Hi all, My mail spools (mbox format) keep getting corrupted with .99.x. I was thinking of running dovecot-stable-20050709.tar.gz ... is this fairly stable? Also, can I use the .99 config file with that code? Thanks! -MAtt

[Dovecot] Dovecot without a chroot
by Matt Juszczak 12 Jul '05

12 Jul '05

Hi all, We're running dovecot without a chroot (mail admin's request), but we're running it as a non-priv'd user with proper firewall setup. Does this seem to be an OK and average setup? Or is it considered a MUST to chroot something like the imapd daemon, etc. Thanks! -Matt

[Dovecot] multiple instances of dovecot ?
by Flavien 12 Jul '05

12 Jul '05

Hello, I got a dovecot server running on a Debian Linux machine. I'd like to run another instance of it. I start it with another config file with debug output on stderr. The auth parameters are different : dovecot1: Imapd only, listens on 143, auth=/etc/passwd dovecot2: Imapd only, listens on 144, auth=mysql It kinda works... But... How does one instance of it recognizes the right "imap-login" it should talk to ? What happens in my tests, you guess it: dovecot1 talks to imap-login2, trying to authenticate users that are in /etc/password against mysql... # dovecot -F -c dovecot-config2.conf dovecot: Jul 05 22:49:03 Info: Dovecot starting up dovecot-auth: Jul 05 22:49:04 Info: MySQL: connected to localhost dovecot-auth: Jul 05 22:49:04 Info: Login process 6 connected dovecot-auth: Jul 05 22:49:04 Info: Login process 7 connected dovecot-auth: Jul 05 22:49:04 Info: Login process 6 sent handshake: PID 26368 dovecot-auth: Jul 05 22:49:04 Info: Login process 8 connected dovecot-auth: Jul 05 22:49:04 Info: Login process 7 sent handshake: PID 26369 dovecot-auth: Jul 05 22:49:04 Info: Login process 8 sent handshake: PID 26370 dovecot-auth: Jul 05 22:49:27 Info: Login process 9 connected dovecot-auth: Jul 05 22:49:27 Info: Login process 9 sent handshake: PID 26374 dovecot-auth: Jul 05 22:50:02 Info: Login process 10 connected dovecot-auth: Jul 05 22:50:02 Info: Login process 10 sent handshake: PID 26402 dovecot-auth: Jul 05 22:50:02 Info: MySQL: Performing query: SELECT password FROM users WHERE uid='flavien' dovecot-auth: Jul 05 22:50:02 Info: mysql(flavien): Unknown user 'flavien' is not known to the sql db. It's thunderbird trying to get my regular mail using the config1 on port 143, and it has nothing to do with the instance 2 whose output I'm just looking at !!! Any hint ? A+ Flavien.

[Dovecot] Creating encrypted passwords for new users /etc/imap.passwd
by John_R._McWade 09 Jul '05

09 Jul '05

Hello. I've been attempting to locate information on how to actually create the encrypted passwords for a new user in /etc/imap.passwd file. Im really going into this blindly, not having ever used dovecot before, and really just need to be pointed to any existing resources on this topic. This is a setup of dovecot (w/ sendmail,squirrelmail) on FC2. I've got one successful auth so far as a test user, with their info cut/pasted directly from /etc/passwd (it works) whereas using {PLAIN}password causes dovecot to drop the connection with an aborted login. So what I'm actually looking for is a resource or a quick response regarding the actual creation of the encrypted password in /etc/passwd style. Any clues on where I should look for this info? John

