[Dovecot] flat file mailbox formats
by Timo Sirainen 15 Jun '04

15 Jun '04

I've tried to write the new mbox code in a way that it could be moved into generic flat-file library with mbox-specific code being implemented on top of that. The code would be useful for all formats that require modifying message headers to store the metadata. How many such are there? I suppose all such formats could be implemented by separating mails into 3 logical parts: - header ("From ...\n") - mail data (headers and body) - footer ("\n") Except keeping a separate header and footer is kind of annoying, my current code uses: - mail separator ("\nFrom ...\n") - first message header's skip counter: how many characters to remove from mail separator for the first message (1, for \n before the "From ..") - last message's footer Somewhat uglier, but I think all needed formats could be implemented with it? It's also simper and more efficient to implement.. Besides mbox, I know at least two variations which are used: AAAA-box: - I remember seeing this somewhere years ago, but I'm not sure if it's still used or if it has a real name.. - separator is four ^A characters (ascii 1) and LF - header skip counter is 5 - last message footer would be the same ^A^A^A^A\n dotbox: - mails are stored in SMTP format, ie. lines beginning with '.' are prefixed with another '.'. the '.' prefixes will have to be removed for IMAP, so this isn't as simple as others to implement. - separator is ".\n" - header skip counter is 2 - last message footer is ".\n" Any thoughts?

[Dovecot] dovecot + Fedora core 1
by Pablo Endres 15 Jun '04

15 Jun '04

Hi, I've installed dovecot-0.99.10.5 using the rpm from Dag Wieers, but when I start it all I get is nothing (but none of the processes are running). I checked the config file and set it up (I'm trying to use it with mysql support, but it doesn't work with traditional config) Any ideas -- Pablo Endres <epablo(a)comvoz.com> ComVoz Communications USA: +1 954 343-2085 Ext 199 Venezuela: +58 212 7713195 Ext 199 Colombia: +57 1 3256840 Ext 199

[Dovecot] Shared folders?
by Villalovos, John L 15 Jun '04

15 Jun '04

I haven't seen any info on this so I thought I'd ask. Is there support for shared IMAP folders? Quite a few people at work subscribe to the Linux Kernel Mailing List. I thought it would make more sense if there could be a shared LKML folder that they all could use. This would save disk space. Is this posssible? If so how? I am also looking into the idea of doing a local newsgroup of the mailing list but I don't have a news server software setup at the moment. John

[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.
