[Dovecot] Dovecot versions and index compatibility
by Steven F Siirila 22 Sep '09

22 Sep '09

I realize these are older versions, but I'd like to know specifically whether dovecot 1.1.6 and dovecot 1.1.8 are compatible index-wise. In particular, if we downgraded from 1.1.8 to 1.1.6 would there be any issues with doing so? I realize there are later versions, but we've tested both of the above extensively, but recently loaded up a server with 1.1.8 and found that the 'imap' process core dumps frequently, so before we pursue later versions we thought it would be best to downgrade to 1.1.6. -- Steven F.

[Dovecot] Managesieve displays folder name (dovecot/sieve)
by Seba 21 Sep '09

21 Sep '09

Hi, I'm using Dovecot 1.2.4 with ManageSieve 0.11.9 and Sieve. All works fine but users can subscribe to the folder "dovecot/sieve" which is also displayed in the folders list. protocols = imap managesieve protocol managesieve { listen = ip_address:2000 managesieve_logout_format = bytes ( in=%i : out=%o ) } plugin { sieve=~/Maildir/.dovecot.sieve sieve_dir=/home/vmail/%d/%n/Maildir } In the maildir of the user I see this folders and files: .Drafts/ .Sent cur/ new/ temp/ sieve/ @.dovecot.sieve ingo.sieve The file "ingo.sieve" comes from Horde Ingo because users manage their scripts with ingo.The symlink "dovecot.sieve" is correct and point to ingo.sieve. When users browse their available IMAP folders they'll see a folder "dovecot/sieve". Can this be turned off or restricted with acl's? Without an symlink all folders are displayed normally without the "dovecot sieve" folder. Thanks.

[Dovecot] Maildir quota reporting
by David Kmoch 21 Sep '09

21 Sep '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I'm little confused with the way dovecot (1.2.4) is reporting quota. with this config protocols: imaps ssl: required ssl_ca_file: /root/cert/CA_Bundle_Trans.crt ssl_cert_file: /root/cert/mails.crt ssl_key_file: /root/cert/mails-key.pem.rsa disable_plaintext_auth: yes login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login mail_location: maildir:%h/Maildir mail_debug: yes mail_plugins: quota imap_quota lda: postmaster_address: postmaster(a)example.com mail_plugins: quota cmusieve mail_plugin_dir: /usr/lib/dovecot/lda auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd plugin: quota: maildir:User quota quota_rule: ?:storage=20G sieve: ~/.dovecot.sieve everything works fine. TB says, there 20G quota. Command echo "1 GETQUOTAROOT INBOX" | USER=foo dovecot --exec-mail imap reports * QUOTAROOT "INBOX" "User quota" * QUOTA "User quota" (STORAGE 0 20971520) 1 OK Getquotaroot completed. Now I change the first line in foo's maildirsize file to "0S" to allow unlimited quota. Then I boost it's size to force recalculation (just to be sure) dd if=/dev/zero bs=1k count=6 >> ~foo/Maildir/maildirsize - From now, TB still reports 20GB quota for user foo, the above "echo" command still reports 20971520, but(!), quota is actually unlimited for user foo. OK, now I stop dovecot, delete maildirsize, change line in dovecot.conf quota_rule = ?:storage=0 and start dovecot again. The same result - TB still reports 20GB quota for user foo, the above "echo" command still reports 20971520, but(!), quota is actually unlimited for anyone. When I set some limit in ~foo/Maildir/maildirsize now, same values 20971520) are reported, although the limit works! Looks like LDA (deliver) works fine, but imap_quota plugin is doing something weird. Finally, the question ;-) Where does that value (20971520) come from? Is it a feature or a bug? - -- David Kmoch -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkqfhQoACgkQsUUM+N2AWobj7ACgh3yCU9LVfe1Pp2lO0nBG9iKf zbgAn15UvkVM0AeCxaUlDeYgFu++8TOn =CAoG -----END PGP SIGNATURE-----

[Dovecot] plugin development guide for non-FS backing store
by Chang Song 21 Sep '09

