[Dovecot] 1.0-test16 - nearing usable state
by Timo Sirainen 18 Jun '04

18 Jun '04

http://dovecot.org/test/ Here you go, maildir syncing problems finally fixed (I hope). Well, except there's this "new-dir-only syncing" optimization which I'm not really sure if it works as it should. The bug really was in index code as I was beginning to suspect. The good thing is that while trying to figure it out over the last several weeks I thought of many other potential problems (race conditions) which got fixed. Those would have been much harder to find than this one :) Finally I thought I'd stop looking at the code and just begin dumping tons of debugging data to see where exactly it goes wrong. After few hours of debugging I figured out it was because message was being removed from index but not from maildir. 5 hours of sleep later I woke up, thought a while, figured out where it must be, got up, half an hour more debugging and found it. :) Code merging two UID range buffers into one was buggy, inserting one line of code fixed it. So .. Maybe I'll finally start using this myself now. The next important problems seem to be some random error messages about index locking timeouts and some asserts in some situations.

Re: [Dovecot] IMAP and webmail applications
by durango99 18 Jun '04

i thought squirrelmail would be way too much of an overkill for my needs also but i went for it. i'm using debian and i got the squirrelmail package installed and working within 15 minutes. what really makes life easy is that squirrelmail comes with a configuration utility (squirrelmail-configure). it was very easy to get things configured without worry about a lot of conf files :) i also like the many plugins that people have created for squirrelmail. it's also very simple to add these plugins into squirrelmail using squirrelmail-configure. i had originally been ssh and mutt to check my mail, but i decided it be nice to have a web front-end and squirrelmail /apache /dovecot /procmail /spamassassin /gotmail /getmail /fetchyahoo have been a good mix for me. the hardest part for me was figuring out procmail and not squirrelmail :) my 2 cents, dan > I've been hunting around for a webmail application other than > squirrelmail for reasons that really don't matter. > > But I'm seeing that a lot of these applications tend to sometimes access servers via IMAP, but they always seem to have a touch more information needed than might be for an IMAP session. > > An example is openwebmail.

[Dovecot] shared authentication
by Kevin 16 Jun '04

16 Jun '04

whats the recommended way to share a user auth info between dovecot and postfix? sasldb seems like it could work but nobody really seems to like using the giant mass that is sasl. i also cant find any information on actually getting dovecot to use sasl past the configure options. i looked at timo's patch for postfix to use dovecot-auth but it doesnt apply correctly on the 2.1 branch. so what are people using to share passwords between the two without using the system passwd?

Hello, any plans to support this in the future?

[Dovecot] Return (revenge?) of the "pop-lock".
by Christian Balzer 16 Jun '04

16 Jun '04

Hello, The users here have been migrated to the new mail system with dovecot 0.99.10.5 (Debian package) on the backends. Storage is maildir, only pop3 access for now. I see very seldom occurrences (compared to the session wide pop lock of qpopper on the old system) like this: --- Jun 16 14:35:52 mb01 pop3(user(a)gol.com): Timeout while waiting for release of exclusive fcntl() lock for index file /mail/spool/mb01/9ef/f73/af.user/.INBOX/.imap.index --- These are people with slow connections and at least one large mail in the box, with their client aborting w/o terminating the session properly. I presume the timeout for this is hardcoded, as all the config parameters for timeouts are mbox related, rite?

[Dovecot] /var/mail dotlocking workaround
by Timo Sirainen 16 Jun '04

16 Jun '04

I added "mail_extra_groups" setting which can be used to give imap/pop3 process access to additional groups. So what this means is if you set it to "mail" you can finally remove o-w access from /var/mail directory. Leaving the sticky bit could still be a good idea, so there's no way users to be able to delete each others inboxes. Here's a patch against 0.99.10.5: http://dovecot.org/patches/mail-extra-groups.diff

[Dovecot] dovecot non-local users
by Tom Allison 16 Jun '04

16 Jun '04

From the docs: System without local users -------------------------- <snip> Having one uid per user would mean that in case of a security hole in Dovecot, the user still couldn't read other peoples mails. Use this if possible. ----- I don't quite understand this one. If you aren't a local user, what's the uid all about? Do I do something like: create a user for mydomain in /etc/passwd (eg: user:domain_dude, home:/var/dovecot) with a valid home/uid/gid. Plug in the uid/gid/home for domain_dude in the authentication and have a data structure of /var/dovecot/%d/%n/Maildir or %h/%d/%d/Maildir where %h = "/var/dovecot" via /etc/passwd. Something like that?

[Dovecot] review of my configuration
by Tom Allison 16 Jun '04

16 Jun '04

Over the last week I've set up dovecot and imap and imaps support. I've even tried to break it but it's been doing very well. Now I'm trying to set up a webmail interface. Rather than use the common squirrelmail, I thought I would try openwebmail. Mainly because it's written in perl, of which I am a big fan. However, I ran into some errors in openwebmail that actually may tie back to dovecot. Here's how: dovecot configuration userdb = /etc/passwd passdb = pgsql.... ---this allows me to use the $HOME, uid, gid from the passwd file and not have to carry two copies of it (/etc/passwd and pgsql) However, under openwebmail I don't seem to have this option as they are really determined to require a home, uid, gid for each user that logs in. As witnessed by the following line: Tue Jun 15 20:23:34 2004 - [31572] (unknown) tallison - userinfo error - auth_pgsql.pl, ret -3, Can't execute SQL statement: ERROR: column "uid" does not exist Sure looks familiar doesn't it? (see, it's relevant!) Since I was thinking that maybe it might be interesting to do some email set up to support multiple domains and users some day, and I want to try out the openwebmail sooner than that. I'm getting the impression that it might be easier if I just made the leap today and started to reconfigure everything for multiple domain hosting and all the cool stuff. Now, I can probably muddle through this without too much internal damage. But I keep getting stuck on one point. How can I filter the delivery of email like I do with procmail, when I am delivering mail to many users, none of whom have a /etc/passwd entry? Are there any alternative ideas on how to do this?

