charset-specific searches, and continuation lines
by Eric Abrahamsen 12 Sep '14

12 Sep '14

Hi there, I'm looking into improving IMAP search support for the Gnus Emacs mail client, and trying to add the ability to search non-ascii characters. So far as I know, I start this invocation with something like: . UID SEARCH CHARSET UTF-8 TEXT {NNN} Where NNN is the number of bytes in my search string. Dovecot then responds with: + OK So... what do I do then? I don't actually know what the next statement is, to provide the actual search string itself. Googling has proved unhelpful, as most of the examples online don't actually show this "+ OK" response. Can someone just briefly outline what's meant to happen next? I've tried including the search string immediately after the byte-size, separated by various combinations of \n\r, but that always gives me a "Missing LF after literal size" error. I'm using the Archlinux dovecot package, which reports version 2.2.13-1. Thanks! Eric

Problem with virtual folders
by Urban Loesch 11 Sep '14

11 Sep '14

Hi, I'm trying to activate some virtual folders on a new installed dovecot server. My plan is to have two virtual folders like "All" and perhaps "Unseen", like Gmail style for the first step. - All: lists me all messages in the users mailbox - Unseen: all unseen messages in the users mailbox I'm using dovecot EE Release: ii dovecot-ee-core 1:2.2.13.8-1 amd64 secure mail server that supports mbox, maildir, dbox and mdbox mailboxes ii dovecot-ee-imapd 1:2.2.13.8-1 amd64 secure IMAP server that supports mbox, maildir, dbox and mdbox mailboxes ii dovecot-ee-lmtpd 1:2.2.13.8-1 amd64 secure LMTP server for Dovecot ii dovecot-ee-managesieved 0.4.3-1 amd64 secure ManageSieve server for Dovecot ii dovecot-ee-mysql 1:2.2.13.8-1 amd64 MySQL support for Dovecot ii dovecot-ee-sieve 0.4.3-1 amd64 sieve filters support for Dovecot But I can't get it to work. I can see the virtual folders in my Thunderbird, but the folders are empty and can't find any errors in mail log. I also tried it with "mail_debug = yes".

The virtual folders are stored in "/home/virtual/XXX" and are containg only the file "dovecot-virtual". Like: "/home/virtual/All/dovecot-virtual": <--------------------- * all ---------------------> Note: I just have active virtual folders on a different dovecot server version "2:2.2.13-1~auto+74". I copied the configuration from this server. The only three differences between the two servers are: - Server version is different. - The prefix of the default namespace on the new server is "prefix = INBOX/" and not "prefix =" - Mail storage and index files are seperated in different folders on the new server. Here are the relveant namespace configuraiton from the server where it ist working fine: ... namespace { list = children location = mdbox:/home/vmail/%%d/%%n prefix = shared/%%u/ separator = / subscriptions = no type = shared } namespace { hidden = no inbox = no list = children location = virtual:/home/virtual:INDEX=~/virtual prefix = [rolmail]/ separator = / subscriptions = yes type = private } namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Items" { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = separator = / type = private } ... Have you any hint for me how I can fix my problem. Thanks and regards Urban Loesch

minimal configuration for lucene fts
by Eric Abrahamsen 11 Sep '14

11 Sep '14

Hi, I'm using dovecot (version 2.2.13 on archlinux) in the simplest, no-brainer way possible. It sits between mbsync, which I use to fetch mail from servers, and Gnus, my MUA. Both mbsync and Gnus connect to dovecot with an invocation like this: /usr/lib/dovecot/imap -o mail_location=maildir:$HOME/.mail/ea/ I have three different mail accounts, all that changes is the final directory on the mail_location path above. I haven't touched anything else: there's no running daemon, no configuration, no user database, no PAM, no nothing. Now I'm trying to set up text searching via lucene, but all the examples I've seen online assume a full running daemon and user accounts. I tried to fake it by running: doveadm index -u eric@localhost -q INBOX -o mail_location-maildir:/home/eric/.mail/ea but it was clearly expecting a user database. Is there any way to create text indexes for my three different accounts, in their respective directories, without fully setting up a running dovecot? I'll do that if I have to, but my current setup works great, and is very simple, and I'd like to keep it simple if I can. Thanks! Eric

Dovecot can't read mail, creates duplicate directories

CentOS 6.5, dovecot 2.0.9-7 I used http://www.linuxmail.info/postfix-dovecot-ldap-centos-5/ to configure LDAP authentication for postfix and dovecot.

Re: Configure Dovecot Master User

Just a wild-ass guess, but shouldn't "master_user=%u" be something like "master_user=muser" where "muser" is the master user as defined in your master password file?

outlook 2013
by Bob Miller 10 Sep '14

10 Sep '14

I am trying really hard to wrap my head around why people insist on using this program... Where I have outlook 2013 users, I have had nothing but problems getting their mail to work with imap. my solution has been to set them up with pop, which works just like it always has. Or move them to a different program. recently, I have a customer who requires multiple machines, all using outlook 2013, to access the same email address, so pretty much have to use imap. if I set up just one of the machines with imap, it works more less as expected, with hiccups such as mail taking an hour or two or more to show up. But shortly after I connect a 2nd machine to the same account, one or both machines start to go wonky. Symptoms include deleted items returning, read messages becoming unread again, and duplicates being constantly created and deleted. The last I can confirm by watching in webmail and refreshing the inbox every few seconds; as mail shows up and deletes in outlook, so it does in webmail too. On my test machine connected to the same server, I have evolution, outlook and thunderbird all connecting to one account with no problems. Well, outlook hiccups, but it's not unusable. And I have other users on the system that share email accounts across a variety of other clients and platforms, including older versions of outlook. I have tried checking message rules, there are none; removing all folder subscriptions; running scanpst, which finds errors even before the account finishes syncing and ever time I run it after that; I have looked for viruses/malware; I have confirmed there is no forwarding or some trickery happening on the server; chkdsk and similar hardware checks all come up clean, the computers are only a couple of months old; I have got certs set up with SANs and the CA installed such that outlook does not error on the certificate; and I have tried just about every combination of settings that seem relevant. The one thing that does seem to work, at least for a few minutes or an hour or two, is deleting and recreating the accounts on one of the computers. But the problem inevitably returns in short order. Surely people have outlook 2013 connecting via imap to dovecot without problems; is there some special trick that google is hiding from me? -- Computerisms Bob Miller 867-334-7117 / 867-633-3760 http://computerisms.ca

Dovecot replication
by Hoggins! 10 Sep '14

10 Sep '14

Hello list, I'm trying to achieve very simple replication, but I'm not sure if I'm starting the good way. I have two Dovecot servers that use the same GlusterFS storage. Of course, the indexes get corrupted eventually, even if I apply an "NFS-like" configuration. So I'd like to synchronize my two servers with each other. I'm trying to follow this page : http://wiki2.dovecot.org/Replication, but I have to admit that it's not really self-explanatory. I got several errors, so I decided to start fresh, and that is why I'm not giving you any configuration, but I prefer asking if I have the prerequisites. The page states that my userdb should have "user listing", and that you can check it by issuing `doveadm user '*'`. But I don't know what it's supposed to produce, apart from my userlist (my userdb is the system passwd file). As my servers are located on the same private LAN, I decided I would not go with the SSH replication solution, but with the simple mutual TCP connection... Maybe this is a wrong start. Any help will be appreciated. Thanks in advance !
