sieve_extprograms: how to filter original message twice?
by N0T3P4D 15 Jun '16

15 Jun '16

Hi, I use dovecot and sieve_extprograms to encrypt all incoming messages with the help of a Python script. Now, I want to process the _original_ message a second time. However, as expected, the second filter is applied to the already filtered message. For reference, here's a copy of the sieve script in question: if address :matches "To" "X(a)Y.Z" { fileinto "INBOX"; filter "gpgit.py" ["X(a)Y.Z", "--encrypt"]; fileinto "encrypted"; filter "gpgit.py" ["X(a)Y.Z", "--wrap"]; # Should be applied to the original message but uses the result of the first filter command fileinto "wrapped"; stop; } Does anyone have an idea how to modify the script to get the intended result? Please cc me, as I'm not subscribed. Thanks for your help Jeremias

Building Dovecot 2.2.24 GIT HEAD version
by Juan C. Blanco 15 Jun '16

15 Jun '16

Hello, I'm testing the last GIT (master-2.2) versión of dovecot 2.2 but I'm not able to build new rpm packages with our SPEC file on Centos 5.11. The problem seems to be with a new lib-dcrypt library, the file "src/lib-dcrypt/dcrypt-openssl.c" includes the file "openssl/ec.h" but the OpenSSL devel package included in Centos 5.11 is openssl-devel-0.9.8e-40.el5_11 that not contains the "openssl/ec.h" file I don't know if the next dovecot 2.2 release (derived from 2.2.24 GIT) will not be compatible with Centos 5.11 or if it will be necesary to install some optional openssl packages.

Upgrade to 2.2.9 breaks sasl auth
by Paul 15 Jun '16

15 Jun '16

Hi This is my 1st time here so please be gentle. I have encountered one problem since upgrading from 2.0.19 to 2.2.9 which has me beat. The system provides sasl auth services via inet to a postfix 2.11 system. Since the upgrade postfix complains of no sasl methods available. The same dovecot configuration is used on both versions. Now I get these results looking at the inet connection Version 2.0.19 root@larch:~# telnet 192.168.3.15 12345 Trying 192.168.3.15... Connected to 192.168.3.15. Escape character is '^]'.

Connected to 192.168.3.112. Escape character is '^]'. VERSION 1 1 SPID 5300 Seems be something lacking in the response from 2.2.9 that fits the "no sasl methods" response from postfix I believe I should supply root@larchvm:/etc/dovecot-sasl# dovecot -n -c dovecot.conf # 2.2.9: dovecot.conf # OS: Linux 3.13.0-88-generic i686 Ubuntu 14.04.4 LTS auth_mechanisms = plain login cram-md5 auth_verbose_passwords = plain base_dir = /var/run/dovecot-sasl/ disable_plaintext_auth = no instance_name = sasl mail_chroot = /chroot/mail mail_location = maildir:~/Maildir mail_plugins = quota managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacati on subaddress comparator-i;ascii-numeric relational regex imap4flags copy includ e variables body enotify environment mailbox date ihave namespace { inbox = yes location = prefix = INBOX. type = private } passdb { args = /etc/dovecot-sasl/dovecot-sqlmd5.conf driver = sql } plugin { deleted_to_trash_folder = Trash quota = maildir:User quota quota:noenforcing quota_rule = Trash:ignore sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } service auth { inet_listener auth-userdb { address = 192.168.3.112 port = 12345 ssl = yes } unix_listener /var/spool/postfix/private/auth { mode = 0666 } unix_listener auth-userdb { mode = 0600 } } service imap-login { inet_listener imap { address = 213.210.16.65 port = 143 } inet_listener imaps { address = 213.210.16.65 port = 993 ssl = yes } } service managesieve-login { inet_listener sieve { address = 213.210.16.65 port = 4190 } } ssl_cert = </etc/ssl/certs/pe.pem ssl_key = </etc/ssl/private/pe.pem userdb { args = /etc/dovecot-sasl/dovecot-sql.conf driver = sql } protocol imap { mail_plugins = quota imap_quota deleted_to_trash } Any help or suggestion warmly welcomed

