[Dovecot] A new director service in v2.0 for NFS installations
by Timo Sirainen 16 Jun '10

16 Jun '10

As http://wiki.dovecot.org/NFS describes, the main problem with NFS has always been caching problems. One NFS client changes two files, but another NFS client sees only one of the changes, which Dovecot then assumes is caused by corruption. The recommended solution has always been to redirect the same user to only a single server at the same time. User doesn't have to be permanently assigned there, but as long as a server has some of user's files cached, it should be the only server accessing the user's mailbox. Recently I was thinking about a way to make this possible with an SQL database: http://dovecot.org/list/dovecot/2010-January/046112.html The company here in Italy didn't really like such idea, so I thought about making it more transparent and simpler to manage. The result is a new "director" service, which does basically the same thing, except without SQL database. The idea is that your load balancer can redirect connections to one or more Dovecot proxies, which internally then figure out where the user should go. So the proxies act kind of like a secondary load balancer layer. When a connection from a newly seen user arrives, it gets assigned to a mail server according to a function: host = vhosts[ md5(username) mod vhosts_count ] This way all of the proxies assign the same user to the same host without having to talk to each others. The vhosts[] is basically an array of hosts, except each host is initially listed there 100 times (vhost count=100). This vhost count can then be increased or decreased as necessary to change the host's load, probably automatically in future. The problem is then of course that if (v)hosts are added or removed, the above function will return a different host than was previously used for the same user. That's why there is also an in-memory database that keeps track of username -> (hostname, timestamp) mappings. Every new connection from user refreshes the timestamp. Also existing connections refresh the timestamp every n minutes. Once all connections are gone, the timestamp expires and the user is removed from database. The final problem then is how multiple proxies synchronize their state. The proxies connect to each others forming a connection ring. For example with 4 proxies the connections would go like A -> B -> C -> A. Each time a user is added/refreshed, a notification is sent to both directions in the ring (e.g. B sends to A and C), which in turn forward it until it reaches a server that has already seen it. This way if a proxy dies (or just hangs for a few seconds), the other proxies still get the changes without waiting for it to timeout. Host changes are replicated in the same way. It's possible that two connections from a user arrive to different proxies while (v)hosts are being added/removed. It's also possible that only one of the proxies has seen the host change. So the proxies could redirect users to different servers during that time. This can be prevented by doing a ring-wide sync, during which all proxies delay assigning hostnames to new users. This delay shouldn't be too bad because a) they should happen rarely, b) it should be over quickly, c) users already in database can still be redirected during the sync. The main complexity here comes from how to handle proxy server failures in different situations. Those are less interesting to describe and I haven't yet implemented all of it, so let's just assume that in future it all works perfectly. :) I was also thinking about writing a test program to simulate the director failures to make sure it all works. Finally, there are the doveadm commands that can be used to: 1) List the director status: # doveadm director status mail server ip vhosts users 11.22.3.44 100 1312 12.33.4.55 50 1424 1) Add a new mail server (defaults are in dovecot.conf): # doveadm director add 1.2.3.4 2) Change a mail server's vhost count to alter its connection count (also works during adding): # doveadm director add 1.2.3.4 50 3) Remove a mail server completely (because it's down): # doveadm director remove 1.2.3.4 If you want to slowly get users away from a specific server, you can assign its vhost count to 0 and wait for its user count to drop to zero. If the server is still working while "doveadm director remove" is called, new connections from the users in that server are going to other servers while the old ones are still being handled.

[Dovecot] Sieve doesn't appear to be active
by Darek M 16 Jun '10

16 Jun '10

I'm hoping that this isn't something stupid and that I'm not wasting bandwidth here, but I'm stuck and don't know any further ways of debugging this. And most non-documentation, end-user created info I find is for 1.0 with cmusieve. Running Dovecot 1.2.11 on Fedora Core 12. Added 'sieve' to 'mail_plugins'. Have enabled verbose logging with 'mail_debug = yes'. But I'm not seeing anything in the logs relating to sieve, and the sieve script I point to isn't being compiled (no .log file). Everything else works fine, this is a production system where I'm trying to add sieve support. What steps can I take to troubleshoot?

Hi: When runs dovecot, I can see that dovecot sends two ldap queries to my OpenLDAP server and establishes one conection, however when test my dovecot-ldap configurarion with telnet My OpenLDAP server don't received ldap request from my clients. dovecot-auth process need special permissions?. my dovecot-ldap.conf file is wrong?.

[Dovecot] passwd-file management utility
by Phil Howard 15 Jun '10

15 Jun '10

I'm now putting together tools/documentation to manage/administer the mail server, including, of course, managing users. Round one will be command line tools. In order to avoid re-invention, I was looking around for existing tools. I really cannot find any. So it seems I will be developing them. The first will be the one to manage users in the passwd-file format. So I'm just asking around if anyone has heard of such tools somewhere Google isn't finding (it does find lots of generic pages with the keywords used in other contexts). If not, I'll be building my own (and this will be for passwd-file format for the userdb/passdb),

[Dovecot] Maildir + /var/mail

Hi, I have just switched to Maildir, and I have noticed something. Even though it works properly, I have noticed that a file named /var/mail/user with 0 bytes length is still created. Is this normal? I use sendmail+procmail+dovecot. I have also tried the combined procmail+deliver approach with the same results. I also use a global /etc/procmailrc. Thank you