[Dovecot] stat() failed with mbox /var/mail/%u
by Jungshik Shin 08 Jul '05

08 Jul '05

Hello, Over the last 12 hours or so, I've been wrestling with a mysterious dovecot issue. After upgrading a mail server I'm helping my friend with maintaining from Fedora Core1 to Fedora Core4, I realized that I couldn't use UW-IMAP4 anymore (well, I can compile it myself, but it turned out that UW-IMAP was the main cause of the server's having load average as high as 30 from time to time so that I decided to move onto dovecot). Although I loved to migrate to maildir, I didn't dare to tackle the migration (I have a lot more important things to do :-)) to maildir. Instead, I thought that dovecot's indexing of mbox files should make the performance of the server a lot better than UW-IMAP. (in addition, we upgraded the HW from P3 800MHz single to P4 dual 3GHz). Last night, I experimented with several mboxes of one user's account (INBOX in /var/mail/<userid> and others in ~/mail/) and it worked perfectly well. So, I moved mboxes of other users and launched 'dovecot' informing users that the mail server is back up again. However, it didn't work with inbox (for IMAP) and POP3. There's no problem accessing mail folders in '~/mail', but accessing /var/mail/%u (inbox for IMAP) and using the same folder with POP3 didn't work. The error I got in the log file is: Jul 8 01:17:24 biosoft dovecot: pop3-login: Login: xyz123 [::ffff:1xx.2yy.zz.178] Jul 8 01:17:24 biosoft dovecot: POP3(xyz123): stat() failed with mbox file /var/mail/xyz123: Permission denied Jul 8 00:34:45 biosoft dovecot: imap-login: Login: xyz123 [::ffff:1xx.2yy.zz.178] Jul 8 00:34:45 biosoft dovecot: auth(default): Error sending status request (Operation not permitted) Jul 8 00:34:45 biosoft dovecot: imap-login: Login: xyz123 [::ffff:1xx.2yy.zz.178] Jul 8 00:34:45 biosoft dovecot: IMAP(xyz123): stat() failed with mbox file /var/mail/xyz123: Permission denied ls -ld / /var /var/mail/ /var/mail/xyz123 drwxr-xr-x 23 root root 4096 Jul 7 19:28 / drwxr-xr-x 26 root root 4096 Jul 7 23:35 /var drwxrwxrwt 2 root mail 4096 Jul 8 00:36 /var/mail/ -rw-rw---- 1 xyz123 mail 130751237 Jul 7 23:37 /var/mail/xyz123 I tried various combinations of permissions and ownerships for /var/mail (1777, 2775) and /var/mail/<userid>, but nothing made any difference. I also tweaked mbox locking methods ('dotlock fcntl' or 'fcntl' alone) When I came across this problem with the latest stable (2005-07-06), I went back to FC4's default package (0.99??), but with a slightly different error message in the log file, basically I had the same problem. I kept the default values for most configuration parameters. What I changed are listed below: mail_extra_groups = mail pop3_uidl_format = %08Xv%08Xu protocols = imap imaps pop3s default_mail_env = mbox:~/mail/:INBOX=/var/mail/%u Also attached is the entire /etc/dovecot.conf I'm really desperate to get some enlightening answers on this problem, for which I'll really appreciate you.

[Dovecot] IMAP Folders
by Matt Juszczak 07 Jul '05

07 Jul '05

Hi all, We're using the mbox format and I tried setting up IMAP on my boss's computer tonight. He likes subfolders, and although they work, he can't seem to remove subfolders once he created them, nor create new folders without using something other than his mail client (like mkdir from the command line). Any ideas on this? Does dovecot just not officially support IMAP and subfolders with the mbox format? Or could it be a permissions issue? -Matt

[Dovecot] Username mapping
by nodata 06 Jul '05

06 Jul '05

Hello. We're using dovecot with mysql for authentication, with postfixadmin for the admin web interface. We are moving users from passwd file usernames to email@domain style logins. Is there a better way to allow both sets of usernames (old and new) to work with dovecot than by adding extra copies of rows to the mailboxes table and changing the username? i.e. does dovecot support some kind of username mapping or aliasing? Thanks a lot

[Dovecot] dovecot 1 for production? which one?

Hi, I've been lurking on the list since Spring, planning to replace UW-IMAP with dovecot 1.0 sometime this summer. The recent thread on "1.0" has not given me a good feeling about seeing it before summer's end. So I wonder if I should use dovecot-1.0-test-xx code or dovecot-stable-[date] code (which seems to change every day, how stable is that???). This is confusing, advice please.

