Hi, I am mounting a server of email with the Dovecot as MUA, i would like to restrict the access to imap and ipop to one determined range of IP. As I configure this in dovecot.conf, I did not understand the functioning of listen = * or [: ] Thanks a lot, Clovis -- Clóvis Tristão -------------------:-oo)---- Seja Legal, use GNU/Linux ----------------------------------------

[Dovecot] Tools to analyze status/stats?
by wolff 07 Dec '05

07 Dec '05

Hello, I recently installed dovecot on a server running Debian. I only have 10 users, but we probably have 6Gig of email between us. Things were working flawlessly for a couple of weeks, and I'm still getting email, but the last few days we are getting fewer emails that we typically do. So although things seem to be working well, everyone is suspicious something is wrong due to the lack of email volume. Is there a size limit that dovecot can manage? Are there any admin tools to get status messages for dovecot? Are there any reporting tools to show how many messages are processed/managed by dovecot? Thanks!!

[Dovecot] 1.0alpha4: pop3_reuse_xuidl patch
by grant beattie 06 Dec '05

06 Dec '05

hi all, this is needed to make the pop3_reuse_xuidl option work in 1.0alpha4. I am using maildir and I noticed that for each message which doesn't have an indexed X-UIDL header, the entire message is read from disk. as this is reading only headers, it is probably reasonable to stop reading at the end of the headers. it would also be neat if dovecot could be configured to only try reading X-UIDL headers from messages if the mailbox indexes don't exist, since I guess it would be common to want to preserve existing X-UIDLs but not bother for new messages (perhaps some mtime comparison, or something). opinions? I haven't looked at the source enough yet to be able to do this, but these two optimizations would vastly reduce the amount of disk IO as a result of using this option. grant.

[Dovecot] Struggling with namespaces...
by Kev Latimer 06 Dec '05

06 Dec '05

Hi all, I've been using dovecot 0.99x as a basic POP3/IMAP server at a couple of sites for a few months now and am very happy with it's simplicity, stability and performance, especially over the rather 'clunky' courier and the mammoth cyrus. I'm building up a top level mail server for our organisation and am desperate to use dovecot in there but I'm really struggling with using namespaces to create some shared maildirs - note that in this case I'm using the 1.0alpha4 debian packages that recently made it into 'etch'. I have very simple requirements here - I just want to be able to have some common folders subscribable by certain users, for my testing an announcements folder accessible by all and an archive folder I want to place some restrictions on. Whenever someone needs access to someone elses folder (ie. holiday watch), symlinking should be sufficient. I can start up dovecot, log in as a user (I authenticate against LDAP btw), see the directories specified in my namespace directives be created but I can't subscribe to anything. Squirrelmail gives an error stating "[TRYCREATE] Mailbox doesn't exist: archives" while Thunderbird shows the folder names in grey and refuses to subscribe. Am I missing the point of namespaces or have I failed to create something in the folders to get them to play? I read something about a dovecot-shared file but I think this is a 0.99 thing, although I tried creating the file with the permissions I wanted applied to the folder and it didn't do anything... I did notice that when the folders are created, they are created owned by the first user logged in. I have tried chmod'ing them to 777 to see if it makes a difference, but alas, no. The relevant bit of dovecot.conf is: namespace private { separator = / #prefix = #location = inbox = yes #hidden = yes } namespace public { separator = / prefix = announcements/ location = maildir:/var/mail/announcements/Maildir } namespace shared { separator = / prefix = archives/ location = maildir:/var/mail/archives/Maildir } I'm sure I'm just being picky, but a better explanation of namespaces in the docs might be in order, maybe with some examples. If I get this sussed out, I'll put one in the wiki ;) Any help much appreciated! Kev

[Dovecot] 1.0.alpha4 process creation wierdness
by Mark Rosenstand 06 Dec '05

06 Dec '05

Hi list! I'm a little confused. I have set "login_process_per_connection = yes" and "login_processes_count = 1", and this is how my pstree looks when nobody is connected: dovecot -,- dovecot-auth `- imap-login However, when I connect with a client it looks like this: dovecot -,- dovecot-auth |- imap `- 2*[imap-login] I would expect it to only have one imap-login running. Anyway, when I disconnect the client, the imap process exits but imap-login keeps running: dovecot -,- dovecot-auth `- 2*[imap-login] This is when it gets really wierd. When I connect a client again, my pstree looks like I would have expected it to on my first connect: dovecot -,- dovecot-auth |- imap `- imap-login If I re-connect, we start over again (i.e. dovecot-auth, imap, 2 * imap-login). Anybody got a clue what's going on? :-) -- .-. Mark Rosenstand (-.) oo| cc ) /`'\ (+45) 255 31337 3-n-( (\_;/) mark(a)borkware.net _(|/`->

[Dovecot] Feature/bug starting from xinetd
by Geoffrey S. Mendelson 06 Dec '05

06 Dec '05

Hi, I hate to have my first post be a bug, but this drove me crazy for a while. I compiled the latest version from source and followed the instalation instructions. I then copied the xinetd.d entries from the Wiki and proceded to test. No matter what I did I could not log on. I found that while I was editing /usr/local/etc/dovecot.conf, nothing was hapening. I then started it manualy and found several errors in my editing. :-) After fixing the errors and getting it to work properly, I went back to running it from xinetd. It would not allow me to log on, nor would it use any of the loging options I set. After making a symlink from /usr/local/etc/dovecot.conf to /etc/dovecot.conf, it worked perfectly. My suggestions: 1. Change the Wiki to point out the difference in the config file location. 2. Change the inetd version to default to /usr/local/etc. 3. Add (and/or document) an option to the inetd version to specify config file location. Thanks, Geoff. ( A very happy Dovecot user, thanks for a good product). -- Geoffrey S.

