[Dovecot] Deliver Root Setuid
by Láďa 03 Dec '06

03 Dec '06

Hi, I just configured my Postfix installation to deliver via Dovecot LDA. But because I use separate uids for virtual domains I had to set deliver to be setuid root. Altough I find this as frequent answer to this problem with deliver LDA I am not a 100% sure - basically because I try to avoid root setuids as much as I can. What should be better solution - to have all mailboxes with one owner or this setuid binary? My main reason for separate uids was filesystem quotas for whole domain. But my mail partition resides on XFS so I can do the same with directory quotas and I also noticed changes in quotas which should be also per domain in some next release or with patch. Thanks for any advice and also thanks for all great work on Dovecot. Láďa

Do we really need to increase individual user maxfiles to >1024 ? Dovecot is set to 31768 so it is definately the user process here. Anything I can tweak in dovecot.conf to prevent this? Thanks!

[Dovecot] Dovecot hung or what?

Here is my first major problem with dovecot. I am running rc15 on FreeBSD 6.1. I run dovecot supervised by DJB's daemontools. I run only the pop3 service. A colleague informed me that pop3 service was simply not responding. They could not rcv mail. When I checked the server, tail-ing dovecot.log, here is what was scrolling: [wash@nbi ~]$ tail -f /var/log/dovecot.log dovecot: Nov 23 18:04:11 Info: pop3-login: Disconnected: Inactivity: rip=196.200.37.94, lip=62.8.64.64 dovecot: Nov 23 18:04:11 Info: pop3-login: Disconnected: Inactivity: rip=196.200.42.212, lip=196.200.36.2 dovecot: Nov 23 18:04:12 Info: pop3-login: Disconnected: Inactivity: rip=196.200.35.130, lip=62.8.64.64 dovecot: Nov 23 18:04:13 Info: pop3-login: Disconnected: Inactivity: rip=168.144.108.27, lip=62.8.64.64 dovecot: Nov 23 18:04:14 Info: pop3-login: Disconnected: Inactivity: rip=168.144.108.8, lip=62.8.64.64 dovecot: Nov 23 18:04:17 Info: pop3-login: Disconnected: Inactivity: rip=196.200.39.169, lip=62.8.64.64 dovecot: Nov 23 18:04:17 Info: pop3-login: Disconnected: Inactivity: rip=41.220.126.2, lip=196.200.38.2 dovecot: Nov 23 18:04:17 Info: pop3-login: Disconnected: Inactivity: rip=196.200.39.169, lip=62.8.64.64 dovecot: Nov 23 18:04:18 Info: pop3-login: Disconnected: Inactivity: rip=196.200.37.174, lip=62.8.64.64 dovecot: Nov 23 18:04:19 Info: pop3-login: Disconnected: Inactivity: rip=196.216.68.230, lip=62.8.64.64 dovecot: Nov 23 18:04:22 Info: pop3-login: Disconnected: Inactivity: rip=196.200.45.54, lip=62.8.64.64 dovecot: Nov 23 18:04:26 Info: pop3-login: Disconnected: Inactivity: rip=196.200.35.130, lip=62.8.64.64 dovecot: Nov 23 18:04:27 Info: pop3-login: Disconnected: Inactivity: rip=196.200.45.54, lip=62.8.64.64 dovecot: Nov 23 18:04:28 Info: pop3-login: Disconnected: Inactivity: rip=41.220.126.2, lip=62.8.64.64 dovecot: Nov 23 18:04:28 Info: pop3-login: Disconnected: Inactivity: rip=196.207.23.28, lip=62.8.64.64 dovecot: Nov 23 18:04:31 Info: pop3-login: Disconnected: Inactivity: rip=82.109.38.129, lip=62.8.64.64 dovecot: Nov 23 18:04:32 Info: pop3-login: Disconnected: Inactivity: rip=41.222.12.121, lip=196.200.36.2 ^C [wash@nbi ~]$ su Password: nbi# sh /usr/local/etc/rc.d/svscan.sh stop Stopping svscan. nbi# sh /usr/local/etc/rc.d/svscan.sh start Starting svscan.

