[Dovecot] ssl + dovecot + debian sid
by Novák Áron 16 Oct '05

16 Oct '05

Hi! On the unstable version of Debian I try to use Dovecot POP3-ssl server. I both tried out the debian package(1.0.alpha3-2.0.1) from the official repository and compiling from source(1.0 alpha3 version). The error is always the same: Oct 15 09:28:04 www dovecot: pop3-login: Can't set cipher list to 'all:! LOW': error:25066067:DSO support routines:DLFCN_LOAD:could not load the shared library Is it a bug of dovecot or a bug of the openssl package? My relevant libssl packages: Package: libssl0.9.8 State: installed Version: 0.9.8-3 ------- Package: libssl0.9.7 State: installed Version: 0.9.7g-5 Thanks: Aron Novak

[Dovecot] a few questions about my experience with alpha1
by Glenn Leavell 16 Oct '05

16 Oct '05

Hi all, I've just switched from 0.99.10.6 to alpha1 on a Solaris 9 system, and I have a few questions: 1) I'm using "verbose_proctitle = yes" but I don't see the special username or IP address information in the output of ps. I've used: ps -fu dovecot ps -ef | grep dovecot /usr/ucb/ps aux | grep dovecot The process table simply shows the /usr/local/sbin/dovecot, dovecot-auth, and imap-login processes. Is there something else that I need to do, or is there a special way that I should use ps? 2) After sending dovecot a HUP signal, the logs will report something like: Warning: SIGHUP received - reloading configuration And everything seems to work fine. However, *sometimes* after sending a HUP signal, logging will stop indefinitely. Has anyone else noticed anything similar? 3) We use UW in production, and I'm new to any real use of namespaces. Almost all of our clients use the root "~/Mail/" to find their folders (in $HOME/Mail/) and their INBOXes are located in $HOME/.inbox. A few people actually find their folders with the direct path Mail/foldername. So, I'm trying to configure Dovecot to work with any of these roots / prefixes: ~/Mail/ Mail/ "" (empty/blank) I'm using the namespace configuration below, and it seems to work with any of the above prefixes. However, the logging that I see makes me wonder if I'm doing it the best way. Note the attached log file. All of this output was generated with this single IMAP command: A01 LOGIN bozo mypassword Here's my configuration: **************************************************************************** # Default namespace private { separator = / prefix = location = mbox:%h/Mail/:INBOX=%h/.inbox:INDEX=%h/Mail/ inbox = yes hidden = no } # This is the standard ~/Mail/ namespace that our clients tend to use namespace private { separator = / prefix = ~/Mail/ location = mbox:%h/Mail/ hidden = yes } # This namespace is for a few folks who might actually try to # directly access "Mail/foldername" -- as if they were accessing a real # filesystem path. namespace private { separator = / prefix = Mail/ location = mbox:%h/Mail/ hidden = yes } **************************************************************************** So, is this the best way to configure the namespaces for what I'm trying to accomplish? And any pointers on how to interpret what Dovecot is working through with regard to the attached logs would be appreciated. Notice the "Sending log messages too fast, throttling.." message (again, generated from that single login command). What might be causing that? By the way, is there any real difference between the use of %h/Mail and the possible use of ~/Mail in the location fields above?

[Dovecot] Problem with pop3 and alpha3
by aspar＠unisa.it 16 Oct '05

16 Oct '05

Hi all, I have a problem with dovecot-alpha3 and pop3 protocol (on a tru64 5.1a...) In my Maildir/cur there are 8144 mails and if I use pop3 protocol I receive in the output 8146 line instead of 8144. The problem is that 2 mails are duplicated . The output of List command is like: 1 51265 2 261783 . . . 2987 30291 2987 30291 (duplicated line) 2988 16631 . 4601 1231 4602 8921 4602 8921 (Another duplicated line) 4603 1313 I've deleted dovecot.* and dovecot-uidlist in the Maildir path but the problem remains. Suggest? Is a bug? I've tried also to remove the first 1000 messages but the problem now is on the mail number 2635 and not 1987 like I can think.

[Dovecot] Possible bug: why is the owner of home-directory important?
by Qweb - Yavuz Aydin 16 Oct '05

16 Oct '05

Dear all, I am trying to migrate one of our systems to dovecot. We were using uw-imapd in black-box-mode before. Since the home-directory of a user is not unique per definition on our systems, we have kind of a different setup. As an example: I got a user, let's say user1. It's home directory is /local/web/websites/5850844095/www. This directory has the following permissions: # ls -la /local/web/websites/5850844095/|grep www drwxr-x--- 7 www-data g5850844095 4096 Oct 13 12:28 www (user1 is member of the group g5850844095) Why is logging in not working properly? See: # telnet localhost 143 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK dovecot ready. 1 LOGIN user1 password 1 OK Logged in. Connection closed by foreign host. And in the logfile I see: Oct 13 13:09:47 s1 dovecot: chdir(/local/web/websites/5850844095/www) failed with uid 1020: Permission denied Oct 13 13:09:47 s1 dovecot: child 1527 (imap) returned error 89 However, when I change the permissions on the home-dir to 755, it works. The point is, none of my mailboxes (INBOX or others) are in my home-dir, so why does dovecot need my home-directory? I hope someone can help. PS1 the default_mail_env reads: default_mail_env = mbox:/local/mail/imap/%u/:INBOX=/local/mail/spool/%u PS2 This is on a Debian Sarge (3.1) system. -- Best regards, Yavuz Aydin Qweb Internet Services

[Dovecot] Cyrus migration - Header version 6 not supported
by Arnaud Limbourg 16 Oct '05

16 Oct '05

Hello, I was previously running a cyrus server which I realized later on is overkill for what my needs so I would like to switch to dovecot. Unfortunately the cyrus2courier utility to migrate the mails gives me the error Header version 6 not supported I was using cyrus 2.2.3. Does anybody have any advice on how I could migrate all the mails ? Thank you. Arnaud.

[Dovecot] Need help with SQL queries after updating to 1.0a3
by Jonathan Vanasco 16 Oct '05

16 Oct '05

I upgraded to 1.0a3 - i have everything in the config migrated over, but I'm unsure about the way i should be querying postgres my db handles virtual accounts only, and is set as such: CREATE TABLE accounts ( local_part VARCHAR(64) NOT NULL, domain VARCHAR(64) NOT NULL, password VARCHAR(64) NULL, home_dir VARCHAR(256) NOT NULL, uid INTEGER DEFAULT '1003', gid INTEGER DEFAULT '1003', active CHAR(1) DEFAULT 'Y' ); so an entry would be something like: user | domain.com | md5('passwprd') | /path/to/maildir/ | 1003 | 1003 | Y I've rewritten the password query as such: password_query = SELECT local_part || '@' || domain as user, password FROM accounts WHERE local_part = '%n' AND domain = '%d' AND active = 'Y' ; but i can't get things to work with the user query user_query = SELECT home_dir AS home, uid, gid FROM accounts WHERE local_part = '%n' AND domain = '%d' ; can anyone point me in the right direction? the docs in the distribution aren't very clear, and the wiki seems to have more .9 info than 1.0 info this is what i've gotten of of auth_debug: Oct 11 11:53:37 rsrr1 dovecot: auth(default): client in: AUTH 1 PLAIN service=IMAP secured lip=66.250.131.114 rip=209.73.1.130 resp=xxxxxxxxxxxxxx Oct 11 11:53:37 rsrr1 dovecot: auth(default): sql(test(a)mydomain.com, 209.73.1.130): query: SELECT local_part || '@' || domain as user, password FROM accounts WHERE local_part = 'test' AND domain = 'mydomain.com' AND active = 'Y' ; Oct 11 11:53:37 rsrr1 dovecot: auth(default): client out: OK 1 user=test@ mydomain.com Oct 11 11:53:37 rsrr1 dovecot: auth(default): master in: REQUEST 26 93326 1 Oct 11 11:53:37 rsrr1 dovecot: auth(default): passdb(test@ mydomain.com,209.73.1.130): passdb didn't return userdb entries Oct 11 11:53:37 rsrr1 dovecot: auth(default): userdb(test@ mydomain.com,209.73.1.130): user not found from userdb Oct 11 11:53:37 rsrr1 dovecot: auth(default): master out: NOTFOUND 26 Oct 11 11:53:37 rsrr1 dovecot: imap-login: Internal login failure: user=<test@ mydomain.com>, method=PLAIN, rip=209.73.1.130, lip=66.250.131.114, TLS

[Dovecot] Cannot see new messages in Inbox
by Mark Farmer 16 Oct '05

16 Oct '05

Hi, just wondering if anyone has any suggestions on this. I'm having a rather odd problem in that I cannot see new emails in my IMAP inbox, this is true for both Thunderbird & Squirrelmail. I know the mails are arriving & being delivered correctly as I see the logs for postfix & procmail, and I can also list them from a command prompt on the Linux mail server. The really odd thing is that I can see new mail in other folders within the same mailbox (maildir) without issue, it's only the inbox that seems to be exhibiting the problem. Nothing has changed on the server and all permissions look fine. The only thing I can think of is that I reinstalled my other machine with Linux the other day & setup Thunderbird as normal - I didn't have any problem at the time but yesterday I noticed the problem. I have tried stopping & restarting the dovecot service a few times but this hasn't helped. I've had this running for months now & this just seems to have cropped up, very strange. Any thoughts anyone? farmorg

[Dovecot] How to set up a passwd file for virtual hosting
by Richard Freeman 16 Oct '05

16 Oct '05

Hi, Exim4 is running fine and I am trying to set up Dovecot 0.99 to handle virtual users (http://wiki.dovecot.org/moin.cgi/VirtualhostingWithExim) so I don't have to set up user accounts for each e-mail address I want to server out via pop3. I need to create a user and passd file, a bit like /etc/passwd, but in a different location for my dovecot virtual users. I can create a blank file such as /etc/dovecot/users (beware my increasing vi skills...) but how do I add users and passwords to this? Can I just type them in and separate them with colons? If so, how would I add a password to the file? I am happy using the passwd command which alters my user passwords in /etc/passwd. Can I use it or something similar to create the passwords for the users in my new file /etc/dovecot/users ? Is there any way I can use an MD5 hash or CRYPT format for the passwords? Yours, Richard

[Dovecot] FreeBSD Ports Issues
by Barry Jeung 16 Oct '05

16 Oct '05

Installed dovecot for the first time, using the FreeBSD port. Found 2 issues with the port, and I've only been able to resolve one of them. First of all, the port, (or perhaps dovecot) does work with mysql 4.1 encryption. I had to create a user with access to the mysql table, then do 'set password = old_password('password');' in order to get dovecot to talk to the server. The second issue, is that dovecot seems to be ignoring my user_query settings. I have the following in dovecot-sql.conf: password_query = SELECT password FROM mailbox WHERE username = '%u' user_query = SELECT maildir, 125 as uid, 125 as gid FROM mailbox WHERE username = '%u' The password query works, however the user query seems to default to something else, and no matter how I change the user_query line in dovecot-sql.conf, it uses the same query. Here's an excerpt from my logs: dovecot: Oct 11 03:19:30 Info: Dovecot v1.0.alpha3 starting up dovecot: Oct 11 03:19:31 Info: auth-worker(default): mysql: Connected to (null) (postfix) dovecot: Oct 11 03:19:35 Info: auth-worker(default): sql(user(a)example.com,1.2.3.4): query: SELECT password FROM mailbox WHERE username = 'user(a)example.com' dovecot: Oct 11 03:19:35 Info: auth(default): client in: AUTH 1 PLAIN service=IMAP secured lip=5.6.7.8 rip=1.2.3.4 resp=AGJqZXVuZ0Bjb2JhbHQtaXQuY29tAHRlc3Q= dovecot: Oct 11 03:19:35 Info: auth(default): client out: OK 1 user=user(a)example.com dovecot: Oct 11 03:19:35 Info: auth(default): master in: REQUEST 1 13590 1 dovecot: Oct 11 03:19:35 Info: auth-worker(default): sql(user(a)example.com,1.2.3.4): SELECT home, uid, gid FROM users WHERE userid = 'user(a)example.com' dovecot: Oct 11 03:19:35 Error: auth-worker(default): sql(user(a)example.com,1.2.3.4): User query failed: Table 'postfix.users' doesn't exist dovecot: Oct 11 03:19:35 Info: imap-login: Internal login failure: user=<user(a)example.com>, method=PLAIN, rip=67.188.145.230, lip=209.25.157.150, TLS So obviously the query fails because that table doesn't exist. However that's not the query that I have in the configuration file. As a matter of fact, I have no idea where it's pulling that query from. Any pointers would be greatly appreciated.

[Dovecot] Dovecot on FC3 with Active Directory authentication
by Jeff Ramsey 16 Oct '05

16 Oct '05

I am building an IMAP server that uses Dovecot/Sendmail on FC3 to replace our POP server that uses Dovecot (via POP)/Sendmail on FC2. My new server is authenticating users via winbind/smb against my WIndows 2003 Active Directory. The authentication is working great. The problem come up when a user gets an email and has not ever logged into the IMAP server via SSH, local, or GDM, therefore that user has no home directory. /etc/pam.d/ssh, /etc/pam.d/login, and /etc/pam.d/gdm all have a line calling mkhomedir.so, which is using the /etc/skel home directory skeleton to create the user's home dir upon successful login, however, when I add that line to /etc/pam.d/dovecot, I get a permission denied error in /var/log/maillog. I'm assuming this is because dovecot is running as the user at this point, and therefore does not have the necessary permissions to create a folder under / home/DOMAIN/, which is where the home dir is supposed to be. If I manually create the folder, and set it's permissions, or if the user logs in via any of the before-mentioned methods, dovecot and sendmail work great. Does anyone else run a similar setup? If so, how did you overcome this problem? If not, can some Linux gurus recommend either altering the write permissions on the /home/DOMAIN directory, or should I try to call the mkhomdir app earlier in the process somehow? Any help would be appreciated. I'm trying to make this as seamless as possible. Basically, I can manually create all the home dirs well enough, but when I add a new user to the Active Directory, it would be nice if this part was automated as much as possible. Thanks, Jeff Ramsey MIS Administrator Tubafor Mill, Inc.

