Default Sub. of INBOX : false I thot that was going to sort it, alas it doesn't. Has it got something to do with the fact that kmail puts the contents of subfolders into a hidden directory in ~/Mail ? In kmail I have folders like: Forums, Newsletters, etc... These have subfolders, but in the file system it looks like: /home/rob/Mail/.Forums.directory/DCLUG/ instead of the expected: /home/rob/Mail/Forums/DCLUG/ Thanks for your help! /rob

[Dovecot] Dovecot, Squirrelmail and KMail
by Rob Thyssen 24 Jul '03

24 Jul '03

I just installed Dovecot and squirrelmail to read my email when I'm away from home. I subscribed to all the folders in my mail directory but I can't actually see any email. Is this a dovecot issue or a squirrelmail issue? I'm running KMail from KDE 3.1.2 and use Debian (Testing) on a Digital Alpha and installed both squirrelmail and dovecot using apt-get. I had to set 'default_mail_env = maildir:~/Mail' To get it to see the parent folders but I'm stuck there. Any advice appreciated. /rob

One way is to set default_realm and set the @domain for all users in passdb/userdb. Another way is to patch the code. Below is a patch for plaintext authentication. Or maybe I should make option that if given realm is default_realm, it would look up the user without the realm. I'm not sure if it's worth doing though. BTW. Your mail to dovecot-list got stuck at spamassassin. I raised the spam points a bit and lowered HTML mail's points a bit. Better would be if I could update SA's whitelist automatically when people subscribe. But I'm not really sure how to do that with mailman.

RE: [Dovecot] Hooks on folder operations

Hi Grahame, > Hi all, > > I'm interested in implementing an anti-spam system using > bayesian filtering. I had the idea of modifying and IMAP > server to assist in training the spam filter. Why do you want to hook it up into your imap server? I think it would be better to prevent emails to enter the mailbox with the MTA rather than removing it when the user is reading his email using imap. Why? Because the spam that is in the mailbox might push the user over his quota limit, and thus preventing legitimate emails to be delivered. > I was thinking of running a program whenever a message in > moved to the folder "Spam" or to a "Safe" folder.

With the new API code that Timo is making now, I guess this would be possible. (After all: if quota's are updated, something was written to the mailbox, or deleted of course!) > Anyway, if I were to write a patch to add support for running > an external program in these cases, would it be included?

You can always build a plugin, and plugins can be loaded whenever an administrator wants them to load. I don't know if Timo wants to include all plugins that are / will be written for dovecot, but I guess there might be a plugins part, where people can "post" their plugins so other people can benefit from them :) > Cheers > Grahame Kind regards, Maikel Verheijen

[Dovecot] Courier's IMAP custom flags implementation
by Timo Sirainen 23 Jul '03

23 Jul '03

Just thought to mention: http://dovecot.procontrol.fi/tmp/README.imapkeywords.html I'm not sure what to think of it. Good thing in it is that it doesn't limit the number of flags. Bad thing is that I think it's way too slow. Compared to Dovecot's implementation where I "steal" maildir flags a..z and treat them in the normal maildir way. Bad thing is obviously that it's limited to 26 different flags. And I really should fix that customflags file soon to be NFS-safe / read-lockless. It's just a bit problematic how to handle removing unused flags when you've hit the 26 limit and try to add new ones.

[Dovecot] Hooks on folder operations
by Grahame Bowland 23 Jul '03

23 Jul '03

Hi all, I'm interested in implementing an anti-spam system using bayesian filtering. I had the idea of modifying and IMAP server to assist in training the spam filter. I was thinking of running a program whenever a message in moved to the folder "Spam" or to a "Safe" folder. This could be easily added to the server as a generic feature, with hook programs for: * new message in a folder (either new, or moved into the folder) * message in folder is modified * message in folder is removed and so on. If the support was generic enough there could be many uses for it. Security of the external program needs to be considered but doesn't really affect the IMAP server itself. Anyway, if I were to write a patch to add support for running an external program in these cases, would it be included? Any feedback would be appreciated, if I'm going to do this I might as well do it in a way that can be integrated back into the main tree!

[Dovecot] Imap 2 imap copy tool?
by Maikel Verheijen 23 Jul '03

23 Jul '03

Hi List! At the moment, our company is preparing to migrate from MS-Exchange to a dovecot mail platform. Since there is no way to access the emails on the file-store other than using webmail, pop or imap, I wanted to do this by using an imap-to-imap copy tool. I have found one that does the job (but POORLY), named migrate (http://prdownloads.sourceforge.net/cyrus-utils/). Does anyone know some other tool(s) for me I could have a look at? My requirements for such software are: - it should use a username;password list to do the migration (20k+ users) - it should be able to do imap to imap copy, or imap to maildir with a flexible path - it should copy all the folders too, except the "Public Folders" from exchange. - it has to be able to "ignore" unknown flags from the exchange imap server (\Recent). What I would love the software to have (and what imapmigrate lacks): - Folder and message syncing (to be able to keep the mailbox in sync) - detailed errors if something goes wrong, not too much fuss over accounts that DO get copied cleanly - fast tool? :) Thank you for your time! Kind regards, Maikel Verheijen.

[Dovecot] hierarchy_sep
by molter＠tin.it 22 Jul '03

22 Jul '03

Hi Timo, I would like to add another naming scheme to dovecot to recognize maildir folders: As of today: ~/Maildir/.foo ~/Maildir/.foo.bar I would like to add: ~/Maildir/foo ~/Maildir/foo/bar I had a quick look at the code (very clean, I am impressed!) and I saw struct mail_storage, with field hierarchy_sep. I think I cannot just set hierarchy_sep to '/', because /foo would start from the root of the filesystem instead of being relative to ~/Maildir. Do you have any suggestions on the cleaner way of doing it? Or maybe do you think it is wrong to depart from '.' for some reason? thanks Marco