Odhiambo WASHINGTON writes: > | Courier 4 POP migration to dovecot. > > This should be very easy, I think. > Once you know the uidl format used by Courier 4 POP. The migration is Courier 4 to Dovecot using Maildir format. I used some scripts I found on the net and adapted them. I got everything to come over (ie imap subscriptions), except POP3 UIDs. My Courier POP3-uid files look like: /2 19 1164413643 <message file name>,S=28985:2,S 29648 10:1164413643 <message file name>,S=5913:2,S 6042 11:1164413643 <message file name>,S=5121:2, 5236 12:1164413643 <message file name>,S=5257:2, 5373 13:1164413643 <message file name>,S=5106:2, 5215 14:1164413643 <message file name>,S=5618:2, 5745 15:1164413643 <message file name>,S=30619:2, 31353 16:1164413643 <message file name>,S=34785:2, 35609 17:1164413643 <message file name>,S=6695:2, 6852 18:1164413643 My pop3_uidl_format is pop3_uidl_format = %08Xu%08Xv Looking at what Dovecot generates on a brand new pop account the files look like: 1 1164413643 29 10 <message file name> 11 <message file name> 12 <message file name> 13 <message file name> ... and more with the same format... So I write an AWK script which creates the proper first line and gets for each line the message ID and message file name. Yet after I do the conversion and run a pop3 client against the migrated pop account, old mails are re-downloaded.

I just added auth caching with pam, and I'm getting this error: dovecot: [ID 107833 mail.error] auth(default): file passdb.c: line 178 (passdb_init): assertion failed: (passdb->passdb->default_pass_scheme != NULL || passdb->passdb->cache_key == NULL) A google search turns up <http://www.dovecot.org/list/dovecot-cvs/2005-March/004117.html> which looks approx like this except the assertion above is in passdb.c. Anyway, is this a known problem in 1.0.beta8? I've been reluctant to upgrade to the rc's due to all the problems. -frank

[Dovecot] [IDEA] Shared Folders via LDAP Lookups
by Gavin Henry 03 Dec '06

03 Dec '06

Hi All, We've been thinking a lot about the 2 different ways dovecot implements shares; namespaces and symlinks. We currently use the symlink version for our clients and they use the create_dovecot_shares.pl tool we did at: http://dovecot.org/tools/ Our idea is either in the namespace declaration or if a folder has a dovecot-shared file/symlink, have a ldap lookup defined in say, dovecot-ldap-shares.conf or dovecot-ldap.conf, that queries a dn and looks for memberUID or a group dn, then those uids/groups can get into the IMAP maildir. Obviously the original folder would need to be owned by some predefined user, e.g dovecot etc. Then it's just a simple matter of adding a new memberUID/group to the share listing. We can do a custom dovecot.schema if needed (for say a dovecotShare attribute etc.), as long as we get dovecot a Private Enterprise Number from: http://www.iana.org/cgi-bin/enterprise.pl If Timo hasn't already got one, but I can't see one in: http://www.iana.org/assignments/enterprise-numbers Thoughts? -- Kind Regards, Gavin Henry.

[Dovecot] POP3 protection
by Jos Chrispijn 03 Dec '06

I have some users that I will not allow to use POP3 thru my system, but force them to use webmail. Would it be possible to put an extra option in dovecot.conf to force this: # ----------------------------------------------------------------- # Logon processes # user = <username>,<password> # ----------------------------------------------------------------- user = johndoe,another_secret_password user = mike,trouble_in_paradise If unix user johndoe logs on, he cannot fetch mail thru POP3 for he has a differect password from his logon password. thanx for listening, Jos

Re: [Dovecot] Can't drop root group privileges

An update on my problem dropping root group privileges. I discovered this is a problem for a user if they are in the system group (gid 0). If I remove the user from the system group, and leave them in their primary group, I don't see the error. I've tried setting first_valid_gid to something like 4, hoping dovecot would filter out gid 0, but that doesn't work. Still searching for an answer... Jackie > > Hi all, > > I need your insight.