[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] Shared folders?

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.

[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.

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

[Dovecot] folders via softlink
by Chris Barnes 12 Jun '04

12 Jun '04

I have recently switched from the UW imap server to dovecot and things seem to be working nicely. One thing that I can't seem to figure out however, is how to get dovecot to show folders that are a softlink. We run SpamAssassin. Users can use both their own personal spam folder as well as a shared spam folder. For messages that everyone would consider spam, the user can simply drag the message to the shared spam folder (messages that are only "spam to them" would go into their own spam folder). sa-learn is then run nightly for each user against both the shared spam folder and their personal spam folder. The shared spam folder is simply a file that everyone has rwx access to and is softlinked to ~/mail/SharedSpam. This used to work fine with UW imap because it didn't seem to care that this was a softlink. However, apparently Dovecot DOES care because when the user resets their folder list and the user selects the folder and chooses "show", they get the error message: Could not show "SharedSpam". The server refused to show it. The folder might already be shown. I have tried editing the .subscriptions file by hand and it does cause the folder to show up, but when the user trys to use it, they get the same error. Is there a setting somewhere I'm missing? -- + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + Chris Barnes AOL IM: CNBarnes chris-barnes(a)tamu.edu Yahoo IM: chrisnbarnes Computer Systems Manager ph: 979-845-7801 Department of Physics fax: 979-845-2590 Texas A&M University

[Dovecot] some messages showing up twice
by alan premselaar 12 Jun '04

12 Jun '04

I've recently installed dovecot 0.99.10.5 on a redhat 7.3 machine. Everything seems to be running fine and smoothly for the most part, however in the past few days I've seen a couple of duplicate emails (and so have a few of my users) which don't appear to have been processed twice by sendmail. also, on one of my IMAP sub-folders my mail client (mozilla thunderbird version 0.6+ (20040610) nightly) reported 1 unread email, but it didn't show up in the list. it appears that the index for that subfolder got corrupted (i moved all the .index* files to a backup directory and when i checked that folder, it recreated the index files and then showed me the one unread email) I realize that i'm using a nightly build of a beta mail client, but some of my users reporting similar troubles are using Mail.app and other clients. does anybody have any suggestions as to what I might do to get some useful debug info and/or find the cause of this problem? thanks, alan

[Dovecot] 'append aborted'
by Tom Allison 12 Jun '04

12 Jun '04

I'm copying all my archives from one imap server on one machine to the imap-ssl dovecot server on another machine. After a bit, there's an error that's tossed up on my mozilla client that says the imap server couldn't complete the operation with the message append aborted. It keeps popping up after anything from 50 to 300 emails. Last night I was able to move ~12000 emails from one machine to the other without the ssl enabled. Any hints on what to look for?

How can I secure dovecot listening on port 143 to specific machines only? Squirrelmail suggests using non-ssl if the imap daemon is on the same host... Otherwise squirrelmail could use TLS but what about other clients wanting to use SSL on port 993? (sorry I don't know enough about TLS).

[Dovecot] auth failure
by Tom Allison 11 Jun '04

11 Jun '04

well, with some help I've made a fair amount of progress on my box. It's working out much easier than I had anticipated and perhaps my notes will be useful some day. I have two questions... Here is where I am: cling:~# egrep -v "^($|\#)" /etc/dovecot.conf protocols = imap imaps login = imap login_max_processes_count = 16 login = pop3 max_mail_processes = 512 verbose_proctitle = yes default_mail_env = maildir:~/Maildir mailbox_check_interval = 1 auth = default auth_mechanisms = plain auth_passdb = pgsql /etc/dovecot-pgsql.conf auth_user = root auth_verbose = yes cling:~# egrep -v "^($|\#)" /etc/dovecot-pgsql.conf connect = dbname=dbmail user=dbmail_reader password=SECRET default_pass_scheme = PLAIN-MD5 password_query = SELECT passwd AS password FROM users WHERE userid = '%u' I've created working passwords using 'mkpasswd --hash=md5' and plugged the results into my database. I can login and everything looks pretty cool. Except, as near as I can tell, I'm sending plaintext authentication over the wire. My best guess is that my password gets munged into digest-md5 format before it goes over the wire. At this point I'm of the opinion that I'm reasonably secure. True so far? My guess is that the next step in security is to go for imaps and ssl configuration. But my debian installation doesn't appear to have the dovecot-openssl.cnf file referenced in the configuration.txt file. Is this missing from dovecot or am I looking at a debian problem?

[Dovecot] Corrupted index file
by Niilo Kajander 11 Jun '04

11 Jun '04

Hi, I've been wondering for a while if reiserfs is dovecot+maildir safe or not. I get this too often (and my imap session gets disconnected): Jun 9 08:42:32 sun imap(nk): Corrupted index file /home/nk/Maildir/.INBOX/.imap .index: UIDVALIDITY changed in uidlist This happens always when a new mail arrives in maildir. It's a Fedora Core 2 box running dovecot-0.99.10.4-4 (redhat) package. Could the reason for these corruptions be something else than reiserfs? I know there has been some problems with Fedora+dovecot but I haven't seen this one reported here. TIA, -- Niilo Kajander <nk(a)kajander.fi>

