Understanding quotas
by Robert Moskowitz 23 Mar '17

23 Mar '17

Just to level-set, I am using Centos7-arm which supplies Dovecot 2.2.10. I don't have access to a arm build or mock environment and use what is available (I DID try to install them but had dependency issues). Much of what I have is from campworld, but some I have picked up from other Centos mailserver builders. Also I am using Postfixadmin which provides quotas per user in mysql database. To access those quotas for dovecot, I have the following script: cat <<EOF>/etc/dovecot/dovecot-dict-quota.conf || exit 1 connect = host=localhost dbname=postfix user=postfix password=$Postfix_Database_Password map { pattern = priv/quota/storage table = quota2 username_field = username value_field = bytes } map { pattern = priv/quota/messages table = quota2 username_field = username value_field = messages } EOF Where $Postfix_Database_Password is an env variable in my install howto. I am setting up quota plugins as follows: sed -i "/#mail_plugins/ a mail_plugins = quota sieve" /etc/dovecot/conf.d/15-lda.conf sed -i "/#mail_plugins / a mail_plugins = quota imap_quota trash" /etc/dovecot/conf.d/20-imap.conf sed -i "/#mail_plugins/ a mail_plugins = quota" /etc/dovecot/conf.d/20-pop3.conf But I am having 'challenges' with how to actually enable quotas and understanding 90-quota.conf. I am starting from campworld's 'reduced' dovecot.conf seeing: dict { quotadict = mysql:/etc/dovecot/dovecot-dict-quota.conf } and plugin { quota = dict:user::proxy::quotadict acl = vfile:/etc/dovecot/acls trash = /etc/dovecot/trash.conf sieve_global_path = /home/sieve/globalfilter.sieve sieve = ~/dovecot.sieve sieve_dir = ~/sieve sieve_global_dir = /home/sieve/ #sieve_extensions = +notify +imapflags sieve_max_script_size = 1M } I have put the sieve plugin lines into the 90-sieve.conf and the acl into 10-acl.conf. Trash is a separate matter for a later question... So I am looking for guidance as to how to integrate the Postfixadmin quota information properly into 90-quota.conf thank you

Permission denied when logrotating dovecot.log

Hello guys Having headaches here how to make logrotation for dovecot log files work. Having permission issues: michael.heuberger@xxx /e/l/daily ❯❯❯ sudo logrotate -fv dovecot.daily ⏎ reading config file dovecot.daily Handling 1 logs rotating pattern: /var/log/dovecot*.log forced from command line (10 rotations) empty log files are rotated, old logs are removed considering log /var/log/dovecot.log error: skipping "/var/log/dovecot.log" because parent directory has insecure permissions (It's world writable or writable by group which is not "root") Set "su" directive in config file to tell logrotate which user/group should be used for rotation.

SIS and mailbox restore
by Jean-Luc Oms 22 Mar '17

22 Mar '17

Still on the problem with dovecot 2.2.27 .... I use the single instance storage, and mdbox format. I use 2 zfs file systems, one for mailboxes, the other for attachements. I use znapzend to generate many zfs snapshots for backup purpose (inode numbers are preserved but it is unusefull). When I try to restore a deleted/purged mailbox with doveadm import I get the error of the first attachement missing in the SIS and the process stops. Option 1: the python script is working but it's really too long. * I restore all the SIS missing files since the snapshot date, preserving hard link count; * I restore the mailbox * I purge all the mailbox to delete the large number of unnecessery files restored Option 2: looking in the list archive I see that doveadm dump can guive me the msg.ext-ref that was missing to my knowledge. I try this use of doveadm dump: doveadm dump /MySnapShot/vmail/user/mdbox/storage/m.* Is this correct to get all the information I need ? I have to write a script to get msg.ext-ref for a particular msf.guid, or a specific mailbox Is there a way with doveadm dump to extract this type of information for a particular mailbox ? Thanks for your support. -- __________________________________________ Jean-Luc Oms STI-RéseauX - LIRMM - CNRS/UM2 161 rue Ada - BAT 4 - CC 477 34095 Montpellier cedex 5 Tel +33 4 67 41 85 93 Urg +33 6 32 01 04 17 __________________________________________

[Sieve] Is the way to run external script to get attachment?
by Konstantin Shalygin 22 Mar '17

22 Mar '17

Hello. Read all about Extprograms, but have a question. Use case: Every day we have couple messages with attachment (from one sender, this is one-way communication). This attachment is uploads to ownCloud. By hand... need some automation. As I see, pipe cat execute scripts with text data USER/FROM/SUBJECT - and I think with variables it can be any text data, how about attachment? How I see this: script executes and as arg receives from sieve attachment file, or message file and we can parse it for attachment. When we have attachment - upload to ownCloud via RESTapi and purge message. Found some realization for encrypt messages https://github.com/EtiennePerot/gpgit/blob/master/encmaildir.sh but for me more easy just connect to IMAP and do what I want (but I love sieve). Thanks. <http://wiki.dovecot.org/Pigeonhole/Sieve/Plugins/Extprograms>