[Dovecot] small mbox and index files problem

03 Dec '06

Dovecot version: 1.0-0_33.rc15 built by atrpms Operating system: Redhat EL4 CPU architecture: x86 Filesystem you used: mailboxs via nfs to fileserver using xfs Just upgraded from 1.0-0_20.rc7 to 1.0-0_33.rc15 built by atrpms and we had previously set mbox_min_index_size to 1024 (1Mb) and now all mailboxes (mbox format) that are under this size are not able to be opened and throw an "Internal error occured. Refer to server log for more information." using either Thunderbird or Outlook Express, both of which are recent versions. The small mailboxes can be opened after turning mbox_min_index_size setting back to 0, at which time it creates indexes. There is nothing in the syslog file. I am looking in the right place as I can see the dovecot startup message. paul --

Re: [Dovecot] dovecot:IMAP(user) killed with signal 6
by Spil Oss 03 Dec '06

03 Dec '06

Thanks Timo! Since I've been running rc10 again dovecot stopped aborting. By the way, when I used the create_shares.pl script, it created a symlink for every file in the directory to be shared. Simple symlinking the dir seemed to 'almost' work but for the keyword file errors. Upgrading to rc15 fixes the problem as well, the Permission Denied message still comes up, but dovecot no longer aborts. Will try the create_shares.pl script again and see where my symlink-config is wrong. FWIW I wouldn't want any undocumented behaviour in dovecot just because I'm a stupid twat... Kind regards, Spil.

[Dovecot] Problem with rc10, perhaps 11-15
by Steven F Siirila 03 Dec '06

03 Dec '06

I don't recall if I mentioned this on the list, but when you are configured with mbox format, and a user has no Dovecot index files yet, and the config is such that mbox_min_index_size is set to non-zero, non-default (128 in my test case), dovecot deliver fails. Commenting out "mbox_min_index_size" fixed the problem, and the indexes then get created. This problems exists in RC10 -- I'm mentioned this in case it still exists in the latest revs so it can get fixed before release. -- Steven F.

[Dovecot] IMAPS works, IMAP does not
by Peter Lindgren 03 Dec '06

03 Dec '06

Hello! I have a simple (I think) problem. I have had IMAPS working fine for a long time. Now I want to start to use IMAP and STARTLS, since my mobile SonyEricsson P900 can't use IMAPS directly. But I can't connect even locally to the IMAP port (143), no-one listens there according to netstat (*.imaps is in LISTEN state). I have the following settings in my /etc/dovecot.conf: protocols = imap imaps ssl_cert_file = /etc/ssl/dovecotcert.pem ssl_key_file = /etc/ssl/private/dovecot.pem disable_plaintext_auth = no login_user = _dovecot login_greeting = Dovecot@casiopea ready. mail_read_mmaped = yes mmap_no_write = no protocol imap { login_greeting_capability = yes } protocol pop3 { } auth_verbose = yes auth default { mechanisms = cram-md5 digest-md5 passdb passwd { } userdb passwd { } user = root } I have restarted (SIGTERM) dovecot to be sure that dovecot is restarted. I still run 1.0beta3 on OpenBSD. TIA, Peter -- Peter Lindgren, dataingenjör E-post: peter "at" norrskenkonsult punkt com http://www.norrskenkonsult.com

[Dovecot] shared folder
by T. Horsnell 03 Dec '06

03 Dec '06

The dovecot wiki says: The only way to implement shared folders with Dovecot 0.99.x is to create a "shared userid" which all of the users log in to read mail. Does this mean that folders owned by that shared uid can be *simultaneously* manipulated by multiple users logged in to that shared uid? This doesnt seem to be the case on my dovecot-0.99.11-4.EL4 system, and before investigating further I just wanted to check whether it should be possible or not. Cheers, Terry.