[Dovecot] New Install Assistance
by Cliff Hayes 06 Dec '05

06 Dec '05

Hello, I built a Fedora 4 sendmail server to replace our old one. I wanted to try the stock Dovecot popper (we currently use pop3d). I tried implementing Dovecot this morning and failed. All I want to use is the POP portion (no IMAP). From what I could find on the Internet, all I had to do is change dovecot.conf protocols line to read like this: protocols = pop3 Apparently, that wasn't enough. Here are the errors I saw in maillog: Oct 31 07:54:23 sendmail dovecot: child 25511 (pop3) returned error 89 Oct 31 07:54:24 sendmail pop3(cliffhayes): mbox: Can't create root IMAP folder /home/cliffhayes/mail: Permission denied Oct 31 07:54:24 sendmail pop3(cliffhayes): MAIL environment missing and autodetection failed (home /home/cliffhayes) Now, I did find out that I had a permissions problem with /var/spool/mail (I had done an SCP of all our users to var/spool/mail on new box). All user mailboxes had root/root as user/group. I know how to fix that for next time, but why is it trying to use a home directory (we don't use those)? And what MAIL environment is missing? Do I need to mess with the following settings: # default_mail_env = maildir:/var/mail/%1u/%u/Maildir # default_mail_env = mbox:~/mail/:INBOX=/var/mail/%u # default_mail_env = mbox:/var/mail/%d/%n/:INDEX=/var/indexes/%d/%n Thanks, Cliff

[Dovecot] Dovecot and loadbalancer
by Cyril Feraudet 06 Dec '05

06 Dec '05

Hi all, I've 4 servers with dovecot and ldap authentication behind a loadbalancer (Alteon). To connect to dovecot, client need to use a vip of the loadbalancer. To connect to the ldap server, dovecot need to use the loadbalancer cause there are several ldap server. The loadbalancer close a connection without activity during 30mn Dovecot lauch several authentication process who have a connection to the ldap server each. Each client (user) have several imap connection to dovecot. I've 2 problemes : - If a client (thunderbird for ex.) don't use a connection during 30mn, the loadbalancer delete this connection from his connection table and the client seem not able to correctly reopen another - If a dovecot authentication proccess want to request ldap but haven't do it in the last 30mn, it fail an say that the authentification fail. Somebody have already use dovecot in a redundent environnement ? Have you an idea to solve these problems Thanks, Cyril Feraudet

[Dovecot] New mailbox format
by Timo Sirainen 06 Dec '05

06 Dec '05

I've been doing some thinking on a new better mailbox format that'd be faster than mbox and maildir for most common uses. Comments welcome. It won't come to Dovecot v1.0, but I'll probably create another branch to Dovecot CVS where I'll start implementing it and some other possibly destabilizing changes. 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. This format is mostly designed to work nicely with separate index files such as Dovecot has. The flags are stored in the mailbox files mostly as a backup in case the index gets lost or corrupted. 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). When the file is opened, it must be shared locked with flock(). Expunging mails requires exclusive flock(), so expunges can't happen while someone is still reading the file. Mails can however be marked with expunged-flag, and such mails should be treated as if they are already expunged. Expunged flag must not be removed. If the mail for some reason is wanted to be un-expunged, it must be copied as a new mail with new UID to the mailbox. Modifying flags doesn't require any locks. You'll simply write over those flags you wish to change. That's why each flag takes one byte. Safest way to expunge is to copy 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. Alternative way to expunge is to just move the data over the expunged mails and fruncate() at the end. No index file updates necessary. This is more filesystem quota friendly, but if the expunging gets aborted in the middle it will corrupt the mails. Appending mails can be done by either locking existing file with a dotlock and appending to it, or creating a new file. If appending to existing file, also flock() it so expunging won't happen in the middle of append. If appending to new file, create it with .lock suffix and then check that the file without .lock wasn't already just created. 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. Keywords file ------------- Named "index.keywords". This contains mappings between keyword numbers and names. TODO: may be problematic with lockless flag writes.. 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) One problem with nightly expunging is how to expunge mails if the file is still locked by some process. Forced shutdowns may be annoying to users and can be difficult to implement.. Alternative locking strategy ---------------------------- The locking strategy as described above is optimized for high concurrency: Only if mail file is in the middle of being expunged, we're waiting on locks. With appending we may be waiting for existing appends to finish if we don't wish to create a new file for some reason. Other than those, reading and flag updating are completely lockless. The two downsides to this are: 1. flock() isn't available everywhere. It could however be replaced with fcntl() if that's available. NFS may not have either. 2. Expunges can't happen while multiple processes are accessing the mailbox at a same time. This may be a problem if the mailbox never has less than two processes accessing it. The alternative to flock()ing would be to simply handle unexpected end-of-file reads as a sign of expunge, which would require re-reading index file to see where the mails went (or if they were really expunged). This has two problems however. One is that flag writes couldn't catch expunges without locking, and another is that if you've already sent half a mail to IMAP client, you have no other choice than to disconnect the client if you can't send the rest of the mail. It might be worth it optionally. Especially for NFS people. Then you'd basically have the dotlock file that locks appends, expunges and flag updates. Reading would still be lockless. Also for the best performance the mail flags could be stored only in Dovecot's index files. In that case there's no need to update flags and the only downside with this locking strategy would be the potential disconnections, which probably aren't all that bad. 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] Segfault when using multiple servers
by Marc Maurer 06 Dec '05

