To say nothing of having built the whole edifice with the integrity, simplicity and elegance, that these changes are possible. I've long felt that doing programming can give one an awed appreciation for Creation. In principio, in the beginning, it is of the essence to get the first principles right....otherwise, everything that follows is a downhill slide to garbage. Timo is like one of the master cathedral builders of the Renaissance.......

[Dovecot] quota warning
by Nicolas Boullis 06 Mar '07

06 Mar '07

Hi, As suggested by Timo, I have tried to implement some warning when the user gets close to his quota limit. The patch is attached. It is configured in the plugin section of the configuration file: quota_warning = 80:0:/usr/local/bin/quota_warning.sh With this one, /usr/local/bin/quota_warning.sh is executed each time a mail brings the total size from below 80% to 80% or above. The second number serves as a limit for the count. The /usr/local/bin/quota_warning.sh script builds the warning message and delivers it with cat << EOF | /usr/lib/dovecot/deliver -c /etc/dovecot-nowarning.conf where /etc/dovecot-nowarning.conf is the same as my normal configuration file, except that it lacks the quota warning option (that is required in a situation where the warning message is large enough to bring over the 80% limit, to avoid a warning loop). Comments are welcome. Cheers, Nicolas Boullis

[Dovecot] user_global_uid - tricky to set
by Alexej Davidov 06 Mar '07

06 Mar '07

Hola! Dovecot should serve virtual mail users. So I've set user_global_uid and user_global_gid in dovecot_ldap.conf to vmail/vmail. Also I've commented auth the user_attrs field. Still Dovecot tries to switch to the uid that is defined in the LDAP entry. It took me some time to figure out, that the only way to prevent this is to set user_attrs = foo=uid,bar=gid or something like this, so Dovecot doesn't have a chance to find the uid/gid. Still it will perform some LDAP lookups. In my oppinion, Dovecot shouldn't try to get the uid/gid from LDAP if the user_attrs field is undefined. I'm using Dovecot 1.0rc24 on Debian sid. Regards, A.

[Dovecot] Disconnects with proxies / new facts
by Michael Kress 06 Mar '07

06 Mar '07

Hi, I just tried the below with the current version 1.0 RC15 and I still got the Problem: telnet gives me the following output: -----8<-----8<-----8<-----SNIP-----8<-----8<-----8<----- +OK dovecot ready.u-ERR invalid command u s-ERR invalid command s e-ERR invalid command e r-ERR invalid command r -ERR invalid command u-ERR invalid command u s-ERR invalid command s e-ERR invalid command e r-ERR invalid command r _-ERR invalid command _ 1-ERR invalid command 1 -ERR invalid command -----8<-----8<-----8<-----SNIP-----8<-----8<-----8<----- The above output results from the following entry: user user_1[ENTER] So now I know that this is no version issue. Can you tell me something on how I can find the solution for this problem? I don't think its a firewall issue, I disabled my Desktop Firewall. On the server I use shorewall, but of course, port 110 is open and it works disabling AntiVir on the client side. The error also occurs when I disable the Server Firewall as well. The error is reproducible on several PCs (I tried 3 PCs). Have you got any hint? Without solving the problem, I have to switch the pop3 server to another one, because this problem is really a crucial one.The only problem is: I loke dovecot. :) Thanks in advance!

When I configure my dovecot server to do just plain pop3 I can telnet from a windows box without any flaw, but as soon as the client uses some pop3 proxy (for example outlook uses avira antivir Mail-AntiVirus Protection), queries to that server fail. A log line looks like this: pop3-login: Dec 05 22:53:24 Info: Disconnected [::ffff:84.165.54.42] Moreover with the proxy activated, a telnet to port 110 (pop3) is not working properly, the cursor stays right behind "+OK dovecot ready." and as soon as I enter a character, the server rejects this character as an unknown command (Without pressing ENTER). As soon as I turn off the Antivir-Proxy the telnet to port 110 runs flawlessly and I can login. So I'd like to know is there anything I can do with this version or is it worth trying the newest version? Is this a known issue?