[Dovecot] Nested folders in FS supported yet?
by Sweth Chandramouli 03 Dec '06

03 Dec '06

The last time I checked, dovecot didn't support having nested IMAP folders be implemented via actual nested maildir folders in the filesystem, but that feature was on the "someday maybe it'll happen list", IIRC. I can't find any recent mention of that feature or its absence on the web or in the list archives; is it still on the someday list? (If it isn't implemented yet, does anyone know of an IMAP server that DOES support it?) Thanks, Sweth. -- Sweth Chandramouli sweth(a)ethicalhomes.com - http://EthicalHomes.com/ Thinking about buying a home, but feel like the local real estate market has left you behind?

[Dovecot] Heimdal & gssapi.h
by Chris Wakelin 03 Dec '06

03 Dec '06

I've had some trouble compiling GSSAPI on SuSE Enterprise 9 using Heimdal. It turns out that this installation has /usr/include/heimdal/gssapi.h rather than gssapi/gssapi.h. krb5-config correctly sets -I/usr/include/heimdal in the CFLAGS. Looking back, there was a similar issue a few months ago:- http://www.dovecot.org/list/dovecot/2006-July/014945.html I'm a complete newbie to autotools but here's my attempt at a patch inspired by http://ximbiot.com/cvs/cvshome/dev/patches/gss - which I Googled for ;) I was hampered by the version of aclocal (and possibly the rest of autotools) being out-of-date on SuSE Enterprise 9 ...

[Dovecot] Can't remove folder
by Leroy van Logchem 03 Dec '06

03 Dec '06

Hello, Here is a 'me too' somewhat like: http://www.dovecot.org/list/dovecot/2006-January/010759.html Example scenario: /u/username/Mail/subfolder/somebox subfolder is a directory somebox is a mbox When I use Thunderbird's "Delete folder" function on the somebox the message appears: "Target mailbox doesn't allow inferiour mailboxes". Thunderbird, by default, tries to move it to Trash instead of deleting it directly. When I change the preference to "Remove it immediately" it works. Which component is at fault here: - limitation of a mbox only setup? - thunderbird should know - limitation of the imap protocol to advice the client it's mbox backed - feature of dovecot, could it be fixed or worked around somehow -- Leroy

[Dovecot] Logging
by Steven F Siirila 03 Dec '06

03 Dec '06

In trying to determine why someone was unable to use port 110 w/STLS (POP) I had great difficulty finding the session in which the user switched to this port from using port 995. This is because Dovecot does not log any port number information. Furthermore, it isn't obvious to me if it logs whether a session was negotiated SSL (via STARTTLS w/IMAP or STLS w/POP) or started out SSL (ports 993 and 995). If this seems reasonable, I can whip up a patch to log this information. However, I'd rather see Dovecot 1.0 released first. -- Steven F.

[Dovecot] authentication
by eric 03 Dec '06

03 Dec '06

Good evening from Aotearoa; First some details: Clients are all Outlook2003 on XP yawn Server is Suse 9.3 Samba, postfix, fetchmail and dovecot 1.0 rc13 I succesfully installed Dovecot on my test network at home, but at the job site its a mystery. I seem to be able to get one client to authenticate but not another. And only if i created a password file consisting of logins and no passwords. Dovecot won't use standard unix passwd successfully. So here is the conf: base_dir = /var/run/dovecot/ protocols = pop3 listen = *:110 disable_plaintext_auth = no ssl_listen = ssl_disable = yes login_dir = /var/run/dovecot/login login_user = dovecot login_greeting = Dovecot ready. mail_extra_groups = users mail last_valid_uid = 2000 pop3_uidl_format = %08Xu%08Xv protocol lda { # Address to use when sending rejection mails. postmaster_address = postmaster(a)example.com } auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@ auth_debug_passwords = yes auth default { mechanisms = plain passdb passwd-file { args = /usr/local/etc/passwords } userdb passwd { } user = root default_mail_env = mbox:/var/spool/mail/:INBOX=/var/spool/mail/%u And here is a sample of two of the syslogs.: I am not worried about the UID warning,I was try to login on from various clients.