06 Dec '05

Should it be possible to run multiple dovecot servers on the same mailboxes (Maildir in my case)? I've a setup where 2 dovecot 0.99.13 servers write to the same mailboxes, which dovecot apparently does not like too much. Example (using imap): - Login with mail client on server1 - Login with webmail on server2 - Delete a mail using webmail on server2 - Hit send/receive in the mail client Result: server1 segfaults. Is such a setup, which is basically a loadbalancing setup, allowed at all by dovecot? Cheers, Marc

[Dovecot] mbox separators ignored
by Kenneth Porter 06 Dec '05

06 Dec '05

Using dovecot-0.99.13-4.FC2 I grabbed a bunch of Mailman archive files from the Weather mailing list here: <http://www.buoy.com/pipermail/weather/> I gunzipped the older ones, then concatenated them all in correct order to create one big mbox file. I dropped it into my ~/mail folder and started my IMAP client (Mulberry) and opened the new Weather folder. It shows one gargantuan concatenated message, instead of lots of more reasonable-sized ones. The messages appear to be properly separated by "<linefeed><linefeed>From<space>". Why doesn't dovecot parse them into separate messages? I double-checked and removed any header lines with Content-Length, X-UID, X-IMAPbase, and X-Keywords. So this should look like a new mbox file with new content delivered by procmail. What's confusing dovecot?

[Dovecot] Virtual domain support using more than one MySQL database
by Dragiša Durić 04 Dec '05

04 Dec '05

For historical reasons I am stuck with situation where hosted domain users have their Mailbox info in mysql enabled vpopmail and our ISP's users have their info in nss_mysql. While I can easily move my users from vpopmail's mysql database to something more "native" to Dovecot, I see no problem to configure Dovecot, as I've already configured Postfix, to use this database directly and access mailboxes without problem. And I would not like to make separate auth database for ISP's users, as I don't like to have two watches when one suffice. Under courier-imap, I've configured my vpopmail domains to authenticate using it's vchkpw module, and mysql was left to me to be configured to use nss_mysql. It works well. Is it possible under Dovecot, and how? Is it possible to to MySQL auth using two different databases? It would be the best. TIA, dd

[Dovecot] Dovecot strange behaviors on Solaris
by Mario Nigrovic-rvvk40 03 Dec '05

03 Dec '05

Folks - I've been using Dovecot for some time now, but have only recently upgraded to 1.0alpha4. I'm struggling to get my configuration right and I'm seeing some truly bizarre issues. My Setup: Solaris 2.8 / Thunderbird / Procmail / Dovecot 1.0alpha4 My mail setup is only for me, so Dovecot runs at an odd port and under my userID. All my mail is in my home directory, which is on NFS (NetApp). The main mail receiver is a different machine which mounts my home directory. Typical entry from .procmailrc: :0 * ^(From|To|CC):.*@.*\<si2.org Maildir/.SI2/ Highlights from dovecot.conf: #default_mail_env = maildir:%h/.mail/Maildir:INDEX=/var/tmp/mario/dovecot default_mail_env = maildir:%h/.mail/Maildir:INDEX=MEMORY mmap_disable = yes #lock_method = flock lock_method = fcntl #lock_method = dotlock protocol imap { listen = *:2143 } auth_worker_max_count = 0 auth default { mechanisms = plain userdb passwd { } } When I run as above (INDEX=MEMORY), I have access to all my mail, but I'm seeing literally thousands of .nfs files created all throughout my .mail/Maildir directories, and Thunderbird periodically locks up. As the filesystem fills with useless .nfs files (I deleted 10000 from ONE mailbox directory this morning), everything gets really, really slow, and I suspect this contributes to Thunder bird's problem. But, if I run with the INDEX on a local disk, many mailboxes will not load (the most critical ones, of course...), but also some do. My inbox will list messages, but cannot display any. Others won't even list messages. I'm at a total loss how to proceed, here. I've tried everything I can think of to debug what's going on, but have gotten nowhere (well, I did discover the whole lock_method=fcntl trick). I've tried enabling rawlog, but am just not familiar enough with IMAP to get help from those logs. Here's what's happening in a typical mailbox: % pwd /home/mario/.mail/Maildir/.SI2 % ls -al total 544 drwx--S--- 5 rvvk40 lowv 425984 Dec 2 14:42 ./ drwx--S--- 64 rvvk40 lowv 16384 Dec 2 14:43 ../ -rw------- 1 rvvk40 lowv 15 Nov 16 07:16 .customflags -rw------- 1 rvvk40 lowv 24 Dec 2 14:38 .nfs00986 -rw------- 1 rvvk40 lowv 24 Dec 2 14:40 .nfs08986 -rw------- 1 rvvk40 lowv 312 Dec 2 14:11 .nfs16686 -rw------- 1 rvvk40 lowv 24 Dec 2 14:32 .nfs1A886 -- 40+ deleted here for brevity -- -rw------- 1 rvvk40 lowv 24 Dec 2 14:39 .nfsE3986 -rw------- 1 rvvk40 lowv 312 Dec 2 14:38 .nfsEF886 -rw------- 1 rvvk40 lowv 24 Dec 2 14:26 .nfsF3886 -rw------- 1 rvvk40 lowv 312 Dec 2 14:32 .nfsF9886 -rw------- 1 rvvk40 lowv 312 Dec 2 14:17 .nfsFF686 drwx--S--- 2 rvvk40 lowv 4096 Dec 2 07:58 cur/ drwx--S--- 2 rvvk40 lowv 4096 Dec 2 07:58 new/ drwx--S--- 2 rvvk40 lowv 4096 Dec 2 07:58 tmp/ % pwd /home/mario/.mail/Maildir/.SI2 Help!

