[Dovecot] 1.0-test15 released
by Timo Sirainen 15 Jun '04

15 Jun '04

http://dovecot.org/test/ Maildir code is still having syncing trouble. I thought about fixing mbox code for a chance - if the same problems happen with it too then I at least know that the problems are in indexes instead of maildir syncing itself. So, the biggest change in 1.0-test15 is a new fully functional superfast mbox code. If you can make it corrupt your mboxes I'd like to know about that. I haven't tested it too much yet, but I haven't seen corruption for a while anymore. Superfast as in: - Syncing and modifying the mbox is done in one integrated loop, no more passing through the whole mbox multiple times. - If we know the mbox is synced and we need to modify it, we directly jump to the message(s) needing modification and change only them. This means that with upcoming Dovecot LDA the mbox never needs to be fully parsed. As long as you're not expunging old messages, mboxes with sizes of even gigabytes should be no problem. Still a few remaining issues though: - It gets to infinite loop with 0 sized message body. I'll fix this soon - Recent counters are broken - mbox lock should be kept two extra seconds after syncing. that is required so that we can be sure no-one else has modified the mbox (ie. mtime changes every time) - APPEND command doesn't yet update indexes directly, so they still trigger a full sync - keywords aren't implemented - UW-IMAP style "FOLDER INTERNAL DATA" message is almost supported.. but not quite yet. We're going to use it if it exists, but we won't insert one ourself. This also brings to my mind supporting some other flatfile formats.. Well, I'll write another mail about that.

[Dovecot] PAM_RHOST item
by Tom Alsberg 15 Jun '04

15 Jun '04

A little problem, which is bugging me: when using PAM authentication, Dovecot (0.99.5) does not set the PAM_RHOST item, so the PAM modules cannot know who the client is. We need this for some PAM module doing access control. Changing passdb-pam.c to pam_set_item it seems trivial, but I'm bugged as to how to get the client name from there. It seems not to be available in the auth_request strut or anything from there. I tried even adding an upwards reference from there to the struct client *, but then I see that there are three structs named client and two structs named auth_request, and somehow I got into trouble of passing it cleanly. Any help or guidance for it is greatly appreciated. (I know Dovecot 0.99 is not really under development and such stuff is done in Dovecot 1.0 now, but that's not yet stable and for now we're using 0.99 where it would help).

[Dovecot] Default domain ?
by Marius Stan 15 Jun '04

15 Jun '04

Hello, I'm in the process of migrating from qpopper to dovecot and I've stumbled upon the least expected thing: In qpopper I can specify a 'default domain', which will be used if an user will only issue his username (not the whole email address) when logging in. Because of this, the users in my main domain don't use the whole email address when getting their mail. I'd hate to have to call each of them and guide through their OE menus to fix this issue, so I must ask: Is there any way at all of specifying a default domain in dovecot ? Thanks, Marius

[Dovecot] Wishlist item, POP3 welcome message
by Christian Balzer 15 Jun '04

15 Jun '04

Hello, With qpopper you get something like this after a successful login: --- +OK test has 6 visible messages (0 hidden) in 11822 octets. --- This gives a clueful user or support people a quick status about the size of this mailbox, very helpful in full quota scenarios. Would be nice if the next dovecot would have such a feature as well. I doubt the same is (easily) applicable for IMAP (though would be trivial once maildirsize is supported). Another thing would be PIPELINING for POP3, but I doubt it's all that helpful in this day and age of bountiful broadband.

[Dovecot] breakin' dovecot
by Tom Allison 14 Jun '04

14 Jun '04

I know this is cruel, but I figured out a way to break dovecot, temporarily. The really great news is that it recovers nicely. I'm also not sure if anything can be done about this, since I've seen the same thing happen with courier-imap, uw-imap, and maybe cyrus-imap. I used cyrus-imap for such a short period of time that I didn't get to really test it much. how to... (this was done on a fast ethernet network) get a folder with some 1,000+ unread/unseen emails. pop in with mozilla mail and wait for it to download all the mail information from ther server. press and hold the delete key. After about 300 emails being deleted, the imap server will appear to "freeze" and the "M" will keep cycling as if it's doing something. This will not recover until I move off the directory and return to it. hold delete key and repeat. If you do anything less than holding it down, it probably won't fail. It's a timing issue. I'm really not sure if it's even worth looking at. I'm not trying to identify this as a bug/defect/anything. But when I get a new piece of software I am really interested in what it does when it chokes. An old boss of mine would take my user applications and test them my rolling his hands across the keyboard for about a minute and if it hadn't crashed or entered bad data, it was a success. Please note that when I did this under courier-imap, it would stop refreshing itself from any/all directories until I logged out ( quit mozillia ) and logged back in again. So I would consider this to be a vast improvement in that regard. I should check what it logs when this happens, my guess is...nothing because it's frozen.

[Dovecot] Fedora dovecot Testing Needed
by Warren Togami 12 Jun '04

12 Jun '04

http://people.redhat.com/wtogami/temp/dovecot/ dovecot-0.99.10.5 binary packages for FC1 and FC2 are available here. I need feedback from Fedora users with THESE ACTUAL BINARIES before pushing them to official updates. Note: This does not solve the SSL related crash issue. That requires a patch to OpenSSL or kernel. I am still trying to convince the maintainers to patch it. Warren Togami wtogami(a)redhat.com