[Dovecot] Problems using Squirrelmail / Dovecot / Sendmail / Fedora Core 6 - ERROR: Connection dropped by IMAP server
by Alexander Lapajne 03 Dec '06

03 Dec '06

Hello I just installed Fedora Core 6 and I'm having problems with SquirrelMail. I'm using Squirrelmail/Dovecot/Sendmail and when I log into Squirrelmail and try to view any folder that contains any messages I get: ERROR: Connection dropped by IMAP server. Query: SORT (ARRIVAL) ISO-8859-1 ALL Now, I've tried to disable server side sorting in Squirrelmail but that only leads to a new error message: ERROR: Connection dropped by IMAP server. Query: FETCH 1:* (FLAGS UID RFC822.SIZE INTERNALDATE BODY.PEEK[HEADER.FIELDS (Date To Cc From Subject X-Priority Importance Priority Content-Type)]) I'm using the default setup and POP3 mail is working. Using Thunderbird I can read email using POP3. So the problem only appears when using Squirrelmail. I had the exact same setup in Fedora Core 5 and it was working perfectly. Same config files and everything. _________________________________________________________ Flyger tiden iväg? Fånga dagen med Yahoo! Mails inbyggda kalender.

Actually I am suggesting to let go SQL only for that and do it with a simple, plain text solution from within the configuration file. That can't be that difficult can it? It Postfix can do stuff with sender_checks and client_checks why using a database for a simple 0 or 1 :-) thanks for your reply, Floor

[Dovecot] %s service variable substitution
by Jim Horner 02 Dec '06

02 Dec '06

I'm using 1.0rc15. We switched over to using deliver LDA and using dovecot's sasl implementation for postfix... In our ldap configuration we were using (similar for password filter) user_filter = (&(objectClass=mailUser)(mail=%u)(mailSettingValue=%s)) The problem is these new services, namely deliver and postfix, are accessing the authentication mechanisms and I am not sure what to put in ldap so the %s can match. Each user currently only has a mailSettingValue=IMAP. This can be expanded for multiple entries. Thanks, Jim

[Dovecot] Quota's with Thunderbird
by Richard Mayhew - Nashua Mobile Broadband Division 30 Nov '06

30 Nov '06

Hi, Does anyone know how to get Thunderbird to correctly report the mailbox quota's? I know Dovecot is correctly enforcing the quotas on the mailbox when using Thunderbird, but Thunderbird reports that the "server does not support quota's" when trying to view the usage? Is Thunderbird expecting something different? Viewing the mailbox through Squirelmail, the quota's are reported correctly, so I would thnk that Thunderbird is where the problem lies. Regards Richard

[Dovecot] lmtp: help needed
by Leonardo Lanzi 30 Nov '06

30 Nov '06

Hi all, parsing the mailing list archive, it seems that the lmtp-server will not be developed soon, so I'm looking for someone that could help me in writing one, even if not the best one. That's why: I've just started to study dovecot, as I was recruited, just about forced, to help The System Manager of our University in the global e-mail migration - more than 37'000 users, 440 mailing lists, everything synchronized with administrative databases and so on - from open-vms (yes... you have not sight problems: OpenVMS ... please don't blame us). In particular, we have (we'd like so much) to directly deliver from a front-end load-balanced anti-spam&virus all "good" messages into maildirs, updating at the same time the indexes for dovecot. Our idea is to write an lmtp, possibly not from scratch; we have already a threaded server, recently born as a raw smtp server to test the antivirus and antispam system under heavy load (before to start the migration), that can be converted to lmtp protocol, but we lack of information on the dovecot API for delivering in a "dovecot-way". As often occurs, we have not months to get it done, therefore _any_ kind of suggestion will be very much appreciated. Thank you all for the help, and patience! -- Leonardo Lanzi Department of Physics - University of Florence - Italy -- PS - Examples of help: 1. "The code is self-explaining, but obviously you're too old to learn: accept to be in the mist, and switch to cyrus" 2. "the following n-functions ... of deliver can accept your data from memory and do all the job" 3. "I've already done everything, download it at the following url..." 3a. "I've already done everything, but you must send me, _before_, your smtp stressing server, or all your tests on latency of irq handlers with 2.6 kernel, or at least one 18-year-old scottish-malt-whisky bottle!"