[Dovecot] Silly newbie questions...
by Michael Segel 03 Dec '05

03 Dec '05

Hi, I'm relatively new to dovecot, less than 48 hours, and I've ran in to a few bugs in the installation/configuration process. Here's my set up. I have my own domain. Within the domain, I have a couple of Linux boxes. So I control both my primary and secondary mail servers. My Linux boxes are a mixture of SuSE 9.2, 9.3 and 10.0 (All based on age of the hardware.) I'd like to use Postfix for my MTA, which I have up and running, but I'd also like to add an IMAP server (hence dovecot) so I can get my mail from any of my PCs and my blackberry.) On my main mail server, I have KDE running and it uses ~/Mail/inbox/(cur,new,...) When I tried to use KDE on my other Linux server, I got it to authenticate and I could see the folders, but I couldn't see any of the mail. (Its all in cur subdirectory.) Now I did notice that when Postfix gets a mail message, its placed in /var/spool/mail/msegel which would imply its using an mbox format. So what am I missing? TIA! -Mike -- Michael Segel Principal MSCC

[Dovecot] dovecot on os x

[Dovecot] corrupt attachments
by Brian Thompson 02 Dec '05

02 Dec '05

Not sure if this has already been covered, but any pointers or suggestions would be greatly appreciated. We just realized last night that dovecot-stable seems to be corrupting the attachments within users' inboxes. In an attempt to resolve the problem, we upgraded the mail server here to Dovecot 1.0alpha4 but it didn't help. To the best of our knowledge we didn't start experiencing this phenomena until we migrated from Solaris 8/Sparc to Solaris 10/x86 about 3 weeks ago. To be more specific: A non-corrupt attachment can be sitting within a user's mail spool (mbox format) and live there without a problem until an imap client goes to download the attachment via dovecot. At that time, dovecot seems to be stripping the last four characters from each base64 encoded ascii line within the attachment and rewriting the message within the mail spool without those characters. From then on, the attachment is permanently corrupt, even via local unix direct file access clients such as pine or elm. We've temporarily switched back to UW imapd, but users have noticed the decrease in speed - not having the indexing available. Again, any suggestions would be greatly appreciated. Thanks, Brian

[Dovecot] Multiple authentication databases and storage locations
by Odhiambo Washington 02 Dec '05

02 Dec '05

Hello Everyone, I am playing with the $subject matter using 1.0alpha4, and thanks to the archives, I lifted this one from Alexander Shikoff off and used it in my setup. auth default { mechanisms = plain user = root passdb pam { args = pop3 } passdb sql { args = /usr/local/dovecot/etc/dovecot-mysql.conf } userdb passwd { } userdb sql { args = /usr/local/dovecot/etc/dovecot-mysql.conf } } It seems to work, but I have virtual users as well as system users. System accounts have their mail stored as follows: default_mail_env = maildir:/home/%u/Maildir While virtual users have this: default_mail_env = maildir:/htdocs/virtual/spool/%d/%u/Maildir Now, virtual users can login because I have used their $default_mail_env in my configuration. I am stuck how to get system users to successfully access their e-mails. Here is the error I get: beastie# telnet 0 110 Trying 0.0.0.0... Connected to 0. Escape character is '^]'. +OK Welcome. Dovecot is Ready to serve. user wash +OK pass a_verysecret1 +OK Logged in. -ERR No INBOX for user. Connection closed by foreign host. In the log file, here is what I see: dovecot: Nov 19 23:22:11 Error: pop3(wash): mkdir(/htdocs/virtual/spool//wash/Maildir/cur) failed: Permission denied dovecot: Nov 19 23:22:11 Error: pop3(wash): mkdir(/htdocs/virtual/spool//wash/Maildir/cur) failed: Permission denied dovecot: Nov 19 23:22:11 Error: pop3(wash): Couldn't open INBOX: Internal error occurred.

[Dovecot] After restart dovecot do not serves IMAPS anymore
by Marian Hercek 02 Dec '05

02 Dec '05

I had to restart computer yesterday and now Dovecot has strange behaviour. Dovecot is running and should serve IMAPS, but client Mozilla Thunderbird cannot connect. I tried openssl s_client -connect localhost:993 and it said only CONNECTED(00000003). A time ago when everything was OK, the listing after connection was "a bit" longer than it is now. I remember there was "OK, dovecot ready" or something like that. Now, there is none. Of course in /etc/dovecot.conf: protocols = imaps imaps_listen = * ssl_disable = no So, what's the problem?

