[Dovecot] Dovecot NFS Indexes and IMAP Migration
by Andy Dills 29 Feb '08

29 Feb '08

Hi there, After being extremely impressed from implementing it in some customer installations, I've decided to migrate our mail infrastructure to dovecot. Being able to have /bin/checkpassword support across the board for pop, imap, and smtp authentication, as well as being able to ditch stunnel for the SSL layer...where were you in 2001?!? :) I have two concerns, the first is about the proper index configuration in our environment, and the second is about the best way to migrate mailboxes. Some quick background: we've long been distributed, with an L4 switch up front and a Netapp in the back, Mysql for metadata. We have a cluster of several FreeBSD boxes doing filtering and maildir delivery (postfix/amavisd-new), and we have a server that users get sent to for pop/imap. If it's down, they get sent to one of the filter boxes instead. So, regarding the indexes: >From reading the docs, it appears I would not be able to use the dovecot LDA due to locking issues (bummer), and I should configure dovecot to store index files on a local disk of the primary pop/imap server rather than on the netapp. My first question would be, how much of a performance hit should I expect from having to update the indexes when mail is checked rather then when mail is delivered since I can't use the LDA? Is this a minor issue like I expect, or can it be something the user actually notices when checking mail? In a worst case scenario, if the pop/imap server is down, and another server is used, how long would it take to create an index for an account with a few hundered megs, several thousand messages? I'm wondering if, since I have plenty of overhead available on the netapp, I should just store the indexes there in case another server must be used. I'm basically looking for more information about the pros and cons of storing the indexes on the nfs volume in a situation where a single server would normally be providing pop/imap service. Regarding migration: My concerns regarding migration relate to how best to process existing maildirs by both converting the previous imap metadata and calculating an initial index for each account. First off, I can't seem to find any info on a way to create an initial index file for all of the mailboxes. Can anybody suggest a command I can use for this? I'm sure I just overlooked it. Regarding the migrations, we have both courier and bincimap to deal with. (We use qmail's pop, so no complications with migrating courier). Fortunately, courier is used for normal imap on 143, bincimap is only used for webmail. So, it would seem that metadata from bincimap could be ignored; the only thing it would seem important to preserve is mailbox subscriptions. Please correct this assumption if I'm wrong. bincimap uses a INBOX/folder format in the subscription file, however the actual folders are stored exactly the same as the INBOX.folder style of courier. So, it seems like my best option is to modify the courier-dovecot-migrate.pl script to consider the mailboxes subscribed to via bincimap. Here's a modified convert_subscriptions that seems to work well in limited testing, feel free to point out any idiot mistakes, it's been a while since I've done anything substantial in perl. I would have sent a patch but I suspect I'm the only person who will ever use this change and critiquing it would be easier with a full context. sub convert_subscriptions { my ($dir, $owner_uid, $owner_gid) = @_; my $in_fname = "$dir/courierimapsubscribed"; # ADDED: The bincimap file to parse my $in_fname2 = "$dir/.bincimap-subscribed"; my $out_fname = "$dir/subscriptions"; # MODIFIED: Return only if neither exist return if (!-f $in_fname && !-f $in_fname2); if (!$overwrite && -f $out_fname) { print "$out_fname already exists, not overwritten\n" if (!$quiet); return; } return if (!$do_conversion); my ($fin, $fin2, $fout); open ($fin, $in_fname) || die $!; open ($fin2, $in_fname2) || die $!; open ($fout, ">$out_fname") || die $!; # ADDED: An array to track mailboxes we've written in case both files exist my @subs; while (<$fin>) { chomp $_; if (/^INBOX$/i) { print $fout "INBOX\n"; push @subs, "INBOX\n"; } elsif (/^INBOX\.(.*)$/i) { print $fout "$1\n"; push @subs, "$1\n"; } else { # unknown. keep it as-is. print $fout "$_\n"; push @subs, "$_\n"; } } close $fin; # ADDED: A second loop, same as the first, but also checking to make # sure that the mailbox has not already been written to the new file to # eliminate duplicates. while (<$fin2>) { chomp $_; my $sub = $_; if (/^INBOX$/i && !grep (/^INBOX\n/i, @subs)) { print $fout "INBOX\n"; } elsif (/^INBOX\/(.*)$/i && !grep (/^$1\n/i, @subs)) { print $fout "$1\n"; } elsif (!grep(/^$sub\n/, @subs)) { # unknown. keep it as-is. print $fout "$sub\n"; } } close $fin; close $fin2; close $fout; chown $owner_uid, $owner_gid, $out_fname; } Thanks in advance for any help or suggestions!