[Dovecot] Mapping username only for auth
by Andy Cravens 16 Oct '05

16 Oct '05

I am running Dovecot alpha 3 with authentication from the local shadow file. I'd like to change the authentication to use our radius server. I can probably do this through pam. The usernames on the mail server are set up as first initial + last name ( jdoe for John Doe ). The usernames on the radius server are the employee number. Is there a way to map the username to the employee number in dovecot before handing off the authentication to the radius server? I want the usernames on the mail server to remain first initial + last name. I don't mind maintaining a mapping file to go from username to employee number because I can automate this task. Has anybody done this?

[Dovecot] saslauthd/dovecot/root
by Andrew Instone-Cowie 16 Oct '05

16 Oct '05

Hi, I am using SMTP-AUTH over TLS with sendmail, to allow remote users to authenticate and send mail via my server, and this uses saslauthd to authenticate users. I have set up saslauthd with the "MECH=rimap" mechanism, so it uses the local IMAP server, Dovecot, for authentication. I want to do this because Dovecot is set up to use /etc/passwd for user credentials (so I don't have multiple password files to manage), and Dovecot handles restricting the range of valid UIDs (including blocking root). (Using the default MECH=shadow with saslauthd allows all users to authenticate, which I don't want) For real "normal" users, this all works fine - right password = user can relay mail, wrong password = relaying denied. So far so good. If I try to authenticate as root (which I want NEVER to work), with the wrong password, Dovecot correctly refuses to allow root IMAP access and saslauthd/sendmail denies the relay. But if I try to authenticate as root with the correct password (which I still want NOT to work!), Dovecot still refuses IMAP access, and puts this in the maillog: Oct 5 14:16:18 hadrian dovecot: Logins with UID 0 not permitted (user root) Oct 5 14:16:18 hadrian imap-login: Internal login failure: root [127.0.0.1] But saslauthd seems to treat this as a successful authentication and still allows root to relay email! So: Dovecot problem or saslauthd problem? Server is running CentOS 4.1, fully patched. Packages are dovecot-0.99.11-2.EL4.1, cyrus-sasl-2.1.19-5.EL4, sendmail-8.13.1-2. Thanks Andrew

[Dovecot] Dovecot pop3 locking up
by Neil Wilson 16 Oct '05

16 Oct '05

Hi guys and girls, I am having a problem with Dovecot. It seems like it's the dovecot auth daemon that is locking up(I'm guessing) I am running SuSe 9.3 Pro, and Dovecot 0.99.14 Everything works perfectly for a few days, and then eventually I end up with tons of what look to be "stale" processes.(I'm guessing roughly 300 like below.) 4204 ? S 0:00 dovecot-auth 24722 ? S 0:00 pop3-login 24723 ? S 0:00 pop3-login 24724 ? S 0:00 dovecot-auth 24921 ? S 0:00 dovecot-auth When I "telnet 127.0.0.1 110" I get a login, and I can type "User blabla" I get an "OK" then I type in "pass blabla" and then I don't get any response, and I have to kill my session with "Ctrl ]" and then "quit". I am using both POP3 and IMAP, but it seems to be only the POP3 daemon that dies. There are roughly 60 users on the network, and it dies after roughly 5 days of usage, and I then have to restart Dovecot by running /etc/init.d/dovecot stop and then start Any help would be appreciated. Thanks. -- Neil Wilson

[Dovecot] new to dovecot
by John O'Loughlin 15 Oct '05

15 Oct '05

Hello all I'm new to dovecot (and imap in general!) having installed only only today. My current set up is exim as MTA with procmail delivering /var/spool/mail/%user (which gets nfs exported). We also have a pop3 server running as well. I'm moving to new machine and though I'd look at dovecot and squirrelmail. In /etc/dovecot.conf I'm confused by the default_mail_env, what exactly are we trying to set here? We have $MAIL set already, so for example what does the line: default_mail_env = mbox:~/mail/:INBOX=/var/mail/%u try to set Cheers John

[Dovecot] Same email recieved
by Bob Hope 14 Oct '05

14 Oct '05

Some of my users seem to be receiving the same e-mail over and over. This doesn't happen all the time, just once in a while it seems to get stuck in a loop. Is it possible that dovecot is the culprit here or is this a problem with something else? I'm running Postfix/amavisd/dovecot on Slackware 10.1. Regards, Savage

Timo, A rare assert and core dump out of 1.0alpha3. My setup: Solaris 9, mbox format, using imap only. Built dovecot with gcc 4.0.1.

[Dovecot] Message not
by Andrew Hutchings 13 Oct '05

13 Oct '05

Hi, I'm sure this is a bug fixed in CVS or something stupid I did in the config but here goes: I am getting at least one complaint a day about POP login customers getting 'Message not found' errors while getting their mail. The only thing I can find in the messages that could be related is: Oct 12 15:40:18 svr21 dovecot: pop3(user): Mailbox init failed top=0/0, retr=0/ del=0/0, size=0 It doesn't happen on a very high percentage of logins which makes me think its a locking problem of some kind. Any ideas?

[Dovecot] dovecot won't launch
by Chad Cunningham 12 Oct '05

12 Oct '05

Hi, I downloaded the latest dovecot (1.0 alpha 3) and tried numerous installs which get me nothing. No errors, no crashes, no segfaults and no running dovecot. It just seems to silently exit. I was trying to build with mysql support but I've also tried a plain old install, just configure, make install, etc. I get nada. strace doesn't show anything, at least as far as I can tell. No messages are logged. No output to the console. Any ideas? My only guess, no idea if it matters, is that dovecot doesn't like the fact that this is a VPS (User Mode Linux, Fedora Core 3). But I don't see any reason why not, other mail servers are pretty happy... Here's the strace: -bash-3.00# strace dovecot execve("/usr/local/sbin/dovecot", ["dovecot"], [/* 17 vars */]) = 0 uname({sys="Linux", node="monkey", ...}) = 0 set_tid_address(0) = -1 ENOSYS (Function

Hi All, I'm currently doing nightly full backups of /home. I'm not sure if a full back up is the best way to do backups. I know with my fileserver i do weekly full backup and daily incremental which would file on those type of files.

Ok, so if anyone runs into a problem where dovecot reports chdir(/home/BLAH) failed with uid NNN: Permission denied in Fedora Core 4 or otherwise, it seems to be a SELinux problem. Turn OFF SELinux and the problem goes away.

[Dovecot] time out error and email with attachments
by Roberto Cipollini 09 Oct '05

09 Oct '05

I'm facing some problem with emails and attachments. I'm not sure it's dealing with MTU (it is set to the maximum number before a fragmentation occurs). I have no errors from pop3, but the following message is the best I can show you just to understand my problem. The log shows this: "imap(roberto.cipollini(a)allmediasolution.com): Oct 04 17:35:03 Error: Timeout while waiting for release of exclusive fcntl() lock for index file /mail/allmediasolution.com/roberto.cipollini/.INBOX/.imap.index " I think that the pop3 process is locking the index file (thunderbird was waiting to download the file) and the imap (i tried to get the file from webmail) is going time out. Can anyone tell me how to fix the time out? any suggestion? do you need more information/logs? can I try different setting in dovecot conf? thanks for any kind of help. Roberto

[Dovecot] chdir failed: Permission denied
by Joe Sislow 09 Oct '05

09 Oct '05

Hi there, Upgrading to Fedora Core 4 from an old server running Red Hat 7.3. I'm moving accounts over by hand, and I'm having the following error crop up for *everyone*. chdir(/home/BLAH) failed with uid 500: Permission denied Now, that UID is correct, the user has that access, and there are no permissions problems changing to that directory. I've got the mail in /var/mail/XXX for each user as a simple mbox. I was browsing through the code to check for what *exactly* dovecot is doing when it's trying to change directory there. The error reporting is a bit spotty. It could be that it can't change to that directory (unlikely). It could be that something in that path is a problem (also unlikely, as the /home directory is world readable and executable), or, it could have something to do with a file or directory it's trying to create. I'm not sure. Could someone let me in on what files or directories that dovecot tries to create by default? This permission denied error doesn't make any sense (I created a brand new user with nothing there, made all of his directories readable/writeable, and executable by EVERYONE, and it STILL gives me this error.

[Dovecot] Dovecot Setup as just a local IMAP server.
by David Terei 06 Oct '05

06 Oct '05

Hey All, Id just like to start by thanking Timo Sirainen and any others that helped produce such a great IMAP server, it was a breeze to set up with no previous experience in mail servers. What I am trying to do is setup a spare computer to run Dovecot and that It stores all my email from my accounts which are all accessed through POP. This way instead of being tied to one mail client (and hence OS and Computer) I just set up my mail client to access Dovecot and then I'm done. So I am trying to set up an IMAP server to store my emails instead of just storing them on my local hard disk really. Now so far Ive set up Dovecot and Its working fine, but How would I get my email accounts mail to be placed in the Inbox of my IMAP account? I'm think I would need to use either fetchmail or getmail to grab my mail. After that do these programs just save it in the appropriate IMAP folder on disk (which would be new?) or do I need a MTA such as qmail setup and fetchmail or getmail passes the email to the MTA which just transfers it locally on the same computer? So any help would be greatly appreciated as well as advice on which software to use, the getmail site attacks fetchmail quite strongly, but I'm not sure of its performance being written in Python as I'm running on an old Pentium MMX(100MHz) using OpenBSD 3.7. Sorry for the long email I never can seem to keep them short :) Cheers, David Terei

[Dovecot] extra characters after mailbox names
by Paul 06 Oct '05

06 Oct '05

After installing alpha3, when I view a list of my IMAP mailboxes in Pine 4.64 on Linux, several of the mailbox names are followed by odd characters: ., ~, and _. So the list of mailboxes looks like: INBOX saved_ sent-mail~ Biz Service. Home_ and so forth. The distribution of the characters remains the same throughout the Pine session, but is different every time I restart Pine. It doesn't happen in Pine 4.63 or any other client, but I associate it with Dovecot rather than Pine because it started exactly when I upgraded Dovecot today, rather than five days ago when I upgraded Pine.

[Dovecot] I need to enable percent hack in dovecot logins

I am using dovecot with vpopmail and qmail and problems is percent hack that works with qmail-pop3d does not work with dovecot. So login works like that: firstname.lastname%domain.ext I need that function to work with dovecot too, and I am using stable 0.99.x series of dovecot. Problem is that some Apple machines client can't use at-symbol in their login names. So, where I need to hack sources to convert % -> @ to get login working.

[Dovecot] Changing pop3_uidl_format
by Jeff Simmons 05 Oct '05

05 Oct '05

I recently set up an OpenBSD - Dovecot mail server for a client. Naturally (according to Murphy's Law) they want to use Outlook 2003, pop3s, and leave messages on the server. And just as naturally, the UIDLs don't seem to be working, and when they download mail, they get EVERY email stored on the server, not just the new ones. Other than switching them over to IMAP, I found the following in the Wiki documentation: #POP3 UIDL format to use. You can use following variables: # %v - Mailbox UIDVALIDITY # %u - Mail UID # %m - MD5 sum of the mailbox headers in hex (mbox only) # %f - filename (maildir only) #If you want UIDL compatibility with other POP3 servers, use: # UW's ipop3d : %08Xv%08Xu # Courier version 0 : %f # Courier version 1 : %u # Courier version 2 : %v-%u # Cyrus (<= 2.1.3) : %u # Cyrus (>= 2.1.4) : %v.%u #Note that Outlook 2003 seems to have problems with %v.%u format which is #Dovecot's default, so if you're building a new server it would be a good #idea to change this. %08Xu%08Xv should be pretty fail-safe. pop3_uidl_format = %v.%u So my question is, what happens if I just change pop3_uidl_format to %08Xu%08Xv and restart the server? Will it just change things over to the way I want them, or will it blow up all the existing mail already being stored there? Inquiring minds want to know. Thanks for any help you can provide. -- Jeff Simmons jsimmons(a)goblin.punk.net Simmons Consulting - Network Engineering, Administration, Security "It was on fire when I got here."

