[Dovecot] Upgrading to dovecot2 broke IDLE on one mailer, but not another
by John Stracke 29 Jul '13

29 Jul '13

Last weekend I upgraded my server (complete reinstall, actually), from Debian sarge to wheezy, which brought me from dovecot 1.x (I think) to 2.1.7. It's all working now, *except* that the MUA I use on Android, Kaiten (a fork of K-9), apparently no longer gets IDLE notifications. Before the upgrade, when mail arrived, Kaiten would pop up an Android notification immediately; now, it never does (or it might, hours later, with all the messages it notices at that time--presumably this happens when its background service gets killed off and restarted). The weird thing is that IDLE still works flawlessly with Thunderbird, which suggests this is a protocol interaction between Dovecot 2 and Kaiten. (I plan to check with the Kaiten folks next.) Has anybody here seen this? Is there something I can turn on in Dovecot to help debug it? I did check my old Dovecot settings, and they didn't specify anything non-default about IDLE. Thanks in advance! My configuration from dovecot -n: # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.9.3-x86-linode52 i686 Debian 7.0 log_timestamp = "%Y-%m-%d %H:%M:%S " mail_access_groups = mail mail_location = mbox:~/mail:INBOX=/var/mail/%u mail_privileged_group = mail passdb { driver = pam } protocols = imap pop3 service auth { user = root } service imap-login { inet_listener imap { port = 0 } } service pop3-login { inet_listener pop3 { port = 0 } } ssl_cert = </etc/ssl/certs/dovecot-2009.cert ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } protocol imap { mail_max_userip_connections = 100 } protocol pop3 { pop3_uidl_format = %08Xu%08Xv } and the no-comments version of conf.d/20-imap.conf: protocol imap { imap_idle_notify_interval = 10 mins } -- /==============================================================\ | John Stracke | http://www.thibault.org | HTML OK | | François Thibault |---------------------------------------| | East Kingdom | "Okay, one more time, with *vowels*." | | francis(a)thibault.org | -- Ozy and Millie | \==============================================================/

[Dovecot] how to setup different quota for multiple namespaces
by Andreas Oster 29 Jul '13

29 Jul '13

Hello all, I am using dovecot for some time now but always had very basic configurations. I recently have configured a new, additional namespace in order to move archived mails (Thunderbird Archives) to another storage system. namespace { type = private separator = . prefix = Archives. location = maildir:/var/vmail/archive/%Ln/Maildir subscriptions = yes list = children inbox = no } This works well but unfortunately I cannot find a solution to either ignore this new namespace from quota computation or add a separate quota value for it. I have integrated user authentication with LDAP and fetch some user attributes from LDAP entries: user_attrs = =home=/var/vmail/%Ln/Maildir,=mail=maildir:/var/vmail/%Ln/Maildir/,otherPager=quota_rule=*:storage=%$ I configured the quota plugin in the following way: plugin { quota = maildir:User quota:ns= quota2 = maildir:Archive quota:ns=Archives. quota_rule = *:storage=1G quota_rule2 = ns=Archives.:ignore } unfortunately this does not give the desired result. Folders under the Archives namespace use the same quota as INBOX. Does anyone have an idea how to fix this ? Thank you for your kind help Andreas

[Dovecot] Please help with : undefined symbol: mail_deliver_save_open
by Markus Kalb 28 Jul '13

Greetings dovecot-mailing list! after upgrading from debian squeeze -> debian wheezy and therefore making the big dovecot jump from 1.x to 2.x we are stuck with one final(?) error that we can't get fixed. During login attempts the following is written to the logfiles. Error: dovecot: imap: Error: dlopen(/usr/lib/dovecot/modules/lib90_sieve_plugin.so) failed: /usr/lib/dovecot/libdovecot-sieve.so.0: undefined symbol: mail_deliver_save_open Searching the mailinglist and google in general the only thing i could find was that this error could be connected to loading the sieve plugin outside of lda. But as you can see in the attached config dump, we only load it inside the lda protocol block. ciao markus Our setup: > dovecot --version 2.1.7 > dovecot -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-686-pae i686 Debian 7.1 auth_debug = yes auth_mechanisms = plain login digest-md5 cram-md5 auth_verbose = yes mail_debug = yes mail_plugins = acl fts fts_solr mail_shared_explicit_inbox = no 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 ihave imapflags notify namespace { hidden = no list = children location = maildir:/home/lists/.mail/:CONTROL=%h/.mail/private/.imap/shared/control:INDEX=%h/.mail/private/.imap/shared/index prefix = lists/ separator = / subscriptions = no type = shared } namespace { hidden = yes list = no location = maildir:/home/security/.mail/:CONTROL=%h/.mail/private/.imap/shared/control:INDEX=%h/.mail/private/.imap/shared/index prefix = security/ separator = / subscriptions = no type = shared } namespace { hidden = yes list = children location = maildir:/home/dsys/.mail/:CONTROL=%h/.mail/private/.imap/shared/control:INDEX=%h/.mail/private/.imap/shared/index prefix = duales_system/ separator = / subscriptions = no type = shared } namespace inbox { hidden = no inbox = yes list = yes location = mbox:%h/.mail/private:INBOX=/var/mail/%u mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = separator = / type = private } passdb { args = scheme=DIGEST-MD5 username_format=%u /etc/dovecot/passwd driver = passwd-file } plugin { acl = vfile:/etc/dovecot/acls:cache_secs=300 sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_extensions = +imapflags +notify } protocols = " imap sieve" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } } service imap-login { inet_listener imap { port = 143 } } ssl_cert = </etc/ssl/certs/SERVER.pem ssl_key = </etc/ssl/private/SERVER.key userdb { args = username_format=%u /etc/dovecot/passwd default_fields = mail_plugins=sieve system_groups_user=%u driver = passwd-file } protocol lda { mail_plugins = acl fts fts_solr sieve } protocol imap { mail_max_userip_connections = 20 mail_plugins = acl fts fts_solr } # dpkg -l '*dovecot*' |grep ii | cut -c 0-60 ii dovecot-antispam 2.0+20120225-3 ii dovecot-core 1:2.1.7-7 ii dovecot-imapd 1:2.1.7-7 ii dovecot-ldap 1:2.1.7-7 ii dovecot-managesieved 1:2.1.7-7 ii dovecot-sieve 1:2.1.7-7 ii dovecot-solr 1:2.1.7-7

