We recently switched from POP3 Outlook Express to IMAP using IMAP-UW Thunderbird. Personally I have had no issues with IMAP-UW, but the users in our office have had issues with the mbox format itself. Specifically they cannot store messages subfolders within a folder (referring to the Thunderbird definition of a folder). In mbox, since a given folder is not a directory, but a file, you cannot place a subfolder within that file. Outlook Express' POP3 implementation did not have this behavior. Right or wrong, my users have requested that I attempt to restore this functionality in IMAP. Am I correct in assuming that if I switch to a mdir format server, it will operate in the manner they are requesting? My next question is in regards to scalability, not so much in the way of users, but in the amount of mail they store. Currently we have about 20 email accounts, and for the most part the users keep their email to a reasonable amount. However I do have 5 users that insist they save everything, and do not clean out their InBoxes. Currently they retain email going back 5 years, and have mail folders in excess of a couple of gigs apiece. Since one of these people is the owner, I have little chance of changing this policy. However they are asking that I attempt to increase the response time of the IMAP server, which can be somewhat slow for them - especially through SquirrelMail. Would the mdir format help in this situation as well? Last question, how difficult is it to back up the mdir format? Currently I cron a tar job, nightly, to backup the mboxes to another server to allow for tape backups (the tape unit on the server in question doesn't want to play nice with FreeBSD), and have had no difficulty in accomplishing this. Can I accomplish the same style of backups when moving to mdir? I'm in the middle of setting up a server to try out various IMAP servers to test which would provide the best response for our specific needs (low number of users - high volume of saved email), and would appreciate any opinions on the matter as it would probably save considerable time picking the right software to begin with.

I switched my main production mail server from imap-uw to dovecot about a year ago and have been much happier since. It is very stable, and handles large folders and concurrent connections to the same account very smoothly (both things I had issues with using imap-uw). I think that dovecot's betas are like other products' release candidates--I've never had the sense that I'm using beta software. It also supports shared folders, although I haven't had a need to experiment with that.

Re: IMAP server alternatives

I think it does not, but I do not need it. I can use postfix and
mydestination, virtual_maps. This is enough for me.
Any tips on migration?
Yes, it looks easy. I created these namespaces in dovecot.conf:
namespace private {
separator = /
inbox = yes
hidden = yes
prefix = #mbox/
location = mbox:/home/%u:INBOX=/var/mail/%u
}
namespace private {
separator = /
prefix = oldsystem/
location = mbox:/home/%u
}
namespace private {
separator = /
prefix =
location = maildir:/home/%u/Maildir
}
The first one allows the old mbox format inbox to be used from
/var/mail/username. (I could have recompiled procmail in order to
deliver to maildir...)
The second one allow the users to view their old mbox style folders.
They can move the messages to the new maildir format, if they wish.
(Drag and drop in thunderbird...) Later I can delete the old mbox folders.
The third one is the default namespace (without name) and it has the new
maildir format.
Best,
Laszlo

How did you handle the transition from mbox to maildir? -jav For my POP users, I didn't. I leave everyone's 'inbox' in /var/mail in mbox format. If a user connects via IMAP (Squirrelmail, etc.), folders in /home/%u are created and stored in maildir format, but their inbox stays in /var/mail in mbox format. See Multiple Mailbox Locations: http://wiki.dovecot.org/Namespaces Dovecot also comes with convert-tool. For the users who had mbox files in their home directory, I used it to convert those to maildir format. I don't think the port installs convert-tool; I got it by doing 'make' in the dovecot port directory and manually copied it from there.

It is not dovecot or courier issue. I have both courier and dovecot working in parallel on the same mail store. The dovecot is currently just for testing and the courier is in production (for the last 4 years or more). We store the domain as part of the user name in a custom ldap database and courier and dovecot have no issues interfacing with it with the proper config.