[Dovecot] using local-part delimiters in LDA delivery?
by OpenMacNews 03 Oct '05

03 Oct '05

hi all, i've exim 4.53RC2 + dovecot-cvs on OSX 10.4.2. i'm working on implementing recipient-delimiters for delivery from exim to a user's imap store using dovecot's cvs-lda. reading on the wiki (Jakob's latest comments?): " ... the part after the delimiter is passed to the lda as an additional parameter. so dovecot-lda should handle that parameter and leave the separator handling to the MTA. The MTA has to handle it anyway." it looks likes it's possible ... with appropriate changes in exim to my router: dovecot_localuser: driver = accept domains = +local_domains local_part_suffix = +* local_part_suffix_optional transport = dovecot_lda and transport: dovecot_lda: driver = pipe command = /.../deliver \ -c /.../dovecot-deliver.conf \ -d $local_part@$domain message_prefix = "" message_suffix = "" delivery_date_add envelope_to_add return_path_add log_output user = MY_MAIL_USER i'd like to be able to build delivery conditions in dovecot so that, e.g. mail to: bob(a)mydomain.com is delivered to "bob"'s default INBOX. but, mail to: bob+spam(a)mydomain.com is delivered to any specified (either a server-wide common relative path, or a user-specified) SUBFOLDER, say "bob/INBOX/.../.../spam_to_look_at" defined by a dovecot-rule invoked by the delimiter "spam" ... this is a little different than the approach Mark mentioned of delivering directly to folder_name specified by the local-part-after-delimiter ... questions: (1) until the two conf files merge, i'm guessing there needs to be some conditional logic in dovecot-deliver.conf rather than in dovecot.conf. correct? or should i be thinking SIEVE rules? (2) exactly WHAT "additional part" do i grab in dovecot? thx! richard

[Dovecot] Using procmail with virtual users...
by Arnaud Guiton 01 Oct '05

01 Oct '05

Hello all, I've a working dovecot installation on my machine, using exim3, virtual users and maildirs. I would like to add procmailrc rules for these (virtual) users, but i've not succeeded with that. The authentication is done with a passwd-file looking like this : testuser:password:uid:gid::/home/mail/testuser::chroot:maildir:/home/mail/testuser/Maildir/ i've put .procmailrc files in /home/mail/testuser/.procmailrc, but it this not taken into account, because the MTA never calls the procmail router as it resides after the dovecot one. How is the proper way of using procmail with virtual user (and is it at least possible) ? Thanks, -- Arnaud

[Dovecot] Red Hat ES 4 - dovecot-auth: Unknown password scheme SMD5
by mel llaguno 01 Oct '05

01 Oct '05

I have a couple of questions regarding the default dovecot packaged with RedHat ES 4. The dovecot version is 0.99.11-2.EL4.1 which I assume is considerably behind the current stable version of 0.99.14. Is it the fact that I am using an older version of dovecot that SSHA passwords in an openldap directory are not recognized and give the following error: dovecot-auth: Unknown password scheme SMD5 ? LDAP is working as expected for NFS maildirs. I have dovecot 0.99.13 working on fedora core 3, but the stability of fedora leaves much to be desired and would like to get a stable, low maintenance install of dovecot on an enterprise supported linux. Redhat does not have packages for 0.99.14 and I would rather compile from source if possible. I've specified --with-ldap as part of the configure script, but am wondering if there is anything more to add to support SSHA passwords. Until dovecot 1.0 is proven in the field, it is not a consideration for the production environment this server is being used for. Any help with this matter would be greatly appreciated. TIA, Mel Llaguno

[Dovecot] Can't connect to auth server at default: Connection refused
by Chris Wakelin 30 Sep '05

30 Sep '05

We've being running with Dovecot 1.0-stable since Tuesday, and on the whole it's gone very well (meaning nobody's noticed!). My best estimate is we're using half the disk accesses and 2/3 the CPU of UW-IMAP/Qpopper. We've quite a mixture of error messages in the logs, the most worrying of which is that several times we've had a few seconds of "xxx-login: Can't connect to auth server at default: Connection refused" (where xxx is pop or imap). It seems to sort itself out shortly afterwards. We're using userdb=passwd, passdb=passwd (authenticating via NIS). From Tuesday we'll be using passdb=pam (pam_ldap to Active Directory). My first guess is that some dovecot-auth process stops responding and gets killed off. Is this right? Other errors we're seeing include 1) pread_full() failed with mbox file /export/mail/c/37/sau04djp/INBOX: No such file or directory (when there is!) 2) mbox sync: UID inserted in the middle of mailbox (especially with .prayer folders - configuration folders for our Webmail) 3) file mbox-lock.c: line 505 (mbox_lock): assertion failed: (lock_type == F_RDLCK || ibox->mbox_lock_type != F_RDLCK) presumably some of these are fixed in alpha2.

[Dovecot] redirect and sieve BUG
by List Subscriptions [Obfusc8.Org] 30 Sep '05

30 Sep '05

I've only just subscribed to the list, but in reading through the back-issues have come across a bug with dovecot-lda that was reported previously, and I can reproduce. Using dovecot-lda CVS with Revision 1.21 of deliver.c (as newer versions won't compile against 1.0-alpha3), with dovecot 1.0-alpha3 and postfix 2.1.5 Rredirects mangle some headers - the 'To:' header ends up as: To: undisclosed-recipients: ; And there is no subject header. Running sendmail from the cmdline with: sendmail -i -f '<>' -- destination at address.com <msgtext> as suggested to test by *Timo Sirainen *results in a correctly formatted message. The mail_send_forward function in mail-send.c looks sane from what I can see, but then I'm not a C coder... Any clues guys? Cheers, Pete

[Dovecot] Maildir and counting inodes
by Andy Cravens 30 Sep '05

30 Sep '05

I've been testing with alpha 3 and I am about ready to go production. I am switching from mbox to maildir and I'd like to know if there is a formula or rule of thumb for determining if your file system will have enough inodes to handle all the mail message files. I could write a script to look at each user's mbox files, count the number messages and calculate the average number of emails per user, then add a fudge factor for expected growth. However, I doubt anybody actually goes to this much trouble to plan ahead. Or do they? I'm running Solaris 9 and when I created the file system I just used the defaults. If I need to change anything, I'd rather do it before going production. Thanks for any info you can provide on this subject.

[Dovecot] ManageSIEVE services with Dovecot cvs-LDA?
by OpenMacNews 28 Sep '05

28 Sep '05

hi all, has anyone had any success in getting the current dovecot cvs-lda's implementation of CyrusSIEVE responding to a ManageSIEVE client? in particular, i'm hoping that one can use, e.g., Mulberry's Client- & Server-side sieve editor: <http://www.cyrusoft.com/sieve/sievescreens.html> if i telnet to my dovecot box's sieve port ( = 2000) i get no response at all ... telnet localhost 2000 Trying 127.0.0.1... telnet: connect to address 127.0.0.1: Connection refused telnet: Unable to connect to remote host net-stat shows nothing on port 2000, and, afaik, there's no mention of a server on the wiki ... so i'm either doing something wrong, or "it" is simply not there. has a sieve server been implemented? any plans? thx! richard

But I found that I must add the mail=mbox:/var/spool/virtual/%d/%n part. Without this part, the dovecot seems not checking the right location of mail spool and simply say that "no new email". Now I added this part together with "home=/tmp" part into userdb config and It works now with IMAP folder in /tmp directory. But I want to ask if there is any file locking problem as I am running virtual email with vmail as owner for all mbox accounts. And it seems that they are all share the same IMAP folder located in /tmp directory.

[Dovecot] Hostname passed to PAM as rhost
by Tom Alsberg 27 Sep '05

27 Sep '05

(I am sorry to bother the list with something I should have verified myself right now - I simply do not have access to the source code here) Thinking of some limit I wanted to put with authentication, I am wondering - when Dovecot authenticates a user using PAM, now that (in 1.0) it passes the rhost item to PAM, it passes a hostname, not an IP address. Does it double-verify the DNS record before it trusts this to be the hostname (first checking the IP address in in_addr.arpa and then checking that the hostname indeed maps back to the same IP address)? That is necessary in order to trust the client address when determining authentication strength in the PAM module based on the client location (specifically we want stronger authentication when the client comes outside of our network, while inside a plain password suffices), as else anybody could "spoof" the hostname by changing the IN PTR record of his IP address to point back to some "trusted" hostname (given he has control of the DNS zone his host is in, which is completely possible given the server knows nothing about it).

27 Sep '05

I've tried turning on mbox_very_dirty_syncs for myself (and a few other brave souls running 1.0-alpha3 rather than 1.0-stable) again to see what perfomance gain it gives (see thread http://www.dovecot.org/list/dovecot/2005-July/007956.html) Now we aren't running UW-IMAP at all, how safe is mbox_very_dirty_syncs assuming the only other process writing to mailboxes is our MTA (exim) which simply appends messages to the end? Is it safer still using Dovecot 1.0-alphas and the LDA? Does it matter if there are concurrent connections to the mailbox?

[Dovecot] new mailbox format v2
by Timo Sirainen 27 Sep '05

27 Sep '05

Updated version. The previous one was a bit too complicated with flag updates for pretty minimal benefits. Changes: - writing/reading mail flags can be disabled to get better performance without it requiring any changes to how the files are normally handled (so mixed more works fine). - writing flags now requires getting shared locks. so there's the overhead of locking but flag writers don't have to wait for each others. - reading requires no locking anymore. the comment in the previous version about reading only half a mail being a problem doesn't actually matter, since if a client tries to read an expunged mail Dovecot already disconnects the client immediately (since most clients can't handle such situation well anyway). - no more problems with mailbox readers locking out expungers - note about fcntl() locking being able to provide even higher concurrency - works just fine with plain dotlocks, so works fine with NFS And looks like I forgot to explain the "mail header padding" before. I'm not exactly sure if it's useful or not, but it doesn't hurt to have it there if it's wanted. The idea was anyway that if you're writing more than one flag at a time, having a 512 byte padding would make sure that when writing the few bytes the OS will only have to read one sector from disk (512 bytes in all todays OSes I believe?) to get the non-written parts of the sector instead of possibly reading two sectors. So it might help with trading disk reads for some wasted disk space. Generic ------- The point is to have a mailbox format where the mailbox can consist of one or more files. Grouping multiple files in a single file makes it faster to read, but it's slower to expunge mails from the beginning of the file. So this format would allow sysadmin to specify rules on how large the files would be allowed to grow. Index File ---------- Named "index". Index file gives a mapping between UIDs <-> filenames: Header: <uidvalidity> <last-used-uid> Record: <uid-first> <uid-last> <filename> Record: .. eg.: 1127468129 5 1 3 msg.1 4 4 msg.4 All of the UIDs don't have to actually exist in the file if they have been expunged. The record should be removed once all of the UIDs have been removed from it (and the file itself been deleted). The same file may appear multiple times in the index. For example: 1 2 msg.1 3 3 msg.3 4 5 msg.1 This means that UIDs 1, 2, 4 and 5 are in file msg.1, but UID 3 is in file msg.3. The filename doesn't matter as long as it's unique, but probably wouldn't hurt to include its first UID in the filename so humans can find mails more easily. The filename however must not end with ".lock". The file is modified by creating first exclusively owned "index.lock" file, updating it and then rename()ing it over the index file. This lock file shouldn't be held for a long time, so if it exists, and it doesn't get modified at all within 30 seconds, it can be overwritten. Before rename()ing over the index file, you should check with stat() that the index.lock file is still the same as you expect it to be (in case your process was temporarily stopped for over 30 secs). The index file's mtime timestamp must grow after each modification. This makes it easy to check if new mail has been added to the mailbox. Mail File --------- File header: Bytes Format Description 8 hex Header size 16 hex Append offset 4 hex Mail header size 4 hex Mail header padding 4 hex Keyword count in mail headers Mail header: Bytes Format Description 8 hex UID 16 hex Mail size 1 1/0 Answered flag 1 1/0 Flagged flag 1 1/0 Deleted flag 1 1/0 Seen flag 1 1/0 Draft flag 1 1/0 Expunged flag n 1/0 Keywords The file layout then goes: <File header> - possible padding due to Header size <Mail header #1> - possible padding due to Mail header size <Mail data #1> - possible padding due to Mail header padding (ie. next Mail header's offset is divisible with Mail header padding) <Mail header #2> etc.. The UIDs must be ascending within the file (but as said above, some UIDs between them may exist in other files). If mail has been marked with expunged-flag, it should be treated as if it was already expunged. The mail will really be expunged later in some nightly run. Reading the files requires no locking. If while reading you happen to hit unexpected end of file, it means that mails were expunged from the file. After that you'll look at the index file again to see which file the mail went and continue from there on. If the mail isn't found, it means it got expunged. Expunging happens by locking the file and then copying all non-expunged mails after the first expunged one to new file. Then update the index file with the new location for the UIDs, and at last ftruncate() at the position of first expunged mail in the original file. Flag updates require locking the file as well, otherwise we might try to write past the end of file when another process is expunging the mails. Shared locking can be used for flag update locking since each flag update can be atomically changed by writing one byte. Appending mails can be done by either locking existing file and appending to it, or creating a new file. If appending to a new file, create it with .lock suffix and then check that the file without .lock wasn't already just created to prevent race conditions. When appending to existing file, check "Append offset" from file's header. If that offset is at the end of file, just append there. Otherwise read the mail's header from there. If it has a non-zero UID and index file says that the same UID exists in this file, jump over the mail and do the same checks for all the rest of the mails in the file. Once the check doesn't match or you reach EOF, update the append offset in the header to that offset and write your mail there. Initially write the UID in mail's header as zeroes ('0', not NUL). Once the append is completely finished, you'll have to update it with the new UID. You'll do this by locking index file, reading the latest last-used-uid and using the next value for your UID. Once you've written it, rewrite the index file with updated last-used-uid field and your UID added to it. After this, update the append offset in the mail file and unlock it. If fcntl() locking is used, locking only specific ranges can give more concurrency. Flag updates only need to lock the part of the file they're modifying. Expunges need to lock the part which it's removing. Appending needs to lock from <end of file-1> to end of file (ie. l_len=0). Keywords file ------------- Named "index.keywords". This contains mappings between keyword numbers and names. TODO: write how it's updated Recent file ----------- "index.recent.<uid>" file tells what the last non-recent UID was. The file doesn't have any data inside it. When opening the mailbox you should find and rename() the existing index.recent.<uid> file to the new index.recent.<last-uid>. A successful rename() means the mails between <uid>+1 .. <last-uid> are recent for you. A failed rename() means that someone else managed to do it. You should look for the file again and if it was renamed to less than <last-uid>, you should try again. Nightly cleanups ---------------- Because expunged mails may be left lying around for a while, there probably should be some nightly check that cleans them up. Other cleanups that may be necessary after crashes are: - .lock files - expunged data at the end of files (can be checked with same rules as how appending determines the offset where to append) Alternative ways to use ----------------------- Expunging mails isn't very filesystem quota friendly since it requires creating another file to copy the expunged mails to. This could also be done by just moving the data within the file. This however requires that all file reads must also be shared-locked. Also it has the problem of leaving the mailbox corrupted if the copying gets aborted in the middle. For the best performance the mail flags could be stored only in Dovecot's index files. In that case the flag update locking isn't slowing down expunges (and if fcntl() locks can't be used, doesn't slow down appends either). Also there's no need for keywords/recent files. Compatibility ------------- If needed, it would be possible to create new/ and tmp/ directories under the mailbox to allow mail deliveries to be in maildir format. The maildir files would be then either just moved or maybe be appended to existing mail files.