Re: [Dovecot] LDA vs. LMTP

The performance gains comes mostly from avoiding the overhead of invoking an executable and spawning a new process for each delivery.

[Dovecot] Case-insensitive "detail" mailboxes?
by /dev/rob0 27 Jul '13

27 Jul '13

We're using sieve with LMTP. We want to have lda_mailbox_autocreate and lmtp_save_to_detail_mailbox. Is there a way to make the "detail" case-insensitive? If so I have not found it yet. I suppose we could lowercase the input string for the SQL userdb query, but that's not what is wanted. The idea being that if a user makes a mailbox called "Test" is that user+test(a)example.com and user+TEST(a)example.com should both go to that "Test" mailbox. If it was lowercased, a mailbox called "Test" would be ignored and "test" used. With autocreate, this could be a problem if mail is delivered to autocreated case-sensitive mailboxes that the user won't see. Hmmm, maybe a global sieve script? -- http://rob0.nodns4.us/ -- system administration and consulting Offlist GMX mail is seen only if "/dev/rob0" is in the Subject:

[Dovecot] dbus support in dovecot?
by Gene Heskett 27 Jul '13

27 Jul '13

Greetings; I am trying to transition from ubu10.04.4 LTS to ubu12.04.2 LTS, but in the changeover I want to setup dovecot as a local only imap server so that I can read & respond to email from any of the other 4 or so machines on my local net. To that end, and given that I have a well working setup right now, using fetchmail driving mailfilter as a pre-check, procmail as the MTA delivering to /var/spool/mail/me, with clamav and spamd in the mix to intercept and send to /dev/null the worst of the spam, or to a quarantine file if clamav triggers. The current transfer mechanism is driven by a script that uses inotifywait to detect newly delivered mail in that directory, and which then sends kmail a dbus message to go get the mail. Since I want to insert dovecot into this chain, does dovecot have a dbus port, and if so, what is the format of the command it expects? Thanks all.

[Dovecot] Namespace, Sieve and upgrading to dovecot 2.0 -- no folder "INBOX/"
by Ben 27 Jul '13

27 Jul '13

I just upgraded from debian squeeze->wheezy. This meant upgrading from dovecot 1.2 to 2.1.7 and upgrading to Pigdeonhole sieve. I have dovecot configured to use sieve and virtual users (I'll post config below) Now any message that come in get filtered by sieve, but any messages that don't hit any filters gives the error (in the sieve log): msgid=<XXXX(a)XXX.com>: failed to store into mailbox 'INBOX/': Invalid mailbox name As far as I can tell, Pidgeonhole has hard-coded to the behavior of 'keep' (that is unfiltered emails) to be: fileinto "INBOX/" However, in my setup "INBOX/" is not a valid folder. "INBOX" is. Is there a way to get pidgeonhole sieve to treat 'keep' as fileinto "INBOX"? Or do I need to reconfigure my dovecot namespaces? I tried playing with them, but everything works right now (sharing, etc) and when I changed my prefix on the inbox, etc, it did weird things (INBOX.INBOX.FOLDER) instead of (INBOX.Folder). Suggestions? Here is, I believe the relevant config info: dovecot.conf: namespace { inbox = yes location = prefix = separator = / type = private } namespace { list = children location = maildir:/Mail/Users/%%n/:INDEX=/Mail/Users/%u/shared/%%u prefix = shared/%%u/ separator = / subscriptions = no type = shared } Thanks, Ben