[Dovecot] Root password or key access to pop3?
by Matt Juszczak 05 Jul '05

05 Jul '05

Hi all, We're an ISP, and are currently looking for a way for our tech support guys to access customer's email without having shell access to the server, or knowing the customer's password. We'd like to install a custom webmail client that would only show the user's inbox and the ability to delete the messages. The problem is, that we would have to know the user's password in order for my PHP pop3 code to go out and fetch the mail. Is there a way I can setup and/or patch dovecot so that any connection from <said IP address> can use the password "jq3erjq3535" for any account, and it will authenticate them? Or is this some kind of custom patch I would need to write? Thanks! -Matt

[Dovecot] dovecot - outlook users keep getting locked out of imap
by Anthony Kolasny 04 Jul '05

04 Jul '05

Greetings: My outlook users accessing mail via dovecot's imaps have been consistantly getting locked out of their email. It happens about once a week per outlook user. It appears to happen when the are cliking on emails with attachments. When this happens, there are two imap deamons running for that user. I kill both deamons and things start working again. Squirrelmail, thunderbird and pine users haven't had this issue. I'm running a version of dovecot dated dovecot-stable-20050610. All user accounts have their mail on nfs mount points. The INBOX directory is local to the imap server but we have a smtp server that gets this data via nfs. Below is the dovecot.conf info: base_dir = /var/run/dovecot/ protocols = imap imaps ssl_disable = no ssl_cert_file = /usr/local/imaps/certs/dovecot_cert.pem ssl_key_file = /usr/local/imaps/certs/dovecot_key.pem disable_plaintext_auth = yes login_dir = /var/run/dovecot/login login_process_size = 128 login_processes_count = 9 login_max_processes_count = 256 login_max_logging_users = 512 verbose_proctitle = yes mail_extra_groups = mail default_mail_env = mbox:~/mail/:INBOX=/var/spool/mail/%u mmap_disable = no lock_method = fcntl mbox_read_locks = fcntl mbox_write_locks = dotlock fcntl mbox_lock_timeout = 300 mbox_dotlock_change_timeout = 30 mbox_dirty_syncs = yes mbox_very_dirty_syncs = no protocol imap { imap_client_workarounds = outlook-idle } protocol pop3 { } auth default { mechanisms = plain passdb = pam userdb = passwd user = root } Your assistance is greatly appreciated.

Hi, I've setup a postfix mailserver with dovecot and postgres database for virtual domains with virtual users, but I have some problems getting the accounts to work. I've used instruction from this tutorial : http://wiki.dovecot.org/moin.cgi/DovecotPostgresql I want users to be able to get their email with imap or pop3, but I didn't manage to solve this problem. The server makes mbox style user accounts, I can send email to them but when I try to read emails from virtual accounts I get the following error : Jun 28 14:42:52 voodoo dovecot-auth: Login process 10 connected Jun 28 14:42:52 voodoo dovecot-auth: Login process 10 sent handshake: PID 10491 Jun 28 14:42:58 voodoo dovecot-auth: PGSQL: Performing query: SELECT password FROM users WHERE userid = 'user(a)foo.org' Jun 28 14:42:58 voodoo dovecot-auth: PGSQL: Performing query: SELECT '/home/'||home AS home, uid, gid FROM users WHERE userid = 'user(a)foo.org' Jun 28 14:42:58 voodoo pop3(user(a)foo.org): mbox: Can't create root IMAP folder /home/foo.org/mails/user/mail: Permission denied Jun 28 14:42:58 voodoo pop3(user(a)foo.org): Failed to create storage with data: mbox:/home/virtual/foo.org/mails/user Jun 28 14:42:58 voodoo pop3-login: Login: user(a)foo.org [127.0.0.1] Jun 28 14:42:58 voodoo dovecot-auth: Login process 8 disconnected Jun 28 14:42:58 voodoo dovecot: child 10492 (pop3) returned error 89 The error " mbox: Can't create root IMAP folder /home/foo.org/mails/user/mail: Permission denied" appears because, using mbox, the home for virtual accounts is /home/virtual/foo.org/mails/user, where user is allready the mbox file, to the sistem can't create the directory structure for IMAP settings. What I'm doing wrong ? Did someone else got this problem ? Thanks ! -- ------------------------------ Mircea Hutanu voodookid(a)gmail.com ------------------------------