[Dovecot] Dovecot logs to syslog (other than MAIL)?
by Steve Bigley 02 Dec '05

02 Dec '05

I see in the config file where I can enable syslog, but then all logging goes to the MAIL facility. I could find no reference to changing the facility:level for syslogging. Is that implemented, or planned? I know I could just write it to a file, but I'd prefer to use syslog because then I can pipe it to a central logging server.

[Dovecot] Multiple Mailstores using 1.0alpha4
by Brian T Glenn 02 Dec '05

02 Dec '05

I am using qmail-ldap to provide virtual users to my system, but I also have some shell users on the system as well. Virtual users go into /home/vmail/mailstore/$username/ System users go into /home/$username/Maildir How can I have both of these available as inboxes in dovecot using ldap logins? Do I need to use namespaces or am i missing something with default_mail_env? Thanks, -- Brian T Glenn delink.net Internet Services

[Dovecot] Yet another silly question...

Ok, I now have Dovecot working but I'm having an issue with my start up from xinetd. I tried to follow the examples in the documentation, but why can't I just have a single entry for IMAP with just dovecot? Wouldn't this also open up the SSL and the POP3 stuff as well?

[Dovecot] Unused SQL API
by Curtis Maloney 02 Dec '05

02 Dec '05

Greetings, recently I've been writing a database driver module for Dovecot to use SQLite. It's mostly for my own use, but I do recall other people have asked for this. Firstly - Timo, I grow to love your work more and more every day. :) I have not had any trouble figuring out what is needed of the driver, even without any API documentation. However, the one part of the driver that's given me pause has turned out to most likely be unnecessary. Whilst I was trying to work out how to deal with the sql_result->get_values() call without leaking memory, it seemed an odd method to have along side the other calls. So I decided to look for where it was used, to try to understand. Only, it isn't. The _only_ point I can find in the sources that calls that method is in the Postgress SQL driver. Am I missing something? -- Curtis Maloney cmaloney(a)cardgate.net

[Dovecot] Question on moving folders
by Andy Cravens 02 Dec '05

02 Dec '05

Is there a way to move an imap subfolder up one level? I have a bad mouse and every now and then I have accidentally dragged an imap folder on top of another folder. I am unable to get the original folder back up one level. I've tried using several clients and I can't get it to work with dovecot. I keep getting a "folder already exists" message. I'm guessing dovecot still sees the original folder before it was moved. Any tips... besides getting a new mouse? -- Andy

[Dovecot] Chrooting question
by Greg Pendler 01 Dec '05

01 Dec '05

Hi, All. I've got a feeling it's a simple matter and it was discussed on this list (i've searched the archive) but still all answers i've found didn't solve this problem. We want to move from UW-IMAP to dovecot, when users INBOX is /var/mail/USER_NAME and his folders are ~USER_NAME/mail/. In addition the host is an FTP server that uses chrooting in order to prevent users from accessing files outside their home directories. Our /etc/passwd line looks like this: some_user:x:1234:123:Some User:/home/./some_user:/bin/shell When i try to check mail on this host with this user i receive the following error message: Dec 1 08:21:11 server dovecot: [ID 935345 mail.error] Invalid chroot directory '/home' (user some_user) (see valid_chroot_dirs in config file) After which comes a line with: "Internal login failure" I've tried to configure different chroot options in configuration file, but had no luck at all. Of course when i remove the "." from passwd line everything works great (except FTP:). I'm using 1.0 alpha 4 on Solaris 9. Please let me know if you have such setup and what is the exact setting i need to add to configuration. Thanks in Advance, Greg

[Dovecot] dovecot 1.0.alpha4 hangs at auth
by Mihai Secasiu 01 Dec '05

01 Dec '05

I'm using dovecot 1.0.alpha4 on a freebsd 5.3 i386 system. Dovecot is configured to use mysql authentication and I'm running mysql 5.0.15 . Everything works fine, but after a period of inactivity (20-30 minutes ) when I connect and try to authenticate it just hangs. I noticed that the dovecot-auth worker process is not running anymore... from looking at the source code I understand that the dovecot-auth worker process is actually a client that connects to the main dovecot-auth process ( the server) I restarted dovecot and I straced the auth worker process ... after 20-30 minutes it just existed here is the output of strace : gettimeofday({0, 0}, NULL) = 0 poll([{fd=5, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=4, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}], 2, 0) = 0 gettimeofday({1133138508, 221796}, {0, 0}) = 0 gettimeofday({0, 0}, NULL) = 0 poll([{fd=5, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=4, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL, revents=POLLIN}], 2, 1999) = 1 gettimeofday({1133138509, 49095}, {0, 0}) = 0 read(4, "", 478) = 0 close(4) = 0 fcntl(7, F_SETFL, O_RDWR|O_NONBLOCK) = 0 read(7, "", 8192) = 0 fcntl(7, F_SETFL, O_RDWR) = 0 write(7, "\1\0\0\0\1", 5) = -1 EPIPE (Broken pipe) shutdown(7, 2 /* send and receive */) = 0 close(7) = 0 close(3) = 0 close(5) = 0 close(6) = 0 close(-1) = -1 EBADF (Bad file descriptor) exit(0) = ? Why is the auth worker exiting if it reads 0 from fd=4 ? is it possible to make it so that it does not exit ? and in the case it exits is there a mechanism to restart it? Another question would be why read(4, "", 478) returns 0 ? this means that the server closed connection right ? why would the auth server close the connection with the auth worker ? I had a similar problem with dovecot 0.99 but there I got a "login failed" error message immediately , with 1.0alpha4 it just hangs. I also used a nightly cvs snapshot and the problem is there too. Thank you for your time Mihai Secasiu http://denixsolutions.com/

I do a : telnet localhost imap Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK dovecot ready. 1 login user pass (here is the delay) After passing a username/password, the process is like stuck for some reason. I have to killall dovecot processes and do a: service dovecot restart and it work again. I have 1.5GB left on the disk and this problem just appeared now after month of working correctly. Could it be the disk space? How can I debug the problem? Should I migrate de 1.0alpha4? Does alpha4 have a new code in the authentication phase?