[Dovecot] 1.0rc25: double INBOX folder (weird)
by Troy Engel 06 Mar '07

06 Mar '07

Let me start off by saying the initial cause was *not* a Dovecot bug. :) If you have the default namespace "INBOX." (Courier emulation mode from the Wiki) and an actual folder in your ~/Maildir/ with INBOX in the name (~/Maildir/.INBOX.Miami), then Dovecot presents them both to the client as the real Inbox in Thunderbird: Account Inbox (3) Drafts Sent INBOX (3) ...where (3) is me representing a new email account; if you click on either INBOX folder (parent or child) they show the same contents of the single Inbox. It was really confusing until I figured out the Maildir was messed up on the backend. Sometime back in 2004 the Courier-IMAP server let one of my (dovecot) testers create a folder called .INBOX.Miami; until the 1.0rc25 upgrade we never even knew it was there - it has been invisible this whole time. I can only assume that a bug in Courier allowed that folder to be created in the first place, I'm not bothering to track it down. Once I upgraded to 1.0rc25 this morning all the sudden there it was -- obviously not Dovecot's fault for putting it there and it was easy enough to fix by hand, but I thought I'd report it in case it exposed some logic gap in the code. If nothing else Dovecot shouldn't have duplicated the INBOX view to the client, and instead just showed it as a regular folder - yes? -te -- Troy Engel | Systems Engineer Fluid, Inc | http://www.fluid.com

[Dovecot] Migration
by John s 06 Mar '07

06 Mar '07

Hi, I have a Mailserver setup with Qmail+Vpopmail+courier-imap with 2000 users.The authentication in vpopmail was in plaint text file based.Right now the issue is while opening a user email box with 50-100 mails it is opening fastly.Butfor email-boxes with attachments and increased number of mails it take long time to open the Imap connection. So I would like to change the Imaps to Dovecot.Please suggest if I can migrate from courier-imap to dovecot with vpopmail and qmail without changing the present username and passwords. Thanks in advance for any help. Regards John

[Dovecot] new crashes: is the index/mail cache endian neutral?
by Dan Price 06 Mar '07

06 Mar '07

Part of our migration plan takes our users from one endianness to another (big to little). Will the index and mail cache files survive? I'm seeing some new core dumps as the first test user is migrated, which makes me think... not. What about if we want to build dovecot 64 bit in the future? Will that cause problems too? Stack trace is below the log messages. I've edited the user's name out and replaced it with foobar, and cleansed out a few sensitive things. -dp dovecot: Mar 01 08:46:49 Info: imap-login: Login: user=<foobar>, method=PLAIN, r

[Dovecot] messages lingering in .Trash/new instead of .Trash/cur
by Glenn Leavell 06 Mar '07

06 Mar '07

We're running Dovecot rc15 on Solaris 9, providing IMAP access to e-mail stored in Maildir++. I've noticed that a significant number of message files are currently sitting in the directories ~/Maildir/.Trash/new/. I would have expected that all messages in .Trash would be in the /cur subdirectory (as most are), and I'm not sure how they're landing in /new. If I connect to Dovecot and run something like the following, the messages all *do* immediately end up in .Trash/cur/ : x select blah * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags * permitted. * 4 EXISTS * 0 RECENT * OK [UIDVALIDITY 1150071896] UIDs valid * OK [UIDNEXT 5] Predicted next UID x OK [READ-WRITE] Select completed. x copy 4 "Trash" x OK Copy completed. Most of our users are using Thunderbird, and after looking at various outputs of rawlog, TB seems to be simply issuing uid copy commands to "Trash" like the ones above when a user deletes a message. Do any of you know what IMAP interaction with Dovecot can lead to message files appearing in .Trash/new/ ?