[Dovecot] Subfolders with Thunderbird and maildir?
by Andrew Z 30 Nov '06

30 Nov '06

I setup a test dovecot-1.0-0.beta8.2.fc5 and left most of the settings as the defaults. In Thunderbird 1.5.0.8 Windows, when I tried to create a subfolder named "subfolder" under INBOX, it showed up as the same level a INBOX and with the name "INBOX^subfolder". I was able to manually create a subfolder using "mkdir ~/mail/test_manual_subfolder; touch ~/mail_test_subfolder/blah" and then subscribing to it. That's too much work. :) Now when I try to create a subfolder of a non-inbox folder, nothing happens (not even an error). Screen shot: http://img452.imageshack.us/my.php?image=subfoldersthunderbird15ao6.png The Dovecot system is Fedora Core 5 x86 and an NFS client for /home. I'm considering switching from Trustix, UW-IMAP, and mbox. I'm also considering changing INBOX to a Maildir (not /var/spool/mail/%u). Andrew

[Dovecot] MAILDIR environment
by adcx＠server101.com 29 Nov '06

29 Nov '06

from docs/mail-storages.txt: "Also as a special case, if MAILDIR environment exists, maildir storage is used with the directory specified in it." Forgive me if this seems obvious, but is this talking about setting MAILDIR as an enivornment variable? I have it set on my system in both /etc/profile and ~/.bash_profile: MAILDIR=/path/to/maildir/ export MAILDIR and have confirmed this worked by running 'echo $MAILDIR'. I've logged the user in question out and then in again, as well as restarting dovecot but it still defaults to checking ~/Maildir when the user logs in. Setting the location using default_mail_env is not an option here as I need the fallback behaviour that occurs when default_mail_env is not set. Any advice appreciated.

[Dovecot] Redundant shared mail store?
by Jasper Bryant-Greene 29 Nov '06

29 Nov '06

Hi guys I'm about to embark on a project replacing a legacy single mail server running proprietary software with a cluster of Dovecot servers. We clearly need a shared mail store for these servers, but we are not happy with simply using a server running NFS as this becomes a single point of failure. What have other people used? AFAICT our options are: * A shared block device (Fibre Channel, iSCSI, ATAoE etc) running GFS or similar to allow multiple servers to access it concurrently * Two or more NFS units, either with built-in support for replication of FS changes and failover, or with scripts for achieving this functionality I prefer option 1, although it's expensive. What have other people used? Do we have other options? TIA -- Jasper Bryant-Greene Director Album Limited jasper(a)albumltd.co.nz +64 21 708 334 / 0800 425 286 http://www.albumltd.co.nz/

[Dovecot] Quota problems on uidlist files
by James Nunnerley 29 Nov '06

29 Nov '06

Hi All, Please excuse me for this somewhat a slightly uneducated explanation of a problem we are experiencing. I'm more a web developer rather than a sysadmin, and have only recently been looking at how exactly dovecot works. We're having a problem when users/groups quotas are reached on our server platform. Our platform bases quotas on groups - i.e. domains, so a single user has a user username and group of their domain; and the domain has a set amount of space available. This means that if they then try and access their email, via either imap or in most cases webmail, it would seem that dovecot is unable to create the dovecot-uidlist file - which makes complete sense, because it's running as that user and under the group as detailed above.. We've tried changing a pre-existing file to have group ownership of nobody, but from what we can gather, this file is not actually updated, but deleted and recreated when changes occur. One solution would be to take the dovecot-uidlist file out of the mail directory structure, on which the quotas are enforced, but this is not configurable in dovecot. Alternatively, having someway of changing to ownership of the file would also get around this problem. Does anyone have any experience of either a work around for this, or something which we can change in dovecot that will allow users to create a dovecot file, even if they are over quotas? Many thanks James James Nunnerley Applications Developer Namesco Limited