[Dovecot] Automating message archiving
by Steffen Kaiser 04 Jul '05

04 Jul '05

Hallo, I recently stumple over some discussion about Sieve and what's the advantage to integrate it into the server rather than the LDA. Most of the filtering capabilites local users want to have performed are related to the INBOX or more preciesly the way to filter the message coming in. However, there are few tasks left: 1) Auto-archive old mail. 2) Drop old mail. 3) "Seen" mails are moved from INBOX to somewhere else. To 1) Several people love to store each single mail, but because the system becomes very slow when they open a mailbox with, day, 5000 messages (Mozilla even core dumps sometimes); they archive the mails by year or month, if they got elder than, say, 6 month. I do not want to discuss this habbit, it's like it is and I have the trouble with it. To 2) There is the doing of dropping all messages flagged as SPAM into a specific folder. It would be nice if the does messages are deleted, when they grew get elder. To 3) I don't grasp the idea, but it seems that notebook users want to look, what messages are new, flag and download selected ones; when they connect next time the "old, already seen" ones should be invisible, but still accessable on demand in another folder. Maybe it has to do with that the client sometimes reads the whole IMAP INBOX again, instead just the new ones. I've seen this behaviour with Mozilla myself in conjunction with a variaty of IMAP servers now and then. Those things must be user-configurable, of course ;-), I hoped Sieve would solve this problems, but it doesn't. The MVMF mentioned in the mailing list, doesn't as well. Does somebody has some solution for these tasks, besides to setup a cronjob and hack a webinterface? Is there some Dovecot tool that one can use to manipulate the mail storage? UW-IMAP ships such thing (mailutil), but it does not support Maildir and it would be nice, when the Dovecot extensions are created well. Bye, -- Steffen Kaiser

[Dovecot] Authenticate login failed: Unsupported authentication mechanism
by Orchun Kolcu 04 Jul '05

04 Jul '05

Hi, I just switched (or tried to) from UW-IMAP to dovecot. When I try to login through the telnet client I get: 1 NO Authentication failed and in the log I get: imap-login: Authenticate PLAIN failed: Unsupported authentication mechanism If I try to login through the IMAP client (Thunderbird), in the log I get the slightly different: imap-login: Authenticate login failed: Unsupported authentication mechanism Here's the auth setup from the conf: auth default { mechanisms = plain passdb = pam imap userdb = passwd user = root } And here's /etc/pam.d/imap for good measure: auth required pam_nologin.so auth required pam_stack.so service=system-auth account required pam_stack.so service=system-auth session required pam_stack.so service=system-auth The server is a fairly standard Redhat 8 setup. Any idea what's going on? Thanks! -- Orchun Kolcu orchunk(a)fastem.com -- http://www.fastmail.fm - The professional email service

dovecot and squirrelmail configuration successfull!! The problem was: There were many other options related to ssl,which were enabled, like ssl_cert_file,ssl_parameters_file and so on. i disabled them all, and it's working fine now. Now, only, ssl_disable = no is uncommented. Thank you all. Srinivas _______________________________________________ No banners. No pop-ups. No kidding.

[Dovecot] error while connecting from squirrelmail
by Srinivas 01 Jul '05

01 Jul '05

Hi all, I am new to dovecot and squirrelmail and I am trying to configure squirrelmail with dovecot as its imap server. When i disable "Secure Imap (TLS)" option (2-A-7) from squirrelmail configure menu, it's working fine. But when i try to enable tls support, squirrelmail is giving the following error: Warning: fsockopen(): unable to connect to 192.xx.xx.xx:993 in /usr/share/squirrelmail/functions/imap_general.php on line 445 ERROR Error connecting to IMAP server: tls://192.xx.xx.xx. 111 : Connection refused Go to the login page The port numbers of the imap server are as follows: imap_listen 143 pop3_listen 110 imaps_listen 993 pop3s_listen 995 Squirrelmail and the dovecot imap server are running on different machines, so it is essential to enable tls support. All the machines are running Debian Sarge. Can anyone suggest a solution for the above problem ? Thank you. Srinivas _______________________________________________ No banners. No pop-ups.