[Dovecot] cram-md5 crashes passdb

Hi all, When setting auth mechanisms: plain login cram-md5 and only having pam passdb and passwd userdb. dovecot nevers starts and crashes reporting: Feb 29 10:19:41 pitux-clust-op1 dovecot: Dovecot v1.0.10 starting up Feb 29 10:19:41 pitux-clust-op1 dovecot: auth(default): CRAM-MD5 mechanism can't be supported with given passdbs Feb 29 10:19:41 pitux-clust-op1 dovecot: Auth process died too early - shutting down Feb 29 10:19:41 pitux-clust-op1 dovecot: child 24722 (auth) returned error 89 Removing crom-md5 from auth mechanisms solves the problem. Adding another passdb (like vpopmail) alsos solves the problem. Any clue ?

[Dovecot] imaptest update
by Timo Sirainen 29 Feb '08

29 Feb '08

I've finally added support for "normal" command/reply tests for my imaptest program (http://imapwiki.org/ImapTest) My plan is that imaptest will include some generic IMAP compliancy tests and Dovecot will include some more strict Dovecot-specific checks. "make dist" will run all these tests before building a tarball, so in future I shouldn't be able to release horribly broken versions. :) I haven't yet had time to implement all the features that I'd like (e.g. unordered list handling needs support), but I think the current features will allow testing quite a lot already. http://imapwiki.org/ImapTest/Tests explains how it works. There are currently two files: the actual test file and *.mbox file where the mails are appended from to the test mailbox. I'm going to also add *.conf file which allows specifying specific dovecot.conf settings. This way I can test all these different namespace (etc.) variations as well. A couple of examples to show what's possible: # Check that EXAMINE and STATUS return same UIDVALIDITY examine $mailbox * ok [uidvalidity $uidvalidity] ok [read-only] ok status $mailbox (uidvalidity) * status $mailbox (uidvalidity $uidvalidity) # Test EXPUNGE handling with 2 connections: connections: 2 1 ok fetch * uid * $seq fetch (uid $uid) 1 ok store $seq flags \deleted * $seq fetch (flags (\deleted \recent)) 1 ok expunge * $seq expunge 2 ok fetch $seq uid * $seq fetch (uid $uid) 2 ok noop * $seq expunge # LIST testing: state: auth ok list "" "" * list (\noselect) $sep "" # "" means that delete can return anything # (although restricting it to "ok" or "no" would be better) delete $mailbox${sep}test "" delete $mailbox${sep}test2 "" ok create $mailbox${sep}test ok create $mailbox${sep}test2 ok list "" $mailbox$sep% * list (\hasnochildren) $sep $mailbox${sep}test * list (\hasnochildren) $sep $mailbox${sep}test2

[Dovecot] "too little data" error still occurring in 1.0.10
by Mike Brown 28 Feb '08

28 Feb '08

Greetings- I'm running dovecot 1.0.10, but am seeing the "too little data" error that was supposedly fixed in 1.0.9. Not sure how long it's been going on. I have a straightforward mbox setup, and am using Thunderbird to check my inbox. It can't read the box. The log fills up with these messages: Feb 8 23:24:43 chilled dovecot: imap-login: Login: user=<mike>, method=PLAIN, rip=##.##.##.##, lip=##.##.##.##, TLS Feb 8 23:24:43 chilled dovecot: IMAP(mike): FETCH for mailbox INBOX UID 1644 got too little data: 4254 vs 4262 Feb 8 23:24:43 chilled dovecot: IMAP(mike): Disconnected: Disconnected Let me know if there's more info needed. -Mike