[Dovecot] bleah
by Tom Allison 11 Jun '04

11 Jun '04

Not to be a bitch, but I've asked several times about some basic questions or examples to clarify the essentials for configuration. What do some of the parameters mean? Expecially the ones that are mentioned only one in a paragraph and no where else in the documentation or wiki. (ie: login_process_per_use) And there have been a few others as well. that I won't bother to repeat. But I've been sitting on this list for a while yet and have found that when it comes to configuration, none of the emails posted have been answered or addressed. The closest I got was a suggestion to use views instead of tables in postgres. But technically nothing was ever said about dovecot itself. So I have to ask. Is the sketchy documentation in the source file, the web page, wiki, and limited reponse on the mailing list a matter of "I haven't gotten around to it yet" or a deliberate move to promote the commercial support potential for Procontrol? I've run into this kind of environment twice before (cyrus and razor) and in the case of cyrus they just didn't believe in doing the documentation but suggested I write it myself. That may be the case there as well ("I haven't gotten around to it yet". That's OK but cyrus has the difficulty of no one still not providing any answers to how anything was done, configured, functioned, or why. So documentation was kind of a reverse-engineering project in itself. In the case of razor it's a mix of no time and they would rather support the company than the project. I went back and re-read the emails that I had posted earlier and am pretty sure that they weren't too stupid (ie: how do I test an imap connection), difficult, or obscure (well, maybe one). I'm just trying to find more information on how to correctly configure this server such that I can retain the concept of keeping security in mind. I'm trolling through the archives and there doesn't seem to be much discussion from anyone else. So maybe I'm really stupid and can't do authentication schemes. I'm sure by this point I've really pissed a few people off and for that I mostly apologize. I'm a little bent here myself. It just that I didn't plan on having to set up sniffit to track my IMAP traffic in order to verify that things were actually working securely. I'm going to plug along and do it myself and probably get something to work. I have plain_text authentication working now, but was really hoping to actually get something secure. At this point I really don't expect an answer, but do hope that after 1.0 is released there will be time available to get some documentation in order. IMHO the level of documentation that is available on a software project is critical to it's use.

[Dovecot] "virgin" mail accounts
by Christian Balzer 11 Jun '04

11 Jun '04

Hello, I'm willing to swear that with the 0.99.10.4 Debian package in my rather extensive tests with mailbox format dovecot created not only any missing parental directories but also the INBOX file, but the later I can't prove/test now as I upgraded all respective boxes. However 0.99.10.5 will still create (if needed and possible) missing directories for mbox storage, just not an empty INBOX. But with maildir, it will not even do that, from a test with pop3 and imap login attempts to a freshly created account that had not received any mails yet: --- Jun 10 12:58:03 mb01 pop3-login: Login: test [203.216.5.92] Jun 10 12:58:03 mb01 pop3: I/O leak: 0x8050ce0 (0) Jun 10 12:58:03 mb01 pop3: I/O leak: 0x8084aa0 (1) Jun 10 12:58:49 mb01 imap-login: Login: ttest [203.216.5.92] Jun 10 12:58:50 mb01 last message repeated 3 times Jun 10 12:58:50 mb01 dovecot: child 9193 (imap) killed with signal 11 --- It died not very graceful in either case, esp. the later. Unless there are very RFC'ish and imperative reasons, I'd suggest that dovecot creates all missing bits if possible no matter what the storage method or pretends to have encountered an empty mbox file or maildir cur/new respectively. The rationale should be obvious, no frantic user calls about "My mail is not working" when the answer is "Duh, that's because you never ever received one yet". ;) Regards, Christian Balzer -- Christian Balzer Network/Systems Engineer NOC chibi(a)gol.com Global OnLine Japan/Fusion Network Services http://www.gol.com/

[Dovecot] 2 problems
by Cor Bosman 10 Jun '04

10 Jun '04

Hi all, im testing dovecot as a replacement imap server and noticed 2 problems in 0.99.10.5. if you use dovecot/pop on an account who's quota is fully used, dovecot will ungracefully stop. This will only happen when the account is first accessed by dovecot (for instance, when offering IMAP to an existing userbase using dovecot, or when the index files have inadvertently been deleted). +OK dovecot ready. user scorpio +OK pass xxxxxxxx +OK Logged in. Connection closed by foreign host. The same goes for imap: * OK dovecot ready. . login "scorpio" "xxxxxxx" . OK Logged in. . select INBOX . NO Out of disk space This is a bit of a problem because one of the remedies of solving an out of disk space problem is deleting email, which you cant now. Cor

But then I can not create folder anymore from Mozzila, or view any thing other than inbox. I am still able to see message in inbox since I haven't change the location of inbox. Please help. Nina

[Dovecot] authentication configuration
by Tom Allison 10 Jun '04

10 Jun '04

I've included the non-defaulted bits of my dovecot.conf file at the bottom of this email. As I understand my set-up it's using unix authentication methods (/etc/passwd via pam?). Considering disable_plaintext_auth and auth_mechanisms, what exactly is being passed? I was hoping to get auth_mechanism = digest-md5 but that's not working out very well right now. It seems I can only do plaintext authentication. I got stuck on the userdb/auth_passdb settings. Can someone give me an example of how to configure for md5-digest authentication? My current guess is: disable_plaintext_auth = yes auth = digest-md5 auth_mechanism = digest_md5 auth_passdb = /etc/mydigestfile How would I set this for pgsql? auth_passdb = /etc/dovecot-pgsql.conf ### non-default config settings. protocols = imap imaps disable_plaintext_auth = yes login = imap login_max_processes_count = 16 login = pop3 max_mail_processes = 512 default_mail_env = maildir:~/Maildir mailbox_check_interval = 1 auth = default auth_mechanisms = plain auth_passdb = pam auth_user = root

[Dovecot] configuration
by Tom Allison 10 Jun '04

10 Jun '04

I've noticed that there are some parameters mentioned in the docs that aren't identified therein (ie: login_process_per_use). Is there a more generic set of docs that can identify what each of the parameters and what they do, or at least something that will allow me a simple how to to avoid embarrasing situations. I supposed I should only settle for ssl based connections (imaps/pops) but I will be open to digest-md5 if I could. I'm also curious to see how I can use pgsql authentication with dovecot. I think this would be great to work with since I'm basing all my postfix settings around postgresql as well. But for now I'm not sure how to use postfix authentication with the file directories I'll need to use for the maildirs (and procmail!).