[Dovecot] Dovecot doesn't use vchkpw properly :(
by Casey Allen Shobe 01 Jul '05

01 Jul '05

Hey all, It seems that dovecot does NOT call vchkpw properly when using vpopmail-style authentication, I can only guess that it reads the vpasswd{,.cdb} files directly. This is indicated by the syslog log for the mail facitily which reads: Jun 30 16:51:30 [vpopmail] vchkpw-smtp: (PLAIN) login success blah@blah.com:24.17.153.137 Jun 30 17:16:25 [pop3-login] Login: blah(a)blah.com [24.17.153.137] Jun 30 17:47:42 [imap-login] Login: blah(a)blah.com [216.57.201.58] pop3-login and imap-login are dovecot processes - vchkpw is never called or there would also be log entries for it. I've verified this with the vpopmail list, who agree that the problem lies within dovecot. This might not be quite so annoying, but we are using vpopmail compiled with the --enable-learn-passwords option, which will populate the password files with cleartext versions of the passwords where they are missing. Because of dovecot not calling vchkpw, this doesn't work for POP3/IMAP logins, only SMTP (using qmail-smtpd). People don't send mail from every account they poll, and we need to get all of the passwords in cleartext form so that we can complete migration to a PostgreSQL password database which multiple applications will use to authenticate. Are there plans to make dovecot use vchkpw in the normal checkpassword manner? If not, I'd like to request it. We will probably switch back to qmail-pop3d and bincimap for the time being to finish collecting passwords if we can't get a quick fix...I think we can do that without much impact.

RE: [Dovecot] LF not found where expected
by Miles Mawyer 01 Jul '05

01 Jul '05

Thanks for the reply. I think I'd found the issue. It seems to be the empty line that is ending up at the top of mail file. I removed that blank line out of one of the mail box files, and it started working without an issue. I'm not sure what is causing the empty line in the mbox file however. Most of my clients use pop3 to download their messages through dovecot. Could this be happening if the client only downloads part of their messages? Pretty easy for me to straighten out, but I didn't know if this was a bug that needed to be addressed. ... Miles Mawyer -=- Webmaster .

[Dovecot] How to lock a user out?
by Kai Wang 29 Jun '05

29 Jun '05

Hi, We are considering to migrate to Dovecot. We can running uw-imap and have a local path which allow us to lock a user by creating a .lockdir directory in the user home directory and put our warning message to .lockdir/mbox. The locked user can still receive messages in ~/mbox. But can not access any messages except ~/.lockdir/mbox. I wonder if Dovecot has any similar feature which we can use to lock a user out without affecting the mail delivery? Kai Wang University of Calgary

[Dovecot] 1.0-test74
by Timo Sirainen 29 Jun '05

29 Jun '05

http://dovecot.org/test/ Not much has happened, but the APPEND bugfix is important since it was broken in test73 (at least). Summer makes me tired and lazy. :( I've been trying to get keywords implemented in maildir. Hopefully works soon.. After that I'll create 1.0-stable2 (ugh. any other naming ideas?) branch of the code before merging the new master/config code. - Fixed APPEND .. I hope? At least works much better than before - pop3_uidl_format = %m now doesn't return broken 0 MD5 sums when the MD5 sum wasn't written in indexes for some reason (eg. appended/copied to INBOX with IMAP and trying to access mail with POP3). - Authentication cache wasn't working when Dovecot was used for proxying - Index cache file wasn't keeping track of how much of the file was deleted, so it may not have ever shrinked - Maildir+NFS: Fixed skipping mails when moving files from new/ to cur/ - Maildir: We didn't notice if messages were directly deleted from new/