[Dovecot] Optional Sieve includes
by Anders 27 Feb '08

27 Feb '08

I (think that I) want a global Sieve setup like this: require ["include"]; include :global "spam.sieve"; include :personal "folders.sieve"; include :personal "vacation.sieve"; ... that does not fail if a user has not created the personal filters. Any ideas how to do something like that? I read the source, but it seems that a failed include will exit the Sieve, so the above will not work. Incidentally, I think I found a typo, so a patch is below.

[Dovecot] Auth_cache not working?
by Jan van den Berg 27 Feb '08

27 Feb '08

Hi, I have: auth_cache_size = 4096 auth_cache_ttl = 3600 I use Thunderbird connecting to my Dovecot IMAP server 1.1rc1. I click on five folders and close Thunderbird. This is my log: dovecot: Feb 27 17:26:56 Info: Dovecot v1.1.rc1 starting up dovecot: Feb 27 17:26:56 Info: auth-worker(default): mysql: Connected to auth01 (Auth) dovecot: Feb 27 17:27:07 Info: imap-login: Login: user=<roka-05>, method=PLAIN, rip=10.4.32.70, lip=10.4.32.235 dovecot: Feb 27 17:27:08 Info: imap-login: Login: user=<roka-05>, method=PLAIN, rip=10.4.32.70, lip=10.4.32.235 dovecot: Feb 27 17:27:10 Info: imap-login: Login: user=<roka-05>, method=PLAIN, rip=10.4.32.70, lip=10.4.32.235 dovecot: Feb 27 17:27:11 Info: imap-login: Login: user=<roka-05>, method=PLAIN, rip=10.4.32.70, lip=10.4.32.235 dovecot: Feb 27 17:27:13 Info: imap-login: Login: user=<roka-05>, method=PLAIN, rip=10.4.32.70, lip=10.4.32.235 dovecot: Feb 27 17:27:20 Info: IMAP(roka-05): Disconnected: Logged out bytes=83/469 dovecot: Feb 27 17:27:20 Info: IMAP(roka-05): Disconnected: Logged out bytes=106/524 dovecot: Feb 27 17:27:20 Info: IMAP(roka-05): Disconnected: Logged out bytes=71/463 dovecot: Feb 27 17:27:20 Info: IMAP(roka-05): Disconnected: Logged out bytes=356/4887 dovecot: Feb 27 17:27:20 Info: IMAP(roka-05): Disconnected: Logged out bytes=147/939 In Outlook Express: dovecot: Feb 27 17:27:38 Info: imap-login: Login: user=<roka-05>, method=PLAIN, rip=10.4.32.70, lip=10.4.32.235 dovecot: Feb 27 17:27:38 Info: IMAP(roka-05): Disconnected in IDLE bytes=65/112 dovecot: Feb 27 17:27:38 Info: imap-login: Login: user=<roka-05>, method=PLAIN, rip=10.4.32.70, lip=10.4.32.235 dovecot: Feb 27 17:27:38 Info: IMAP(roka-05): Disconnected in IDLE bytes=259/1098 dovecot: Feb 27 17:27:44 Info: imap-login: Login: user=<roka-05>, method=PLAIN, rip=10.4.32.70, lip=10.4.32.235 dovecot: Feb 27 17:27:51 Info: IMAP(roka-05): Disconnected: Logged out bytes=1682/10349 Sort of the same thing: but more inconsistent. Sometimes I click five folders and OE will have done 3 logins sometimes 2. So new IMAP logins for (more or less) every click in Thunderbird and OE; this is what auth_cache_size should solve right? Am I applying the auth_cache_* variables wrong or is something else wrong? Cheers, Jan
