[Dovecot] Dovecot 1.0 beta3 and SUBSCRIBE
by Bertrand Leboeuf 21 Mar '06

21 Mar '06

Using: default_mail_env = mbox:~/mail:INBOX=/var/mail/%u:INDEX=/var/indexes/%u I have a ~/mail/.subscriptions file (copied from .mailboxlist) Using: telnet localhost 143 a04 LSUB "" "*" => works fine, gives the list of subscribed folders a05 LIST "" * => works fine, gives the list of all folders a06 SUBSCRIBE "test" => deletes the ~/mail/.subscriptions file, it never gets recreated and LSUB gives an empty list after that. Any clues Bertrand Leboeuf

I migrated from UW IMAP, copied ~/.mailboxlist to ~/mail/.subscritions When I access SquirrelMail, is sees the folders on the left side. If I modifiy my folder subscription, they dissappear all but INBOX, and the .subscriptions file gets deleted. What am I missing. Thanks Bertrand Leboeuf

[Dovecot] compilation and installation of dspam-plugin
by Stefan Schmidt 21 Mar '06

21 Mar '06

hello johannes, i just discovered your wonderful plugin for dovecot. it was pretty much exactly what i was looking for, only that i didn't know that yet :) "Instead of moving mail into special folders, the user has two actions available: moving it out of the SPAM folder and moving it into the SPAM folder. The dovecot plugin watches these actions [...] and tells dspam that it made an error and needs to re-classify the message, depending on the action the user took. The user can now move the message directly into whatever folder she choses, and it all works. [...]" i think this is the most usable and intuitive approach to dspam-training i have seen so far and would love to integrate dspam with this plugin into my current setup (postfix + maildrop + dovecot). i have installed dovecot via package from the debian stable section [1] therefore i am currently using version 0.99.14 in my setup. despite this difference in version i gave your betacode [2] a try together with the source of the corresponding dovecot-version [3], hoping it wouldn't crash and burn when used with my earlier version of dovecot. but i didn't get to the point where i could actually testdrive it. i tried compiling the plugin with the instructions contained in the file, but the compilation didn't suceed. ---------------------------------------------------------------------- stefan@myserver:~/sources/dovecot-dspam-plugin/dovecot-1.0.beta3/plugin$ gcc -fPIC -shared -Wall -I../src/ -I../src/lib -I.. -I../src/lib-storage -I../src/lib-mail -I../src/lib-imap -I../src/imap/ -DHAVE_CONFIG_H spam_plugin.c -o spam_plugin.so In file included from ../src/imap/common.h:4, from spam_plugin.c:32: ../src/lib/lib.h:6:22: config.h: No such file or directory In file included from ../src/lib/lib.h:23, from ../src/imap/common.h:4, from spam_plugin.c:32: ../src/lib/compat.h:31:4: #error uoff_t size not set In file included from /usr/include/sys/socket.h:35, from ../src/lib/compat.h:80, from ../src/lib/lib.h:23, from ../src/imap/common.h:4, from spam_plugin.c:32: /usr/include/bits/socket.h:36: error: conflicting types for `socklen_t' ../src/lib/compat.h:51: error: previous declaration of `socklen_t' In file included from /usr/include/netinet/in.h:23, from ../src/lib/compat.h:81, from ../src/lib/lib.h:23, from ../src/imap/common.h:4, from spam_plugin.c:32: /usr/include/stdint.h:111: error: conflicting types for `uint_fast32_t' ../src/lib/compat.h:46: error: previous declaration of `uint_fast32_t' /usr/include/stdint.h:141: error: conflicting types for `uintmax_t' ../src/lib/compat.h:38: error: previous declaration of `uintmax_t' In file included from ../src/lib/lib.h:23, from ../src/imap/common.h:4, from spam_plugin.c:32: ../src/lib/compat.h:107: error: redefinition of `struct iovec' In file included from ../src/imap/commands.h:6, from ../src/imap/client.h:4, from ../src/imap/common.h:5, from spam_plugin.c:32: ../src/lib-storage/mail-storage.h:435: error: syntax error before "mail_get_virtual_size" ../src/lib-storage/mail-storage.h:435: warning: type defaults to `int' in declaration of `mail_get_virtual_size' ../src/lib-storage/mail-storage.h:435: warning: data definition has no type or storage class ../src/lib-storage/mail-storage.h:438: error: syntax error before "mail_get_physical_size" ../src/lib-storage/mail-storage.h:438: warning: type defaults to `int' in declaration of `mail_get_physical_size' ../src/lib-storage/mail-storage.h:438: warning: data definition has no type or storage class In file included from ../src/imap/commands.h:7, from ../src/imap/client.h:4, from ../src/imap/common.h:5, from spam_plugin.c:32: ../src/lib-imap/imap-parser.h:45: error: syntax error before "uoff_t" ../src/lib-imap/imap-parser.h:45: warning: no semicolon at end of struct or union ../src/lib-imap/imap-parser.h:45: warning: no semicolon at end of struct or union ../src/lib-imap/imap-parser.h:47: error: syntax error before '}' token ../src/lib-imap/imap-parser.h:47: warning: type defaults to `int' in declaration of `_data' ../src/lib-imap/imap-parser.h:47: warning: data definition has no type or storage class ../src/lib-imap/imap-parser.h:48: error: syntax error before '}' token ../src/lib-imap/imap-parser.h:72: error: field `args' has incomplete type ../src/lib-imap/imap-parser.h:125: error: syntax error before "_imap_arg_literal_size_error" ../src/lib-imap/imap-parser.h:125: warning: type defaults to `int' in declaration of `_imap_arg_literal_size_error' ../src/lib-imap/imap-parser.h:125: warning: data definition has no type or storage class ---------------------------------------------------------------------- just in case it matters: i currently have gcc 3.3.5 installed. greetings, stefan [1] http://packages.debian.org/stable/mail/dovecot-common [2] http://snipurl.com/nvol [3] http://www.dovecot.org/releases/dovecot-1.0.beta3.tar.gz