[Dovecot] imap corrupted indexes
by Emmett Pate 28 Jun '05

28 Jun '05

I've searched the archives and find a lot of references to corrupted indexes but can't seem to find any solutions. It seems like folks either have the problem or they don't. We recently migrated from a RedHat Linux server to an OpenBSD 3.7 server (both using dovecot). Imap was working flawlessly on the RedHat box but now gives numerous index errors. I then upgraded to dovecot-1.0-test66 compiled from ports - still no luck. Here's an example of the errors: Jun 27 12:02:23 mail dovecot: IMAP(epate): Corrupted transaction log file /home/epate/mail/.imap/INBOX/dovecot.index.log: Keyword record UIDs are broken Jun 27 12:02:24 mail dovecot: IMAP(epate): Lost transaction log file /home/epate/mail/.imap/INBOX/dovecot.index.log seq 7 I found references to "disabling indexing" but they don't say how. Would this be a reasonable temporary solution? Any other suggestions? Thanks for your help, Emmett Pate

[Dovecot] Sudden IMAP problem - UID Errors
by Jamie Heckford 28 Jun '05

28 Jun '05

Hi, We have quite happily been running dovecot with no issues at all for approx. two years now and have had no problem whatsoever. Great work :) BUT (there is always a but!).... yesterday one of our users started complaining that they were having issues with their mail. I checked and although they can still view their IMAP mailbox ok it constantly throws up error messages such as: "The UID of a message changed unexpectedly. This typically indicates a server bug. Your program may not function properly after this. MsgSeqNum 131: Previous UID: 21402, New UID: 21555 Protocol: IMAP" and "Your server has reported a UID which does not comply with the IMAP standard. This typically indicates a server bug. Your program may not function properly after this." This is using Outlook 2003 as the IMAP client, and is only affecting a single user. Server is dovecot-0.99.14 running on FreeBSD 4.9-RELEASE #1: Thu Apr 15 10:00:08 GMT 2004 Anybody seen this before or have any suggestions? Also is there a way I can make the logging more verbose as I only get info on date/user/ip when they login. I did see a --raw-log or similar compile flag, is this whats needed? I suspect this is Outlook being stupid and not dovecot though. Any help would be greatly received.

Hi, 2 or 3 customers have reported that they are having problems downloading their mail via. POP3. I have attached the rawlogs of their transactions and the UID list at the time.

[Dovecot] getpeername() and SSL
by Andreas Goertz 28 Jun '05

28 Jun '05

Hi Timo, first of all: i'm using 0.99.14. You helped me to raw-log the client-IP using something like this in rawlog.c: if (net_getpeername(0, &ip, NULL) == 0) { str = t_strdup_printf("IP: %s\n", net_ip2addr(&ip)); write_full(log_out, str, strlen(str)); } Now i got the problem, that this doesn't work when the client is connected using SSL. After some testing i think, the problem is, that after calling net_getpeername() the ip-family is AF_UNIX, not AF_INET, so net_ip2addr() returns null, but i'm not sure ;-) And i have no clue, how to solve this and find out the ip... Do you have another hint for me? Thanks in advance. Regards, Andreas.

I have verified that ~/Maildir/new actually contains valid e-mails. Does anyone have suggestions on how to debug this problem? A connection is established if I telnet. I use Fedora Core 4. Another problem I have, is changing log_path and info_log_path to something useful. If I change either to i.e. /tmp/dovecot.log, dovecot refuses to start (service dovcot restart) with noe error message. If it helps, my /etc/dovecot.conf is here: http://www.stud.ntnu.no/~grimsrud/info/dovecot.conf.txt -- Lars Karset Grimsrud <grimsrud(a)stud.ntnu.no>

[Dovecot] password scheme
by Nathalie Boulos 28 Jun '05

28 Jun '05

Hi, I have dovecot-0.99.11-1.FC3.4 running on fedora core 3, and authenticating with openLDAP on a remote server. When i try to authenticate, i get the error "Unknown password scheme SSHA". I read that earlier on this mailing list, SSHA was not suported by dovecot. Is it supported now? what should i do to make my password authentication work? The users in the openLDAP database have userPassword {SHA} already used by other services, so i cannot change them. Any suggestions?

I'm using Dovecot 0.99.13 on a fedora core 3 server. I keep getting these errors from time to time. There user ends up retrieving no mail (but no error in their client, be it web mail or pop3 client) What usually fixes it is this procedure: Cp mbox file to mbox_ Remove original mbox Send a test message to recreate mbox. Cat mbox_ >> mbox Problem solved!

