rescann / reindex / rebuild a subfolder structure
by Götz Reinicke - IT Koordinator 13 Jun '17

Hi, an user is missing all mail from a folder and all subfolders which are still saved in the users maildir directory on the dovecot server. From an imap client she sees the main folder but empty. No subfolders. She told me with an other imap client and a new created account she has the same problem. Question: Can I resync / regenerate some folder... index.... something....-files from the dovecot side? Thanks for hints and regards . Götz

This is a consequence of writing secure software: it employs least privilege so that a fault will not result in someone being able to mess around with someone else's mail (or indices). GID can also govern access to shared mailboxes. Joseph Tam <jtam.home(a)gmail.com>

Pardon my naievty, but couldn't you just remove this namespace altogether and get rid of at least one set of duplicates (although it probably keep the non-preferred one).

service(auth): command startup failed?
by HL1234 12 Jun '17

12 Jun '17

Hello, I need help because since some days I can not figure out what error this is and where it come from. I have used dovecot since years. Know after an update it is broken. First I like to give you some data: It's a FreeBSD 11.0 Server with sendmail (SMTP) and dovecot for IMAP with SSL. #dovecot --build-options Build options: ioloop=kqueue notify=kqueue ipv6 openssl io_block_size=8192 Mail storages: shared mdbox sdbox maildir mbox cydir imapc pop3c raw fail SQL drivers: mysql Passdb: checkpassword ldap pam passwd passwd-file sql Userdb: checkpassword ldap nss passwd prefetch passwd-file sql #dovecot --version 2.2.30.2 (c0c463e) I install the update with the FreeBSD ports. Before the update all was running fine. The state know is: form my client Outlook I can send eMail above SMTP. When I try to get my eMails by the IMAP-Server it is blocked. I have look around in the config files but I see nothing what has could be changed. I have tried to make new *.pem files with using the script in /usr/local/share/examples/dovecot/ but this havn't bring a solution. I need help for this error i see in the logs: dovecot.log master: Error: service(auth): command startup failed, throttling for 2 secs auth: Error: auth: environment corrupt; missing value for DOVECOT_ auth: Fatal: unsetenv(RESTRICT_SETUID) failed: Bad address auth: Error: auth: environment corrupt; missing value for DOVECOT_ auth: Fatal: unsetenv(RESTRICT_SETUID) failed: Bad address ..... dovecot-info.log imap-login: Info: Disconnected: Auth process broken (disconnected before auth was ready, waited 1 secs): user=<>, rip=77.178.105.78, lip=88.74.25.120, TLS Jun 12 23:01:15 imap-login: Info: Disconnected: Auth process broken (disconnected before auth was ready, waited 8 secs): user=<>, rip=58.218.194.81, lip=88.74.25.120, TLS handshaking .... dovecot-debug.log imap-login: Debug: SSL: where=0x10, ret=1: before/accept initialization [77.178.105.78] imap-login: Debug: SSL: where=0x2001, ret=1: before/accept initialization [77.178.105.78] imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 read client hello A [77.178.105.78] imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write server hello A [77.178.105.78] imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write certificate A [77.178.105.78] imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write key exchange A [77.178.105.78] imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 write server done A [77.178.105.78] imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 flush data [77.178.105.78] imap-login: Debug: SSL: where=0x2001, ret=1: SSLv3 read client certificate A [77.178.105.78] imap-login: Debug: SSL: where=0x2002, ret=-1: SSLv3 read client key exchange A [77.178.105.78] imap-login: Debug: SSL: where=0x2002, ret=-1: SSLv3 read client key exchange A [77.178.105.78] auth: Debug: Loading modules from directory: /usr/local/lib/dovecot/auth auth: Debug: Module loaded: /usr/local/lib/dovecot/auth/lib20_auth_var_expand_crypt.so auth: Debug: Read auth token secret from /var/run/dovecot//auth-token-secret.dat Have anyone an idea what is going wrong and how to fix it?

Re: Log authentication attempts
by j.emerlik 12 Jun '17

We alse have same problem, now we are running Dovecot 2.2.30.2 and also use Dovecot SASL for SMTP authentication (postfix 2.11). We need to save all failed login attempts to database as source IP address, username and date and time but post-login script can do this but only after successful login. Failed login attempts information may be useful in the fight with bruteforce attacks. It's possible to execude some script after failed login ("Password mismatch") ? Regards, Jacek

namespace and folders
by Gregory Sloop 12 Jun '17

12 Jun '17

Using mbox format and this namespace namespace { inbox = yes hidden = yes prefix = INBOX/ } [Though I've also tried, seemingly, a million different namespace options to "fix" my problem.] It's a migrated setup from a 1.x dovecot install from Ubuntu 12.04, now on 16.04 The problem is in TBird [I haven't tested with any other mail clients] and IMAP; with that name-space I get all the folders both at the root level [same as inbox], as well as below inbox. [The same folders, pointing at the same underlying messages.] For example, if there's a folder "blah" and I subscribe to it, "blah" shows both at the same level as inbox, as well as a sub-item of inbox. If I unsubscribe from folder "blah" it also unsubscribes from the subfolder "blah" under inbox, and at the root level. [I hope that's clear enough...] This is not a terrible problem, but it's cosmetically ugly and confusing for users. I'd prefer to only see these folders as subscribed as sub-folders [or sub-items] under inbox. I'd guess I'm making some stupid beginner error, but I've not been able to figure it out, as of yet. Any help would be greatly appreciated. -Greg

Michael p.s. Once this is resolved I hope to be able to use "make check". I had to massage the Makefiles to get gnulib/getopt to link into dovecot. Once I can run "make check" I'll request help on how to get a new directory included in the Makefile list, and also assistance with making sure it can also work with out-of-tree builds.

doveadm ssl error when upgrading from 2.2.27 to 2.2.29
by Pallissard, Matthew 12 Jun '17

12 Jun '17

I'm starting to see the following error when upgrading from 2.2.27 to 2.2.29. doveadm(ip.add.re.ss): Error: doveadm client disconnected before handshake: SSL_accept() failed: error:1417A0C1:SSL routines:tls_post_process_client_hello:no shared cipher Downgrading from 2.2.27 resolves, error still persists in 2.2.28. I'm using openssl 1.1.0.f and an ec cert/key with the following curve. ASN1 OID: prime256v1 NIST CURVE: P-256 Does anyone know anything about this off the top of their head? If not I'll try to git-bisect 2.2.27 -> 2.2.28 and see if I can find any offending commits later on this week. -- Matt Pallissard
