /usr/local/include/dovecot /usr/local/lib/dovecot /usr/local/libexec/dovecot /usr/local/sbin/dovecot /usr/local/share/doc/dovecot /usr/local/var/lib/dovecot /usr/local/var/run/dovecot I see from this list in someone else's post, that it's obviously possible - and I should have remembered - to put the files where ever I want them. i.e. /etc/dovecot If I read this list right, it will put the installation into /etc/dovecot - with some in other, appropriate directories. NOT all below /user/local as I have done. --prefix=/usr \ --sysconfdir=/etc \ --libexecdir=\${prefix}/lib \ --localstatedir=/var \ --mandir=\${prefix}/share/man \ --infodir=\${prefix}/share/info \ --with-moduledir=\${prefix}/lib/dovecot/modules \ --disable-rpath \ --disable-static Now for the burning question. Is it possible now to re-configure, then reinstall into the more appropriate directories, then copy the configuration files over. Make the appropriate weeks, and remove the original /usr/local/xxxx installation? Or is that just a step too far for the sake of what is essentially window dressing. The system I might add appears to be working as is? Thanks for any advice from the experts. (Sorry if the formatting in this post gets screwed up. It;s gmail;s web interface) Robert

doveadm -D and -v options

According to doveadm-dsync man page the above two options are valid, but they are rejected when used: tornado # doveadm backup -v -u testuser remote:pi.me.name:4814 backup: invalid option -- 'v' 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>] -d|<dest> tornado # tornado # doveadm backup -D -u testuser remote:pi.me.name:4814 backup: invalid option -- 'D' 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>] -d|<dest> tornado # This is with 2.2.16 (latest -hg). Looks to me like either a bug, or the documentation (man doveadm-sync) is incorrect...? Reuben

quota_over_flag examples?
by E.B. 30 Apr '15

30 Apr '15

I can't find any posts on this list for peoples using quota_over_flag http://wiki2.dovecot.org/Quota/Configuration#Overquota-flag_.28v2.2.16.2B-.… If my userdb is sql what would be best script to use in terms of performance? (I mean if over-quota-flag triggers script every time it changes and the script calls CLI mysql client isn't all this so expensive to spawn a new shell session which spawns a mysql client?) Anyone knows how to use this flag with postfix *making postfix send special reject* "user over quota" note instead of plain SMTP reject?? Is an additional database lookup (restriction class?) unavoidable? :( TIA1 PS Looks like it is tricky almost impossible to make postfix do rejects based on this flag for aliases. (Special query would be a little messy for our schema but i dunno at what point postfix resolves aliases?)

lda and lmtp error after upgrading dovecot
by giorgio paolucci 29 Apr '15

29 Apr '15

Hello everybody, after upgrading dovecot on a debian wheezy installation from the standard package version (dovecot 2.1.7) to dovecot 2.2.13-11 from wheezy-backports, i noticed some errors in my logs...

Trash Plugin bugs
by Alexei Gradinari 29 Apr '15

29 Apr '15

dovecot v2.2.16 I've found a few bugs in Trash plugin. 1. If Quota set only messages limit (without storage limit) then Trash plugin does not expunge any message because Quota plugin sets too_large_r=TRUE. It's because quota_default_test_alloc function does not check if bytes_limit is set. /* if size is bigger than any limit, then it is bigger than the lowest limit */ - if (size > bytes_limit) { + if (bytes_limit > 0 && size > bytes_limit) { *too_large_r = TRUE; break; } 2. Trash plugin does not use bytes_ceil/count_ceil to calculate size_needed/count_needed to expunge. Trash plugin may expunge more messages that nedeed. + if (ctx->bytes_ceil!=(uint64_t)-1 && ctx->bytes_ceil < size + ctx->bytes_over) { + size_needed = size + ctx->bytes_over - ctx->bytes_ceil; + } + if (ctx->count_ceil!=(uint64_t)-1 && ctx->count_ceil < 1 + ctx->count_over) { + count_needed = 1 + ctx->count_over - ctx->count_ceil; + } + /* not enough space. try deleting some from mailbox. */ - ret = trash_try_clean_mails(ctx, size + ctx->bytes_over, - 1 + ctx->count_over); + ret = trash_try_clean_mails(ctx, size_needed, count_needed); 3. Trash plugin does not check 'unlimited' values in bytes_ceil/count_ceil and may overflow them when add expunged size/messages - ctx->bytes_ceil += size_expunged; - ctx->count_ceil += expunged_count; + if (ctx->bytes_ceil!=(uint64_t)-1) { + ctx->bytes_ceil += size_expunged; + } + if (ctx->count_ceil!=(uint64_t)-1) { + ctx->count_ceil += expunged_count; + } See attached patch.

hi everyone could someone show me there sasl configuration section in their dovecot.conf, i have postfix and dovecot setup for virtual users (no system users) everything works fine including tls, i have tried various examples off the web for sasl but they either have obsolete parameters or are for a setup with system users, i would prefer to use dovecots sasl implementation. dovecot --version = 2.1.7 cat dovecot.conf ###################### ###################### disable_plaintext_auth = no mail_privileged_group = mail log_path = /var/log/dovecot.log # auth_verbose=yes # auth_debug=yes # auth_debug_passwords=yes mail_debug=yes # verbose_ssl=yes passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } protocols = "pop3 imap lmtp" protocol imap { mail_plugins = " autocreate" } plugin { autocreate = Trash autocreate2 = Sent autocreate3 = junk autosubscribe = Trash autosubscribe2 = Sent autosubscribe3 = junk } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } protocol lmtp { postmaster_address=postmaster(a)mydomain.com hostname=niya.mydomain.com } ssl_cert = </etc/ssl/certs/mailcert.pem ssl_key = </etc/ssl/private/mail.key ###################### ###################### thanks shadrock