[Dovecot] Mail directory funkiness
by Ted Kaczmarek 27 Sep '05

27 Sep '05

I am using dovecot-0.99.14-4.fc4 on FC4, was testing using mbox and than switched to using Maildir. default_mail_env = maildir:~/Maildir >From evolution when I create a folder the folder is created in ~/mail instead of ~/Maildir I am still rather new to dovecot, but this does not make sense. I made sure to restart dovecot, even added a .procmailrc. cat .procmailrc MAILDIR=/home/tedkaz/Maildir :0 ./ I am going to grab the latest version and test with that, but if if anyone has insight into how I got here it would be appreciated :-) Likely a pilot error.

[Dovecot] Misbehavior with Dovecot and Mulberry
by Jon Roma 27 Sep '05

27 Sep '05

I'm having a bit of misbehavior wherein Dovecot seems to refuse to cooperate with my Mulberry MUA. By and large, everything works great. I can move mail back and forth happily. I can compose a note and copy the outgoing mail to my Dovecot "Sent" folder using my default Mulberry settings. But if I reply or forward a mail, I get a Mulberry error popup saying that it "couldn't decode the response from the server" and that the operation was unsuccessful. This was somewhat mystifying (especially since this does work for a newly composed message as opposed to a reply/forward), so I turned on Mulberry logging. This is what I see (with unrelated operations clipped from the log). First, the first case where I create a new message, send it, and save a copy in my Sent folder: --> #6.3408 Mon Sep 5 23:24:27 2005 A00085 APPEND Sent (\Seen) {418+} * 5544 EXISTS * 1 RECENT A00085 OK Append completed. All's well there. Mulberry does a FETCH to grab the new message (reply) from my Sent folder and then does a SORT so that it can order it properly in the display. This too succeeds but is probably irrelevant to us. After a couple NOOP commands come and go in the background, I try to reply to a message in one of my mailboxes. In this case it happens to be the one in my Sent folder. So Mulberry issues a FETCH (you can see the original mail there in the FETCH response from Dovecot). It then does a STORE of the original mail, apparently to update the \Answered flag. It then tries to APPEND the reply to the Sent folder, but this time, the server comes back with a NO. See below --> #6.3408 Mon Sep 5 23:24:43 2005 A00089 FETCH 5544 (BODY[1]) * 5544 FETCH (BODY[1] {63} ) A00089 OK Fetch completed. --> #6.3408 Mon Sep 5 23:25:13 2005 A00090 FETCH 5544 (RFC822.HEADER) * 5544 FETCH (RFC822.HEADER {355} Date: Mon, 05 Sep 2005 23:24:27 -0500 From: Jon Roma <roma(a)uiuc.edu> To: Jon R Roma <roma(a)uiuc.edu> Subject: Test 1 Message-ID: <DDDD999F0F4E38F8C1510CC8(a)jrr2.isdn.uiuc.edu> X-Mailer: Mulberry/3.1.6 (Win32) MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit Content-Disposition: inline ) A00090 OK Fetch completed. --> #6.3408 Mon Sep 5 23:25:13 2005 A00091 STORE 5544 +FLAGS (\Answered) * 5544 FETCH (FLAGS (\Answered \Seen \Recent)) A00091 OK Store completed. --> #6.3408 Mon Sep 5 23:25:13 2005 A00092 APPEND Sent (\Seen) {610+} A00092 NO I am having similar problem saving a draft to my Drafts folder and suspect the same thing is behind both of these. I didn't create a Mulberry trace log for this but can do so if need be. I am running 1.0-test80 with Timo's patch to fix the "time off by 200 minutes" error with mbox. All my folders are maildir at this point -- I've converted them out of my UW mbx format store. My client is Mulberry 3.1.6 for Windows and the OS is AIX 5.1. This weird behavior is a mystery to me!

[Dovecot] 1.0alpha3 packages for debian
by Jaldhar H. Vyas 26 Sep '05

26 Sep '05

Sorry this took even longer than I thought but they should be arriving in unstable this afternoon. I also have a backport for stable available at http://www.braincells.com/backports This directory is not aptable so manually install the packages for now. (Hopefully backports.org will have their sarge repository open soon. When that happens they will move there.) The configuration file format has changed so you will want to carefully check /etc/dovecot/dovecot.conf when upgrading. I forgot to put a note about that in NEWS.debian sorry. I think I might have forgotten a couple of config file tweaks people have suggested and in general, if you sent me mail in the past month or so and I didn't respond or the problem still isn't fixed, please give me a nudge. This is why you really ought to use the Debian bug tracking system rather than mailing the maintainer. Anyway, enjoy. -- Jaldhar H.

[Dovecot] virtual domain
by Barry Kwok 26 Sep '05

26 Sep '05

we are currently using vm-pop3d to implement virtual domains. But due to some locking problem in vm-pop3d, we want to test the possibility to change to dovecot. Currently, in vm-pop3d, the passwd file is located in /etc/virtual/domain1.com/passwd /etc/virtual/domain2.com/passwd and the passwd format is: user: md5 encrpted password and the email is store in /var/spool/virtual/domain1.com/user /var/spool/virtual/domain2.com/user and we login as user(a)domain1.com, user(a)domain2.com . We want to maintain this format as login id and the password format. What should be changed in dovecot.conf? Thanks.

Hello, I'm trying to set up dovecot as the delivery agent for postfix. I configured postfix with: mailbox_command = = /usr/local/libexec/dovecot/deliver In the logs I see the following error: Sep 20 17:19:26 zalm deliver: open(/var/mail/.temp.zalm.8045.65c09c28953ea20c) failed: Permission denied Sep 20 17:19:26 zalm deliver: file_lock_dotlock() failed with mbox file /var/mail/rgevaert: Permission denied Sep 20 17:19:26 zalm postfix/local[8044]: 9790BBE4A: to=<rgevaert(a)zalm.ugent.be>, relay=local, delay=0, status=deferred (temporary failure) Info: zalm:~# ls -ld /var/mail drwxrwsr-x 2 root mail 4096 Sep 20 16:56 /var/mail Giving o write access to the folder fixed it, but not in a way it has to be :) I already added mail_extra_groups = mail to dovecot.conf But this doesn't help.

[Dovecot] auth protocol, buffers
by Thomas Hummel 24 Sep '05

24 Sep '05

Hello Timo, I'm curious about 2 points (I'm using alpha2 but these are general questions) : Background : . I connect to dovecot-1.0.alpha2 through thunderbird . I use ldap pass/userdb and PLAIN mech . I've only got one auth block in dovecot.conf (all pass/userdb/mech except ldap/PLAIN are commented) 1) I notice that, for one thunderbird connection trial, imap-login issues 2 AUTH messages. Why ? What info does the "resp=" hold the second time ? It goes like this : Info: Dovecot v1.0.alpha2 starting up Info: auth(default): client in: AUTH 1 PLAIN service=IMAP lip=xxx.xxx.xxx.xxx rip=xxx.xxx.xxx.xxx Info: auth(default): client out: CONT 1 Info: auth(default): client in: CONT 1 AGRvdmV0ZXN0AGZvbw== Info: auth(default): ldap(dovetest,xxx.xxx.xxx.xxx): base=ou=personnes, dc=pasteur, dc=fr scope=subtree filter=(&(objectClass=posixAccount)(uid=dovetest)) fields=uid,userPassword Info: auth(default): ldap(dovetest,xxx.xxx.xxx.xxx): userPassword(password)={CRYPT}sa8ufSVwLUHVU uid(user)=dovetest Info: auth(default): client out: FAIL 1 user=dovetest Info: auth(default): client in: AUTH 2 PLAIN service=IMAP lip=xxx.xxx.xxx.xxx rip=xxx.xxx.xxx.xxx resp=AGRvdmV0ZXN0AGZvbw== Info: auth(default): ldap(dovetest,157.99.64.42): base=ou=personnes, dc=pasteur, dc=fr scope=subtree filter=(&(objectClass=posixAccount)(uid=dovetest)) fields=uid,userPassword Info: auth(default): ldap(dovetest,157.99.64.42): userPassword(password)={CRYPT}sa8ufSVwLUHVU uid(user)=dovetest dovecot: Sep 20 17:58:27 Info: auth(default): client out: FAIL 2 user=dovetest 2) Which buffer/string handling function (among those in your lib) should I use to safely allocate a string and/or copy a string into another ? (instead of using str[n|l]cpy for instance) ? Thank you. -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] 1.0 alpha3 released
by Timo Sirainen 24 Sep '05

24 Sep '05

I'm a bit too busy nowadays because of school so I haven't had time to look at everyone's bug reports and some other mails. They're still marked as unread in my mailbox, so hopefully I'll get to them soon. And I don't mind you resend them if I don't answer in a few weeks :) Changes: - Fixed maildir syncing errors about wrong UIDs - Maildir was re-read all the time, even if we knew nothing had changed there - SSL/TLS connections used to have extra ~0.2s latencies because kernel was waiting for more data before sending it (at least with Linux). Fixed it by corking/uncorking before/after sending. I don't think the socket latencies are this bad normally though, I should probably look more into it if we're setting some socket flags badly (or does it happen specifically because we were using corking for the socket before SSL and kernel increased the timeouts because it thinks we're going to be using corking?). - Marking index file corrupted caused its recreation to still use old transaction log file, which usually caused the index to get corrupted again - Added --build-options parameter to dovecot binary (by Andrey Panin) - Parse obs-phrase correctly in mail address parser (by Chris Wakelin)

[Dovecot] dovecot with ssl only works on foreground mode
by blaq b0x 24 Sep '05

24 Sep '05

Hi, I've set up dovecot to use imaps/pops with certificates that I signed with my own CA. When I try to start it using service dovecot start it fails. I've tried disabling imaps in the config file and it starts fine so it seems it's the certificate part of the config. If,however, I start it with '/usr/sbin/dovecot -F' or even '/usr/sbin/dovecot' it starts! I've looked over the dovecot startup script but, can't seem to see anything that would hinder startup. I didn't have this problem with self-signed certs??? Can anyone shed some light on this? Thanks, __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

[Dovecot] Maildir and folders not under INBOX
by Oliver Schulze L. 24 Sep '05

24 Sep '05

Hi, I'm planning to migrate from dovecot/mbox to dovecot/maildir both using imap. I have read that when using the Maildir storage format, all folders are stored under the INBOX. Is this true in dovecot too? I want to have a configuration like the current: - new mail is delivered in /var/mail/USER - user folders are in /home/USER/mail I want to ask if this is posible in dovecot? Maybe using a config like this: default_mail_env = maildir:/home/%u/Maildir:INBOX=/var/mail/%u/Maildir Thanks Oliver -- Oliver Schulze L. <oliver(a)samera.com.py>

[Dovecot] Moving messages takes a longgggggg..... time. (Timeouts?) dovecot.conf help?
by Rob Frohne 23 Sep '05

23 Sep '05

Hi, I'm trying to get dovecot set up better. I am using 1.0alpha3. It takes a long long time to move messages for some reason. It seems it may be a timeout thing, because neither the client or server is using any cpu time or disk i/o or network to speak of. (To move maybe 400 messages, it seems to take maybe half an hour, maybe longer.) With alpha 2 I was getting messages from Thunderbird saying that the server was unable to move messages, would I like to continue. I haven't seen any of these lately, but when I updated to alpha3 I also made some dovecot.conf changes. I'm running this on OS X with a 450 MHz cube with 1.2 Gig of ram and a 7200 RPM hard drive. I have a lot of rules that move messages to various mailboxes and I get a lot of mail, so this is important to me. I have a very large Maildir set of mailboxes (about 40 of them with up to 70,000 messages in each mailbox). I have finally got it so that it will load the mailbox headers pretty quickly in Thunderbird. It takes about 15 to 30 seconds to load a message, but that is acceptable to me. Here is my dovecot.conf. Can anyone give me some tips? ## Dovecot 1.0 configuration file # '#' character and everything after it is treated as comments. Extra spaces # and tabs are ignored.

[Dovecot] signing dovecot certs with own Cert. Auth.
by blaq b0x 23 Sep '05

23 Sep '05

Hi, I'm trying to get apache, sendmail , and dovecot to use SSL certs signed by my own CA. I've got the apache certs working fine. However, dovecot ( I haven't even tried sendmail yet) doesn't seem to accept any of the certificates that I create for it. There is a script that comes with dovecot that creates self-signed certificates for you but, I need certificates signed by my own CA. I found this tutorial http://homepage.mac.com/pauljlucas/personal/macmini/certs.html it shows you how to create a csr for dovecot that you can send to a CA. I signed it using CA.pl -sign. however, the certificate isn't accepted by dovecot. Unfortunately, dovecot doesn't log anything to maillog at failed startup. Just looking at the certificate contents I noticed that the self-signed certificates don't have all kinds of publisher information at the beginning of them like the apache certs. So I think what I'm missing is the difference between all the different cert types. I know that there are pem and cert ssl cert types, at least different extensions. Can anyone tell my what the difference is? are the certs suitable for apache and others for mail applications? is there a converter? Could it be the way that I'm signing the certificates? Any help would be appreciated. Thanks, Reply With Quote __________________________________ Yahoo! Mail - PC Magazine Editors' Choice 2005 http://mail.yahoo.com

[Dovecot] Lost transaction log file in alpha2
by James Berry 23 Sep '05

23 Sep '05

I had run alpha1 pretty uneventfully for several weeks. I upgraded to alpha2 a couple of days ago and have since suffered two incidents of "Lost transaction log", resulting in the client being unable to access the mailbox until I "rm dovecot.index.log*" Sep 14 10:48:35 caddy dovecot: imap(jberry): Lost transaction log file /Users/jberry/Maildir/dovecot.index.log seq 1 I should point out that this is a server with a single imap user (myself) and that I know only one imap client was trying to access the server at that point in time (though the client sw Mail.app may have had multiple connections to the server). Any suggestions/ideas/thoughts on whether something might have changed in alpha2 to start causing this? James.