Hi, I would like to supply a few users with extra_fields. All users are found by PAM first so the userdb passwd-file doesnt seem to be used. How to alter the lookup sequence? We can't remove the accounts from the central passwd, just for Dovecot. Thanks, Leroy

[Dovecot] Authentication
by eric 29 Nov '06

29 Nov '06

Try as I may, I cannot get Dovecot to allow anything but blank passwords listed in a custom file I made for the purpose. It will not recognise anybody in passwd. Only using POP3 on an internal network so little danger of incursions. Once I created a password file with user names and no password, one user could login (from Outlook 2003) but another could not. Telnet test also fails to authenticate. I have allowed the group to write to the /var/spool/folder Syslog simply showed authentication failed. Relevant bits of my config: disable plain text = no mail extra group = users pop3 uidl format %08Xu%08Xv pasted direct from the help I have un commented auth user name characteres mechanisms = plain and I have set auth debug passwords = yes user = root System: Suse 9.3 Dovecot 1.0 rc13 Any ideas? -- John McC

Our users tend to use one of the following: Apple Mail Entourage (basically Outlook for Mac) Outlook Outlook Express Thunderbird and then there's the webmail system we provide. Apple Mail has virtually no limit on messages it will handle. I currently have over 500,000 emails in my Apple Mail. It stores email much like Dovecot; each email is in a separate file. This makes backups a breeze, which a reason to switch to a server that uses maildir. Entourage, Outlook Express and Outlook have problems if the data file exceeds 2GB. This is an ongoing problem and I'm hoping by keeping email on the server, the support headaches will be reduced. I'm not sure what limits Thunderbird has. I use Thunderbird to connect to the main directory for all email and it doesn't seem to have any trouble handling it. Currently, everyone is using POP3 but I want to move to IMAP. (Thunderbird is the only client that connects via IMAP on our systems) The motivation for moving to IMAP is primarily for spam handling. Instead of users contacting us for emails that might be caught as spam, the spam will be moved to a "junk mail" folder. Then the user can peruse the folder themselves to find any legit email improperly categorized as junk. Vacation messages is the other item that is prompting a change. Everyone is screaming for that feature.

[Dovecot] Can't drop root group privileges
by Jackie Hunt 28 Nov '06

Hi all, I need your insight. I've been testing Dovecot on an AIX 5.2 system. Compiled and running fine. We have some users on an AIX 5.1 system, so I'm working on installing it there, so we can do further testing. I'm using Dovecot 1.0 RC15 with OpenSSL 9.0.7e, configured to use port 10143 (imap) and 10993 (imaps). The error I'm seeing in the log is: dovecot: Nov 28 09:23:54 Info: imap-login: Login: user=<jackie>, method=PLAIN, r ip=xx.x.xxx.xxx, lip=xxx.xx.xxx.xx, TLS dovecot: Nov 28 09:23:54 Error: IMAP(jackie): We couldn't drop root group privil eges (wanted=200, gid=200, egid=0) dovecot: Nov 28 09:23:54 Error: child 860274 (imap) returned error 89 I've seen this error reported on the list, with the suggested resolution being to set the first_valid_gid = 0 in dovecot.conf. I've tried that, and nothing changes. Any help would be greatly appreciated!

[Dovecot] POP3 && Folders
by Timothy White 28 Nov '06

28 Nov '06

I'm sure this has come up on the list before... I have a number of accounts normally only accessed via IMAP, and for this reason, there is a global sieve script for all users (also required for the spam filtering). What this means though, is that ever users has 3-4 set folders, that are forced on. I now have a few users that want to use POP3. Is there a way to make it download all messages, in all folders, rather than just the inbox? I'm using Maildir's Thanks Tim -- Linux Counter user #273956 Don't email joeblogs(a)scouts.org.au