[Dovecot] Not an IMAP4 Server?
by John Gray 28 Nov '05

28 Nov '05

I've been testing alpha4, and every once in a while my client (Thunderbird 1.5 RC1) tells me the dovecot isn't a valid IMAP4 server. This is usually (maybe always) when I first bring up the client up. If I just ask the client to get the mail again, it does so happily (without any errors). I must say I found dovecot as a pleasant surprise. We have been using UW. Which didn't scale well. I was considering going to cyrus, but dovecot seems to have given much (if not all) of performance improvements without all the hassle of conventing all the existing mbox mail to maildir.

Hi I'm using Dovecot 1.0.stable branch on a production Fedora Core 3 server. All is running very well other than I getting tons of these messages in the log (/var/log/messages): Nov 26 13:38:56 bmw unix_chkpwd[19360]: password check failed for user (xxxx) Nov 26 13:38:56 bmw imap(pam_unix)[19359]: authentication failure; logname= uid=0 euid=0 tty= ruser= rhost=x.x.x.x user=xxxx However the sessions are authenticating correctly and the user is able to down load the mail fine. I have tested this. I send mail to an account then login and download the mail correctly, however my session gets the above in the messages log. Each log on to dovecot get ones of these messages in the log. It making the log file large. Any idea on what it is? Regards Daniel -- "Unix is simple.

[Dovecot] Problem with mysql authentication

Hi, I'm trying to set up dovecot-stable (http://www.dovecot.org/nightly/stable/dovecot-stable-20051124.tar.gz) All seems to be prepared correctly, but... my dovecot can not access the mysql database :( Connection string goes like this (i tried changing the order of parameters, that's why password is the first in the line): connect = password=***** host=/var/lib/mysql/system/mysql.sock dbname=vmail user=vmail But - in dovecot log I see: dovecot: Nov 24 23:53:05 Error: auth(default): mysql: Connect failed to vmail: Access denied for user 'vmail'@'localhost' (using password: TAK) Same in mysql log: 051124 23:53:05 171 Connect Access denied for user 'vmail'@'localhost' (using password: TAK) All settings in connection string are 100% correct - I have pasted them from dovecot-sql.conf to command-line mysql client and it worked, I have logged in. My copy of dovecot has been compiled recently, so all libraries are correct. Mysql version is 5.0.15 - but I doubt it is the reason... Can anyone help? Thanks in advance!

[Dovecot] Newbie question: shared folders means..?
by Jeff Turner 22 Nov '05

22 Nov '05

Hi, The website says "Shared mailboxes aren't yet supported". Does that mean that one shouldn't have two mail clients (same username) accessing the same IMAP account simultaneously? Or that Dovecot doesn't support distinct users accessing the same 'shared' Maildir box? Cheers, Jeff

[Dovecot] Silly question...
by Michael Segel 22 Nov '05

22 Nov '05

I'm trying to build a new 1.0+ copy of dovecot. I'm trying to build it so I can use SSL. I tried the ./configure --with_ssl= option, did a make clean, then a make and a make install. Still get the same error saying that even though I set the SSL use flag, it was not compiled with SSL. Thoughts? TIA! -- Michael Segel Principal MSCC 312 952- 8175 [M]

[Dovecot] Assertion Failure

Here's an assertion failure that just happened. Unfortunately, I don't have a core file so this may be useless... This is with CVS version from 2005-11-03. It looks like he expunges all of his mail. dovecot: Nov 21 17:37:20 Error: 13261 imap(username): mbox sync: Expunged message reappeared in mailbox /mailhome/new/b/n/username/mbox (UID 1008 < 1606, seq=816, idx_msgs=1238) dovecot: Nov 21 17:37:23 Error: 13261 imap(username): file mail-index-transaction.c: line 129 (mail_index_buffer_convert_to_uids): assertion failed: (*seq != 0) dovecot: Nov 21 17:37:24 Error: child 13261 (imap) killed with signal 6

[Dovecot] What's the best way to do this?
by Michael Segel 22 Nov '05

22 Nov '05

Hi, Got a situation where I have a couple of mailing list subscriptions as well as system generated e-mails from my clients' computers sending me warning messages. (Along with my normal load of personal e-mail). Does it make sense to set up virtual mailboxes (maildirs) one for each mailing list or group? Then using an IMAP client to subscribed only to the lists that I *want* to read? My biggest problem is that I have a blackberry and I don't want to get interrupted for non-critical e-mail. Or is there a better solution? TIA! -Mikey -- Michael Segel Principal MSCC 312 952- 8175 [M]

[Dovecot] How to add the footer to multipart emails
by Magnus Holmgren 21 Nov '05