[Dovecot] auth-master socket access
by Lieven Van Acker 23 Sep '05

23 Sep '05

Hey, I'm doing a setup of dovecot (cvs) + postfix + dovecot lda (cvs). Is there any solution to the /var/run/dovecot/auth-master access restrictions, prohibiting the user running dovecot-deliver from communicating with the master (aside from the dirty and unsafe hack to reset the permissions of the /var/run/dovecot dir after starting dovecot)? Thanks, Lieven

[Dovecot] Can't donwload mails with some attacchments
by Lethux 23 Sep '05

23 Sep '05

Hi. Does anyone find the same problem with attachments bigger than few Ks? The client (thunderbird) waits for the file to be downloaded. It can be waiting for several minuts and tryies before having it from dovecot. Can it be something against the lock of the file, the processes or something else? Any workaround or bugfix in the stable/alpha rel? thanks. L.

[Dovecot] Is Alpha2 slower than Alpha1?

[Dovecot] Basic namespaces question
by David King 23 Sep '05

23 Sep '05

I can't find a generalised "What the heck are namespaces all about?" anywhere, can anyone point me to a decent one? More directly, my question is this: if I set up two non-hidden private namespaces (one for mbox and one for maildir), will a well-written IMAP client automagically list folders from both as if they were part of (or below) the same hierarchy, or do I have to set up two accounts, one with a prefix of (say) #mbox and one of #maildir? One step further, I'd like to eventually get mail from /var/mail/%u in mbox format, and in "maildir:%h/.maildir" or "mbox:%h/.mail", whichever exists (I'm migrating from imap-uw, and would like the benefits of maildir without forcing users to change their mailstores in case they use pop3 or tools like mail(1)). I'm willing to do some coding for it, but I imagine that it would be non-trivial if namespaces aren't automatically integrated

[Dovecot] bug? Maildir ... sync: UID inserted in the middle of mailbox

23 Sep '05

Version: 1.00alpha2 Error: imap(grin): Maildir /home/grin/Maildir sync: UID < next_uid (94 < 95, file = 1127311363.H977932P25148.gollum:2,) imap(grin): Maildir /home/grin/Maildir sync: UID inserted in the middle of mailbox (95 > 94, file = 1127311363.H977932P25148.gollum:2,) This error reappears frequently. Doesn't go away by restarting dovecot, but does go away when I delete all index and cache and whatnot (and restart dovecot). Appears in 10 minutes again... Could be sylpheed-claws-whatever-alpha imap problem, but whatever the client does dovecot shouldn't be fall apart I believe. Peter

[Dovecot] Another address-spec problem
by Chris Wakelin 23 Sep '05

23 Sep '05

I've had complaints from users about "MISSING_DOMAIN" in header fields and I've tracked it down to having "." in an unquoted display name. By my reading of RFC2822 (especially section 4.1) A N Other <a.n.other(a)somewhere.org> "A. N. Other" <a.n.other(a)somewhere.org> are legal, but A. N. Other <a.n.other(a)somewhere.org> is "obsolete", but should be supported by the server (no clients should do it). I think the relevant syntax is phrase = 1*word / obs-phrase word = atom / quoted-string obs-phrase = word *(word / "." / CFWS) and rfc822_parse_phrase() should be modified to cope with "obs-phrase". I'll have a go, but if Timo or anybody knows how to do it properly, that would be better!

I just set up postfix with some virtual domains and users. Dovecot made some dbs in /etc/dovecot. a passdb and userdb. the passdb file has passwords in there and I want to at least know what it is. I have tried to do 'echo -n mypassword | openssl md5 -hex' and insert that into them but it seems to not work. Probably something I am doing wrong. I looked at the archive and could not figure out how to search it. Anyway how do i change a password?

[Dovecot] problem with postgreSQL connect=
by octane indice 22 Sep '05

22 Sep '05

Hello I'm using dovecot with virtual accounts stored in a postgreSQL db. I use in the dovecot.conf: auth_userdb = pgsql /usr/local/etc/dovecot-pgsql-user.conf (and same for pass). In the file dovecot-pgsql-user.conf, I use: connect = host=127.0.0.1 dbname=vmail user=lecteur password=lire user_query = SELECT '/var/spool/vhosts/'||nom_domaine||'/'||nom_boite AS mail,5000 AS uid, 5000 AS gid FROM boites WHERE email = '%u' It doesn't work. If I write: connect = dbname=vmail user=lecteur user_query = SELECT '/var/spool/vhosts/'||nom_domaine||'/'||nom_boite AS mail,5000 AS uid, 5000 AS gid FROM boites WHERE email = '%u' It works. Of course the query with psql works: psql -U lecteur -h 127.0.0.1 vmail -c "SELECT '/var/spool/vhosts/'||nom_domaine||'/'||nom_boite AS mail,5000 AS uid, 5000 AS gid FROM boites WHERE email = '%u' " with the password 'lire' My question: do I make something wrong? I want to use the network, because in future, dovecot will not be on the same host than postgreSQL. Thanks --------------------------------------------- Etes vous un consom'Acteur ?

[Dovecot] Weird series of errors with dovecot-stable

I'm using the dovecot-stable from 7/30, authenticating against an OpenLDAP server. From time to time, dovecot stops responding to new queries. It seems to be a self-correcting problem, lasting about 20 minutes. Here's how it starts: Aug 18 19:38:23 cliff dovecot: imap-login: Disconnected: Inactivity [150.253.42.12] Aug 18 19:38:36 cliff dovecot: pop3-login: Disconnected: Inactivity [68.46.174.217] Aug 18 19:39:35 cliff dovecot: imap-login: Disconnected: Inactivity [150.253.42.12] Normally I see almost no "Disconnected: Inactivity" messages, but when this problem shows up I get an almost non-stop barrage of them.

[Dovecot] ALL TCP/IP connection REST when one mail contains format error
by Yi Xuan 20 Sep '05

20 Sep '05

Hi, I have setup a dovecot pop3 server on IP_A and using mbox format I have 6 users behind a NATed network, the public IP is IP_B. And one mail of one user seems contain format error. He always cannot receive the 5th mail from anywhere. Then when he receive mail in the intranet, all the TCP/IP connection REST between IP_A and IP_B. http/ssh/pop/smtp etc. all NG. After I delete the 5th mail from webmail, then the services work well. 1.It seems unreasonable, Can dovecot improve it and let it donot influence other users and other service? 2.What may cause mbox format error? and how can we avoid it? Best regards,

[Dovecot] Two strange behaviours with dovecot+postfix+squirrelmail
by Francisco Neira 20 Sep '05

20 Sep '05

Hi all, About a week ago I was forced to migrate my main (production) email server from RH9 to Centos4.1. The installation has dovecot-0.99.11 + postfix-2.1.5 and >600 mbox accessed email accounts. Number 1. Some users accessing thru squirremail (installed in my webserver) can read their INBOX at /var/spool/mail directory but when trying to delete a message they receive the following error message from squirrelmail: ERROR: Could not complete request. Consulta: COPY 1279 "mail/Trash" Reason Given: Internal error occured. Error report written to server log. [2005-09-16 15:08:04] and the error logged is the following: Sep 16 15:09:27 mail imap(username): mkdir_parents(/home/username//mail/.imap/Trash) failed: Permission denied I never stated that .imap/Trash when configuring dovecot and the strangest thing is that my account, as most of others, can delete messages moving from /var/spool/mail/my_name to /home/my_name/mail/Trash Number 2. Randomly, some users connecting from Mozilla Thunderbird via IMAP get an error message telling that there has been an error connecting to INBOX. Watching the maillog I found the following: Sep 16 13:07:43 mail imap(otheruser): File isn't in mbox format: /var/spool/mail/otheruser I accessed the user's inbox file with vi and found that there was a "--604" at the beginning of the file. In other case I found that the file was beginning with a truncated email message. Trying to "walk on the safer side", I changed the mbox_lock setting from "fcntl" to "dotlock" in the /etc/dovecot.conf file. Any suggestions and comments about his will be highly appreciated. Forgive me about my English, it is not my native lanaguage. Regards, -- Francisco Neira B. Administrador de Red Defensoria del Pueblo Lima, Peru, -05:00 UTC

[Dovecot] NO: Unsupported authentication mechanism
by Steve [Dovecot] 19 Sep '05

19 Sep '05

I'm happily using dovecot as my IMAP server and accessing mails using Thunderbird... but I want to use the Net::IMAP facilities in the Ruby standard library to write some scripts to automate various spam-related tasks & housekeeping. My Ruby script: require "net/imap" imap = Net::IMAP.new('localhost') imap.authenticate('LOGIN','myuser','mypassword') # More stuff using imap... From the documentation LOGIN uses plaintext authentication - which I understand is always acceptable for Dovecot when connecting from localhost. On the 3rd line I get a "NO response" exception raised (indicating that the IMAP server replied "NO") and the error message "Net::IMAP::NoResponseError: Unsupported authentication mechanism" If I change 'LOGIN' to 'CRAM-MD5' (the other value supported by Net::IMAP) then I get a similar (but not identical) error: "Net::IMAP::NoResponseError: Authentication failed: Unsupported authentication mechanism" If I use anything other than either 'LOGIN' or 'CRAM-MD5' I get an error from the Net::IMAP library saying "Unknown auth type" - which is reasonable. N.B. I've tried both where 'myuser' and 'mypassword' are valid - and not... this doesn't affect the error messages. There doesn't seem to be anything of interest in /var/log/messages... Can anyone tell me what is going wrong, and how to resolve this?

[Dovecot] FreeBSD port
by David King 19 Sep '05

19 Sep '05

FreeBSD users: I notice that the version of Dovecot in the FreeBSD ports system is back at .99. Are there any objections to my submitting an update to the FreeBSD ports for version 1.0a? Is it better to wait for 1.0 to be progressed a little or is it considered to be ready? 1.0a compiles and seems to run fine (on 5.3), so are there any obvious patches that would be needed for the FreeBSD build? -- Don't forget that 19 September is National Talk-Like-A-Pirate Day! http://www.talklikeapirate.com/piratehome.html

[Dovecot] Very minor feature request
by Steffen Kaiser 19 Sep '05

19 Sep '05

Hello, I'd suggest a way to get to know the "capabilities" of a compiled Dovecot. The background is that I've run the sequence ./configure --with-ldap && make && make install twice, all three commands tell me that all is fine (ldap is listed in the modules), but still dovecot told me that ldap is no Usedb module. A "make clean" before solved the problem -- well, something one should anyway. Besides, the "dovecot --capabilities" should also list all the defaults. Bye, -- Steffen Kaiser

Hi, my name is Andrés Rusconi, from Tucumán, Argentina. Sorry my English, please. I am a very happy new user of Dovecot: I gained speed and simplicity with him. But I noticed that in clients who use Outlook, the deleted messages do not copy to the trash folder. This is not critical, but did not happen with Courier, and the users askme about this behavior. If some of you has somehow solved this small question, I will thank for their commentary. Saludos Andrés

The thing is, it keeps happening and I can't figure out why. Email clients that send mail to these accounts are the latest Outlook Express. As I said, I have 150+ users on the same system and they are fine. I'm not sure if protocol makes a difference, but we are using POP3 only. Any ideas what I can do to fix/prevent/correct this either programatically or with a patch of some sort? Is this actively being worked on? I'm running FC4 with dovecot-0.99.14-4.fc4.

[Dovecot] Dual INBOX Locations

G'day list, Just a quick question - I need to configure Dovecot to do the following: * check default_mail_env for the users' inbox in MBOX format * If the above fails, serve the user an inbox from a secondary location, in MAILDIR format. I have read up on Namespaces, however I can't seem to get this to work - login just fails when Dovecot cannot find the inbox in default_mail_env Any advice, anyone? :) Thanks, Calum -- Calum Power Systems Administrator Server101 Pty.

[Dovecot] problems with Auth and Alpha 1a
by Søren Peter Skou 18 Sep '05

18 Sep '05

Hi all I'm not quite sure how to explain this problem, so I'll just go from the top ;-). System is setup on a FreeBSD with IMAP and POP3, both can use PAM and SQL (MySQL) as login methods, though only POP3 is accessible from "the world" - IMAP is restricted via firewall to only localhost. Simple eh? The problem is that dovecot apparently drops the SQL part from time to time. Though this can be fixed by HUPing the dovecotdaemon I'd rather that I didn't have to. I've narrowed the problem to something like this: Over time, Dovecot/POP3/SQL combination dies - I've yet to examine if the problem is on IMAP as well as this is only recently reported. I have never experienced this myself since I'm using Dovecot/IMAP/PAM and this seems to be rock solid. The configuration looks like this: OS: FreeBSD n/a 6.0-BETA3 FreeBSD 6.0-BETA3 #0: MySQL: 5.0.9-beta-log Dovecot: alpha 1 (I'll test Alpha 2 to see if the problem persists) Compilation options for dovecot: ./configure \ --enable-ipv6=no \ --with-ldap=no \ --with-vpopmail=no \ --with-mysql \ --with-ssl=no dovecot.conf: base_dir = /var/run/dovecot/ protocols = imap pop3 ssl_disable = yes disable_plaintext_auth = no login_user = dovecot login_process_per_connection = no login_greeting = Ready max_mail_processes = 1024 first_valid_uid = 1 first_valid_gid = 1 protocol imap { } protocol pop3 { } auth default { mechanisms = plain passdb pam { } userdb passwd { } passdb sql { args = /usr/local/etc/dovecot/mysql.conf } userdb sql { args = /usr/local/etc/dovecot/mysql.conf } user = root } -- END -- sql.conf: driver = mysql connect = host=localhost port=3306 dbname=N/A user=N/A password=N/A client_flags=0 default_pass_scheme = CRYPT password_query = SELECT password FROM mail WHERE username = '%n' and domain= '%d' user_query = SELECT concat('/VIRTUAL_MAIL/',domain,'/',username,'/') as home,concat('/VIRTUAL_MAIL/',domain,'/',username,'/') as mail, 1 as uid, 6 as gid FROM mail WHERE username = '%n' and domain = '%d' -- END -- I'm sort of at a loss here since everything "seems to be working" (tm) for one part, but not another Hope someone has an idea ;-) Søren P.