shutdown_clients has no effect on doveadm stop
by Roland Rosenfeld 14 Jun '16

14 Jun '16

I try to restart dovecot 2.2.24 (for changing limits) without killing all IMAP and POP3 sessions. dovecot(1) tells me: When shutdown_clients is set to no, existing sessions will continue to use the old settings, after a dovecot reload. Also all sessions will keep alive after a dovecot stop. By default all active sessions will be shut down. According to my "dovecot -n" (see below), I have set "shutdown_clients=no", so "doveadm stop" should keep my open sessions. But if I try this out with a simple telnet to port 143 during "doveadm stop", I see the following: $ telnet imap 143 Connected to imap. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN AUTH=LOGIN] Dovecot ready. a login user(a)example.com XXXXX a OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS THREAD=ORDEREDSUBJECT MULTIAPPEND URL-PARTIAL CATENATE UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS BINARY MOVE QUOTA ACL RIGHTS=texk] Logged in * BYE Server shutting down. Connection closed by foreign host. The "BYE Server shutting down." happens exactly at the time, when I press return after "doveadm stop", "systemctl stop dovecot", or "systemctl restart dovecot" in the other shell. Only "systemctl reload dovecot" keeps the open sessions healthy. So it seems that either the man page is wrong, or shutdown_clients=no has no effect after dovecot stop...

Alternate Storage and quota limits
by mailing lists 14 Jun '16

Hi all, is there any way of exclude messages storaged in alternate storage (*dbox mailbox format) from being included in the quota usage? I think this is not possible but let me ask.

Advice on once a day message delivery setup
by KT Walrus 14 Jun '16

14 Jun '16

I’m adding once a day mail delivery to my site. Messages are marked by the sender as “overnight” or “once a week” delivery. The way I’m planning on implementing this is to queue messages until midnight in a MySQL database. Each mailbox will be kept in two Dovecot mailstores. The first mailstore will give the users IMAP access to their mailbox. A second mailstore will hold the next day’s new messages. At midnight, a cron job runs to send messages in the MySQL database out to the second mailstore. Then, at 6am, a second cron job will run to sync the two mailstores using doveadm sync. What I am expecting to happen is that during the day, notification messages (from the site) may be delivered to the first mailstore (the one providing IMAP access to the user) but no messages from other users sent during the day will come until after 6am the next day. Each time the user submits a new message, a notification message is sent back to the sender with a link for editing the queued message in the MySQL database and an indication of when it is scheduled for delivery. I am kind of assuming that the morning sync process is fast enough so it can easily complete before noon (in 6 hours) even if I end up having lots of mailboxes on each fully loaded Dovecot server. Is the doveadm sync process reliable and efficient enough for this type of “once a day” morning new message mail delivery? Or, should I just start delivering messages after midnight and not bother with the second mailstore and subsequent sync? Just looking for any advice… I kind of like the idea of modeling my mail service after the US Post Office where the mailman delivers new mail once a day rather than like Twitter/Facebook where messages are posted in real time to encourage users to monitor their boxes throughout the day.

doveadm-server protocol change?
by Heiko Schlittermann 13 Jun '16

Hi, I'm doing quota checks from a remote machine (the real setup is a bit more complex, if necessary I can explain it in more detail, but I just extracted the bits that are easily reproduceable) # nc backend1 24245 VERSION doveadm-server 1 0 PLAIN agrVMDvHgz0ya2HHzax5svwB2ZHS¹ + heiko quota get But since the backend is upgraded to 2.2.22 it's not possible anymore. The exuse in the log of the backend is: dovecot: doveadm(149.1.1.1¹): Fatal: USER environment is missing and -u option not used Running the `doveadm quota get -u heiko` locally on the backend works as expected.