21 Nov '05

I recently lerned that Mailman adds its footer to MIME multipart messages by putting the original message in the first part of a new multipart/mixed entity and the footer in the second part, with Content-Disposition: inline. It works well in Thunderbird at least, i.e. the footer is visible; the glitch is that the footer shows up as an attachment as well, as does my PGP/MIME signature. Would this be something for EoC to adopt? It would allow non-ASCII characters as well (but not in text/plain messages). -- Magnus Holmgren Linköping, Sweden

Re: [Dovecot] messages_count too large (2578 > 2566) Help!
by Rob Frohne 21 Nov '05

21 Nov '05

Hi Everyone, I found that I could "fix" the problem by moving all my messages from Maildir/cur/ to a temporary location and then try and load the inbox using Thunderbird which then saw no messages, and then moving them all back into Maildir/cur/ and then Thunderbird loaded them fine. I have had this funny business with messages_count to large happen twice tonight now. Both times after I deleted dovecot* in the Maildir/ folder. Hope this helps someone else if they end up with the same issue, or perhaps it might help Timo figure out what is happening. Thanks, Rob -- Rob Frohne, Ph.D., P.E. E.F.

[Dovecot] Big THANKYOU to Dovecot development team
by Will Blake 21 Nov '05

21 Nov '05

Time for a positive message. As a (very) part time administrator of a small network running on an ecclectic bunch of machines I'd like to thank the dovecot team for developing such an easy to use and faultlessly functional product. Having been forced into finally replacing my UW IMAP server, I'm glad to have hit on Dovecot after struggling with mailbox transfer issues with cyrus and almost tearing my hair out. On my Fedora4 server, Dovecot was running withing a minute and reading all my folders in five further minutes, thanks Guys, Will.

[Dovecot] Shared Mailboxes, Per User SEEN flag and Mailing lists
by Reikan - Sidney Ferreira 20 Nov '05

20 Nov '05

Hi! Im making a small research about IMAP servers and it's features. As the subject suggests, I want make a shared mailbox, with per user \seen flag to work like a mailin-list works. The reason to use 1 shared folder is simple: Imagine 12k users sending 1KB messages each week, it will be 12+ MB of useless information. Many people told me that IMAP could do this, but now seem that it is a little harder then what they made it look like. Finally, some EXIM users told me that Dovecot could handle it a little better than Courier, so, Im here to try to find more information about it. Follows the mail that I received from an EXIM user.

[Dovecot] Sorting messages by date
by Stephen Allen 19 Nov '05

19 Nov '05

I've recovered a load of messages from a different mail server without it's index file (it was corrupted). I now have thousands of messages which display in Outlook Express (yes, you may puke at this), all as today's date. However when I read them in Pine, the date of each message is displayed correctly, but they're in no particular order whatsoever. There are several questions here, some of which aren't suitable for this list, but for completeness... 1. Does Dovecot store what it thinks is the date the message arrived, in it's index file? 2. Can I fake Dovecot into thinking the messages arrived on a different date by including something in the message headers, or changing the date/time stamp of each file (but I don't know how to do this)? 3. Pine correctly picks out a date from the message (although it doesn't sort by this order), and Outlook Express just displays everything as the date which it (or Dovecot) first saw the message. Does Outlook rely on Dovecot's sorting/date information or does it do it's own? Many thanks, Steve :)

[Dovecot] Can Dovecot work with an RDBMS for mail/attachment storage?
by Michael Segel 18 Nov '05

18 Nov '05

This may seem off the wall, but can dovecot be configured to support a connection to a database server and use the database server to store the e-mail message and its attachments? While you can use Postgres and MySQL for storing and authenticating users, there is a possibility to use an RDBMs to control the mail itself. Thoughts? -- Michael Segel Principal MSCC

Hi, i have a problem with dovecot and quotas, when a user has over-quota he can't access the mail account to download mails and solve the quota problem. I'm using debian sarge (stable) and quota v1 (vfsold), i have installed dovecot in debian way apt-get install dovecot dovecot-common dovecot-pop3d users only can access via pop3 to their mails. This is the error i get when i try to access with an over-quota user pop3-login: Nov 18 12:35:05 Info: Login: prueba [164.73.128.2] pop3(prueba): Nov 18 12:35:05 Error: file_set_size() failed with mbox file /var/mail/prueba: Disk quota exceeded pop3(prueba): Nov 18 12:35:05 Error: mbox file /var/mail/prueba was modified while we had it read-locked, make sure all your software accessing mboxes uses the same locking methods (fcntl, flock, dotlock) pop3(prueba): Nov 18 12:35:05 Error: file_set_size() failed with mbox file /var/mail/prueba: Disk quota exceeded pop3(prueba): Nov 18 12:35:05 Error: Couldn't open INBOX: Internal error occured.

[Dovecot] Retention Policy Feature(?)
by Ted Strzalkowski 18 Nov '05

18 Nov '05

I am currently using dovecot 0.99.14p1 on OpenBSD 3.8, mbox format, procmail+sendmail MTA. I subscribe to quite a few mailing lists and currently have procmail sorting mail into the proper mboxes. I was hoping there would be some sort of retention policy feature built in to dovecot. I want to delete mail more than X days old from X folders. I have combed the documentation, list archives, and google. Is this a feature? If so, where can I find more information on it. If this isn't a feature, is it in the works or is it left out to keep things "slim line"? Ted Strzalkowski

[Dovecot] Authentication hanging with 1.0alpha4 - mysql issue?
by brock＠theskeptik.com 18 Nov '05