[Dovecot] [patch] support tpop3d-style UIDLs
by Ben Winslow 20 Mar '06

20 Mar '06

Hello, I've attached a patch that adds an additional expando to pop3_uidl_format. The additional expando (%M) expands to the md5sum of the filename (which is already available via %f.) This UIDL style is compatible with tpop3d when using Maildir. The patch is against dovecot 1.0 beta3, and I'd love to see it be merged into the official tree. Comments welcome. -- Ben Winslow <rain(a)bluecherry.net>

But the plugin also looks at headers etc. which would be very hard to capture in a config file. Well, not impossible, but cumbersome. I'm not sure what you're after but say you want to be able to define folder actions in a config file. Let me draw up a hypothetical config file example with the logic of the dspam plugin. The syntax is sort of borrowed from Exim :) ----begin folder action config---- copy into "SPAM" fail condition !${defined:header:X-DSpam-Signature} fail message "Message doesn't have dspam signature!" run "dspam --signature ${header:X-DSpam-Signature} --is-spam" copy outof "SPAM" ignore to "Trash" fail condition !${defined:header:X-DSpam-Signature} fail message "Message doesn't have dspam signature!" run "dspam --signature ${header:X-DSpam-Signature} --not-spam" ----end folder action config---- I'm sure others can come up with examples where the config file has to be even more elaborate... I can imagine having a 'pipe' action instead of 'run' that would give the command the message on stdin for example. johannes

[Dovecot] VERY cool add-on request.
by Adam M. Dunn 20 Mar '06

20 Mar '06

I would like to have the ability to execute a command on a folder based on a user doing something like copying a message to that folder. This could be accomplished with a config file directive. For example, this would be EXTREMEMLY useful as a spam learning hook. Take a scenario where each user has their own spamassassin bayes database, and you want to give the users the ability to train their own database based on what they think is SPAM. It would be nice to give all the users a folder called Spam, and tell them to just copy/move mail into that folder, and spamassassin will automatically learn about it. If we had a configuration hook where you could execute on a copy/move, then I could tell Dovecot whenever a user puts a message into the Spam folder, execute 'sa-learn --spam --file %s' on that message. Sure we could just do an external script in a cron job to do it every hour or something, which I'll probably do in the mean time, but often users will just delete messsages after they copy into it. Doing it through IMAP means spamassassin will learn about it immediately. How cool would that be? It seems like an easy hook to implement. I would like to patch it myself for my own use, but I'm not very proficient in C. I saw someone on the net patched Courier to do the same thing so I know I'm not alone in wanting this. Anyone know how I could patch it? Can we add that to the feature request list? ~Adam

