Re: [Dovecot] zlib config questions

You only need to add the zlib plugin to mail_plugins once. As far as I know, there's no indication in the logs that mail is being compressed, and the filename isn't modified to indicate that it's compressed, but, of course, the files are zlib data on disk. One gotcha if you're using maildir is, if you're planning to compress old mail, make sure that the S= and W= sizes in the filenames are correct, otherwise dovecot errors and closes the client session, and it can't repair the filename on it's own.

[Dovecot] delete message with specified id
by Костырев Александр Алексеевич 08 Dec '13

08 Dec '13

Good day, everyone! Could someone help me to find a way to delete message with certain id from all users's mailboxes? What seems to be a problem: I have configured exim + dovecot lmtp I got a long list of aliases in BD in form of: +----------+-------------------------------------+ |alias_name recipients | (for example) -----------|-------------------------------------+ | list_a | user1@example.org,user2@example.org | +----------|-------------------------------------+ When I send a message to that list_a, user1 and user2 get the mail and I see this in log: Dec 6 12:12:27 beta-mail dovecot: lmtp(16419, user1(a)example.org) copy from INBOX: box=INBOX, uid=1, msgid=<E1VojxY-0004Gl-Gu@beta-mail>, size=570 Dec 6 12:12:27 beta-mail dovecot: lmtp(16419, user1(a)example.org) oCOXKmAkoVIjQAAA635u4w: msgid=<E1VojxY-0004Gl-Gu@beta-mail>: from=root@beta-mail: subj=: saved mail to INBOX Dec 6 12:12:27 beta-mail dovecot: lmtp(16419, user2(a)example.org) copy from INBOX: box=INBOX, uid=1, msgid=<E1VojxY-0004Gl-Gu@beta-mail>, size=570 Dec 6 12:12:27 beta-mail dovecot: lmtp(16419, user2(a)example.org) oCOXKmAkoVIjQAAA635u4w: msgid=<E1VojxY-0004Gl-Gu@beta-mail>: from=root@beta-mail: subj=: saved mail to INBOX Is it possible to delete these letters with known msgid=<E1VojxY-0004Gl-Gu@beta-mail> from all users mailboxes with couple of simple commands ? How do I do it currently: in exim's log I get mailaddress of a user, get into his mailbox (wich cd), find the letter I need, with ls -i I get inode, search (with find) through all users mails and delete all files with that inode, then I have to rebuild dovecot indexes with doveadm mailbox status -A -t all INBOX -- С уважением, Костырев Александр администратор Linux-систем

[Dovecot] pigeonhole openssl s_client
by LEVAI Daniel 08 Dec '13

08 Dec '13

Hi! I'm trying to get information about a server certificate from a pigeonhole sieve server. Various connection attempts show only "wrong version number" or "unknown protocol" errors from openssl: $ openssl s_client -connect example.com:4190 { -tls1, -tls1_1, -tls1_2 } [ -starttls { imap, pop3 } ] None of these work. I'm trying to see who signed the server cert. How could I do this? Thanks, Daniel -- LÉVAI Dániel PGP key ID = 0x83B63A8F Key fingerprint = DBEC C66B A47A DFA2 792D 650C C69B BE4C 83B6 3A8F

[Dovecot] Replication via sneakernet
by David Bishop 07 Dec '13

07 Dec '13

Is there a way to get a running transaction log from a Dovecot instance to synchronize (and I use that word very, very loosely) multiple instances that don't share a network? Why I would want to do such a thing: I have a couple way stations along a long, winding road through very hilly country, and at each of these stations, I have a few people (and many, many more at one end of the road). Which people are where varies from hour to hour (but they're all members of a known, larger, group of people with accounts). It would be helpful to get communication (however limited) along this road (and establishing direct communication, either through radio or landline, is not feasible within the budget constraints I have), and it is possible to store a complete copy of the mail spool to a small box at each station (the total mail spool over the period I care about is in the tens of megs). There are trams shuttling back and forth along this road (stopping at each station), and adding a small box (such as a weatherproofed Raspberry Pi with a wifi dongle) to transport files up and down the road is pretty simple. Doing incremental copies of the mail spool is also simple, keeping track of files that get moved or deleted is a bit harder (but still not that bad), but I have no idea how hard it is to track what messages have been seen, especially for the shared folders (which we use instead of mailing lists). I realize this is not a "normal" use of Dovecot, but given this, does anyone who knows the software (and how it keeps track of messages) better have suggestions on how to approach the problem?

[Dovecot] Easy migration from Dovecot 1.2.16 ppc maildir to 2.1.17 amd64 mdbox
by Philippe Lelédy 07 Dec '13

07 Dec '13

Hi After http://retrospekt.dk/2011/08/migrating-maildir-to-dovecot-2-0-dbox/ I used a two phases process. The first, transfering over the network, is done by this shell function, on the *new* server. The argument is the <user> fetchOldServer () { rsync -poazuHK --exclude="**/dovecot.index*" \ -e ssh root@oldServer:/var/mail/Maildirs/$1 /var/mail/oldServer/ } I had to add --exclude="**/dovecot.index*" because of a change of endianness (ppc -> amd64). the second, having dovecot import the folder, is done by this second fonction dsync () { doveadm backup -R -u $1(a)mondomaine.fr maildir:/var/mail/oldServer/$1 } this one is really fast. Both in one function doveImport() { fetchOldServer $1 && dsync $1 } I tried for initial load to empty mailbox. I am not sure it will works on a non empty mailbox. But would be nice, as it would allow a fast last minute sync before switch, minimizing downtime. Ph. Le

Re: [Dovecot] Dovecot readable compressed mail archive
by Dave Hall 06 Dec '13

Alan, My goal is to reduce the file count in my backups. Based on the information at the link you sent it looks like for a Maildir setup the file count remains the same. Do you know if it's possible to have a mixed config with Dovecot where for a given user the Inbox is a maildir, but the archives are compressed mbox files? Thanks. -Dave On 12/04/2013 02:06 PM, Alan McGinlay wrote: > http://wiki2.dovecot.org/Plugins/Zlib try this.. Excuse the lack of quoted text, im on my phone

[Dovecot] Authentification Dovecot + Samba4

Hello list, I am struggling with setting up dovecot 2.1.7 with samba 4.1.2 on debian wheezy. Dovecot should authenticate via LDAP, but I cannot get it to work reliably.

[Dovecot] SQL as a storage backend
by Zachary Sturgeon 06 Dec '13

06 Dec '13

Hello, I am researching using dovecot with an SQL database as the storage backend. From what I've read, dovecot only supports mbox style file storage, but I'd like to investigate the possibility of using a database instead. According to http://dovecot.org/pipermail/dovecot/2006-June/013818.html, this possibility has been explored before and has generally been accepted that Dovecot is not optimized to handle this. Any suggestions? - Zachary Sturgeon