If more than one # row is returned or there's missing fields, login will automatically fail. # I'm a bit slow here, so if someone could just nod if I'm in the right direction: I want to support IMAP for at least two domains. Therefore I have to use the authentication string of: SELECT password FROM users WHERE userid = '%u' and the user must enter their entire email address for their login name. (I can do this!) I want some portion of these domains and users to be consistent with existing accounts in my /etc/passwd database. I don't expect to use passwd information for the username and password, but I want the information returned for joe(a)domain2.com to be for the user:joe in my passwd file and have his email in /home/joe/Maildir. Similarly, I want others (either fred(a)domain2.com or jane(a)domain1.com) to be (ideally) all driven under a non-local account name and login. For this second one, I'm thinking I need to do something like this in the user information query (this is mostly a guess): for joe(a)domain2.com (/etc/passwd) :: jane(a)domain1.com (no passwd) home - /home/joe --or-- can I use ~/ :: /var/spool/imap/%d/%n ?? mail - maildir:~/Maildir :: maildir:/var/spool/imap/%d/%n ?? system_user - joe :: (a guess -- adduser dovecot-imap to passwd maybe) uid - joes uid (1002) :: dovecot-imap uid (510) gid - joes gid (1001) :: dovecot-imap gid (510) with seperate group This is where I get fuzzy. If someone could help me figure out where I went wrong I would appreciate it. If I did this correctly, then in theory I could pass email delivery to procmail and have one set of rules (/etc/procmail) do some additional filtering for all the email under my domain1.com (spam filtering mostly) and perform a final delivery to maildirs in /var/spool/imap/doamin1.com/jane/ Or am I sleep deprived?

[Dovecot] dovecot newbie question about "invalid key" problem
by Joakim Verona 10 Jun '04

10 Jun '04

Hello list, I've trying to migrate a small uw-imap server to dovecot. It works somewhat, and speed seems greatly improved, so thats great. However, I get an "invalid key/Internal Error" problem when connectiong to my INBOX with thunderbird. According to google this is a well known problem with mozilla mailers. Dovecot is not lenient with this bug in thunderbird. Is there some workaround for this? I noticed that its possible to turn on some client bug workarounds for outlook. Does the same go for mozilla? I tried one described remedy, which was to delete the account information and re-register the account. This didnt help. The problem seems to be only with INBOX, which I have mapped to /var/spool/mail/<username>, not my other imap mailboxes. Im running gnus as well and the problem doesnt seem to occur there. My configuration: Redhat 9 dovecot 0.99.10.5 (from DAG repository RPM:s) Another question: Would it be possible to run uw-imap on one port, and dovecot on another? Or would that corrupt the mailstores? Regards, /Joakim

[Dovecot] Feature request?
by Stephen K. Gielda 10 Jun '04

10 Jun '04

I'd like to toss a feature request on the table for consideration. We currently use a different popd because of a feature that allows us to restrict pop access based upon an allowed users list. This is the only thing that keeps us from using the popd in dovecot currently. It's a simple text file of usernames that are allowed to use pop, if the name isn't in that list then pop access is denied. Is this something that can be considered for a future feature addition? Would anyone else also find this useful? /steve

[Dovecot] Help: RH9 upgrade (mbox)
by Guy Davis 09 Jun '04

09 Jun '04

I just upgraded my RH9 server with UW-IMAP to Fedora Core 2 and after a short try with Cyrus, I'm hoping to get Dovecot configured. My problem is getting Dovecot to recognize my old mbox mail folders. It correctly shows the INBOX contents from the /var/spool/mail/davis mbox. However, I also had a bunch of mboxes such as: /home/davis/Mail/Sent /home/davis/Mail/Lists/list1 Reading the documentation, Dovecot indicates it will recognize mbox files within the ~/mail directory. So I moved my mail over giving: /home/davis/mail/Sent /home/davis/mail/Lists/list1 Unfortunately, after restarting Dovecot and restarting my IMAP client (Mozilla), I don't see anything other than my Inbox. If I create a file (/home/davis/mail/.subscriptions) with 'Sent' in it, and restart things then I can see Inbox and Sent. This would let me have a single directory with multiple mbox files in it. However, I'm not able to get Dovecot to recurse and let me see mboxes in subfolders such as: /home/davis/mail/Lists/list1 As well, when I first connect to Dovecot via Mozilla, I get an error saying: 'The current command did not succeed. The mail server replied "Invalid mask"'. What does this mean and how do I correct it? Any help would be greatly appreciated. Thanks, Guy

[Dovecot] Setting IMAP root as user's home directory. How?
by Silviu Marin-Caea 08 Jun '04

I'm trying to set up dovecot to use /home/username as IMAP root, but it keeps creating /home/username/mail. I need /home/username in order to migrate with the least changes from uw-imap, just by copying .mailboxlist without the INBOX line in it into .subscriptions I tried each of these, one at a time: default_mail_env = mbox:~/:INBOX=/var/mail/%u default_mail_env = mbox:%h/:INBOX=/var/mail/%u default_mail_env = mbox:/home/%u/:INBOX=/var/mail/%u In each case, dovecot was stubornly creating /home/username/mail Please CC me, I'm not on the mailing list.