Problem with sieve_before
by Ger Hooton Scoil Chroí Íosa Blarney 22 Mar '17

22 Mar '17

Hi All, I cannot get the sieve_before to work. I have dovecot & sieve installed on Debian 7 as follows /etc/dovecot/conf.d/90-sieve.conf : plugin { # The path to the user's main active script. If ManageSieve is used, this the # location of the symbolic link controlled by ManageSieve. sieve = ~/.dovecot.sieve # The default Sieve script when the user has none. This is a path to a global # sieve script file, which gets executed ONLY if user's private Sieve script # doesn't exist. Be sure to pre-compile this script manually using the sievec # command line tool. # --> See sieve_before fore executing scripts before the user's personal # script. sieve_default = /var/lib/dovecot/sieve/default.sieve # Directory for :personal include scripts for the include extension. This # is also where the ManageSieve service stores the user's scripts. sieve_dir = ~/sieve/ # Directory for :global include scripts for the include extension. sieve_global_dir = /var/lib/dovecot/sieve/ # Path to a script file or a directory containing script files that need to be # executed before the user's script. If the path points to a directory, all # the Sieve scripts contained therein (with the proper .sieve extension) are # executed. The order of execution within a directory is determined by the # file names, using a normal 8bit per-character comparison. Multiple script # file or directory paths can be specified by appending an increasing number. sieve_before = /var/lib/dovecot/sieve/before #####sieve_before2 = /var/lib/dovecot/sieve/before/default2.sieve #sieve_before3 = (etc...) # Identical to sieve_before, only the specified scripts are executed after the # user's script (only when keep is still in effect!). Multiple script file or # directory paths can be specified by appending an increasing number. #sieve_after = #sieve_after2 = #sieve_after2 = (etc...) # Which Sieve language extensions are available to users. By default, all # supported extensions are available, except for deprecated extensions or # those that are still under development. Some system administrators may want # to disable certain Sieve extensions or enable those that are not available # by default. This setting can use '+' and '-' to specify differences relative # to the default. For example `sieve_extensions = +imapflags' will enable the # deprecated imapflags extension in addition to all extensions were already # enabled by default. #sieve_extensions = +notify +imapflags .................................

dovecot POP3 log shows too many identical RETR entries
by Bappasaheb Nirmal 22 Mar '17

22 Mar '17

Hello, Dovecot log is showing too many POP3 RETR entries which are identical lines. I also suspect that it is causing high pop traffic eating most of the network bandwidth. Here are some of the lines out of 11009 in a day. Such pattern is observed only for few users. dovecot version is 2.1.17. ============== Mar 20 00:00:07 pi3 dovecot: pop3(user(a)example.com): Disconnected: Logged out top=0/0, retr=1/64014, del=0/1429, size=478762716 Mar 20 00:00:07 pi3 dovecot: pop3-login: Login: user=<user(a)example.com>, method=PLAIN, rip=43.243.173.97, lip=192.168.1.18, mpid=26645, secured, session=<5CGrmRlLyAAr861h> Mar 20 00:00:10 pi3 dovecot: pop3(user(a)example.com): Disconnected: Logged out top=0/0, retr=1/64014, del=0/1429, size=478762716 Mar 20 00:00:11 pi3 dovecot: pop3-login: Login: user=<user(a)example.com>, method=PLAIN, rip=43.243.173.97, lip=192.168.1.18, mpid=29932, secured, session=<k6/gmRlL3gAr861h> Mar 20 00:00:12 pi3 dovecot: pop3(user(a)example.com): Disconnected: Logged out top=0/0, retr=1/64014, del=0/1429, size=478762716 Mar 20 00:00:13 pi3 dovecot: pop3-login: Login: user=<user(a)example.com>, method=PLAIN, rip=43.243.173.97, lip=192.168.1.18, mpid=26819, secured, session=<3DX6mRlLUQAr861h> Mar 20 00:00:14 pi3 dovecot: pop3(user(a)example.com): Disconnected: Logged out top=0/0, retr=1/64014, del=0/1429, size=478762716 Mar 20 00:00:15 pi3 dovecot: pop3-login: Login: user=<user(a)example.com>, method=PLAIN, rip=43.243.173.97, lip=192.168.1.18, mpid=9636, secured, session=<x5ghmhlLjwAr861h> Mar 20 00:00:16 pi3 dovecot: pop3(user(a)example.com): Disconnected: Logged out top=0/0, retr=1/64014, del=0/1429, size=478762716 Mar 20 00:00:17 pi3 dovecot: pop3-login: Login: user=<user(a)example.com>, method=PLAIN, rip=43.243.173.97, lip=192.168.1.18, mpid=4585, secured, session=<8Yw+mhlL0AAr861h> Mar 20 00:00:18 pi3 dovecot: pop3(user(a)example.com): Disconnected: Logged out top=0/0, retr=1/64014, del=0/1429, size=478762716 Mar 20 00:00:18 pi3 dovecot: pop3-login: Login: user=<user(a)example.com>, method=PLAIN, rip=43.243.173.97, lip=192.168.1.18, mpid=30049, secured, session=<UsJOmhlLmAAr861h> Mar 20 00:00:19 pi3 dovecot: pop3(user(a)example.com): Disconnected: Logged out top=0/0, retr=1/64014, del=0/1429, size=478762716 Mar 20 00:00:20 pi3 dovecot: pop3-login: Login: user=<user(a)example.com>, method=PLAIN, rip=43.243.173.97, lip=192.168.1.18, mpid=9636, secured, session=<B6VimhlLNgAr861h> Mar 20 00:00:20 pi3 dovecot: pop3(user(a)example.com): Disconnected: Logged out top=0/0, retr=1/64014, del=0/1429, size=478762716 Mar 20 00:00:20 pi3 dovecot: pop3-login: Login: user=<user(a)example.com>, method=PLAIN, rip=43.243.173.97, lip=192.168.1.18, mpid=4584, secured, session=<pVpxmhlLPwAr861h> Mar 20 00:00:21 pi3 dovecot: pop3(user(a)example.com): Disconnected: Logged out top=0/0, retr=1/64014, del=0/1429, size=478762716 Mar 20 00:00:23 pi3 dovecot: pop3-login: Login: user=<user(a)example.com>, method=PLAIN, rip=43.243.173.97, lip=192.168.1.18, mpid=4585, secured, session=<MlGam ============== What could be the possible reason?
