OpenFTS
by Cerebus 05 Apr '19

05 Apr '19

All the discussion on FTS reminds me, is there any plan to support OpenFTS in dovecot or is there a reason preventing that? -- This is my signature. There are many like it, but this one is mine.

SMTPUTF8 support
by sylvhem＠lepubdelobservateur.fr 05 Apr '19

05 Apr '19

Hi, I'm currently trying to set up SMTPUTF8 on my mail stack, but I can't find any information on Dovecot's RFC 6531 support. Has it been implemented yet? If so, does anyone know how to activate it? Regards. -- Sylvhem

Hi, What's the recommended way to handling timeouts on large mailboxes given the hardwired request timeout of 60s in solr-connection.c: http_set.request_timeout_msecs = 60*1000; /Peter

doveadm backup + ISO 8859-1 mailbox name
by Michael Goth 04 Apr '19

04 Apr '19

Hi! I'm trying to migrate a mailbox from an old IMAP server (not Dovecot) to a new Dovecot server with 'doveadm backup'. The command fails because of an unexpected character in a mailbox name: doveadm -o imapc_user=ag(a)example.org \ -o imapc_password=XXX \ -o imapc_host=old-mailserver.webflow.de \ -o imapc_port=993 \ -o imapc_ssl=imaps \ -o imapc_ssl_verify=no \ -o imapc_features=rfc822.size,fetch-headers \ -o ssl_client_ca_dir=/etc/ssl \ backup -R -f -x ~* -u migration-ag(a)example.org imapc: dsync(migration-ag(a)example.org): Info: imapc(old-mailserver.webflow.de:993): Connected to 1.1.1.1:993 (local 2.2.2.2:46154) dsync(migration-ag(a)example.org): Error: Failed to access mailbox Entw?rfe: mailbox does not exist The problem is with "Entw?rfe" here. It's actually Entw<0xfc>rfe, which translates to "Entwürfe" in ISO-8859-1. Why can't doveadm find that mailbox? Is the old mailserver misbehaving (I hope not because I have no idea how to change that...), or does this happen on the new server? Can I tell doveadm something that makes this work?

Autosubscribe to public folder
by Рустам 04 Apr '19

04 Apr '19

Hello everyone! I am trying to migrate from Dovecot 1.2 to Dovecot 2.2 and I can`t find information how to subscribe all users to public folder. In Dovecot 1.2 I have a few strings kind of "autosubscribeX = Public.Documents" and every users get subscribed to this Public folders and can`t unsubscribe. This is a goal. Is any posibility to make the same in Dovecot 2.2 or each user have to susbscribe to public folders themselves and this is kind of policy of Dovecot 2.2? -- С уважением, Рустам Багов.

TFA authentication in dovecot, using XMPP and RFC 4226
by André Rodier 03 Apr '19

03 Apr '19

Hello, I would like to implement some kind of two factors authentication, in Dovecot. I am thinking about using the post login script, to check for unusual behaviour, like say, a different country / IP address or an unusual hour. I already wrote a simple shell script that check these factors, but now, I have some options for the following, and I need to know your opinion if this is feasible or not. I want to use google authenticator Debian package (support the HMAC- Based One-time Password (HOTP) algorithm specified in RFC 4226 and the Time-based One-time Password (TOTP)) The challenge would be send via XMPP. This second part is fairly easy to do, I have all the packages on Debian, for instance sendxmpp. The first tests are promising. In case of success, the IP address is added to the list, let's say for one month... My back-end for authentication is OpenLDAP. My questions are: - Do you see any performance issues for other users or login processes, if I implement this? - I am planning to use a timeout, for instance one minute to confirm the connection. Does Dovecot have a timeout on its side, that would abort the connection before? Otherwise: - Is it possible to have multiple authentication back-ends in Dovecot? For instance LDAP and/or OTP? - I think to have seen some TFA options in Dovecot, but AFAICS, they are mandatory. Thanks for your insights, and this fabulous software. -- André Rodier HomeBox: https://github.com/progmaticltd/homebox

where shall I enforce sieve and quota plugins
by luckydog xf 03 Apr '19

03 Apr '19

Hello, guys, I'm going to using sieve and quota plugins, but I'm not sure where shall I enforce against properly? I see somebody uses them against 20-imap.conf, 15-lda.conf, or 20-lmtp.conf I use LMTP as MDA, so where is the correct location to call these plugins and why? Thanks,

Trying to track down source of duplicate messages
by Alex 02 Apr '19

02 Apr '19

Hi, I have a fedora28 system with dovecot-2.3.5 and I'm trying to figure out why I'm increasingly receiving duplicate emails. The message IDs are exactly the same. It's always two of the same messages. I don't think it's ever occurred in the inbox. It doesn't happen with every message or seemingly in every folder. I've read about dovecot deduplicate, but of course I want to prevent them from being duplicated in the first place. It's also happening much more frequently now. Could something in my configuration cause this problem? Below is the contents of my doveconf # 2.3.5 (513208660): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.5 (2483b085) # OS: Linux 4.20.11-100.fc28.x86_64 x86_64 Fedora release 28 (Twenty Eight) #

ssl_min_protocol

What are the possible settings for ssl_min_protocol? I only see it on the upgrade page where it mentions the default is TLSv1. Searching on the dovecot page gives me "Your search query "ssl_min_protocol" didn't return any results." -- Up the airy mountains, down the rushy glen... From ghosties and bogles and long-leggity beasties... My mother said I never should... We dare not go a-hunting for fear... And things that go bump...

sql table definitions

Hi all, Trivial question ... I'm using PostgreSQL for my auth db. I used the example CREATE TABLE statement in the config file, but now I find the fields are too short. I assume dovecot will be fine with 'text' type columns replacing the varchars? Or failing that, I can change the length of the varchar fields? Cheers, Richard