[Dovecot] possible bug with incoming mail
by Luke Ehresman 28 Jun '05

28 Jun '05

I've been using Dovecot for a couple months now and am very impressed. Thanks for a great package. However, I have noticed a problem that I haven't been able to solve. When a new message comes into my inbox, the last message that was received is marked as new as well as the new one. I originally thought this was a bug in my client (mutt) but I have verified that the same thing happens with Thunderbird, Sylpheed, mutt, and pine. My configuration is as follows: ------------------------------- using mbox: default_mail_env = mbox:/var/spool/vfolders/%d/%n:INBOX=/var/spool/vmail/%d/%n using imaps Linux version 2.6.11-hardened-r1 (root@gondor) (gcc version 3.3.5 (Gentoo Linux 3.3.5-r1, ssp-3.3.2-3, pie-8.7.7.1)) #2 Thu May 5 13:14:52 EDT 2005 Thanks for any help you can give, Luke

[Dovecot] Dovecot + MySQL no auth
by Dylan Baxter 28 Jun '05

28 Jun '05

I haven't been able to login to my mail server using MySQL authentication and I believe I've found the issue. My POP log says: dovecot: Jun 07 09:58:56 Error: auth(default): sql(dylan(a)domain.com,127.0.0.1): Password query must return a field named "password" dovecot: Jun 07 09:58:56 Info: pop3-login: Disconnected [127.0.0.1] The password field in MySQL is called "passwd". Am I to understand that there is no way around this? I must rename the field to "password"? My config files all check out. I'm pretty sure I'm at a road block here. Any help would be greatly appreciated. Also, aren't there anough Dovecot users to warrant a forum and/or IRC channel? I cant seem to find either (but thank you for the mailing list!). Thanks all for any help! Dylan

[Dovecot] Restrictions on User Basis
by Net Cerebrum 28 Jun '05

28 Jun '05

Hi, I am running dovecot on Fedora Linux in our organization and use IMAP as well as POP3 protocols for mail retrieval. I want to impose the following user based restrictions: (a) I want to permit only selective users to access either POP3 or IMAP server or both. (b) The server can be accessed from LAN as well as WAN. However I want to allow only selective users to be able to access POP3 or IMAP server from the WAN side (or on the basis of IP addresses). What do I need to do to impose these restrictions ? Thanks,

[Dovecot] APPEND issue with Thunderbird
by Todd Burroughs 28 Jun '05

28 Jun '05

I'm getting a strange problem with APPEND and Thunderbird 0.8. This was working fine in the CVS version from June 8 and is not so fine as of June 20. It works fine using Pine. It appears that imap is hanging when trying to append to a folder. Right now, an imap process has the file open for about 1/2 hour. It wrote the headers out, but not the body. When Thunderbird disconnects from it, it closes the file, but does not finish writing the email. Here's the difference in the commands sent by Pine and Thunderbird from rawlogs. These are different accounts. (Thunderbird) (.in file) 2 append "Sent" (\Seen) {520+} Message-ID: <42BAC447.7050901(a)hostopia.com> (rest of headers and message follows) The .out file is empty --------------------------------------- (Pine) (.in file) 00000003 CAPABILITY 03000004 APPEND Sent {392} Date: Wed, 22 Jun 2005 19:35:42 -0400 (EDT) (rest of headers and message follows) 03000005 LOGOUT (.out file) * OK [RAWLOG TIMESTAMP] 2005-06-22 19:36:20 * CAPABILITY IMAP4rev1 SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS 00000003 OK Capability completed. + OK 03000004 OK Append completed. * BYE Logging out 03000005 OK Logout completed. ----------------------------------------- Todd

[Dovecot] FAM support?
by Michael Tibben 28 Jun '05

28 Jun '05

Hi, Is there any planned support for FAM http://oss.sgi.com/projects/fam/ in dovecot? One of my favourite features of Courier IMAP server is that it alerts my email client through IMAP when email has arrived. Regards, Mick
