v2.2.21 released
by Timo Sirainen 13 Dec '15

13 Dec '15

http://dovecot.org/releases/2.2/dovecot-2.2.21.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.21.tar.gz.sig Due to a bit bad doveadm bugs in v2.2.20 here's a fixed v2.2.21. Also from this release forward we're finally using git with branches to make new releases. So new releases will have a bit more time to stabilize in the branch before they're being released (while still allowing new features to be developed in the master development branch). We already did something like this for the enterprise releases, but now it's done for community releases as well. - doveadm mailbox list (and some others) were broken in v2.2.20 - director: Fixed making backend changes when running with only a single director server. - virtual plugin: Fixed crash when trying to open nonexistent autocreated backend mailbox.

System-user-controllable custom passwords and mail locations
by Michal Petrucha 12 Dec '15

12 Dec '15

Hello everyone, I'd like to set up dovecot so that it uses the standard system accounts, but with different passwords specific to email. Seems like a fairly common setup, but the catch is, I want the users to be able to set their passwords themselves, without needing any assistance from a server administrator. I'm wondering what's the easiest way of implementing this. From what I've understood, this requirement would probably rule out a separate passwd-file (since the standard Linux passwd doesn't seem to support using a custom passwd file), SQL, flat-file dict, and Redis (since you can't give users access only to their row, or dict key; it's either the entire database (or flat file), or nothing). (Of course, I could work around that limitation by writing a C program that I would install as SUID root, which would only change the invoking user's password, but I'd prefer not to start dumping arbitrary SUID binaries all over the place.) So, that would probably only leave me with LDAP, checkpassword, and the FS dict backend. I can imagine how I could get LDAP to do this -- add some extra attribute for each user, and put together a simple script to change passwords, say, in Python, that would bind as the user and write the new password. However, this would require me to store the system user account database in LDAP, which is kind of overkill on at least one of the servers I want this setup on, where I know for certain that there won't ever be more than a handful of users. Checkpassword would probably work, too; perhaps by looking into some file in the user's $HOME or such. I'm not entirely certain about the security, or performance implications of that approach. With the FS dict backend, I could probably point it to a directory, in which every user would own a file containing their password, that no one else could write to. I haven't been able to find any more details about the structure of this directory hierarchy, though, or the contents of the individual files, so I don't know whether this is a viable approach, or not. My questions are, then: Is there some other way of implementing separate passwords that the users can set themselves that I'm overlooking? Is one of the three approaches described above a bad idea for some reason I don't see? Is there some kind of “standard solution” to this problem? The other thing I wanted to ask about is marginally related; I'd like to be able to allow users to customize the layout in which they store their mail. For instance, some users like to have their INBOX as an mbox in /var/mail, and other maildirs in ~/Maildirs/, others prefer having everything as a mix maildirs and mboxes in ~/mail, etc. Looking at the MailLocation wiki page, it seems like the only option, if I want to customize the location per user, is to set it in the userdb, but since we only have system users everywhere, it seems we have to use the passwd userdb, which doesn't support this kind of per-user customization (even on servers where PAM/NSS are configured to use LDAP). Again, am I overlooking something here? Is there nothing similar to ~/.imaprc, which is supported by certain versions of some other IMAP servers? Thanks in advance for any insights, Michal