[Dovecot] mbox to maildir conversion

Give me more hints and I will add a new wiki page. The feedback the command gives is $ ./convert-tool Fatal: Usage: <username> <home dir> <source mail env> <dest mail env> Why does the tool want a home directory? What does it look for there? I know you say the syntax is the same for other tools but I don't know it for them yet either. :-) Guessing at the syntax for the source, it looks like the first thing is the format of the source (mbox:) followed by a directory containing mbox format files. The INBOX portion specifies the location of the mbox that the MDA puts incoming messages into. I can see the variables defined in doc/variables.txt, got that already. Is it intended to run both directions? That is, if I swap the last two args is will it convert maildirs into mboxes? This comment from Stian seemed pertinent as well. > But there is at least one "bug" with this; you should convert .'s in > mbox names to underscore or something, else it looks weird. Other than > that, it seems to work fine :) ..but I am unsure what 'looks weird' means. Can you give an example? Why is this tool under 'plugins' when it appears to be a separate utility? My guess is that it was easier to put there due to the build environment. Maybe it should install to a bin or sbin location? Thanks for all you do, Brian

[Dovecot] PAM authentification problem
by Vladislav Kyjasko 17 Mar '06

17 Mar '06

Hi everybody, we try to migrate our IMAP service from uw-imap to dovecot because of horrible server slowdown when a lot of people poking in theirs huge imap folders. So, I try to run testing instance of dovecot on different imap port (12143) I have trouble with authentication by PAM module of MIT Kerberos. It successfuly works for authentificate users of wu-imap but not for dovecot. I see in dovecot.log messages like that : Info: Dovecot v1.0.beta3 starting up Info: auth(default): client in: AUTH 1 PLAIN service=IMAP lip=10.0.0.154 rip=10.0.0.148 Info: auth(default): client out: CONT 1 Info: auth(default): client in: CONT 1 AGtDNLamUjvADNLamUjQRsbw== Error: auth(default): pam(kyyashko,10.0.0.148): Child process died Info: auth(default): shadow(kyyashko,10.0.0.148): invalid password field Error: auth(default): PAM: Child 6748 died with signal 11 Info: auth(default): client out: FAIL 1 user=kyyashko temp Almost all users are in kerberos DB and has in local shadow field "*KRB*" instead of encrypted password. So, line "shadow ... invalid password field" is OK (when I made a local password in shadow the login was success) My dovecot.conf looks like: sl_disable = yes protocol imap { listen = *:12143 } auth_default_realm = FZU.CZ auth_verbose = yes auth_debug = yes auth_debug_passwords = yes auth default { mechanisms = plain passdb pam { } userdb passwd { } user = root } original /etc/pam.d/dovecot I introdused by lines auth sufficient pam_krb5.so auth required pam_unix2.so use_first_pass nullok or tryed to substitute whole file pam.d/dovecot by actualy working one of imap: #%PAM-1.0 auth sufficient pam_krb5.so auth required pam_unix2.so use_first_pass nullok auth required pam_unix2.so account required pam_unix2.so but similary fruitless. Which direction I have to dig? P.S. Dovecot was built from dovecot-1.0.beta3-6.src.rpm on SuSE 9.0 with the same result like from dovecot-1.0.beta3.tar.bz2 :(

[Dovecot] Install/configure on FC4 with maildir and mysql
by Netlink Tech 17 Mar '06

17 Mar '06

Hello, I have a FC4 x64 server that I am configuring/testing. It had dovecot 0.99 loaded after I did a yum update. That worked great with mbox, the passwd file, and test users in /home/users/username. I would like to be able to authenticate virtual users by 'username(a)domain.com' and have them be able to use squirrelmail or Outlook/Outlook Express to access their email. Users have no reason to have a login (shell) account on this machine. I also would like to use the maildir format for performance. I also have hundreds of users currently on a RH9 mail server using qpopper in mbox format, hashed mail spool. Questions: 1)Is a mysql database the best way to support "user(a)domain.com" email users? (they don't have any reason for a shell account on this machine) 2)What version of dovecot should I be using? I prefer RPMs and at http://www.dovecot.org/list/dovecot/2006-February/011467.html I found http://fedora.ivazquez.net/yum/4/x86_64/RPMS.alternatives/dovecot-1.0-0.iva… I installed this and then configured procmail for maildir delivery. I configured dovecot-sql.conf for mysql driver...but the mysql driver does not appear to be compiled in this rpm. 3)Anyone have any general tips on how to configure such a beast? Thanks, Curt

It's my server and it's still running and working properly. Dovecot version is (as on the newer server) beta3, but the first Dovecot running was beta2 I think. Imap works properly on that server. Anyway Dovecot shouldn't crash ever if the index files are broken!

