[Dovecot] General performance of RC5
Hi all, Switiching to RC5, there is a visible decrease in performance to access via IMAP large accounts (>1G) with mutiple mailboxes per accounts. In RC4, there was no delay visible by a human when accessing locally. Now it takes up to 4 or 5 secs. (running on OpenSuse, mysql 5.1.35 for auth, dbox as back end) Anybody experienced also this ? Thanks Joan
[Dovecot] Mailbox isn't a valid mbox file
Getting "Mailbox isn't a valid mbox file" on 1.2rc2 after transferring mail from an ancient 0.99.13 system. The first line of the file looks ok. Curiously, it's one of my archival folders of this list. Here's the first header from the top of the file: From tss at iki.fi Sat May 1 21:48:17 2004 From: tss at iki.fi (Timo Sirainen) Date: Sat May 1 21:54:18 2004 Subject: [Dovecot] 1.0-test2 released Message-ID: <1083437297.21296.19.ca...@hurina> X-IMAPbase: 108532 20128 Status: RO X-UID: 14065 Content-Length: 226989 X-Keywords: It would be nice if the code that verified the mailbox format would log details about what it disliked.
Re: [Dovecot] Dovecot + FreeBSD-7.2 + ZFS ?
We use this at work on a fairly busy server with about 1300 email accounts. I also use this configuration for my personal server. It works great, I don't know if you've been using ZFS on 7.0 or 7.1 but with 7.2 a lot of nasty things are fixed and it is very stable. On earlier versions of FreeBSD with ZFS you needed mmap_disable = yes in your dovecot.conf or the index files would get corrupted but that has long since been fixed. I don't know how comfortable you are with FreeBSD but if the answer is very you should seriously look in to either checking out RELENG_7 (optimal) or grabbing this source http://svn.freebsd.org/base/user/kmacy/releng_7_2_zfs/ (use subversion-freebsd port, keep in mind you wont be able to update your source with csup to patch 7.2 because you will end up with an older zpool version, you'll need to apply future patches to 7.2 manually). The ladder is 7.2-RELEASE with the special ZFS v13 code that was recently committed. I can tell you with confidence this runs much better than the ZFS v6 stuff in the stock 7.2-RELEASE. We have moved almost everything over to it and it is absolutely beautiful. You also get all the newer zfs dataset features in the v13 stuff (like being able to assign l2 arc cache devices, say a really fast ssd to cache maildirs).

Personally, I use different system users on the IMAP server with similar
setups. Since in your case there is no local MTA involved, which is part
of the picture here...
The best thing about different accounts is, that (per-account) default
sender addresses and options just work.

[Dovecot] Multiple mail locations for a single user
Hi, I use offlineimap to cache my remote IMAP mail for my multiple accounts (personal, work, etc) to several maildirs locally. At the moment in my mail client I'm using Dovecot to access one of the maildirs via IMAP, and then direct maildir access for the others. This is suboptimal however because my clients direct maildir support isn't great. Is there any way to let me access all three maildirs through dovecot? I'm guessing that I can do this with namespaces but I'm not sure. Any suggestions and pointers?

Hello Anyons has tested this configuration with success ? I'll test it in few days and I am wondering if I am alone :-) Thanks