Dovecot 1.2.15 and Convert Password Schemes
by Chuck Peters 11 Dec '15

11 Dec '15

Can I convert the password hashes with the older Dovecot? http://wiki2.dovecot.org/HowTo/ConvertPasswordSchemes shows how it can potentially be done with Dovecot 2.1, but when I try it with Dovecot 1.2.15, I'm not seeing a way to make it work. Any suggestions? This is an old Debian 6 system that's overdue for an upgrade. In the test environment upgrading OpenLDAP to Debian 8 I discovered most of our users passwords probably won't work. The hashes appear to be a old Unix DES based hash, ie base64 decoded ldif shows something like the following: userPassword:: {crypt}Aipcuzoh3eiVE Passwords stored in the SSHA hash seem to work fine. If given the password, a shell script could create the hashes with slappasswd and/or a SHA512 hash (using doveadm or mkpasswd) for use on Debian 8. # cat /usr/local/bin/dovecot-environment.sh #!/bin/sh set > /tmp/dovecot-environment exec /usr/lib/dovecot/imap "$@" I can show the /tmp/dovecot-environment if you like, but it's not showing the password as a variable... This system is using Debian's Dovecot package 1.2.15-7+deb6u1. Dovecot 2.1.7-7~bpo60+1 is available as a backport, but I would prefer not to upgrade Dovecot on the production system if I don't need to, or have some other reason such as some features for using IMAP for the migration. https://packages.debian.org/search?keywords=dovecot-common Thanks, Chuck # dovecot -n # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-686-bigmem i686 Debian 6.0.10 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s ssl_cert_file: /etc/lfrr/ca/thishost.crt ssl_key_file: /etc/lfrr/ca/thishost.key disable_plaintext_auth: no verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login verbose_proctitle: yes mail_privileged_group: mail mail_location: mbox:%h:INBOX=/var/mail/%Lu mbox_write_locks: fcntl dotlock mail_executable(default): /usr/local/bin/dovecot-environment.sh mail_executable(imap): /usr/local/bin/dovecot-environment.sh mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 pop3_reuse_xuidl(default): no pop3_reuse_xuidl(imap): no pop3_reuse_xuidl(pop3): yes auth default: mechanisms: plain login debug_passwords: yes passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf passdb: driver: pam args: session=yes dovecot userdb: driver: passwd args: /etc/passwd userdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf plugin: quota: dirsize quota_rule: *:storage=204800 I should note, I think the default_pass_scheme = CRYPT doesn't do anything with auth_bind = yes. # grep -v '^ *$#.*$\?$' /etc/dovecot/dovecot-ldap.conf hosts = 127.0.0.1 sasl_bind = no auth_bind = yes auth_bind_userdn = uid=%u,ou=People,dc=ccil,dc=org ldap_version = 3 base = ou=People,dc=ccil,dc=org pass_attrs = uid=user,userPassword=password,homeDirectory=userdb_home,uidNumber=userdb_uid,gidNumber=userdb_gid pass_filter = (&(objectClass=posixAccount)(uid=%u)) default_pass_scheme = CRYPT

autoexpunge creates special_use folder

11 Dec '15

namespace inbox { mailbox Spam { special_use = \Spam auto = create autoexpunge = 30d } } This creates the "Spam" folder in the filesystem on login/logout, even though it shouldn't. If I remove autoexpunge, the folder is not created. -- Tom Sommer

You can't have it here. Oh, yes. Thanks for pointing that out. By the way, what does it do? The wiki states mailbox_list_index=yes can help a lot by replying to IMAP STATUS (and similar) lookups from a single index without having to open each mailbox index separately. So it create an uber-index that combines information from individual indices? Are there any drawback to using this? > > 1) Do I need the special_user configuration at all?

Sieve script replication glitches
by Apollon Oikonomopoulos 09 Dec '15

09 Dec '15

Hi, I'm running a replicated setup on Debian with Dovecot 2.2.18 and Pigeonhole 0.4.8 and run into some glitches with sieve script syncing. Replication is implemented via DSync/doveadm over SSL. While e-mail replication works as expected, sieve script replication is not always successful. In general I have observed the following behaviour re. sieve script replication: - Sometimes sieve scripts are replicated but have an mtime of 0 (Jan 1 1970) on the destination. - Subsequent updates to these "bad" scripts are not replicated at all. - Sometimes after creating *another* sieve script (which may or may not get the correct timestamp), the "bad" script's timestamp/contents are corrected on the receiving side. The following is a minimal real-world example of what happens (including transaction log entries): 1. On the master create a new sieve script: cat test.sieve | doveadm sieve put -u user(a)example.com test1 Sieve storage on the master: -rw------- 1 vmail vmail 2001 Dec 9 15:53 test1.sieve Transaction log on the master: record: offset=44756, type=attribute-update (ext), size=72, modseq=514 - add: private/vendor/vendor.dovecot/pvt/server/sieve/files/test1 : timestamp=2015-12-09 15:53:28 value_len=0 record: offset=44828, type=modseq-update (ext), size=20 - uid=0 modseq=723 Sieve storage on the slave: -rw------- 1 vmail vmail 2001 Jan 1 1970 test1.sieve Transaction log on the slave: record: offset=55356, type=attribute-update (ext), size=72, modseq=597 - add: private/vendor/vendor.dovecot/pvt/server/sieve/files/test1 : timestamp=2015-12-09 15:53:29 value_len=0 record: offset=55428, type=attribute-update (sync), size=72, modseq=598 - add: private/vendor/vendor.dovecot/pvt/server/sieve/files/test1 : timestamp=2015-12-09 15:53:29 value_len=0 2.

The fact that it happens sometimes (around 30-40% of the time) likely indicates a race condition somewhere. Also I'm not at all sure sieve transactions should appear twice on the receiving side (ext and then sync); I see other entries (e.g. ext-intro) as a single "(ext) (sync)" record. Any ideas?
