Multiple IMAP Mailboxes and one collection folder
by Dieter Knopf 31 Mar '16

31 Mar '16

Hello, we use many IMAP folders and now we are searching for a way to display all mails inside this folders in one collecting folder. The advantage for us would be the possibility to view all new incoming mails in one folder. It would be possible to use the standard MAIL App on the iOS without problems. I could simply make a copy of all mails in one folder with Sieve, but then the Per-user Seen Flag would be useless, because the mail inside the folder is still unread. Is there a way to show some way of collecting folder for every user? Thanks Dieter

Dovecot plugin pthread issue
by qmail＠top-consulting.net 31 Mar '16

31 Mar '16

I am using FreeBSD 10.1 and Dovecot 2.2.22 with the Openchange plugin - https://github.com/openchange/openchange/tree/master/mapiproxy/services/plu… (https://github.com/openchange/openchange/tree/master/mapiproxy/services/plu…) The plugin compiles just fine and works up until when it tries to create a socket using nanomsg, which uses a pthread_create() call. At that point dovecot-lda just hangs indefinitely. I've read that -pthread must be included in all the components that might end up using it. So checking with ldd: nanomsg does include libthr ( pthread equivalent in FreeBSD ) openchange plugin also includes libthr dovecot-lda doesn't include libthr Would dovecot-lda also need to be compiled with -pthread ? Is it safe ? How can it be done ? Thank you!

Dovecot-LMTP and LDAP: passdb doesn't support credential lookups
by Niols 30 Mar '16

30 Mar '16

Hello, Sorry, this might be a newbish question, but I really can't get the answer by myself. I'm trying to setup a mail server using LDAP to authenticate users, and I keep receiving the errors: passdb doesn't support credential lookups passdb doesn't support lookups, can't verify user's existence when I send test mails to (existing) users. I'm already using the LDAP server for other purposes, and it's working fine. I can't (or I don't want to) give read access to the userPassword attribute, so I want to use a authentication bind: http://wiki.dovecot.org/AuthDatabase/LDAP/AuthBinds I've already managed to have postfix working with this LDAP server, the users (and their aliases) are correctly recognized. Postfix then sends the mails to Dovecot (2.2.13, Debian Jessie's version) with dovecot-lmtp. Here is my /etc/dovecot/conf.d/auth-ldap.conf.ext. I use the static driver for userdb, and the LDAP driver for passdb. passdb { driver = ldap args = /etc/dovecot/dovecot-ldap.conf.ext } userdb { driver = static args = uid=mail gid=mail home=/var/mail/%u } Here is my /etc/dovecot/dovecot-ldap.conf.ext file. hosts = localhost ldap_version = 3 dn = cn=dovecot,ou=services,dc=niols,dc=fr dnpass = a-random-password auth_bind = yes base = ou=people,dc=niols,dc=fr pass_filter = (&(objectClass=inetOrgPerson)(mail=%u)) I haven't set the user_filter and user_attrs values, since I thought these would only be usefull for userdb. I haven't set the pass_attrs value, since I don't see why it would be needed (I just need to be able to bind my user, right?). I can't auth_bind_userdn since the e-mail address aren't necessarily related in any way to the user dn. I assumed %u was going to be replaced by the user's full e-mail address. I tried to play a bit with these values to find a working configuration, without success. I tried to search myself on the LDAP server, using the provided dn and dnpass, and I succeeded. I tried to activate debug logs, but that didn't give me much more information (full debug log at the end of this e-mail). I think the problem is that passdb cannot find the user on the LDAP server, but I don't know why. I believe the problem is lying in my non-comprehension of what userdb and passdb actually do. I tried to find out by myself, and I'm here because I didn't manage to do so. I'm sorry if this post looks stupid. Any help and any comments of any kind would be greatly appreciated. Regards, Niols PS: Here is the full debug log that I get after sending a test message to test(a)niols.net (.net vs. .fr: this is not a mistake, I use my .net domain for testing purposes while I use my .fr domain for eveyday life) with swaks: lmtp(3208): Connect from local auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libauthdb_ldap.so auth: Debug: Read auth token secret from /var/run/dovecot/auth-token-secret.dat auth: Debug: LDAP initialization took 0 msecs auth: Debug: master in: USER 1 test(a)niols.net service=lmtp auth: Debug: ldap(test(a)niols.net): passdb doesn't support credential lookups auth: Error: static(test(a)niols.net): passdb doesn't support lookups, can't verify user's existence auth: Debug: userdb out: FAIL 1 lmtp(3208): Error: user test(a)niols.net: Auth USER lookup failed lmtp(3208): Disconnect from local: Successful quit