[Dovecot] mta/mda config
by Jure Pecar 04 Jun '04

04 Jun '04

Hi all, I'm at the stage of planning our new mail system and am evaluating dovecot for it. For large mailstore setups, it makes sense to split maildirs across many directories. I see that setting default_mail_env to something like maildir:/var/imap/domain/%1d/%d/%1u/user/%u/ would create almost identical on-disk layout as multidomain cyrus setup. Now, as dovecot does not have its own mda or lmtp daemon, how does one configure mta (eg. postfix) to deliver mail in such maildirs? Related question ... any cyrus to dovecot migration tales? :) -- Jure Pečar

[Dovecot] Advice on converting from Mbox to Maildir?
by Villalovos, John L 04 Jun '04

04 Jun '04

Does anyone have advice or pointers on good documentation on how to convert a system from using the Mbox format to using Maildir? I recently upgraded to Fedora Core 2 from Fedora Core 1 and discovered that UW-IMAP was gone. So I switched over to using Dovecot. So far so good. But I would like to convert my system to start using the Maildir format. How easy is this to accomplish? Can I keep my Inbox /var/spool/mail/user_name as an mbox format and have my other folders as Maildir? What would I have to change for Sendmail to make it use Maildir for the Inbox? Can procmail support Maildir? Any pointers or help would be much appreciated? John

John Duino wrote: > That was the one question I haven't had answered (and it's > mostly just out of pure paranoia that I ask it :) Yes. POP email works fine with Maildir for me. I am using dovecot-0.99.10.5-1 which was on the development tree of Fedora. Though I would think the one that came stock with Fedora 2 should work as well. I have no reason to think it won't. One note. I don't use POP that much. I have one person who uses it and they haven't complained. > So if all the mail is moved to Maildir (thus eliminating the typical > mailspool), and somebody pop's onto the server, Dovecot will use the > Maildir/Inbox for the pop? Yes it will. If you read the mail-storages.txt documentation file it talks about it. I would read the section on "Detecting what to use". I did NOT set the default_mail_env variable in my /etc/dovecot.conf and it figured it out automagically :) Good luck, John

[Dovecot] 0.99.10.5 imap flag update issues

Hi, there is an issue left in 0.99.10.5 which (I think) is a problem with imap status flags. It shows up in two places: (1) When new mail is delivered to the inbox, the last read mail changes to "unread". (2) When you move mails from the inbox to another folder with Mozilla (1.6 on win32, Linux, NetBSD), they are not removed from the inbox, effectively performing a copy instead of a move. And, while I am at it, (3) I see a regular log entry from a MS Outlook 2000 SP 3 Jun 3 10:26:23 bounce imap-login: SSL_read() syscall failed: EOF [130.83.XXX.XXX] The setup here: OS NetBSD 2.0beta, MTA sendmail 8.12.11, LDA maildrop 1.3.9, dovecot 0.99.10.5, OpenSSL 0.9.7d Any ideas? hauke -- Hauke Fath /~\ The ASCII Ribbon Campaign Institut für Nachrichtentechnik \ / No HTML/RTF in email TU Darmstadt X No Word docs in email Ruf +49-6151-16-3281 / \ Respect for open standards

[Dovecot] Getting POP3 up and running

03 Jun '04

Hi! Now that I happily smiling have Squirrelmail working on the new setup (Fedora Core 2), the next hurdle seems to be getting POP3 to work. According to my understanding of the documentation I changed the protocols line in dovecot.conf to: #protocols = imap imaps pop3 pop3s then restarted dovecot, but still can't connect to pop3 (not even after rebooting the whole system). Doing an nmap on my server does not show port 110 as open. Any clues as to what I may be overlooking?

[Dovecot] Loggin error with Squirrelmail on Fedore Core 2
by Antonio Nunes 03 Jun '04

03 Jun '04

Hi! I am switching a mail server setup to a new machine which has RHL Fedore Core 2 installed, which uses Dovecot. I managed to get Squirrelmail to work on my personal account, but when logging in with some other accounts I get the following error as response: ERROR : Connection dropped by imap-server. Query: Capability I did a web search on this and found a message from Tim Middleton who experienced the same problem. He also suggests a workaround: "I put in a chron job to touch into existance any non-existing mailboxes for everyone in the passwd file periodically, which mostly eliminates the problem. But I'd still like to know why the server is having the problem, if anyone can make any suggestions." I would like to try this, but I am still fairly new to Unix. Could anyone show me how to set up such a chron job? Are there other, manual, ways to touch the mailboxes? Thanks, Antonio Nunes Don't let who you can be keep you from being who you already are.

[Dovecot] Supporting POP & IMAP with Sendmail
by John Duino 03 Jun '04

03 Jun '04

Greetings! I dug thru the archives but didn't see a clear answer to this. A client has an existing sendmail/pop3 system, and I would like to switch to dovecot for imap support. For imap I much prefer the Maildir format over mbox, however, sendmail natively dumps to mbox (mailspool) and that is what pop typically reads. I've read the threads on how to make sendmail write to Maildir. My problem is that I'd like to support both pop/mailspool and imap/maildir. While running dovecot in imap-only it will use mbox format to read the /var/mail/user as the Inbox and then create the full imap structure under ~user/mail but in mbox format, not maildir. If/when I turn on both pop and imap in dovecot will it allow this with the current config? Or will I still need to convert sendmail output to maildir...and then I assume dovecot/pop will read from ~user/Maildir/Inbox even though it is in Maildir format? Basically, if I'd prefer to not have to convert sendmail to Maildir format, have dovecot always treat /var/mail/user as the Inbox for both pop and imap, and for those who switch to imap, have it store their other folders in ~user/Maildir. Asking too much? Thanks! John

