[Dovecot] mail_log_events, but who exactly triggered events?
by Arkadiusz Miśkiewicz 04 Feb '14

04 Feb '14

Hi. mail_log_events is nice addition but how to log who exactly triggered particular event? For example 5 users from 5 IP addresses uses single imap user/mailbox. One of them deletes email and I'm logging delete related events. The only logged thing is: dovecot: imap(user): delete: box=INBOX, uid=673287, msgid=<some@thing>, size=1230 which tells me nothing about who triggered it actually (note all 5 users were logged in at deletion time) How to solve this problem? Thanks, -- Arkadiusz Miśkiewicz, arekm / maven.pl

[Dovecot] zlib unexpected EOF
by Anand Kumria 04 Feb '14

04 Feb '14

Hi, I am seeing occasional log entries like: Feb 4 06:20:01 mail1 dovecot: imap(user(a)example.com): Error: read(<imap client>) failed: zlib.read(<imap client>): unexpected EOF at 894774 Feb 4 06:20:01 mail1 dovecot: imap(user(a)example.com): Disconnected in APPEND (1 msgs, 201 secs, 0/5180550 bytes) in=894774 out=643701 I've been able to correlate this to users - using Thunderbird - complaining that they have been unable to "send email". Is the problem on the Dovecot side, their side or something else? If on the Dovecot any pointers and what I should look at? Thanks, Anand

[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

[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.

[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.