[Dovecot] Shared Folders Problem. Bug?
by Adam M. Dunn 16 Mar '06

16 Mar '06

I'm trying to get shared folders to work, and I've noticed a few issues. I created a private and public namespace, the private one with autodetection for Maildir or Mbox, and the public one for a public folder. Something like this: namespace private { separator = / inbox = yes prefix = location = } namespace public { separator = / prefix = Public/ location = maildir:/var/mail/public } My plan is to eventually setup a public area for users to drop Spam and Ham into for my spam bayesan filter. The problem is the Wiki says if you drop a file in the public area called 'dovecot-shared' with the same permissions and ownership, that any new files dovecot creates there will use those same attributes. This does not seem to be the case. I created a Maildir folder identical to the one on the Wiki, named everything 'dovecot:dovecot' since my dovecot server will be running as that user, as well as the 'dovecot-shared' file. I get permission denied errors in syslog when I try to access it via an IMAP client. The only way I can make it work is ignore the dovecot-share file and put all users in a common unix group and make the Public folder group 'rwx'. Also, I would like to be able to make the Public folder writable, but not readable. It seems if I take the read bit away, my IMAP clients complain. Does anyone know how to make that work? One thing about the namespaces while I'm at it. I had to put my private namespace first followed by the public one. If I reversed them, all the subfolders except the inbox in my mail directories disappear from the client. Is that a bug too? Thanks, Adam

[Dovecot] Problems with Oulook Clients
by Patrick Carney 16 Mar '06

16 Mar '06

Hello all. I have problems with clients running Outlook 2003 that keep getting IMAP server timeout errors, "mailbox in an inconsistant state" Are there any mods to be made to the config file that could eliminate this? It happens about ever 10minutes. Here is what our previous Sys Admin sent me on our setup. dovecot is the IMAP server that allows clients to connect and get to their mailboxes. Postfix is that part of the mail system that moves messages around, from one server to another and puts them in the appropriate mailboxes. Thanks Patrick

[Dovecot] migrating POP3 from UW IMAP: X-UIDL and X-UID
by Bertrand Leboeuf 15 Mar '06

15 Mar '06

With a INBOX mbox created by UW IMAP the messages in INBOX mbox contains the X-UIDL field When I use Dovecot POP3 with pop3_uidl_format = %08Xv%08Xu on the first run, X-UID is inserted, but all messages are downloaded again. What am I missing, I don't want the clients to download the read messages again. Thanks Bertrand Leboeuf leboeuf(a)emt.inrs.ca

[Dovecot] Imap crashes when trying to move messages
by ambroz.bizjak＠guest.arnes.si 15 Mar '06

15 Mar '06

The imap process crashes when SquirrelMail wants to move a message to another folder. I have run imap in gdb and talked to it the same way SquirrelMail does and got a backtrace. I am using Dovecot beta3. I am using it in combination with XMail, which has maildir databases. My system is Gentoo Linux on x86. The same version of Dovecot works great for me on amd64 with exactly the same config.

[Dovecot] Strange dovecot-uidlist behavior on maildir conversion
by allen petersen 15 Mar '06

15 Mar '06

Hi. So I just moved my email over from mbox to maildir. For the most part the conversion went fine, but I had a bit of an odd thing happen when I accessed my mail through dovecot. It seems that when I ran mb2md to convert my mailboxes from mbox to maildir, I got a lot of messages created that look like 1142356176.000000.mbox:2,RS 1142356176.000421.mbox:2,S 1142356176.000001.mbox:2,S 1142356176.000422.mbox:2,RS 1142356176.000002.mbox:2,RS 1142356176.000423.mbox:2,S 1142356176.000003.mbox:2,RS 1142356176.000424.mbox:2,S and so forth. Now, that really should be fine, that I can tell; each message has the same timestamp and a different, sequential delivery identifier. However, for some reason when dovecot accessed this directory, it created UIDs for these messages like so: (from dovecot-uidlist) 1 1142362834 915 1 1142356176.000488.mbox 2 1142356176.000207.mbox 3 1142356176.000425.mbox 4 1142356176.000117.mbox 5 1142356176.000398.mbox 6 1142356176.000335.mbox I have no idea where this order came from, but it's clearly not the order that I would have expected. I would expect that dovecot would sort these messages by timestamp, followed by delivery identifier. Instead, it put them in a seemingly random order. And, of course, my email client by default shows messages in the order that it gets them from the server, so now when I look at my email all of my old messages are shuffled until I do an explicit sort by date. Any idea why this is happening? Is there some reasoning behind this, or is it just a bug? I looked through the archives a bit, but didn't find a mention of anyone else with this particular problem. I suppose I could just create the initial uid lists by hand and put them in the correct order, but that really doesn't seem like the correct solution. Or I could actually dig through the source and find out exactly what it's doing, but, well, I figure that asking the list first is easier. For reference, I'm running dovecot 0.99.14-1 on debian sarge. I though that I was doing a good job by reproducing this on the newer version my ubuntu desktop, but it turns out that it's running the same version. :) -allen