Timo says that it is NOT available in the version that comes with Fedora Core 2. It will be available in the 1.0 series by defining multiple namespaces. The current 1.0-tests allow this. > What would I have to change for Sendmail to make it use > Maildir for the Inbox? Sendmail does NOT need to be changed. > Can procmail support Maildir? Yes and that is what you need to change. I setup /etc/procmailrc to have the line: DEFAULT=$HOME/Maildir/ Make sure there is the terminating / on that line. What this will do is make all new mail that is delivered via procmail go to each user's Maildir folder. But what you need to do first is convert your existing mbox mail into maildir format. I used the program that was recommended to me: mb2md http://batleth.sapienti-sat.org/projects/mb2md/ This program worked great to convert my /var/spool/mail/user_name stuff and also folders that I had created under ~/mail/ So now my whole system is using Maildir format.

[Dovecot] dovecot and virtual hosting
by Vegard Svanberg 03 Jun '04

Hi. A usual hosting provider setup depends on having one IP ("virtual mailserver") per domain. Using dovecot on servers handling hundreds or thousands of domains today equals to having multiple instances of dovecot running. This problem could be solved by making dovecot take into account the IP address the user connects to and authenticate against the proper {database, table, pw-file, [...]} based on that.

[Dovecot] Serve list archives by dovecot IMAP
by Kenneth Porter 02 Jun '04

Has anyone considered setting up a Dovecot public server to serve the list archives by IMAP? Or does Dovecot not do anonymous read-only access? (I note by comparison that the Cyrusoft Mulberry list archives are served by an IMAP server. <http://www.cyrusoft.com/mulberry/support/anonimap.html>) It should be sufficient to set up Dovecot on some server in the dovecot.org domain and subscribe it to the lists.

[Dovecot] Dovecot + SSL + Fedora

I've been seeing the Dovecot/SSL/Fedora 1 problem. I have a dovecot server which tends to die at least once a day, with messages like these :- May 24 13:44:44 mail pop3-login: RAND_bytes() failed: error:24064064:random number generator:SSLEAY_RAND_BYTES:PRNG not seeded May 24 13:44:44 mail dovecot: Login process died too early - shutting down I noticed Timo's email about this at: http://www.dovecot.org/list/dovecot/2004-May/003316.html with the patch that just ignores the return code of RAND_bytes(). Would disabling SSL in dovecot.conf also be a reasonable way of avoiding the problem of dovecot crashing? My plan is to set ssl_disable = yes and also take out pops and imaps from protocols.

[Dovecot] 0.99.10.5 release candidate
by Timo Sirainen 02 Jun '04

02 Jun '04

http://dovecot.org/rc/ Thought I'd still make one 0.99.10.x release now that mbox corruption problems are (hopefully) fixed. Please test, if no problems are found this will be the final 0.99.10.5. Changes since .4: + MySQL authentication, patch by Matthew Reimer - mbox: APPEND reversed given \Draft and \Deleted flags - mbox: "LF not found" errors happened sometimes when X-IMAPbase header was updated. Possibly corrupted mbox sometimes. Thanks to Fabrice Bellet for finding this bug. - Custom flags couldn't be unset - Maildir: make sure ":2," is appended to filename when moving mails from new/ to cur/.

[Dovecot] Postfix SASL AUTH from Dovecot
by Timo Sirainen 02 Jun '04

02 Jun '04

Again today got annoyed at Cyrus SASL. Upgrading it to newer version had broken PAM support. Trying to login as "user@domain" resulted it only asking for "user" from PAM. Well, got it patched and working again, but I'd rather not go through it all the time.. So I finally did what I had been thinking about a year or so, change Postfix to use dovecot-auth directly. This required cleaning dovecot-auth quite a lot, but it seems to be working now. Actually I finally implemented support for initial SASL response as well. POP3's AUTH command had required support for it, strange that no-one ever complained about it not working. If you want to try it, you need very latest CVS version of Dovecot and this patch for Postfix: http://dovecot.org/patches/postfix-dovecot-auth.patch dovecot-auth can be run on it's own (configuration in environment variables), or you can use extra_sockets auth setting which is a ':' separated list of UNIX sockets where to listen in. You'd probably want to set it to /var/spool/postfix/etc/dovecot-auth, the location is hardcoded to /etc/dovecot-auth in the patch for now (smtpd is chrooted). The only real problem is that Dovecot creates the dovecot-auth socket using 0660 root:root modes, so you have to manually chmod it to 0666 or fix owner/group. I guess that needs some more thinking.. Probably each socket should have separate settings for it, but how to do it easily in configuration? .. The patch has also hardcoded dovecot path in Makefile.in, you'll need to change that.

[Dovecot] IMAP login name conversion
by Zoong Pham 01 Jun '04

01 Jun '04

Hi all, Out IMAP client (Outlook and others) use login name like joedirt(a)domainname.com I need dovecot to convert it to joedirt-domainname_com since that is the local login name. Can someone give me a hint how to do that? Is there any simple way to do it or do I have to modify any source code? Thanks, Zoong

[Dovecot] 1.0-test14: no sendfile() in Solaris 8
by Andreas Jaekel 01 Jun '04

01 Jun '04

Aloha. The current CVS snapshot and 1.0-test14 will not build on Solaris 8 because it does not provide a sendfile() funtion. It just has sendfilev(). Solaris 9 has sendfile(), though. Using the old sendfile-util.c from 1.0-test1 and setting HAVE_SOLARIS_SENDFILEV instead of HAVE_LINUX_SENDFILE in config.h works. Greetings, Andy.

