dict lookup from quota plugin
by Bjørnar Ness 23 Sep '15

23 Sep '15

I am having trouble with using a custom daemon listening on a socket together with the quota plugin. My configuration is: quota = dict:User quota::dict:/tmp/dovecot-proxy-dict:: The problem is that dovecot sends keys without usernames, for example: priv/quota/storage Is it possible to get around this limitation without code modification? Also, is it planned to support the "new-style" userdb/passdb lookups from other plugins? -- Bj(/)rnar

bug - over system quota and dovecot-uidlist
by krzf83＠gmail.com 23 Sep '15

23 Sep '15

Ever since I've migraded from courier pop3 to dovecot pop3 I'm constantly getting complains from users that went over system quota for short while and then their pop3 client downloads all messages again. I never happened with courier pop3. I think that dovecot does not handle dovecot-uidlist file safely so it can withstand such situations. rsync and other similar programs always writes to a copy of the file like dovecot-uidlis.xcb453 and on success unlinks old file and renames new one. Dovecot should not assume that write operation on dovecot-uidlist will succeed. Yes, I know I can put metadata like dovecot-uidlist somewhere else, on another partition but that really splits mailbox into multiple locations making for example backups way harder to make, restore, share etc.

Dovecot proxy ignores trusted root certificate store
by Alex Bulan 22 Sep '15

22 Sep '15

Dovecot v2.2.18 OS: FreeBSD 10.1/amd64 Dovecot in proxy mode ignores the root certificate store and can't verify the backend's SSL certificate. I've pointed ssl_client_ca_file to my root certificate store, but I suspect ssl_client_ca_file is only used in imapc context. It seems to be ignored in proxy context. doveconf -n ssl_client_ca_file: ssl_client_ca_file = /usr/local/share/certs/ca-root-nss.crt In my password_query I return host set to the backend's IP address, starttls='yes', proxy='y'. The backend's certificate chain is correct and it verifies successfully with "openssl s_client -connect x.x.x.x:110 -starttls pop3 -CAfile /usr/local/share/certs/ca-root-nss.crt". But the Dovecot proxy fails to verify the intermediate certificate it receives from the backend. The inode atime of ca-root-nss.crt is never updated, either at Dovecot start or when it connects to the backend, so Dovecot (via the openssl library) never reads the file.

2.2.18 Regression: Incorrect STATUS response for virtual mailboxes
by Guilhem Moulin 22 Sep '15

22 Sep '15

As shown below, adding a message to TRASH doesn't increase virtual/test's MESSAGES count. However SELECTing virtual/test triggers the increase; so does running `doveadm mailbox status vsize virtual/test` in another shell. $ mkdir -m0700 ~/mail/virtual/test $ echo -e "TRASH\n\tall" > ~/mail/virtual/test/dovecot-virtual $ /usr/lib/dovecot/imap S: * PREAUTH [CAPABILITY IMAP4rev1 … ] Logged in as guilhem C: a STATUS TRASH (MESSAGES UIDNEXT UNSEEN) C: b STATUS virtual/test (MESSAGES UIDNEXT UNSEEN) S: * STATUS TRASH (MESSAGES 5599 UIDNEXT 5619 UNSEEN 0) S: a OK Status completed (0.001 secs). S: * STATUS virtual/test (MESSAGES 5599 UIDNEXT 5600 UNSEEN 0) S: b OK Status completed (0.032 secs). C: c APPEND TRASH {1+} S: x S: c OK [APPENDUID 1442277584 5619] Append completed (0.029 secs). C: d STATUS TRASH (MESSAGES UIDNEXT UNSEEN) C: e STATUS virtual/test (MESSAGES UIDNEXT UNSEEN) S: * STATUS TRASH (MESSAGES 5600 UIDNEXT 5620 UNSEEN 1) S: d OK Status completed (0.000 secs). S: * STATUS virtual/test (MESSAGES 5599 UIDNEXT 5600 UNSEEN 0) S: e OK Status completed (0.000 secs). # it doesn't help to LOGOUT and issue the STATUS command again. However, # it does to execute `doveadm mailbox status vsize virtual/test` in another # shell, or to SELECT virtual/test in the IMAP session. C: f STATUS TRASH (MESSAGES UIDNEXT UNSEEN) C: g STATUS virtual/test (MESSAGES UIDNEXT UNSEEN) S: * STATUS TRASH (MESSAGES 5600 UIDNEXT 5620 UNSEEN 1) S: f OK Status completed (0.000 secs).