[Dovecot] Rootless configuration
by James Davis 14 Mar '06

14 Mar '06

I'm trying to setup a rootless configuration so I can better manage the e-mail that comes to the mailbox of a unix account I have. I've successfully compiled Dovecot and followed the instructions for a rootless configuration, tweaking my config until Dovecot returns no errors. However I've got to a stage where upon running ~/..../sbin/dovecot it just quits with no server running and no errors. Any ideas? My rather small and basic configuration file is as follows... # Base directory where to store runtime data. base_dir = /home/jamesd/imap/dovecot/run/ # Protocols we want to be serving: protocols = imap listen = * ssl_disable = yes log_path = /home/jamesd/imap/dovecot/logs/ info_log_path = /home/jamesd/imap/dovecot/logs/ ## Login processes login_dir = /home/jamesd/imap/dovecot/run/login login_chroot = no login_user = jamesd ## IMAP specific settings protocol imap { listen = *:10143 } ## Authentication processes auth default { mechanisms = plain passdb passwd-file { args = /home/jamesd/imap/dovecot/etc/passwd } user = jamesd } Many thanks, James -- http://www.freecharity.org.uk/ - Free hosting for charities http://jamesd.ukgeeks.co.uk/

[Dovecot] Shared maildir through namespace help...
by Brice Figureau 14 Mar '06

14 Mar '06

Hi, I'm a happy user of dovecot since the 0.99.x days, and recently switched my user base to 1.0b2. Now, to the point, I got a request (from marketing) to share a lot of maildirs between two (and possibly more) accounts. Those two accounts have differents uid/gid. The maildirs are actually in one of the account. I thought I could possibly craft a public namespace for those maildirs as explained in the wiki, but alas, it doesn't quite work as I expected: excerpt of dovecot.conf: namespace public { separator = / prefix = marketing/ location = maildir:/home/marketing/Maildir:INDEX=%h/ } users belong to the marketing group. $ find /home/marketing/Maildir -ls 4767751 4 drwxrwxr-x 3 marketing marketing 4096 Mar 14 11:57 . 4767752 4 drwxrwsr-x 6 marketing marketing 4096 Mar 14 11:59 ./Maildir 4767753 4 drwxrwsr-x 2 marketing marketing 4096 Mar 14 11:57 ./Maildir/cur 4767754 4 drwxrwsr-x 2 marketing marketing 4096 Mar 14 11:57 ./Maildir/tmp 4767755 4 drwxrwsr-x 2 marketing marketing 4096 Mar 14 11:57 ./Maildir/new 4767756 0 -rw-r--r-- 1 marketing marketing 0 Mar 14 11:57 ./Maildir/dovecot-shared >From there, the namespace is visible from all the IMAP accounts. Now, if a user creates a new folder in this public namespace, here is what I get: 4767757 4 drwx--S--- 5 brice marketing 4096 Mar 14 12:05 ./Maildir/.test 4767758 4 drwx--S--- 2 brice marketing 4096 Mar 14 11:59 ./Maildir/.test/cur 4767759 4 drwx--S--- 2 brice marketing 4096 Mar 14 11:59 ./Maildir/.test/new 4767760 4 drwx--S--- 2 brice marketing 4096 Mar 14 11:59 ./Maildir/.test/tmp 4767761 0 -rw-r--r-- 1 brice marketing 0 Mar 14 11:59 ./Maildir/.test/dovecot-shared 4767762 4 -rw------- 1 brice marketing 6 Mar 14 11:59 ./Maildir/subscriptions As you can see: the cur,new,tmp dir don't have the right permissions (they're not rw for the group), and moreover, the 'subscriptions' file has the same problem. The result is that any other user don't have access to this directory even if it is in a public namespace. Now, the question, is: is that setup could work only with virtual users setup with a static uid/gid ? Is there a mean to implement what I want ? Does using symlinks instead of the namespace could work ? Regards, -- Brice Figureau <brice+dovecot(a)daysofwonder.com>

[Dovecot] mbox to maildir conversion - good idea regarding Outlook?

