Dovecot 2.3.0 TLS
by Hauke Fath 07 Jul '19

07 Jul '19

All, our dovecot installation provides a bundle of intermedia CA certificates using the ssl_ca option. 2.3.0 does not supply the bundle, resulting in various clients either complaining about an unverifiable server cert, or quietly not connecting. The log has Jan 5 17:01:46 Bounce dovecot: imap-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=XXX, lip=YYY, TLS handshaking: SSL_accept() failed: error:14094416:SSL routines:SSL3_READ_BYTES:sslv3 alert certificate unknown: SSL alert number 46, session=<uKK/kAlia+GCUyU5> We fixed the issue by downgrading to 2.2.33.2.

Automatically subscribe to the INBOX folder
by glts 26 May '19

26 May '19

Hello, I am using the ‘auto = subscribe’ feature in the mailbox configuration section in the usual fashion (as shown in conf.d/15-mailboxes.conf): namespace inbox { inbox = yes mailbox Drafts { special_use = \Drafts auto = subscribe } ... } When I connect to an account with the Thunderbird mail client, those mailboxes/folders get autocreated and autosubscribed. Good! INBOX, however, does not get subscribed to automatically. When I look at the account’s subscriptions in Thunderbird, all folders are subscribed, except INBOX. How can I enable autosubscribe for the INBOX folder (like the other folders)? Is there an option for this? This is in Dovecot 2.2.22. Cheers, David

[Dovecot] Dovecot LDA/LMTP vs postfix virtual delivery agent and the x-original-to header
by Charles Marcus 19 Apr '19

Does anyone know if the use of LMTP (or even the dovecot LDA) still loses the x-original-to header that the postfix vda adds and that I rely heavily on (since I use a lot of aliases), and if it does, is there any solution to get the original recipient added back in before final delivery? Everything I'm reading says that LMTP is better, but I really do need this header (or one like it) to be there so I know who the original recipient was (for filtering and other purposes). Thanks, -- Best regards, Charles

SELinux policy to allow Dovecot to connect to Mysql
by Robert Moskowitz 05 Feb '19

05 Feb '19

As I have noted in previous messages, I been getting the following on my new mailserver: Apr 7 10:17:27 z9m9z dovecot: dict: Error: mysql(localhost): Connect failed to database (postfix): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (13) - waiting for 25 seconds before retry They go away when I setenforce 0. It is not a timing issue as I earlier thought. So I googled dovecot mysql selinux and the only worthwhile hit was: http://zszsit.blogspot.com/2012/12/dovecot-mysql-selinux-issue-on-centos6.h… that provides a /etc/selinux/dovecot2mysql.te and other selinux stuff. Is there a simpler way like a setsbool option? With all the howtos on dovecot with mysql, it is interesting that none of them seem to have this problem. Maybe because they connect to mysql through TCP port 3306 which has ITS set of problems (like MariaDB defaults to not listening on TCP). thanks!

Hello! dsync SSL still doesn't work for replication, so I've disabled it and tried to sync without. But I have a problem with temp directory. Is it possible to change path to temp folder?

auth_policy in a non-authenticating proxy chain
by Peter Mogensen 15 Sep '18

15 Sep '18

Hi, I was looking into the new Authentication Policy feature: https://wiki2.dovecot.org/Authentication/Policy I had kinda hoped that I would be able to enfore this in a proxy running in front of several backends. This proxy does not authenticate. It use "nopassword". But I realize that the "succes" reported in the final authpolicy req. (command=report) is not what is actaully happening on the IMAP protocol level, but rather the result of the passdb chain in the proxy. (I should probably have predicted this, it's kinda reasonable). However... since the proxy use "nopassword", ALL passdb lookups result in "success", so the proxy will never report an authentication failure to the authpolicy server. This, of course, forces me to do the authpolicy check on the backend with a shared state, but It would still have been nice to have the proxy being able to do the first "command=allow" req. and reject attemps already there even though the backend does "command=report". /Peter