21 Sep '09

Hi, folks. I was wondering if anyone has some sort of guide or reference on plugin development. We are trying to develop a non-filesystem backing store. So basically we do not store mailboxes for users in local filesystem. We do RPC call to fetch from fileservers. Thank you in advance. Chang

[Dovecot] Override quota rules based on mail's content
by Andreas Calvo Gómez 21 Sep '09

21 Sep '09

Hi, I've a mail server with Postfix and Dovecot, using a LDAP backend to get the users. I've also configure quota rules, and I'm able to get the quota from LDAP. But I need the mails that come from the local domain to bypass the quota rule and be delivered to the users' inbox. Is there any way to do that? Information required by Dovecot's mailing list rules: +++ dovecot.conf +++ # 1.1.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.28-15-server x86_64 Ubuntu 9.04 ext4 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_user: postfix valid_chroot_dirs: /var/spool/dovecot first_valid_uid: 1000 first_valid_gid: 512 mail_privileged_group: mail mail_location: maildir:/var/spool/dovecot/%n/ mail_plugins: quota imap_quota imap_client_workarounds: delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep auth default: mechanisms: plain login default_realm: esci.es username_format: %Lu passdb: driver: pam passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: prefetch userdb: driver: passwd userdb: driver: ldap args: /etc/dovecot/dovecot-ldap-userdb.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: mail group: mail plugin: quota: maildir:User quota quota_rule: *:storage=50M quota_rule2: Trash:ignore +++ dovecot-ldap.conf +++ hosts = ldap.esci.es auth_bind = yes ldap_version = 3 base = ou=Users, dc=esci, dc=es scope = subtree user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid,mailQuota=quota_rule=*:storage=%$M user_filter = (&(objectClass=posixAccount)(|(mail=%u)(uid=%u)(uid=%n))) pass_attrs = uid=user,userPassword=password,\ homeDirectory=userdb_home,uidNumber=userdb_uid,gidNumber=userdb_gid,mailQuota=userdb_quota_rule=*:storage=%$M pass_filter = (&(objectClass=posixAccount)(|(mail=%u)(uid=%u))) default_pass_scheme = SSHA Thanks. --------------------- Andreas Calvo Gómez <andreas.calvo(a)admi.esci.es> Dept.

[Dovecot] Automatic fd limit changing
by Timo Sirainen 21 Sep '09

21 Sep '09

I just realized that Dovecot should probably be doing something different with how it handles fd limits. The way it currently works is: 1. It checks some settings and warns at startup if fd limit is lower than what master process might need. 2. For login processes it calculates how many fds are needed and then either increases or decreases it. So it's automatically and silently increasing fd limit for some processes, but not for others. Should it just automatically increase the limits to all processes when necessary, or never increase and just warn that the limit is too low?

[Dovecot] Sieve not fast enough after upgrade?
by Nikolay Shopik 21 Sep '09

21 Sep '09

I've upgraded mine Dovecot 1.0.15 to 1.2.4 also moved to new Sieve. I have simple sieve rule: if header :contains "Delivered-To" ["bcc(a)bcc.inblock.ru"] { setflag "\\Seen"; } It basically mark my own messages which are saved to Sent folder. When I was on 1.0.15 I never seen unread count in Thunderbird, but suddenly after upgrade I seen unread message in Sent folder just after I've sent message. If I open Sent folder it already marked as read. Me wonder if this is actually Dovecot much faster delivers and reports to MUA there is new unread message or Sieve not perform fast enough?

[Dovecot] Dovecot Sieve Vacation Messages
by Steven Murphy 20 Sep '09

20 Sep '09

I'm using a Postfix, Dovecot, MySQL setup with virtual domains. I have mail being delivered through Dovecot LDA working 100%. I'm trying to use sieve to handle vacation messages but dovecot is not reading the .dovecot.sieve file in the users maildir. I have a hunch it has to do with my dovecot-sql query but have had no success with what I found in the forums from Googling. Any help would be greatly appreciated.