Hi list, first of all, many thanks to the Dovecot authors for supplying an IMAP server that works well with M$-Outlook! I have used UW-imapd for quite a while and was annoyed by frequent "imap...timeout..." error messages. Now I'd like to give maildir format a try because I want to use email sub-folders. What are other Outlook users' experiences with maildir? Is it as stable as mbox? Regards Gerhard

[Dovecot] Limiting Dovecot access by user-spesific ip addresses?
by Timo Neuvonen 13 Mar '06

13 Mar '06

Hi, Is there any possibility to limit access to mailboxes by user-spesific ip addresses? So, I'd like to have a configuration which by default restricts reading emails to company's own ip-address range. So far, this could be achieved by a basic firewall rule, but not any more the following: However, there is need for a few users to access their emails from world-wide internet, so there should be a possibility to define for certain users an option to skip the allowed address range check.

[Dovecot] Suggested patch: retain user's group privileges after logging into IMAP
by Lior Okman 11 Mar '06

11 Mar '06

Hi, I'm attaching a suggested patch that lets an authenticated user access shared IMAP folders even if the user doesn't directly own the storage, but is a part of a group that has permissions on the storage. This allows for the administrator to setup a shared mailbox with permissions given to a group instead of a user, and allow all of the users that belong to the group to access the mail according to the file-system permissions. What do you think? Is this the right way to do this, or am I missing something security-wise? I'm also attaching a bug fix for the LDAP passdb, where if the password scheme wasn't PLAIN, the password would be cleared from memory before being used to authenticate the user, and the authentication would fail. Regards, Lior

Hi all, I just started working with Dovecot and I'd like to use it for my organization, but I've run into a little problem. So far I love it and it does what I need. One thing we need is to be able to write to multiple mailbox formats on a per user basis (mbox or Maildir), and it does just that. I want users to be able to choose their format, and I can let it autodetect for me. The way I do that is I have Maildrop filters check for the presence of a ~Maildir, and if it finds that it writes to it, otherwise it writes to ~mbox. Dovecot is the only IMAP server I've found to read either or without hard coding one or the other in the config file. The problem: We also want failover. Mail/home directories are NFS mounted. I was planning to setup two dovecot servers, and noticed that whenever one server writes its temp files to the mail directory, if another server tries to read it you get a segfault and the child process fails and dies. So it basically looks like only one server can own the files, and it won't share. I considered trying to set the INDEX option on the mail boxes to write local indexes, but if I try to specify something like: default_mail_env = INDEX=/var/indexes/%d/%n, it doesn't work. Sure I can make it work by putting in a mailbox format before the INDEX, but then I can't use the autodetect which I need. Here's the syslog error: kernel: imap[13689]: segfault at 00007fffffe38000 rip 00002aaaaad3823f rsp 00007fffffe351f0 error 4 Any solutions? I really need this to work badly, or we may have to rethink our entire mail strategy. I'm also using the latest version 1.0beta3. I considered namespaces, but correct me if I'm wrong, you can't setup two namespaces and have it pick the first mailbox format available like the autodetect feature does. I tried seting up namespaces for both mbox and Maildir, but it just creates both. Please help someone. I need a solution to present to my boss, even if that means we have to run one server until the bug is fixed in the next version. Thanks, Adam

[Dovecot] POP3 extension to accept UIDL ranges?
by Matthias Andree 10 Mar '06

10 Mar '06

Greetings, is anybody aware of an extension to POP3 that supports UIDL ranges? It would be very useful for keep-messages-on-server setups (yes, I know, IMAP4 domain) to be able to do UIDL 21-42 to obtain just these 22 UIDs (this would always have to be a multi-line reply, just like UIDL without argument). If such a thing does not exist yet, perhaps a keyword such as "[X]UIDLRANGES" in the CAPA response might advertise this feature to clients. Regards, -- Matthias Andree
