[Dovecot] Deleting metadata smashes file dovecot.dict
by Andre Gröbe 28 Aug '12

28 Aug '12

Hi, I am using dovecot (see dovecot -n output below) with metadata plugin in my own plugin. I want to insert and delete some large metadata (>4KiB). It seems, that the delete in a second call of my plugin smashes the file dovecot.dict in users dir: 1st call: *dovecot.dict is empty -delete metadata 1 -delete metadata 2 -insert metadata 1 ~8KiB -insert metadata 2 <1KiB *dovecot.dict contains two entries 2nd call: -delete metadata 1 -delete metadata 2 -insert metadata 1 ~8KiB -insert metadata 2 <1KiB *dovecot.dict contains the two entries + some waste If all eight steps are called together (in the same plugin context) the file dovecot.dict seems to be ok. I have created a test plugin to reproduce this behaviour: <http://temp-share.com/show/dPf3myu5W>. It needs the notify and (patched) metadata plugin to run. To get it work i copy an email from one IMAP folder to another (to trigger the copy notifier). It seems, that there is an issue on writing metadata/dict, can anybody reproduce it or knows what is wrong? TIA -- Andre

[Dovecot] Sieve/pigeonhole rejects email addresses for valid UNIX users
by David Anderson 28 Aug '12

28 Aug '12

Self-explanatory, I hope (note the period on the end of the username); sieve/pigeonhole does not allow you to have senders which end with a period, which means that any UNIX users with such usernames who send mail have it rejected by sieve: # useradd testuser. # su - testuser. $ mail david(a)example.com -s 'testing' 123 . [testuser.@levi ~]$ logout # less /var/log/maillog Aug 22 07:50:56 levi dovecot: lda(david(a)example.com): Error: sieve: envelope sender address 'testuser.(a)myhost.example.com' is unparsable Versions: dovecot-pigeonhole-0.2.6-21.el5 dovecot-managesieve-0.2.6-21.el5 dovecot-2.0.18-1_134.el5 Why would anyone have a UNIX username ending in a period? For one, web hosting companies may use your domain name as your username - but be subject to a 32-character limit, so your domain name gets truncated.

[Dovecot] use sieve plugin with variable and folders
by Alano Conraz 28 Aug '12

28 Aug '12

Hello , I'm trying to use the pigeonhole plugin but I'm experiencing configuration problem... Hope you could help me! Firstly : my sieve filter test is the next one : /////////////////// require ["fileinto" , "variables" , "mailbox"]; if address :matches "Delivered-To" "*(a)*.*" { fileinto :create ".INBOX.iop" ; stop ; } //////////////////// I get in the log the following : "error: msgid=<****>: failed to store into mailbox '.INBOX.iop': Invalid mailbox name" And the email is stored in the INBOX (implicit keep was successful) I checked that "lda_mailbox_autocreate" and "lda_mailbox_autosubscribre" are set to "yes". Then , when this problem be solved, I would like to know if it is possible with the sieve plugin to implement the following algorithm : - extract the address from the header field "Delivered-To" and set the variable $delivto to this previous value. - extract the address from the header field "To" and set the variable $to to this previous value. - compare $delivto and $to : if they are diffrent, then redirect the email in the subfolder .INBOX.iop. Thank you for any help!

[Dovecot] plugin development: retrieve username -d -f inside plugins
by Alano Conraz 27 Aug '12

27 Aug '12

Hello, i don't know if it a the right place to ask my question related to the development of dovecot plugins, please correct me if it is not. I'm trying some dovecot plugin development. I did a little plugin that suit my needs but i'd like to go further now... I would like to know if there is a kind of "getenv" function that I could call to retrieve in my plugin the username of the mailbox being delivered by dovecot-lda or served by imap server. For example, when I use the deliver with "cat file.txt | deliver -d " user(a)domain.net" -f "me(a)domain.net" I would like to call a function that could return for me the argument of "-d" or "-f". i'm working with dovecot 2.0.17 by now. Thank you

[Dovecot] How to configure dovecot for specific mailboxes only?
by Alex 27 Aug '12

27 Aug '12

Hi, is it possible to configure dovecot so that it only serves mailboxes of specified users? All other users should be completely ignored so that no indexing of messages or other resource consuming actions take place. Thanks in advance, Alex