[Dovecot] Driving quota out of a database.
by David Craigon 06 Mar '07

06 Mar '07

Hi there, I'm using postgres as a userdb for dovecot. I'm am trying to get the quota plugin to work. I have a column in my table that returns the quota in KB. I am using the postgres expression "('maildir:storage=' || mailstore_control.mailbox.quota) AS quota" as recommended in the manuals. This expression is NULL to start with, which I take to mean unlimited quota. Trouble is, if I change it to a value, and then change it back to null, I don't seem to go back to unlimited quota. I'm using maildir++ quotas. What gives? :-) David Griffin Information Systems Ltd 20 St Christopher's Way, Pride Park, Derby DE24 8JY www.griffin.com <http://www.griffin.com/> Registered in England and Wales.

[Dovecot] Replacing qmail + vpopmail with: sendmail + dovecot
by Oliver Schulze L. 06 Mar '07

06 Mar '07

Hi, I wonder if it posible to replace qmail + vpopmail with sendmail + dovecot? The idea is like this: - use sendmail + milter API to filter spam/virus and deliver the email to the dovevot MDA (LDA) - dovecot should save the email to the directory as specified in the vpopmail DB - maintain the vpopmail BD (users + passwd) - use dovecot pop3/imap for the clients - use sendmail again to receive the email from the pop3/imap users and deliver the email to the internet as usual. Anyone has done this? It is posible in the paper, in the real world? many thanks Oliver -- Oliver Schulze L. | Get my e-mail after a captcha in: Asuncion - Paraguay | http://tinymailto.com/oliver

[Dovecot] MBOX to MAILDIR conversion
by Marc Perkel 05 Mar '07

05 Mar '07

Thinking about going from mbox to maildir. Started with mbox way back when but thinking about making the conversion. The main reason is that I use rsync for backups and when these huge mailboxes are touched I have to copy the whole thing. With maildir I only copy the files that change. So - my questions is - what's the easiest way to make this happan. I assume there are conversion utilities. I'm using Exim as an MTA. Also - using Ext3 for the file system on a Raid 10 array. Backup server will run Ext3 Raid 1. Is the number of files in one directory going to be a problem? And - any tip/tricks would be appreciated. Things to look out for? Still in planning stage. Thanks in Advance.

Hello folks -- I'm using Debian etch and I've got Mysql 5.0, Dovecot 1.0rc15 and DSpam 3.6.8... I've downloaded the mysql-dspam-plugin code, and it builds without errors. But when trying to start Dovecot I get: Starting mail server: dovecotIEffective uid=65534, gid=65534 ILoading modules from directory: /usr/lib/dovecot/modules/imap Emodule /usr/lib/dovecot/modules/imap/lib_dspam.so: dlsym(dspam_init) failed: /usr/lib/dovecot/modules/imap/lib_dspam.so: undefined symbol: dspam_init Error: imap dump-capability process returned 89 Any help with how to fix this would be great! I'm not really a programmer so I'm not quite sure where to look... thanks!! Rob Klingsten

[Dovecot] Dovecot ignoring Quotas
by Frank Doege 03 Mar '07

03 Mar '07

Hi, i have installed the dovecot 1.0rc25 and everything is working well. I have connected it to a postgresql database. Now to my little problem: Postfix is delivering into a maildir folder with active maildirquota patches, and this is working well. The problem is only that dovecot is not recognizing the maildirquota file at all. I have configured it as in the documentation with Plugin { Quota=maildir } Anyone any idea ? maybe this is a bug ? Thanks

[Dovecot] Using auth_bind_userdn causes uid to be improper case
by Aaron Luchko 03 Mar '07