I hava bog standard install of 0.99.10.8, on an openbsd 3.6 box. every now and then i get an error from my or my users' IMAP email client saying that it couldn't access a particular inbox. a few clicks of "OK" or "Cancel" etc and the problem seems to go away. all kinds of errors (similar to above) in the imapd logfile though, seem to correspond with the timing of the abovementioned IMAP mail client errors. one thing: my users DO use procmail, so there is a chance that their IMAP client might have a mailbox open that procmail may be trying to append to. i wonder if this is a locking issue? i guess what i'm asking is - 2 thing: 1) how can i get these pesky imap client errors to go away so my users mailboxes can be successfully selected? 2) what do the indexing errors mean? are the 2 things related? Thanks so very much in advance everyone! Best, Rick. rick tait | e: rickt(a)rickt.org | t: 323.829.5703

[Dovecot] Timeout while waiting for lock....
by Rob Frohne 16 Sep '05

16 Sep '05

Hi, I'm very new to administering mail, and this is surely a newbie question. I have my own IMAP mail server because I use my email as a way of filing important things, and I subscribe to a number of lists that I like to archive. I have about 40 mailboxes with up to 80,000 messages in some, and one with 40,000 messages is almost a Gigabyte in size. The total size is around 4 Gigabytes. Things were working quite well until I upgraded to OS X 10.4 and its new Mail.app mail client and then everything was too slow. I was using the UW IMAP server (2002d if I recall right) and Mail.app 1.3.9. I tried upgrading the server to the latest, but it didn't improve things noticeably. I swapped to dovecot 1.0alpha1, and used the mbox format, but that wasn't any better. I read that Maildir format was better, so I converted my mail to that format and tried that. It didn't seem much better. I tried to compile Cyrus on OS X and ran into all kinds of difficulty. I finally tried Cyrus on a Linux box, and turned off all my rules that move messages around. In comparing this to dovecot on my OS X box, Cyrus loads the messages significantly faster. I think there are some problems with my dovecot setup though. My mail.log is filled with this type of thing.

Can anyone suggest something to fix my problems, besides deleting all my email? Thanks, Rob

[Dovecot] SSL/TLS stopped working in 1.0 alpha2
by Andy Cravens 15 Sep '05

15 Sep '05

I have both 1.0 alpha1 and alpha2 installed on my test mail server. SSL/TLS does not work on alpha2. I'm using the same config file for both. No errrors in dovecot.log either. Is there a way to increase debugging info without recompiling?

[Dovecot] Dovecot-LDA problems (CVS version) Signal 11 and empty 'mail' dir
by Steffen Kaiser 14 Sep '05

14 Sep '05

Hello, I'm trying dovecot-lda (deliver.c has CVS version 1.18). When I try to deliver a mail, an empty directory is created name $HOME/mail. This is neither the configured (via LDAP) nor the default "mail" setting in the /usr/local/etc/dovecot-deliver.conf. When the $HOME directory does not exist, but the user itself: Sep 1 11:47:12 localhost deliver: mbox: Can't create root IMAP folder /home/skaise2a/mail: Permission denied Sep 1 11:47:13 localhost sm-mta[4684]: j819lCgd004682: SYSERR(root): mailer local died with signal 11 Default mail: mail = maildir:%h/.mailboxes:INDEX=/usr/local/var/spool/dovecot/indexes/%Lu Configured via LDAP for user skaise2a: maildir:/mailcache/skaise2a:INDEX=/var/cache/dovecot/indexes/skaise2a:CONTROL=/var/cache/dovecot/control/skaise2a I have only found the error message in dovecot's src/lib-storage/index/mbox/mbox-storage.c function create_root_dir(). The Dovecot logs indicate that dovecot-lda is requesting the information from it and the message is - once the empty directory could be created - delivered into the configured IMAP root.

Locking _does_ work for postfix and dovecot (discussed with Wietse, partly by mail). Any idea? As an alternative, is there a way of handling the problem better?

[Dovecot] what does this mean: Warning: Error in custom flags file / Corrupted Indexes

Hi everyone: I am seeing a whole LOT of these messages in my dovecot logfile: imap(rickt): Sep 12 17:14:03 Warning: Error in custom flags file / home/rickt/mail/.imap/TRASH/.customflags: Duplicated ID 0 imap(rickt): Sep 12 17:14:03 Warning: Error in custom flags file / home/rickt/mail/.imap/TRASH/.customflags: Duplicated ID 1 and also these: imap(mbwnews): Sep 12 17:10:16 Error: Corrupted index file /home/ mbwnews/mail/.imap/INBOX/.imap.index: used_file_size larger than real file size (2016 vs 1608) imap(mbwnews): Sep 12 17:10:18 Error: Corrupted index file /home/ mbwnews/mail/.imap/INBOX/.imap.index: used_file_size larger than real file size (2016 vs 1608) And not just referring to my inbox, other users as well. I hava bog standard install of 0.99.10.8, on an openbsd 3.6 box. every now and then i get an error from my or my users' IMAP email client saying that it couldn't access a particular inbox. a few clicks of "OK" or "Cancel" etc and the problem seems to go away. all kinds of errors (similar to above) in the imapd logfile though, seem to correspond with the timing of the abovementioned IMAP mail client errors. one thing: my users DO use procmail, so there is a chance that their IMAP client might have a mailbox open that procmail may be trying to append to. i wonder if this is a locking issue? i guess what i'm asking is - 2 thing: 1) how can i get these pesky imap client errors to go away so my users mailboxes can be successfully selected? 2) what do the indexing errors mean? are the 2 things related? Thanks so very much in advance everyone! Best, Rick. rick tait | e: rickt(a)rickt.org | t: 323.829.5703

[Dovecot] An alternate "dovecot-auth" daemon using cyrus-sasl
by buc 12 Sep '05

12 Sep '05

We use dovecot in a heterogeneous environment (Windows/Linux desktops and Linux servers). For unified authentication we use a sheaf "Samba/Openldap" (i.e., Samba NT domain with openldap backend and pam/nss_ldap for Linux). Windows users are authenticated well everywhere, but there is one old issue. As "SPA" (NTLM) against NT domain is not supported by dovecot, it is necessary to use default "plain" method. In addition to security problems, it does also a problem of password unification. Each time a user changes the password, he should do it one more time for the mail program. I know that dovecot supports NTLM, however against local database only (not for NT domain controller). In early versions support of cyrus-sasl (which supports NTLM now) had been incorporated, however it like not work and now is removed. Fortunately, there is a possibility to substitute dovecot-auth executable. Therefore I have tried to make an alternate variant of dovecot-auth, which supports all that we need. For us, it seems to be more useful to create an auth daemon using cyrus-sasl, rather than to add domain support to existing ntlm code. First of all, it is easier for implementation. Besides it enables use of all mechanisms supported by cyrus-sasl (present and future), including GSSAPI. Anyway, it will be the useful additive to dovecot. I have made appropriate patches for both dovecot-1.0-stable and dovecot-1.0.alpha1. The idea is to copy "src/auth" to "src/auth-cyrus", strip all unneeded from newly created directory and add cyrus-sasl support. The resulting code probably looks not so elegantly as if it has been written separately, however this way allows to not make a lot of things from the scratch. The patch against 1.0.alpha1 is here: http://dmitry.butskoy.name/dovecot/dovecot-1.0.alpha1-cyrus.tar.gz . To be more readable, it is not a flat patch (due to a lot of whole files add/remove). It is a tarball with 3 files: a list of files to initial copy from auth/ to auth-cyrus/, a patch for resulting tree, and a script which automates this steps (:-)). (The script should be run in the root of the main source, i.e. a dir with src/ and doc/ subdirs). I already have successfully tested this patch with PLAIN method. However before testing of other methods, it would be desirable that somebody have looked at it. Whether someone could check up my patch (just fluently having read), at least for obvious bugs and typos?

[Dovecot] Dovecot feature request: move /var/mail/uid to INBOX
by Steffen Kaiser 12 Sep '05

12 Sep '05

Hello, UW-Imap has a (questional, but for me useful) feature to slurp all mails pending in /var/mail/uid into the user's INBOX whenever the user successfully logs on and the INBOX is not configured as /var/mail/uid. The usefulness for me is that users have a relatively small quota, so the noisy "over quota" messages pop up for everyone now and then, regardless how frequent one reads the mail. When I now set a large quota for the "pending INBOX", where the user (aka dovecot) can only delete mails from, I circumvent those messages, prevent that users use the (large) INBOX as yet another place to pile up data (the user does not know about the pending INBOX at all) and let the users have "full" control over their folders. The disadvantage is that it works for "real" users only. Another disadvantage is that one would expect "LDA"-features in the server portion of Dovecot, e.g. Sieve :-), or the server would need to spawn the Dovecot-LDA somehow. (Next thing is that, currently, the mails are delivered into the home directory of the users, what leads to several annoyances when someone is away for some time and finds his home directory locked, because the mass of mails locked the directory. Mostover, those IMAP servers I ran so far didn't allowed the user to delete a mail via IMAP often, because some temp or arbitary file couldn't created in the IMAP root. Because the user is already logged on onto Dovecot, there should be less problems deleting mails when the quota exceeds while slurping them in. At least I had extremly good experiences with this mechanism, when I used UW-Imap and the INBOX was located as mbx in the user's homedirectory.) Bye, -- Steffen Kaiser

[Dovecot] reading subfolders with mail.app

Hi all, I have been having a hard time using Fedora Core 4 with dovecot +sendmail. Namely, I cannot read my home dir's procmail filtering dir (where I have some subfolders) in ~/mail. I cannot create mailboxes either. I'm wondering if this is a client issue, and whether I need to switch to Maildir, which I'd like to do, but don't know how to with sendmail (with postfix, it's a piece of cake). Any advice on what my problem is? I'm all ears! regards, Patrick

[Dovecot] 1.0alpha2 released
by Timo Sirainen 12 Sep '05

12 Sep '05

Changes: - Some cache file corruption fixes (shouldn't be any left?) - Some index file fixes with mmap_disable=yes - Some mbox syncing fixes - Timezones in mbox From-lines were handled wrong - Added pop3_reuse_xuidl setting. Patch by Chris Wakelin - "stack frame changed" crashfix for FETCH BODYSTRUCTURE - Added %R (reverse string) and %H (hash string) variable modifiers. These can be useful if you want to automatically split users to multiple partitions (eg. %3RHu gives values 0..2 based on the given username). See doc/variables.txt for more information. The POP3 bug mentioned in ChangeLog doesn't actually exist, so don't be alarmed by it :)

[Dovecot] Do index files need removing when upgrading 1.0-stable to 1.0-alpha1 or later?

Hi Timo, Just a quick question: do index files still need removing when upgrading from 1.0-stable (as in the testXX series) or will Dovecot regenerate them automatically? I'm expecting to go with 1.0-stable on Tuesday for my 20,000 users (as that's what I've been testing), but if we see lots of index issues, I may want to upgrade to alpha1 (or later) fairly soon afterwards and it would be annoying to have do delete thousands of indexes!

[Dovecot] subscriptions or .subscriptions?

I may have found a problem with the documentation concerning the subscriptions file. On the Dovecot web site there is a document that outlines the conversion from UW IMAP to Dovecot. The document says Dovecot's folder list is stored in ".subscriptions" However, I have found that Dovecot's folder list is really "subscriptions" without the preceding dot. Did Dovecot version 1.0.alpha1 remove the dot from the subscriptions filename? .subscriptions does not seem to work at all. http://wiki.dovecot.org/moin.cgi/Migration#head-5dde807bf059dea93fc2303e202…

[Dovecot] Problem in dovecot 0.99 - login username case sensitive create fake maildirs
by Max CtRiX 11 Sep '05

11 Sep '05

Hello, I have noticed a weird behaviour in dovecot 0.99 which, I hope, is not replicated in 1.0-alpha. First I have to say that it works very well. So if I login with user foo(a)bar.com, the maildir is created. But when I log in with User FOO(a)BAR.COM, or FOO(a)BAR.com, then two other maildirs are created. Authentication is ok (I'm using mysql backend) but no mails are obviously found. Maybe a solutions would be adding some config item to turn lowercase the maildir path or authentication tokens (received from client) at login time. Or maybe I am missing something. Is there a solution for this problem out there ? Thanks, Massimo

[Dovecot] POP3 problem about multi users from one IP address concurrent
by Yi Xuan 11 Sep '05

11 Sep '05

Hi,all I have a POP3 problem about multi users from one IP address concurrent. [Issue description] The network architecture is as following. I have setup a mail server(sendmail/dovecot) in PlaceA with IP_A. And about 6 users are receving mail from the same IP_B( NATed public IP) in PlaceB. Their mails are many( about 1Mb/hour each) and ususally set fetch time as 10min/fetch. Then they complain that their mails often cannot be downloaded. [Reason investigation] I noticed that 1.when one of them fail to fetch mail. All TCP IP connection between IP_A and IP_B will be RST.which means that http/ssh/pop/smtp all not work for a while. And after about 10 minute, the http/ssh can work well. 2.I have asked them to backup and delete pop accounts and use webmail through imap provided by dovecot.And that seems work well but inefficient. I think this maybe because of multi users from one IP address concurrent, [Question] Would you pls provide some suggestion or solution about this issue? Is this a bug of dovecot or just a mis-configuration I don`t know? Thanks in advance for any advice. Best regards, Yi Xuan

I can't even work out what it means, so I can't even begin to debug it. There is nothing extra in /var/log/messages, so I'm out of ideas. I've tried it with the default config, as well as with a config that I adjusted to fit the environment. I'm currently out of ideas. I did notice that there is a brief thread on this in the mailing-list archive, but it doesn't seem to point to a solution. Hopefully someone can help. I'm running it with the command /usr/local/libexec/dovecot/imap-login I am using the 1.0.alpha1 version, running on RedHat AS 3. thanks in advance.