[Dovecot] Small change to make dovecot pop3 uw-imap migration friendly
by Oleg I. Vdovikin 01 Jun '04

01 Jun '04

Hi, today I've finished migration from uw-imap daemons to shiny and fast dovecot. With thanks of dovecot my mail server load average drops by factor of ten even with ancient unix mailboxes. ;-) So, the only thing I've discovered is what POP3 uidls are different than ones used in the uw-imap. Luckily, the difference are only in the format string used in uidl response. So, I've made the following change in the code --- dovecot-0.99.10.4.orig/src/pop3/commands.c 2003-05-28 15:17:15.000000000 +0400 +++ dovecot-0.99.10.4/src/pop3/commands.c 2004-05-27 14:06:48.000000000 +0400 @@ -374,7 +374,7 @@ while ((mail = client->mailbox->fetch_next(ctx)) != NULL) { client_send_line(client, message == 0 ? - "%u %u.%u" : "+OK %u %u.%u", + "%u %08x%08x" : "+OK %u %08x%08x", mail->seq, client->uidvalidity, mail->uid); found = TRUE; } and got everything just like in the old uw-imap pop3. I'm current running RH9, but thinking of FC2 which uses dovecot. So, I've rebuild the FC2 rpm for RH9 including this patch. Pop3 users, which do not remove their mails from the server are really happy - they do not receive old mails twice. Probably this small change could be applied to the 1.0, or used as a config option. Any suggestions are greatly appriciated. Thanks, Oleg.

[Dovecot] 1.0-test14
by Timo Sirainen 31 May '04

31 May '04

http://dovecot.org/test/ Maildir syncing is still somewhat broken. I can't really figure out what the problem is. Maybe it's in indexes after all which are just causing bugs in syncing. I think I'll finish implementing mbox syncing and see if same problems appear with it. This release has mostly dovecot-auth changes: - Delay reporting failed authentications - Log IP address of failed authentications (if verbose = yes) - Password schemes can now be loaded from plugins. Example: http://dovecot.org/patches/1.0/password-scheme-lmpass.c - (now that I think of it, auth mechanisms could be implemented as plugins as well if they were placed in password-scheme directory, I think I'll change the directory name so it's more logical) - SASL initial responses are supported (POP3) - SHA/SHA1 password scheme implemented with OpenSSL - dovecot-auth can run as standalone process now (but that doesn't work with Dovecot itself at least yet) - Changes to make it more easier to use it outside Dovecot (eg. the Postfix patch) Added new variables which can be used: %l - local IP address %r - remote IP address %P - PID Added mail_log_prefix setting where variables can be used. So if you want eg. "imap(user,ip-addr,pid): ", set it to "%p(%u,%r,%P): ". And others: - added maildir_stat_dirs setting - several bugfixes for indexes

[Dovecot] Dovecot returns everything starting with "." as folder
by Christoph Hohmann 30 May '04

30 May '04

Hi, I'm using dovecot imapd 0.99.10.5 from debian unstable and I noticed that dovecot returns everything in the maildir folder that starts with a "." as a folder as the result of LIST "" "%" command without checking if it is really a maildir folder (must contain the directories cur, new, tmp and the file maildirfolder). This is a little bit annoying because it also returns Sylpheed's cache files '.sylpheed_cache' and '.sylpheed_mark' if they exist in the maildir. -- http://reboot.animeirc.de http://sylpheed-claws.sourceforge.net/

[Dovecot] dovecot API / Virtual Folders?
by James Moser 30 May '04

30 May '04

I was wondering if anyone has done something like this, or knows of any reason it would not work. Would it be possible to use dovecot's API to create virtual folders where when messages are placed in them some other application can be executed on them? With programs like DSPAM and SpamAssassin, and with users who do not have shell access to the machines, it would be nice if there was a way they could do something like this to use dspam/sa-learn, that way they could use it with any mail application. I don't like the idea of using cron to do this. -- James L Moser james(a)powweb.com PowWeb Hosting http://www.powweb.com /(bb|[^b]{2})/, that is the Question. mysql>SELECT * FROM user WHERE clue > 0; Empty set (0.03 sec) Health is merely the slowest possible rate at which one can die...

[Dovecot] dovecot and nfs
by Dan Stromberg 30 May '04

30 May '04

I configured dovecot on a Fedora Core 2 system - the version that comes with FC2. I was using it with a RHEL 3 NFS server. Dovecot would again and again get stuck trying to grab an fcntl lock, even though I specified that it should only use dotlocks in dovecot.conf. Sometimes it would segfault (leaving things locked?). Often there would be two dovecot imapd processes for the same user. I've since moved dovecot onto our internal NFS server, but we have many (relatively) external imap servers where it might be nice to use dovecot, and in a number of those scenarios, NFS would be a requirement. Thanks. -- Dan Stromberg DCS/NACS/UCI <strombrg(a)dcs.nac.uci.edu>

[Dovecot] Messages does not appear in OE6
by Mauricio Araya V. 29 May '04

29 May '04

Hi List! I have an issue with dovecot: Outlook express users sometimes can't see some emails (they are not even listed) that can be seen with other IMAP clients, I tested it (and it works) with Evolution, Outlook and SquirrelMail (a web mail). Please note that this is not the client bug reported at http://dovecot.org/clients.html with the message: "Message is no longer available on this server" I have the following configuration: - Postfix as MTA (ver. 2.1), using the Maildir format to store messages. - Dovecot 0.99.10.4_2 serving POP3 and IMAP. Relevant dovecot config: client_workarounds = oe6-fetch-no-newmail outlook-idle default_mail_env = maildir:/%h/Maildir Something important is that I am using freebsd 4.9, and dovecot is installed from ports (/usr/ports/mail/dovecot) Does anyone has the solution for this problem, or at least an idea of what causes it? Regards, -Mauricio