03 Mar '07

I'm having a problem with dovecot-1.0-1.1.rc15.fc6 + LDAP + auth_bind_userdb. I have the following /etc/dovecot.conf: mail_location = maildir:/var/spool/mail/%u/ protocols = imap pop3 mail_log_prefix = "%Us(%u):%i:%h " first_valid_uid = 5001 first_valid_gid = 5001 protocol imap { } protocol pop3 { } protocol lda { postmaster_address = postmaster(a)example.com } auth_verbose = yes auth_debug = yes auth default { mechanisms = plain userdb ldap { args = /etc/dovecot-ldap.conf } passdb ldap { args = /etc/dovecot-ldap.conf } user = root } dict { } plugin { } and /etc/dovecot-ldap.conf: hosts = driveable.example.com base = dc=example,dc=com #dn = cn=Directory Manager #dnpass = password auth_bind_userdn = uid=%u, ou=People, dc=example, dc=com uris = ldap://127.0.0.1 user_attrs = mail user_filter = uid=%u user_global_uid = 5001 user_global_gid = 5001 pass_filter = uid=%u The problem is that if we have an entry in LDAP, User Name, with the uid UName, postfix stores the users mail in /var/spool/mail/UName If I log into dovecot using uname (LDAP uid isn't case sensitive) than dovecot tries to look in /var/spool/mail/uname, similarly if I log in with unAME dovecot will look in /var/spool/unAME. However, if instead of using auth_bind_userdn = uid=%u, ou=People, dc=example, dc=com I bind with dn = cn=Directory Manager dnpass = password than it correctly looks in /var/spool/UName regardless of the case used when logging in. It seems like when I log in with auth_bind_userdn %u is being left as the value I logged in with rather than being reloaded from LDAP. I was wondering if I have made some mistake in the configuration files to cause this behaviour or if something else is going on? thanks, Aaron

[Dovecot] automaticly move expunded emails to trash Folder
by Wilfried BARNAVON (Perso) 03 Mar '07

03 Mar '07

Hi I try to migrate from courier to Dovecot. Is there a way to get the same behaviour of Courier-imap with dovecot, about expunged emails ? I though about using the Lazy-Expunge plugin. The problem with this plugin is the following: messages are moved and set to be deleted in the Trash Folder. I would like they weren't set to be deleted. Is there a way to mitigate the behaviour of this plugin, or is there another plugin having this task in charge ? Thanks Wilfried BARNAVON

[Dovecot] Struggle with Postfix/Dovecot-auth and SASL
by Ingo Reimann 03 Mar '07

03 Mar '07

Hi List, I just updated an old sendmail installation to a modern postfix/dovecot system with mysql backend. Everything works fine but SMTP-AUTH fails with some clients. The problem is, that with PLAIN (old) clients send the base64 coded form: USERNAME\0USERNAME\0PASSWORD which, as i understand dovecot interprets as MASTERUSER\0USERNAME\PASSWORD. New clients send \0USERNAME\0PASSWORD which works fine. I don`t like to use masterusers, because then everyone would be able to log in as someone else. When i don`t have a passdb with master=yes in my dovecot.conf, Dovecot complains auth(default): passdb(XXXX(a)YYY.TLD,master): Attempted master login with no master passdbs If i create a passdb with contains everyone, everyone may look into other mailboxes. No good idea. I can`t change the old clients, but for now, i don`t know, what i am doing wrong or how to correct it. No real HowTo for my setup on the net, it seems that everyone uses cyrus-sasl. May anybody help, because i don`t like to switch my setup or use 2 auth daemons. My System: Debian Etch, postfix (2.3.7-3), dovecot (1.0.rc15-2) Best wishes, Ingo Reimann System Manager -------------------------------------------------------------------- ICSmedia GmbH in Münster: Soester Straße 13, 48155 Münster in Dortmund: Mönchenwordt 5, 44137 Dortmund im Internet: http://www.icsmedia.de Telefon: (0251) 60 60-403 Telefax: (0251) 60 60-190 E-Mail: ingo.reimann(a)icsmedia.de -------------------------------------------------------------------- Geschäftsführung: Frank Wulf Sitz der Gesellschaft: Münster Amtsgericht: Münster HRB: 46 97

[Dovecot] Stopping certain users from using IMAP, or POP3, etc.
by David Craigon 02 Mar '07

02 Mar '07

Hi there, I'm building a mail system for an ISP. We want to be able to turn on or off IMAP or POP3 access for certain customers- basically we want to be able to offer a customer POP3 access, unless they pay us some more money, in which case they get IMAP The username and password will remain the same, and are driven out of a postgres database. The best way I've though of doing this so far is by defining separate auth systems for IMAP and POP. Is this the best way? A gold star is available if you can think of a way that if they try and use IMAP but haven't paid for it it rejects them with "Give us all your money..." or some such.