[Dovecot] Dovecot-alpha1 and Thunderbird Sent problems
by Nicholas Young 09 Sep '05

09 Sep '05

I have dovecot 1.0alpha1 setup in a semi test environment running on Solaris 2.6. When using Thunderbird 1.0.6 from Windows occasionally the client will hang after sending a message and before copying it to the Sent folder on dovecot. Sendmail logs indicate that the message has been sent correctly. The mail directory is not shared over NFS. It is in maildir format. Restarting Thunderbird and sending exactly the same message will work. This seems to imply that it is not message dependant. Once the error has occured once it continues to occur until the client is restarted. We have file system quotas however they are very large for a very small amount of mail. The filesystem is about 80% free space and about 98% free inodes. I cannot replicate the issue under Linux using Thunderbird that is current for FC3. Some hacked version 1.0.2-1.3.3 Imap workarounds turned on under dovecot are outlook-idle for imap. The issue has not been seen under Outlook. Outlook is using a local Sent-Items folder instead of an Imap one however. The connection is running over SSL so I can not sniff the traffic on the wire, I have not tried using the rawlog settings yet. I plan to start this now, however the sporadic nature of the problem may delay useful information from here. The dovecot logs are not showing error messages, just: dovecot: Sep 09 09:24:35 Info: imap-login: Login: user=.... TLS Any suggestions on where to start would be great. This issue was not reported to me when running dovecot-1.0-stable-20050718. Thanks for any help/suggestions on where to go from here. -- Nich

[Dovecot] Ip addr + login name
by mike 08 Sep '05

08 Sep '05

Hi everybody, Is there a way to bind client ip address that connects to pop3 with the login name? For example if the client ip address is 192.168.2.40 then his login name is 'test' and he can log in with only that account name. I think it is possible to do it with an external authentication program. Thanks.

[Dovecot] More verbose logging of POP transactions?
by Philip Hallstrom 08 Sep '05

08 Sep '05

Hi all - I'm brand new to dovecot (0.99.14 on freebsd 5) and am just playing with it a bit. POP works just fine, but the only thing that shows up in my logs is this: Sep 7 11:46:25 freebsd5 pop3-login: Login: philip [10.28.61.200] Thought maybe syslog was quietly eating things, but told dovecot to use it's own log file and it didn't improve. Is there a way to turn on more detailed logging about what the user did? Along the lines of what uw-imap's pop gives you in terms of number of messages available, downloaded, deleted, etc.? I'm also interested in how much was transferred size wise... If I mised it in the conf file just let me know, but I didn't see anything... Thanks! -philip

[Dovecot] Dovecot - IMP - POP autentication problem
by Carlos Bergero 07 Sep '05

07 Sep '05

Hi, Recently I have to rush one of my mail servers to a new installation, actually GNU Linux/Debian Sarge, the system run dovecot 0.99.14 for pop and imap, and the web server, other machine, uses horde2/imp3. The problem is the following, pop clients including the imp3 cant log properly apparently, the even when a connection is made to pop3 dovecot trys to make a secure connection, I found this after sniffing the connection between the web server and the mail server, for some reason, imp cant handle it well and the some clients like OutLook also have troubles working this out. For now I work around this problem by disabling the ssl/tsl support, but that's not the solution I need. So the question is can I disable this feature without loosing the secure connection and how can I do it? Cheers, rak

[Dovecot] 1.0alpha1: new assert/core
by Jeff A. Earickson 07 Sep '05

07 Sep '05

Hi, I saw a new assert and core dump today in 1.0alpha1. Setup is Solaris 9, dovecot built with gcc 4.0.1, running as imap server for mbox format. The syslog said: IMAP(user): file message-body-search.c: line 393 (message_body_search_ctx): assertion failed: (input->v_offset <= part->physical_pos) A gdb analysis of the core dump is attached. BTW, I save core dumps in case you need further debugging done for an assert. On another note, I have also had issues with dovecot locking up with "Too many open files" syslog error messages. Last night, after several hours of "too many open files" complaints, the master dovecot process just died -- no core dump and no complaint to syslog. Per advice of the list, I have doubled the rlim_fd_cur and rlim_fd_max kernel parameters and rebooted my imap server. I also saw in my syslog: Sep 6 16:48:53 emerald dovecot: [ID 956436 mail.error] pipe() failed: Too many open files Sep 6 16:48:53 emerald dovecot: [ID 257797 mail.crit] dup2(stderr) failed: Bad file number With students back, they have been giving dovecot a real hard workout.

In 1.0 there are two executables, mail_executable launched for logins, and (from memory) auth_executable launched at daemon start, so I suppose login_executable is the wrong one :-) I diagnose the error you get as meaning that the space is not ed separat out, and that dovecot tries to fork the executable named /usr/libexec/dovecot/popbsmtp.sh /usr/libexec/dovecot/pop3-login which obviously won't work. > Permissions are 777 on the popbsmtp.sh script.

Problem with direct SQL is that I can't manage to make dovecot execute two SQL statements. If you're using a db with stored procedures you could maybe squeeze through that loophole, but your best bet is to find out what user_executable should be (maybe the same thing?) > Back to pop-before-smtp which doesn't work either, but it works better. :) :-) HTH

[Dovecot] 1.0-test75 and roadmap for v1.0
by Timo Sirainen 07 Sep '05

07 Sep '05

http://dovecot.org/test/ Keywords are finally stored in maildir filenames and listed in "dovecot-keywords" file. It should be possible to just rename 0.99.x's .customflags file to dovecot-keywords (but it can't be renamed back after modification). Also fixed another uid/sequence mixup bug with setting keywords in general (in mbox too). Fixed SHA1 checksum generation with big-endian machines (used only in passwords). I think I'll forget about the master/config rewrite for a while and leave it for Dovecot v2.0. That would mean the next release will be called 1.0-alpha1. After that there should be only bugfixes and some smaller features and optimizations left. I looked through my TODO and found the following missing features / optimizations that pretty much have to be done before v1.0. Anything important missing? - keywords: - add some limits to how many there can be - send FLAGS/PERMANENTFLAGS untagged replies when they change (required by IMAP RFC) - remove unused keywords from keyword list? (only when adding new ones) - mail cache file - cache _all_ headers that are marked to be cached when headers are being parsed, not just the ones client is requesting at that time. - compression should drop fields with last_used < (latest_mail_index_date - month) - when parsing mbox or saving message, parse the mail through index-mail so things gets saved into cache immediately - mbox - when we're updating flags with lazy writing, we're still parsing the mbox, just not writing to it! - always add empty line after mail. - make the parser require it too? syncing should make sure there always exists two LFs at end of file. raw-mbox-stream should make sure the last message ends with LF even if it doesn't exist in the file - COPY doesn't work to same mailbox (lock assert crash) - keep mbox lock for two extra seconds after sync to make sure we notice changes made by other mbox writer software - maildir - hardlink copying doesn't update indexes (does it even work?) - deliver needs quota integration somehow so it returns out-of-quota failure as fatal instead of temporary Probably after v1.0: - Full NFS support - Try to handle out-of-quota/disk space situations well

[Dovecot] 1.0.alpha1: Namespaces
by Wolfram Schlich 06 Sep '05

06 Sep '05

Hi, I'm currently using 1.0.alpha1 without luck regarding a namespace issue. Maybe it's a general understanding problem on my side, but let's see :-) I would like to have my mail stored in Maildir format below ~/.maildir/, which works fine so far. I want any (sub)folders to be created like this: ~/.maildir/ /cur /new /tmp /.Folder/ /cur /new /tmp /.Subfolder/ /cur /new /tmp BUT ;) Dovecot seems to disregard my namespace settings: --8<--[ /etc/dovecot.conf ]--8<-- default_mail_env = maildir:~/.maildir:INDEX=MEMORY namespace private { separator = / # prefix = # location = maildir:~/.maildir inbox = yes hidden = no } --8<-- Every new (sub)folder I create is stored as ~/.maildir/.Folder resp. ~/.maildir/.Folder.Subfolder in the filesystem. Are namespaces the right way? Is it possible at all? Thanks in advance. -- Wolfram Schlich

[Dovecot] upgrading: should I and what will change?
by Joshua Paine 06 Sep '05

06 Sep '05

I've been running dovecot 0.99.11 with postfix and postgresql in a production environment with about 25 real users and a couple hundred aliases split over a few domains for nearly a year now. No problems of any kind that I have noticed. Should I upgrade to the latest dovecot? What changes, if any, will I have to make? I've looked through the archives for a couple months without seeing much, and I don't see anything specific in the docs about upgrading. -Joshua <><

[Dovecot] how to migrate from one server to another?
by Bram Mertens 06 Sep '05

06 Sep '05

Hi I have purchased and installed a new PC and would like to transfer my mail (in Maildir format) to it. Are there any precautions I must take before copying the mail over? I will disable mail delivery temporarily so no new mail gets written to disk but I don't know if dovecot has to be stopped before copying/editing mail for backup or migrating purposes. Anything else I must pay attention to? TIA Bram

[Dovecot] dovecot + openwebmail
by Peter McEvoy 05 Sep '05

05 Sep '05

Hi, I'm trying to add some sanity to a badly thought out mail system that, for various reasons, cant be fixed from the bottom up at this moment in time. The system is debian sarge, exim 4.5, doing virtual domains and delivering into mboxes in /var/spool/virtual/$domain/$user , there is webmail access and this allows user to create folders in (dont shoot me!) /etc/openwebmail/users/$domain/$username/mail/ , the files in this directory appear to be mboxes in that each mail begins with a From: line, the naming of these files is completely arbitrary. Im trying to add imap access that would ideally give users access to the mail in /var , and also in the openwebmail dirs, though the latter is not essential, just desirable. All mails are owned by user mail. I've installed dovecot-imapd version 0.99.14-1, but if this doesnt have the namespace additions from version 1.0-test, I can easily install that. Reading the wiki, it seems I can achieve this with namespaces, something like namespace private { separator = / inbox = yes prefix = location = mbox:/etc/openwebmail/users/%d/%u/mail:INBOX=/var/spool/virtual/%d/%u } But, Im not quite sure where this would go in the config file, going by the example config you can just shoehorn them into the middle of the file, but I'm not 100% sure... I had been trying to use things like.. default_mail_env = mbox:/var/folders/%d/%u:INBOX=/var/spool/virtual/%d/%u:INDEX=/var/indexes/%d/%n Having created the necessary folders in /var , but I didnt have much success (the authentication part worked straight away using my passwd file), And having read more and been told about namespaces on the irc channel, it seemed like I should go that way anyway. If anyone could give me a steer in the right direction, or even tell me i'm wasting my time (tho dont bother telling me how much better maildir etc is, i know!) Thanks for your time. -- Pete

[Dovecot] dovecot and communitgate (stalker)
by tyco 05 Sep '05

05 Sep '05

hi there, i am totally new to dovecot and use communigate pro stalker.com as my mailserver. everything in communigate is fine. the only problem i do have is imap speed. i just got a login at a dovecot server and i must say WOW its so fast amazing. since communigate does not support indexing on mdir direcotries i need to find a solution. so i am wondering if it would be possible to use dovecot imap server on top of communigate as an imap server? i know that this would not work for special cgp features like shared mailboxes. etc.... thnax christof

[Dovecot] Dovecot 1.0 and ldap; does this combination works?
by Vedran Furac 05 Sep '05

05 Sep '05

Hi! After upgrading from dovecot 0.9.14 to 1.0 crashes immediately after starting when using ldap as userdb and passdb. You can find more information here: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=320388 I'm confused with two users: login_user and auth_user. Witch of them has to be in ldap? If anyone here has a working dovecot+ldap configuration, could he show me his configuration? Regards Vedran

