Re: [Dovecot] Cyrus MailDir to Dovecot mbox

Timo,
Thanks again for the tip on the convert-tool. That did work to
convert this guys 121K worth of messages. The built in convert plugin
with dovecot was not able to do it. I believe due to the fact that this
guy has folders with messages and then sub-folders with more messages.
I'm migrating to mbox format which doesn't allow that feature. The
convert-tool showed me this and it was easy fix to just move all
sub-folders up to a flat directory structure. Then the convert-tool
ripped right through all the messages.

Thanks. The cyrus2dovecot looks to have worked. So if I understand
the process I now just move the MailDir folder that was created to the
users home directory on our mail server. I will try the dovecot convert
plugin. Just make sure I'm doing this correct in the config file:
If you do it only once, you don't need to use convert plugin. There's
also a convert-tool binary included.
mail_location = mbox:~/:INBOX=/userM/mail/%u
protocol imap {
mail_plugins = convert
}
plugin {
convert_mail = Maildir:~/Maildir:INBOX=/userM/mail/%u
}
Is this correct? The example on the website only shows how to convert
from mbox to MailDir.
That looks also correct.

I guess it depends on the size of your mails. With mboxes it can be used only with read-only archives, so it's not all that useful. With maildir it can be used transparently with read-write mailboxes. I've no idea what the performance difference or space improvements are. I guess that'll also depend on your system. I use zlib compressed maildirs on my primary server (12000+ users) and it achieves average compression ratio of 1.8, so if your system is io-bound you can spend some cpu cycles to significantly decrease disk load. But is that 1.8 in bytes or disk blocks? Bytes. Or does it make much of a difference either way? Does 2x less space per message even matter with small messages since most disk I/O probably goes to seeking, so reading a single 4 kB message takes pretty much the same time as a 8 kB message? Yes, for small messages it's not very usefull, but multimegabyte mails are quite common nowadays and for them compression is a clear win. Also I remember that load average decreased when I started to use message compression. I have no real numbers now, but it was noticeable. -- Andrey Panin| Linux and UNIX system administrator [EMAIL PROTECTED] | PGP key: wwwkeys.pgp.net signature.asc Description: Digital signature

[Dovecot] dovecot 1.2: dict no longer really support DICT_ITERATE_FLAG_RECURSE
Hi, In dovecot 1.1, I could use DICT_ITERATE_FLAG_RECURSE when iterating over a dict to retrieve all entries that start with a given prefix. This doesn't seem to work anymore in the new dict implementation in dovecot 1.2. Looking at the SQL queries actually generated, it seems as if dovecot 1.1 used to generate queries that use pattern matching (key LIKE my/prefix/%) whereas dovecot 1.2 does not, so it's no wonder that it doesn't work in 1.2. This probably has to do with the pattern matching for dict keys in the config file. It would be enough for my purposes at the moment -- i.e. getting the metadata plugin to work with dovecot 1.2 -- if recursion were only possible for the last of fields in the pattern.

Re: [Dovecot] 1.1.4 and trouble over NFS
That looks correct. So either something's changed in Dovecot since I last tested it with NFS, or something's changed in Linux kernel. Or there's something else weird going on. I don't really have any good suggestions for solutions and I don't really have time to debug NFS problems right now.. Or you could of course always try if disabling NFS attribute cache fixes things, but that'll most likely also make your performance a lot worse. Fwiw I just upgraded one of our servers from 1.1.2 to 1.1.4 (32-bit, centos5.2) and cant see any changes in our nfs access patterns. We use nfs3 though. Mark
[Dovecot] Request for help with new plugin
Hi there, I was having lots of trouble with the normal expire plugin so I decided to try and come up with a plugin that handles the trash directory in the same way as Courier (when the user logs out it should clean messages from the trash that have been there for more than X days.) I used the expire and trash plugins as a guide but there are probably a number of things done wrong here and I have plenty of questions. To use this you'd need to run autoreconf for the autotools scripts, compile, make, make install, then add autoexpire to the imap/pop3 mail_plugins lists and autoexpire = Trash 7 to the plugin section. 1. Is there any documentation of how the hook system and virtual mailboxes work outside of the source code? 2. I'd like the Trash cleanup to occur at logout, but the closest I could find was mailbox close. This makes the behavior a little quirky. It seems like Dovecot closes the mailbox each time it performs an operation on it, so when the client gets a list of mail in the box it does a close and the oldest items in the returned list will actually be expunged. 3. Is SAVE_DATE the correct field to be looking for here? I want the expiration to be based on the amount of time the letter has spent in the trash folder. 4. For searching through the Trash folder, SEARCH_BEFORE doesn't seem to match up with SAVE_DATE. Is there some other way to limit the search results to the dates that will fall before a certain SAVE_DATE value? J.D. dovecot-autoexpire-plugin.diff Description: Binary data

I remember thinking about this and I thought I did something similar.
What kind of dict keys/configuration do you need now?
I currently use a configuration like this:
map {
table = dict
pattern = shared/$key
value_field = value
username_field = username
fields {
key = $key
}
}
There's a similar entry for a priv/$key pattern. This was the most obvious
way of getting the metadata plugin to work with dovecot 1.2.
key contains the mailbox name followed by the annotation name. When doing a
recursive iteration, the key only contains the mailbox name and thus the
iteration returns all the annotations for a given mailbox. That's how it
worked with dovecot 1.1 anyway.
The way the mailbox and annotation name are translated into a dict key is not
ideal, but I'd prefer to get the annotations working with 1.2 before trying
to improve this (e.g. so that the pattern could become somethng like
shared/$mailbox/$key).

Re: [Dovecot] Test environment question
I have a call open to IBM with their Compiler group on this to see if this can't be fixed right.

In Thunderbird there's a setting which specifies how many connections it can use.
Re: [Dovecot] Test environment question
The code has some checks that if posix_fallocate() fails with a specific errno it stops trying to use it. Maybe it hits that condition at some point. Or maybe the code just isn't called for some reason, I don't really know..

Re: [Dovecot] Cyrus MailDir to Dovecot mbox
On 10/9/2008 12:08 PM, CJ Keist wrote: Charles, It's to do with how our current file services are setup and a personal preference and familiarity with the mbox format. Right now other than users inboxes, all mail folders are stored in the users home directory on central file server which the mail server mounts via NFS. Maildir is a big change from mbox and would give a confusing view to users that decided to look into their Maildir folder. I don't even want to think about what they might try mucking around with in there ;). mbox format is just cleaner and users can easily see that these are the same folders they see on their mail client. shudder I wouldn't be able to sleep at night if my users' mail was directly accessible by the users... ;) But if I ever get the money to add enough local disk storage on our mail server and can move all users mail folders to the mail server, is when I would probably think about switching over to the Maildir format. This way the users only way to access their Maildir folder would be through a mail client. I feel your pain... -- Best regards, Charles