sieve_extprograms - run any individual script?
by Hajo Locke 22 Sep '15

22 Sep '15

Hello, i use sieve extension sieve_extprograms to send incoming mail to some script. For security reasons it is needed that script-paths etc. are registered in dovecot.conf This is my current dovecot.conf plugin { sieve = ~/.dovecot.sieve sieve_plugins = sieve_extprograms sieve_extensions = +vnd.dovecot.pipe +vnd.dovecot.filter +vnd.dovecot.execute sieve_pipe_bin_dir = /usr/local/bin/ sieve_filter_bin_dir = /usr/local/bin/ } .dovecot.sieve example: if address "to" "test(a)example.com" { filter "myfilter"; } This is all working without problems. Is there a possibility to allow users the execution of individual scripts in own homepath? Some people need to pipe mails to scripts for immediately processing (some ticketsystems need this). Is there a way to make this possible with sieve? Thanks, Hajo

Multiple passwords for a user (SQL)
by Marco Fretz 21 Sep '15

21 Sep '15

Hi everyone, I'm not sure if this has been discuessed already as I coun't find anything in the archives - maybe I'm looking for the wrong thing. I want to build something similar to googles "app passwords" where your use a different password (strong, auto generated) for each device / app. In general I think this is pretty easy on the database side as I just need a password table and link say the passwords with an user_id to the corresponding user in the users table - one use has many passwords (1:n). for dovecot this means that it will get multiple rows with passwords back from the "password_query". is there a way to tell dovecot to check all those returned passwords and "pass" the request if one of those passwords match? thank you, best regards Marco

[Dovecot] Pigeonhole sieve re-filter extension?
by T.B. 21 Sep '15

21 Sep '15

Dear Stephan Bosch, dear Dovecot community, "sieve-filter" re-filtering of existing mails is already a great progress for everyone using sieve! But as far as I know this functionality is just accessible by the server administrator. In the meanwhile everyone knows the comfort of re-executing filter scripts on his own existing mailboxes - triggered by himself! This service is already very widespread. Examples are MUA's like Outlook or Thunderbird which provide this service just on the client side. Or almost every web-mail provider offers this. Is there already an managesieve protocol extension that allows client triggered server side re-filtering? If not, maybe you could design a RFC for this? What do you think? Best regards. T.B.

ssl_key_password loaded from file: 'Couldn't parse private ssl_key'
by B. R. 21 Sep '15

21 Sep '15

As this is my first message to this ML: Hello! I am using a password-protected SSL key for my dovecot MDA. When I tried to use the ssl_key_password configuration directive as follow: ssl_key_password = </path/to/passfile it did not work as I logged the following: dovecot: imap-login: Error: SSL: Stacked error: error:06065064:digital envelope routines:EVP_DecryptFinal_ex:bad decrypt dovecot: imap-login: Fatal: Couldn't parse private ssl_key: error:0906A065:PEM routines:PEM_do_header:bad decrypt However, not using the fille inclusion but directly configuring as follow: ssl_key_password = mypass did work... I am loading my certificate & key with the file inclusion trick... How come cannot I use that for the password file? It would avoid input the password directly into the dovecot configuraiton files, forcing me to change permissions and duplicating it... When renewing the private key I will be force to edit the password at every location. Is it a bug? or a feature? :D --- *B. R.*

Messages lost from imap folders
by Nikolaos Milas 19 Sep '15

19 Sep '15

Hello, We have one user who is complaining that he has lost mails from 3 imap folders, administered through squirrelmail. The folders suddenly appeared unregistered, and once manually registered they were empty. Has anyone observed something like this? We are running two servers (as VMs) with Dovecot v2.2.18, synced (two-way) using dsync. The configurations follow. Can you please help me understand what may have gone wrong? Can I try to find actions regarding these folders in the logs? What should I search for? Could this be an issue involving dsync? How can I trace back dsync activity in detail? Server configs follow (I have only altered the real domain name and the login greeting.)