[Dovecot] Dovecot-LDA: Development questions
by Steffen Kaiser 05 Sep '05

05 Sep '05

Hello, I'm tinkering with Dovecot-LDA in order to achieve: + Better intergration into sendmail, and + tweaking its way to act on errors. Attached patch is a "brainstorming" like suggestion: a) when sendmail is dropping a message, it spawns the LDA, captures stderr/stdout and, if the LDA returns an exit code != 0, generates either a DSN or, when EX_TEMPFAIL, queues the mail. Hence, it is not necessary to have mail_send_rejection() to spawn another sendmail instance. The attached patch suggest to introduce an "operation_mode", in which Dovecot-LDA behaves differently for different environments. b) Some errors, like when spooling the message into the users folders fails, because the user is out of quota, one should prefer tempfailing the message, rather than a permanent error. Attached patch includes an option "-f", which has main() to return EX_TEMPFAIL. This is the way maildrop is acting, BTW. === Sendmail supports "account+detail" syntax out-of-the-box; that is for recipient matching only the portion left of the plus-sign is significant, the trailing portion may be used by the LDA as a hint to spool the message. Usually the information is passed via command line to the LDA. The libsieve seems to already support this notation, see tokens DETAIL, subaddress, :detail and the README file: Derrick Brashear (shadow+sieve@andrew...) Did somebody used or have some idea how to make use of the "+detail" stuff of libsieve? Basically the main problem in my opinion is what to query, because the information (final physical mailbox and/or owner) one can query is neither a header nor an envelope information (besides that the envelope information is not available to the LDA anyway). Consider a BCC to one recipient that expands to numerous maildrops, then the maildrop of actual delivery attempt can not be derived from neither the envelope nor the header information. The only way to integrate the +detail stuff into Dovecot-LDA seems to be when "keep" is performed (or no Sieve script is present). Then one could spool the message into folder "detail", if it already exists -- one should be allow other people to create mailboxes ;-) This is no action of the Sieve library, but of the LDA calling sieve. The Wiki mentions in the section about to setup exim: envelope_to_add What's this setting is doing? In src/sieve-cmu.c, static int getenvelope, there is: } else if (!strcasecmp(field, "to")) { *contents = m->temp; m->temp[0] = /*FIXME:msg_getrcptall(m, m->cur_rcpt)*/m->authuser; m->temp[1] = NULL; return SIEVE_OK; So it seems appropriate to tweak dovecot_sieve_run() into: mdata.authuser = username; mdata.recipient = detail_on_commandline ? concat(username, "+", detail_on_commandline) : username ; Or better: Have the complete recipient passed via command line option? and alter getenvelope(): m->temp[0] = m->recipient; I think this tweaks would be better than have the "-d" option support the plus-syntax. === Currently, the compiled Sieve script is placed into the same directory the script is located itself. How about to _always_ file the compiled script into [CONTROLDIR]/.dovecot.sievec? That would come over the problem with the system-wide default sieve script. Otherwise: The README mentions a test application and I found a sievec and sieved application (Sieve compile / decompiler) I presume. I can not just run "make sievec" to have it compile, does somebody played around with the Sieve stuff in LDA? Regards, -- Steffen Kaiser

[Dovecot] 1.0a1 Coredumps / errors when moving multiple
by Gregory Bond 05 Sep '05

05 Sep '05

I've just tried upgrading 1.0t51 to 1.0a1 and it has been........ difficult. I've been getting logs of Sig11s and other errors, and have trouble tracking them down. Main problem seems to be with moving / copying messages. One at a time works (mostly), multiple will coredump the imap process (not yet managed to get a proper core out though...) I'm using imap & Maildir, maildir on NFS & Indexes on UFS, Solaris 8. Server is postfix / procmail (delivering pre-sorted into various Maildir folders) and Dovecot 1.0a1. Client is thunderbird on OS/X. If I turn off mbox_copy_with_hardlinks, then instead of a coredump I get a hang and an error message: > IMAP(gnb): Maildir /home/gnb/Maildir sync: UID inserted in the middle > of mailbox (3871 > 3870, file = 1125740849.23189_0.lenford:2,Saa) This is after I've removed all the cache/index files and even all the dovecot-uid files.... I'm back on 1.0t51 for now, but could have another crack at this if there are any hints.

[Dovecot] Dovecot logging
by Black Vette 05 Sep '05

05 Sep '05

Fedora Core 4 dovecot-0.99.14-4.fc4 I'm trying to diagnose some mail issues. I do not believe Dovecot is the problem. If I could see the Dovecot logs, it might be helpful in resolving my issue. In /etc/dovecot.conf I have tried to set the following: log_path = /var/log/dovecot.log info_log_path = /var/log/dovecot.log I have 'touch /var/log/dovecot.log'. When I try to restart dovecot 'service dovecot restart', it fails and I'm not able to see the reason why it is failing. Where am I going wrong getting this working? Also, are there various debug levels? I saw 'debug' mentioned on the list, but I was unable to see anything about it in the config file. Thanks, Mike __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

Re: [Dovecot] qpopper UIDLs and migrating to dovecot/maildir
by Paul Vatta 05 Sep '05

05 Sep '05

Hi Chris, We migrated to Dovecot from Qpopper/UW-IMAP in July. We previously looked at altering the Dovecot code, client-side duplicate email cleanup utilities (for Eudora), and enforcing "download-then-delete from the server" prior to the migration. We got around the "downloading of previously downloaded emails" problem by moving all previously downloaded emails to a new folder called "ConvertedMail" during the conversion process from mbox (Qpopper) to maildir. This assumes you're going to maildir though. The benefit in this is that the POP client only retrieves email from th inbox folder, and after conversion, this will mean only new emails. If the POP client's previous download of older email dissappeared (for whatever reason), a Web Mail client accessing the mailstore via IMAP would allow access to the ConvertedMail folder. Regards, Paul

[Dovecot] login: Missing Protocol from server name 'imap'
by Phil Bettinson 04 Sep '05

04 Sep '05

Hello All (possibly again) I did send a messge earlier, but it may have been eaten by the mail system. I've now managed to get dovecot started, and I'm now getting "Missing protocol from server name 'imap'" This is somewhat confusing. Does it mean that I have somewhere called my server imap? or is it talking about it missing a protocol called imap? if it's meant to be "missing protocol imap definition" or somesuch, I have filled that out, but can't for the life of me figure out what the error message is actually trying to tell me! I'm running dovecot alpha1 on RedHat as3. I have the feeling I've been staring at the problem for too long, and somone will just say "have you tried this!", but it's worth a shot. Thanks in advance Phil

[Dovecot] qpopper UIDLs and migrating to dovecot/maildir
by grant beattie 04 Sep '05

04 Sep '05

hi all, I am hoping to convert a 350K user qpopper installation using mbox to dovecot and maildir (pop3 only). many of the users "leave mail on server", and qpopper's UIDL format isn't (yet) supported by dovecot. since the UIDLs have been written by qpoppper to the existing mbox files (and will be preserved when the mboxes are converted to maildir) it would be possible to do this seamlessly if dovecot could read the UIDLs from the messages and populate the index files as needed. is anything like this already possible? it doesn't matter what UIDLs new messages get, since they would never have been downloaded by the user via qpopper. any ideas would be appreciated. grant.

[Dovecot] Purge / Delete Problem using IMAP
by A Ve 03 Sep '05

03 Sep '05

Hi, I am using dovecot 0.99.14 RPM on a Fedore Core 4 Server. Everything was running fine for weeks (IMAP), and 2 days ago I was not able to delete/purge any Mail in INBOX. I am using Outlook 2003 as an IMAP-Client. I tried to delete/purge the Inbox with other mail-clients (Mozilla Thunderbird, Mulberry) too, same effect: I can read mail, I can copy them by drag-n-drop to a local Client-Folder (eg: Outlook) , but I can delete them. Strange enough, the mails are marked as read, but when I login again, all Mail are marked as new/unread ! When I log to the node, and start mutt (which is using the spool-file /var/spool/mail/username), then I am able to read-n-delete all Mails... The File Permisson of the File: 755, Owner: Username, Group: Mail. Did I miss something ? How can this stop working from one day to another ? I seems to me, like the INBOX is not writable to me ... From the UNIX Side, it is ... :-/ Any Comment/Feedback would be helpfull. This is really strange. Regards, AVE.

[Dovecot] string expansion *in* dovecot config?
by OpenMacNews 03 Sep '05

03 Sep '05

hi all, is it possible to define/use 'MACROS' (string expansion, ala Exim) in dovecot's config file? specifically, e.g. -- rather than: login_executable = /some/crazy/path/to/dovecot/libexec/dovecot/imap-login i'd LIKE to do something like MY_PATH = /some/crazy/path/to login_executable = MY_PATH/dovecot/libexec/dovecot/imap-login i'm reading the wiki docs, and it's just not obvious to me ... thanks! richard

[Dovecot] Weird internaldate behavior with 1.0-test80 and mbox folder
by Jon Roma 03 Sep '05

03 Sep '05

Has anyone else encountered weird date behavior with mbox-style folders? I am nearly ready to bite the bullet and convert my UW imap hierarchy (which is in mbx format) to Dovecot. In so doing, I need to convert each UW-specific mbx-format mailboxes to the more portable mbox format, which Dovecot can read. (This is done with the 'mbxcvt' utility that's part of UW.) I am then planning to copy those mbox-format folders into a staging area in a directory I've defined to Dovecot as a mbox-format namespace. The plan was then to use my normal GUI to reorganize my old data and copy it into proper maildir folders into Dovecot's default namespace. Since I'm naturally paranoid, I did a dry run of a couple folders first and discovered a rather strange anomaly -- all the mail in the converted folder is displayed by Dovecot with a timestamp exactly 200 minutes (3 hours 20 minutes) into the future! Investigating this via telneting to the respective IMAP ports shows that UW imapd shows the correct timestamp both in the original mbx-format folder and the converted mbox-format folder -- so it appears that Dovecot is skewing the time. This doesn't look like a timezone issue since 200 minutes ahead from CST6CDT would be a pretty strange timezone -- not even Newfoundland has this odd a TZ value! :) (For the curious, Newfoundland is a Canadian province whose time zone is TZ=NST3:30NDT, therefore being a half-hour "off" from the rest of North America.) I have distilled this into a degenerate case of a single folder with a single message and can reproduce. As mentioned, I am running 1.0-test80. My platform is AIX 5.1. I created the test by sending a message to myself using date | mail -s "Test at $(date)" roma(a)uiuc.edu and using my MUA (Mulberry) to file it into the test folder, which defaults to mbx format in UW's namespace. Here's what UW shows when I select/fetch the "original" message: * namespace * NAMESPACE (("" "/")("#mhinbox" NIL)("#mh/" "/")) (("~" "/")) (("#shared/" "/")("#ftp/" "/")("#news." ".")("#public/" "/")) * OK NAMESPACE completed * select "~/Test" * 1 EXISTS * 0 RECENT * OK [UIDVALIDITY 1124811965] UID validity status * OK [UIDNEXT 3] Predicted next UID * FLAGS (\Answered \Flagged \Deleted \Draft \Seen) * OK [PERMANENTFLAGS (\* \Answered \Flagged \Deleted \Draft \Seen)] Permanent flags * OK [READ-WRITE] SELECT completed * fetch 1 internaldate * 1 FETCH (INTERNALDATE "23-Aug-2005 11:16:37 -0500") * OK FETCH completed * fetch 1 envelope * 1 FETCH (ENVELOPE ("Tue, 23 Aug 2005 11:16:30 -0500" "Test at Tue Aug 23 11:16:29 CDT 2005" (("Jon Roma" NIL "roma" "zippy.cso.uiuc.edu")) (("Jon Roma" NIL "roma" "zippy.cso.uiuc.edu")) (("Jon Roma" NIL "roma" "zippy.cso.uiuc.edu")) ((NIL NIL "roma" "uiuc.edu")) NIL NIL NIL "<200508231616.j7NGGUrc022618(a)zippy.cso.uiuc.edu>")) * OK FETCH completed Next I use the UW 'mbxcvt' to convert the folder, leaving it in mbox format in a different folder (~/Test-mbox) -- still in UW's namespace. Here's what the telnet connection shows: * namespace * NAMESPACE (("" "/")("#mhinbox" NIL)("#mh/" "/")) (("~" "/")) (("#shared/" "/")("#ftp/" "/")("#news."

Notice the "internaldate" response. Dovecot reports the correct time zone, but the internaldate value is 200 minutes ahead of what it should be!!! This is an interesting mystery; I seem to be living three hours and 20 minutes in the future. I've attached the entire contents of the mbox-style mailbox that Dovecot misinterprets.

[Dovecot] (no subject)
by Phillip Needham 02 Sep '05

02 Sep '05

I am trying to get away from courier imap because it is flaky the way it uses FAM (or gamin in my case), and the developers seem to have a chip on their collective shoulder, and it is too complex. I found dovecot because it is ships with CentOS 4 (ie Red Hat Enterprise 4). It looks like just what I need: simple, fast. But I can't use it! I can't authenticate. If any of these statements were untrue, I would use it happily: o it doesn't support simple bind authentication against LDAP o I don't want to make passwords readable, and this version (0.99.14) doesn't support SSHA anyway o it won't talk to the saslauthd I already have configured o I can't find how to implement a new auth module for dovecot I am wondering why, in the quest to fill a niche with a simple, fast, secure IMAP server, the authors felt the need to re-implement a robust and well-tested infrastructure (saslauthd) with a less-featureful and untested one?

[Dovecot] Dovecot imap with Postfix and using Thunderbird as client
by Ben Ware 02 Sep '05

02 Sep '05

Hi, I just recently installed dovecot, and I am having the following problem: If I send an email to my account on this new machine, I can log in via SSH and use the unix mail command, and instantly my email is visible. If I turn on Thunderbird, it will show my new message. If Thunderbird was already on and had already checked the mailbox, even if I click on get new mail for that specific mailbox, the new mail does not show up until I restart thunderbird. Is there something that I have set wrong in the config files that is preventing the IMAP part of dovecot from refreshing the messages quickly for me to see? I dont see anything in the log files at all except for it showing me logging in. Thanks, Ben

[Dovecot] 'Bind'-method authentication for LDAP
by Phillip Needham 02 Sep '05

02 Sep '05

Has there been any thought given to implementing authentication via an LDAP 'bind', rather than by a password lookup and hash comparison? doing a bind would obviate the need to make the passwords readable by the dovecot process and would lend itself to improved security.

Re: [Dovecot] Oddities with Debian unstable dovecot

whaooo that is interesting, Thank you so much for the explanation. I guess my choice now is to go with maildir as Blairpoint out because I am running in single host mode. Probably in the future I will run a big enough enviroment as a cluster data center them I will op for mbox.

Thanks. I'd say it depends, I'm working with clustered filesystems in SAN environments where mbox is significantly faster than maildir since single mbox file generates much less overhead in form of distributed file locking accross cluster nodes. On single host systems with good file system I'd probably go with maildir. Maybe someday I'll manage to do some benchmarking between mbox and maildir with Dovecot. -- Tomi Hakala
