[2.3 feature request]: multiple passwords for single user
by Arkadiusz Miśkiewicz 15 Dec '14

15 Dec '14

Hi. I wonder if there any plans of finishing "multiple passwords for single user" feature? Few months old thread mentioned this: http://www.dovecot.org/list/dovecot/2014-July/097217.html and even a patch that unfortunately was never finished http://dovecot.org/patches/2.0/auth-multi-password-2.0.diff Multiple passwords for single user are great since allow easy password management for users. For example you could have one password on a laptop, one on a phone, one on a tablet. Revoking access to the device is as easy as dropping single password and it doesn't affect other devices. There are more use cases. Untill that happens (not that great) workaround exists: http://wiki2.dovecot.org/Authentication/MultipleDatabases Thanks, -- Arkadiusz Miśkiewicz, arekm / ( maven.pl | pld-linux.org )

Userdb's and IMAP proxying
by Thomas HUMMEL 15 Dec '14

15 Dec '14

Hello Timo, In order to plan a migration, I want to setup an IMAP proxy (proxy_maybe) with a dovecot server (I'm running the old dovecot-2.1.15 but I could upgrade or use a proxy only dovecot-2.2.x server)/LDAP pass et userdb's. I'm won't be in charge of the migration itself but I think the idea will be to migrate a chunk of users each night and then let the proxy send them to the new server. I wonder if, instead of altering my LDAP schema to be able to add the needed attributes (matching proxy/proxy_maybe, host, ...) I could use a second userdb (preferably in a file : passwd-file ?) only for those extra_fields (i.e. the second userdb would extend the LDAP one). As a matter of fact, I guess those who will migrate users will prefer writing to a file than to add some LDAP attribute in the user entry. In other words, can I get different extra_fields for the same user in different userdb's ? -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Groupe Exploitation et Infrastructure

Replication and Sieve

Hi, I've got two servers set up for replication, which is working fine - except the sieve scripts. While the first replication, the existing rules have been replicated well. Also the activation/Deactivation seems to work. But Changes to the rules doesn't seem to be transferred.

Can't save to folders
by Dave G. 15 Dec '14

15 Dec '14

When I login through imap, I can see everything in ~/mail/ just fine. I cannot save to any of them. If I have an autocreate-autosubscribe folder (ZZZ here), it shows up as empty (correct). Then if I save something to it through imap, a file ~/mail/ZZZ appears, but nothing actually gets saved to it.

Is the mdbox format backwards compatible?
by Orion Poplawski 12 Dec '14

12 Dec '14

I'm contemplating using dsync with dovecot-2.2.10 (el7) and then transferring the resulting mdbox files to a dovecot-2.0.9 (el6) server. Is the mdbox format backwards compatible between the two versions?

stacking istreams and ostreams
by Philipp Brüll 12 Dec '14

12 Dec '14

Hello, I'm developing an encryption plugin for dovecot and ran into a problem with the stacking of i/o-streams. The encryption i/o-streams are working fine on any kind of mail the test suite is passing through them. But as soon as the zlib plugin is enabled the logs show an cache error: failed: Cached message size larger than expected (214 > 206, box=INBOX, UID=1) I've already double-checked the return values of ostream's sendv and istream's read function. They seem correct (and equal). If the order of the streams are changed (by changing the number in the lib-filename libxx_scrambler.so); meaning that the encryption is done before the compression (which isn't efficient) both streams are working correct without any errors. Is there some way the zlib plugin changes the cached message size? Is there some behaviour of the zlib plugin that I'm missing? Any help would be very welcome.
