[Dovecot] Dovecot2 + Quota
by drum.lucas＠gmail.com 04 Feb '14

04 Feb '14

Hello! I need to configure Quota on Roundcubemail with Dovecot2. So, I did: 90-quota.conf: # SQL backend: quota = dict:User quota::proxy::sqlquota quota_rule = *:storage=20M:messages=1000 } dict { sqlquota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } OK, works! but, My webmail shows me 20M of quota. But on my Postfixadmin I configured 200M. How can I fix this? Att; *Lucas Possamai* http://about.me/lucaspossamai https://www.digitalocean.com/?refcode=25021cb7dbdf

Is there any way to control/disable this for certain mailboxes? For one account (that handles bounces) I need it disabled, for all the other (normal) accounts its great. -- Andrew Ray

[Dovecot] Assertion failed with imapc after upgrading Dovecot from 2.1.7 to 2.2.9
by Sylvain 29 Jan '14

29 Jan '14

Hi ! I have an old Courier IMAP and in front of it, I have put a proxy cache with Dovecot/imapc. I use Debian Wheezy (stable) which package Dovecot in version 2.1.7. I have tested the upgrade to Debian Jessie (testing) which package Dovecot in version 2.2.9 but an assertion is thrown : dovecot: imap(xxx): Panic: file imapc-list.c: line 499 (imapc_list_delete_unused_indexes): assertion failed: (strncmp(vname, fs_list->ns->prefix, fs_list->ns->prefix_len) == 0) I have checked source code and have seen that if *imapc_list_prefix* is not set, assertion will not be "walked". It's works but special inbox aren't detected correctly in email clients. If I understand the meaning of *vname* variable, it is because our Courier IMAP send us "INBOX" which is the value of my *imapc_list_prefix* and thus, assertion is thrown. Here some details of my tests : Courier IMAP : * OK [CAPABILITY IMAP4rev1 UIDPLUS CHILDREN NAMESPACE THREAD=ORDEREDSUBJECT THREAD=REFERENCES SORT QUOTA IDLE ACL ACL2=UNION STARTTLS] Courier-IMAP ready.

[Dovecot] Shared mailbox ACL
by Alex Ferrara 29 Jan '14

29 Jan '14

Hi everyone, I am having some trouble with shared folders in trying to replicate how we use them with a Cyrus backend. The auth database is Samba4 active directory, so I am using an LDAP lookup to authenticate and forcing the UID and GID to be all the same. I have a post-login script that sets the group ACL, and this seems to be working fine. /mnt/mail is an NFS mount to a FreeNAS machine, and there is only one Dovecot server connecting to that NFS share. I have been able to get the inbox of the shared mailbox to appear in Thunderbird, but I would like to allow all subfolders to have the same ACLs. Is there a way to do this without having an ACL entry for each folder in the dovecot-acl file? I also cannot seem to create folders under the shared inbox. Thanks. Below is the output of /mnt/mail/acl/shared-mailboxes shared/shared-boxes/group/accounting/accounting 1 shared/shared-boxes/group/team1/team1 1 shared/shared-boxes/group/team2/team2 1 Below is the output of dovecot -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-22-pve x86_64 Debian 7.3 nfs auth_mechanisms = plain login auth_username_format = %n mail_debug = yes mail_location = maildir:/mnt/mail/mailboxes/%n/Maildir:INDEX=/var/local/dovecot-indexes/%n mail_plugins = acl 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 namespace { list = yes location = maildir:/mnt/mail/mailboxes/%%n/Maildir:INDEX=/var/local/dovecot-shared/%%n prefix = ZGroup/%%n/ separator = / subscriptions = no type = shared } namespace inbox { inbox = yes location = 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 = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { acl = vfile acl_defaults_from_inbox = yes acl_shared_dict = file:/mnt/mail/acl/shared-mailboxes sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = " imap lmtp sieve" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } service imap-postlogin { executable = script-login /usr/local/bin/postlogin.py user = vmail } service imap { executable = imap imap-postlogin } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } user = vmail } ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocol lmtp { mail_plugins = quota sieve } protocol lda { mail_plugins = quota sieve } protocol imap { mail_plugins = acl imap_acl }

Oh yes, that's right. I confused maildir format with sendmail queue files that separates header and body. There is still some similarlity for mass mailouts to the same mail domain: they will have almost identical headers +/- message IDs and a few bytes here and there, but as you say, SiS is the way to go for deduping bulky message attachments.

[Dovecot] recipient_delimiter -- feature request
by Andrew Ray 29 Jan '14

29 Jan '14

Hi, It would be nice if the recipient_delimiter configuration option supported multiple recipient delimiters as Postfix now does. e.g. now if I set: recipient_delimiter = +- in Postfix, then test-extension(a)sample.com and test+extension(a)sample.com are both recognized. But if I set: recipient_delimiter = +- in Dovecot, neither of the above are recognized and instead test+-extension(a)sample.com is valid. Well, presently this feature isn't that important to me, but I imagine it could be a source of confusion for people who are migrating from say qmail to postfix (as I am doing) and notice Postfix's cool ability to support both types of delimiters and assume Dovecot will as well (as I did). Thanks, Andrew Ray -- Andrew Ray +1 404-418-5443 +421 (0) 917 832 253 http://guns.freedomlives.net/

[Dovecot] post-login scripting failing with "denied access to user" v2.1.7
by Frank 29 Jan '14

29 Jan '14

I am trying to have a default sieve rule for new mailboxes that can be edited by users using the round cube sieve plugin. It would actually be better executed when a new user is created but my postfixadmin runs on a separate machine so that's a bit tricky. The "sieve-default =" setting won't quite achieve what I want as I want users to be able to edit the default rule (to adjust SPAM level) Mail works fine before I add my post-login script to 10-master.conf ---------------------- service imap { # tell imap to do post-login lookup using a socket called "imap-postlogin" executable = imap imap-postlogin } service imap-postlogin { # all post-login scripts are executed via script-login binary executable = script-login /etc/dovecot/custom_sieve/postlogin.sh # the script process runs as the user specified here (v2.0.14+): user = mail # also tried $default_internal_user and root # this UNIX socket listener must use the same name as given to imap executable unix_listener imap-postlogin { } } After adding this setting, login fails and gives the error below. It certainly looks like a permission issue, but I have checked my script is executable and owned by vmail:vmail. The bash script executes fine as the mail user. The other possibility is that dovecot is denying access to the $HOME variable, but that seems unlikely. Nevertheless, I am stuck!

Just a guess, but I expect the difference is because NetApp de-dupes by checksumming blocks and mark whole blocks as duplicates if they have the same checksum. The message body has the same block offset in maildir (i.e. the start of a message is at byte 0), whereas mdbox might align message body anywhere in a block, so you might have 512 different block configurations for the same message. I don't know whether message alignment would be a worthwhile optimization for mdbox. Joseph Tam <jtam.home(a)gmail.com>