CentOS RPM updates?
by J Landwehr 30 Mar '16

30 Mar '16

Has CentOS stopped distributing dovecot updates via yum? The current version there is 2.2.10 - which is now over two years old. The link on: http://dovecot.org/download.html <http://dovecot.org/download.html> to “RPMs for Fedora and RHEL/CentOS” http://packages.atrpms.net/dist/el6/dovecot/ <http://packages.atrpms.net/dist/el6/dovecot/> is also broken. Would be great if someone could please point me to alternative locations for authentic RPMs

talloc access after free error ntlmssp_server.c:457
by J Landwehr 30 Mar '16

30 Mar '16

Our new/fresh dovecot imap installation on CentOS (latest from yum repository, which is 2.2.10) is locking up with a panic on a consistent basis and denying service to subsequent clients. The behavior is repeatable. Have spent weeks debugging and trying different configurations with no success. Specific /var/log/maillog error messages are: 12:06:54 dovecot: auth: Error: talloc: access after free error - first free may be at ../auth/ntlmssp/ntlmssp_server.c:457 12:06:54 dovecot: auth: Error: Bad talloc magic value - access after free 12:06:54 dovecot: auth: Error: PANIC (pid 2570): Bad talloc magic value - access after free Our configuration is based on the instructions for NTLM authentication with our Windows 2012R2 AD/Domain server: http://wiki2.dovecot.org/HowTo/ActiveDirectoryNtlm <http://wiki2.dovecot.org/HowTo/ActiveDirectoryNtlm> Here are the steps to reproduce: 1. Fresh boot of CentOS server, only configured for postfix/dovecot 2. Connect with Outlook 2016 12.0.4312.1000 32bit on Win7 via IMAP to this dovecot server 3. Any existing and new mail loads in OK to inbox - so authentication is working OK to AD domain server 4. Send an email to someone from Outlook 5. SMTP process completes, message is delivered - 6. dovecot immediately panics on servers, Authentication to dovecot no longer works 7. <systemctl restart dovecot> will hang until a <kill -9> on the “dovecot/auth” PID is performed The issue is with steps 6/7 immediately after 4/5- and is intermittent. Steps 1-3 always work OK, as do 4-5. Further, inbound emails received on this server when no IMAP client is running are always received just fine and dovecot doesn’t hang. Sometimes I have to send a few email messages with steps 4/5 before the issue with 6/7 happens. If I tail -f /var/log/maillog on the server, I can usually determine when 6/7 will fail because there is a line or two with: "dovecot: map: Disconnected: logged out message” being shown, even though the Outlook client is still open. After I see that Outlook closed an IMAP session, even though outlook is still running, I can send a message from Outlook and after it appears in my inbox, dovecot panics/hangs immediately Authentication is otherwise working, e.g. test with: /usr/bin/ntlm_auth —username=alice occasionally takes several seconds to respond, but is usually immediate response is always NT_STATUS_OK: Success (0x0) (I welcome tips to make ntlm_auth always respond more quickly!) I have tried adding lines to smb.conf like: win bind cache time = 300 win bind offline login = true No success I have also looked further into the detailed debugging logs and there is: dovecot: auth: Error: Go user=[alice] domain=[OFFICE] workstation=[pc1] len1=24 len2=290 dovecot: auth: error: login for user [OFFICE]\[alice]@[pc1] failed due to [Wrong Password] dovecot: auth: Error: GENSEC login failed: NT_STATUS_LOGON_FAILURE dovecot: auth: winbind(?,x.x.x.x,<XXX>): user not authetnicated: NT_STATUS_LOGON_FAILURE But I am not sure why there would be that error, since earlier IMAP sessions are working just fine with the same exact domain/username and password. It seems to be something about Outlook quickly opening up new simultaneous IMAP sessions with a CONT command, and NTLM authentication somehow fails with one of them, and panics. It always seems to be when sending an email. Like the process of either receiving a new msg in the inbox and/or also posting the just sent message into the Sent Items folder via IMAP (perhaps when it happens simultaneously, as in a message you cc yourself on) is somehow triggering this. Here is more detailed information that can hopefully help track this down.