Hi, I'm trying to write a plugin that need to do some %var-substitution. Is there a way to get the var_expand_table used by the process? If not, I guess I could use getenv("USER") (for %u, %n and %d) and getenv("HOME") (for %h); but what for the other ones? Cheers, Nicolas

[Dovecot] Deleting when Over Quota
by Daniel Watts 01 Mar '07

01 Mar '07

Hi All, I've read a bit about this but don't really see a full solution anywhere. Has anyone actually got a good fix for this? Telling a user they are over quota then not allowing them to delete anything does seem the height of perversion. =) Question is - is this even a problem for the IMAP server? Or should the MUA be detecting over quota problems and then issuing the right commands to delete messages WITHOUT the copy to Trash? Lastly - even if it is the MUA's responsibility - will Dovecot not still have a problem with indexes? I suspect perhaps not if: A. When using FS Quotas you store the indexes in a non quota partition B. When using other quotas (dirsize / maildir++), Dovecot does not count the index files when counting up the usage. Is B true? Best wishes, Daniel

[Dovecot] Still issues with new message count...
by Brian Taber 01 Mar '07

01 Mar '07

I am still having issues with new message count. When I move a message to another folder, it counts that message as new until you go into that folder. Is there a way I can solve this? Could it have something to do with NFS? I have tried all the NF workarounds with no luck... I have also tried NFSv3 and NFSv4, no difference. I store the indexes on the local drive...

[Dovecot] Event on Logout
by Luca Bertoncello 01 Mar '07

01 Mar '07

Hi, @all! Is it possible, with Dovecot, to do something (eg: an SQL-Query) when the User logs out (POP3) or do some action (IMAP)? My problem is to notify a DB when the user logs out or delete E-Mail (in this case, just for IMAP). Thanks for your answer! P.S.: if it is NOT possible, it is my Hit for the next version! :) -- _______________________________ Luca Bertoncello -Programmierung / Mailserver- IMS Internet-Media-Service GmbH Bayrische Str. 18 01069 Dresden Geschäftsführer: Axel C.E.

[Dovecot] How to Prevent IMAP Folders being moved, deleted or renamed
by FreeStyle 01 Mar '07

01 Mar '07

Hello I use exim/dovecot combination for mail delivery and pickup and I'm wondering how I can prevent users from moving, deleting or renaming particular IMAP folders. I use the MailDir mailbox format. The reason for doing this is that I have some special exim filters which deliver mail to specified directories. I don't want users to be able to change these folders because it will mess up the filtering. Also my mail client (Thunderbird) doesn't check the filter folders automatically is there an option in dovecot that lets you send notification to clients when new messages arrive in certain folders. more info: http://kb.mozillazine.org/How_do_I_check_for_new_messages_in_other_folders

[Dovecot] segv when Mailbox is in inconsistent state, please relogin.
by Steffen Kaiser 01 Mar '07

01 Mar '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, for testing I have different filesystems on various block devices, which I mount on /mnt/mailcache as needed; however, the indexes and caches are located on /var/cache, hence, they get out of sync easily. No offense. Hoever, the web page (http://dovecot.org/bugreport.html) states that every signal 11 is a bug and will be fixed, so here it goes: running Linux x32, Debian Etch, Dovecot rc23, MUA: Thunderbird. It occurs to me that the data on /var/cache must be younger than the one on /mnt/mailcache; e.g. when you re-login after the segv, it works fine. There seems to be one segv per folder with messages.

We're exploring the use of "plus addressing" in our MTA (Exim), which delivers "user+topic(a)domain.com" to a user's "topic" folder. However, the case-sensitive nature of our ext3 filesystem means that a message destined to "topic" won't deliver to a user's "Topic" folder. For example, if a user creates a "Topic" folder, and gives "user+Topic(a)domain.com" to a web form that lower-cases it, delivery is deferred. Although we're checking to see if Exim can workaround this, is there a way Dovecot (1.0rc24) can force lowercase folder names without a patch? We'd hate to do this but are exploring our options. Thanks! Rich