[Dovecot] IMAP views - and things to make Outlook Express not suck so much
by Geo Carncross 28 May '04

28 May '04

Some of the things that keep being brought up SEEM TO ME to be a form of IMAP crack that can be accomplished in a much more generalized manner with a little bit of thought. An idea I had a while back was for IMAP views. It accomplishes the four things I keep seeing on this list without being specific to any of them. Consider new configuration variables: rewrite Junk { folder = INBOX search = KEYWORD "Junk" post = +FLAGS (Junk) } rewrite Trash { folder = * search = DELETED fetch = -FLAGS (\Deleted) post = +FLAGS (\Deleted) } Views would not be deletable (unless one wants to invent some nonstandard IMAP extensions today), but they would otherwise look like regular folders. One could post and search and fetch messages as normal (with some alterations to various IMAP fields). In the examples I gave: A001 SELECT Junk A002 SEARCH ALL A003 SELECT Trash A004 SEARCH ALL A005 FETCH 1 FLAGS would be translated into: A001 SELECT INBOX A002 SEARCH ALL KEYWORD Junk A003 SELECT {for each SUBSCRIBED folder} A004 SEARCH ALL DELETED A005 FETCH 1 FLAGS Except, A005 would actually yield: * 1 FETCH (FLAGS ()) Instead of: * 1 FETCH (FLAGS (\Deleted)) It would probably be ideal if these were configurable per-user, but I'd be happy with system-wide rewriting. Options for rewrite could include: folder = folders that could be selected using LSUB OR a valid (existing) folder name. If this is system wide, pretty much only INBOX, INBOX.% and INBOX.* and * and % are valid :) search = tags to append to SEARCH operations on the view fetch = IMAP fields that are acceptable to STORE that we will pretend occurred when fetching. recent = IMAP fields that should be STORE'd when the \Recent flag is still set. post = IMAP fields that are acceptable to STORE that we will perform when APPENDing or STOREing. append = argument to be passed to /bin/sh -c which will receive on standard input the APPENDed body, and produce on output a STOREed body. open = argument for /bin/sh -c for when this view is SELECTed or EXAMINEd close = argument to be passed to /bin/sh -c for when the view is closed. index = argument to be passed to /bin/sh -c for when dovecot wants to index a portion of the message. standard input of the argument is the message, whereas standard output is the portion to actually index. path = a regular dovecot mailbox path that would contain the real contents of this folder. ro path = like path, but would be decidedly read-only (except for any side-effects generated by append =) Subprocesses that exit 99 would handle the task internally- thus any normal actions (such as for index = and append =) would not occur. Exit code 0 is for normal completion, and all other exit codes should generate an error. If one allowed open = and close = to be used on REAL folders, this would allow people to actually have the behavior UW-IMAP does by MOVING mail from /v/s/m into ~/mbox... One could use append = with a "Outbox" view that could write the queue at the same time as storing a copy into Sent Items. One could also use append for gpg-signing messages as they're being recorded. One could also use append for publishing to a mailing list. One could use index = to spell-check messages beforehand thus improving my chances of actually finding messages from my PHB. One could also use append =, recent = and ro path = to emulate shared folders support in a manner that would be useful for using IMAP folders as a kind of work-queue. Thoughts?

[Dovecot] dovecot immediately exits on Fedora 2
by Per Bothner 26 May '04

26 May '04

I "upgraded" my server running UW-IMAP on Fedora 1, to Fedora 2, which defaults to Dovecot. Unfortunately, the server refuses connecions from my client (Mozilla). It seems that Dovecot immediately exits: ps aux|grep dovecot shows nothing. Also, if I manually start up dovecot, it immediately exits, with no messages. (It does at least parse the config file, since tweaking that gives me errors.) What is surprising is that I haven't been able to "Google" to find anone else reporting someting similar, so I'm wonderring what makes my system unique. I tried downloading, compiling and running the current UW-imap. Mozilla is able to connect to it, and ask for a password, but rejects the login. Curious that we're getting two such very different failure modes. Help would be most appreciated; for now neither I nor others who use my imap server can access our mail (except by directly viewing the /var/spool/mail file). -- --Per Bothner per(a)bothner.com http://per.bothner.com/

[Dovecot] feature request: undeletable folders
by Marten Lehmann 26 May '04

26 May '04

Hello, as we all know from the big webmail-services like hotmail.com, yahoo.com, web.de and so on, several folders exist and nobody can remove them for a good reason, because some services rely on them: Trash, Junk, Sent. Can can't remove Trash, because every deleted message is just moved here. You can't remove Junk, because all messages recognized as spam is moved here. And you can't remove Sent, because all messages you sent through the webmail are saved here. With the common courier-imap, everyone either has to bloat his webmail client with permanent checking if the required folders exist and recreate them if needed, or he has to patch courier-imap each time a new release appears to extend to this certain functionality. So why not just include this feature in courier-imap generally? I think there's no need to handle these folders on a per mailbox basis. Courier-imap could look at a file that contains the unremovable folders (one per line) and deny deletion of this folders. Now you might say: "You could prevent deletion of this folders in your webmail client as well." But that's only the half of the truth, because if you just want to see webmail as one option of accessing the emails, but POP3 and IMAP access is offered as well, then deletion must be restricted at IMAP side. I didn't implement this feature yet, but I'll need it in near future, so either someone else implements it our I would send you a patch after I implemented it. Regards Marten Lehmann