18 Nov '05

Hello, Recently, I configured my server (RHEL4, 2.6.9-22.0.1.ELsmp) to run postfix 2.1.5 and dovecot 1.0 alpha4. It connects to a MySQL database (mysql 4.1.12) to verify authentication. From 30 minutes to an hour after dovecot is started, authentication and mail access works perfectly. However, after those 30 minutes to an hour, further attempts to authenticate with dovecot result in "hangs" - no temporary authentication errors are reported to the client, and no errors are logged to the dovecot log. The dovecot is still running, and responds to connections, but once the password is sent, the server fails to respond. The following line is registered in the log with each authentication attempt after the "hang": > dovecot: Nov 17 22:44:41 Info: auth-worker(default): mysql: Connected to localhost (postfix) along with an eventual disconnection notice (although no Login: line is registered): > dovecot: Nov 17 22:45:41 Info: imap-login: Disconnected: Inactivity: method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Killing and restarting dovecot immediately fixes the problem, although it reappears after 30 minutes to an hour. Following is my dovecot-sql.conf: driver = mysql connect = host=localhost dbname=postfix user=dovecot_read password=**obfuscated** default_pass_scheme = PLAIN-MD5 password_query = SELECT password FROM mailbox WHERE username = '%u' user_query = SELECT 89 AS uid, 89 AS gid FROM mailbox WHERE username = '%u' (dovecot_read has SELECT access on the postfix database, and 89 is the uid/gid of the owner of the maildirs.) I searched through this list's archives over the last two months and couldn't find anything related to this. Does anyone have any idea what the problem could be? Regards and many thanks in advance.

[Dovecot] Asserion Failure in Current CVS
by Peter Svensson 17 Nov '05

17 Nov '05

[I am sorry about the broken threading, I do not have the original email to reply to] We are also seeing the following assertion with the current code from cvs: file mbox-sync-rewrite.c: line 106 (mbox_sync_headers_add_space): assertion failed: (start_pos < data_size) After rewriting the file by copying all email to another mbox file from an imap client the error went away. The original file contains sensitive information, but if anyone has sometihng in the file they want us to check we still have the original file. Peter

[Dovecot] Mailbox isn't a valid mbox file
by Cliff Hayes 16 Nov '05

16 Nov '05

Hello all, I have a new installation of Fedora 4 and Dovecot 1.4.Alpha4 A small percentage of my users are getting unable to pop mail from a client (ie: Outlook), they get continually prompted for username/password. The error they get is: Mailbox isn't a valid mbox file. When I look in the file, I don't see anything unusual. There's not much info on the Internet about this problem. The only thing I found mentioned blank lines in the file. So, I tested and found that I'm able to get mail on other accounts regardless of whether there are blank lines in between messages. Thanks, Cliff

[Dovecot] Improper listening on IMAPS
by Marian Hercek 16 Nov '05

16 Nov '05

I want Dovecot handling IMAPS. /etc/dovecot.conf: protocols = imaps imaps_listen = * ssl_disable = no ssl_cert_file = /etc/ssl/certs/dovecot.pem ssl_key_file = /etc/ssl/private/dovecot.pem The problem is that Dovecot is not listening on 993 port, or there's something listening on 993, but it does not introduce itself. There's no problem if Dovecot listens on 143 (IMAP). When I telnet on 143, Dovecot introduces itself like this: $ telnet localhost 143 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK dovecot ready. But when I telnet on 993: $ telnet localhost 993 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. There is not other process that would be listening on IMAPS 993 port. Dovecot was compiled with SSL support: # ldd /usr/sbin/dovecot libssl.so.0.9.7 => /usr/lib/libssl.so.0.9.7 (0x20597000) libcrypto.so.0.9.7 => /usr/lib/libcrypto.so.0.9.7 (0x205c6000) libdl.so.2 => /lib/libdl.so.2 (0x206ba000) libc.so.6 => /lib/libc.so.6 (0x206be000) /lib/ld-linux.so.2 (0x20580000)

[Dovecot] Sub-Folder Query
by Kaan Kivilcim 16 Nov '05

16 Nov '05

Hi all, I have a question in regards to folders/sub-folders with dovecot and Microsoft Outlook 2000. When creating folders if you do not append a "/" to the end of the folder name you cannot create sub-folders. Is there any solution/work around so that users do not have to append a slash on the end of the folder name? I would like to use dovecot for about a 50-user IMAP server however adding a slash to the end of folder names won't go down well with the users who are not the most computer literate people.

[Dovecot] Need to move mail
by Brent Clark 15 Nov '05

15 Nov '05

Hi all My imap server is getting to the stange where I need to start worring about the disk usage. Due to the number of users we seem to be hiring, I need to start looking at a new mail server, suppose its a blessing in disguise too. Would it be ok to just tar my current users mail (there home directory, I dont use virtual setup) and the untar it on the new mail server. Is there anything that dovecot on the new machine will complain about. Obviously I would tar everything, indexes etc. Just something I was wondering. Kind Regards Brent Clark

[Dovecot] a proposal to increase the stability
by Udo Rader 15 Nov '05

15 Nov '05

Hi, we've been using dovecot for the past 2 years or so for our 3K+ mail accounts and have never regretted our step. Yet from time to time there appear to be, how shall I say, "major" problems in the daemon that of course are no reason to whine and complain about because dovecot is OSS and everybody can do something about it. And that's where I would like to make a suggestion. From our own software projects I am used to the usage of extensive testing frameworks, like junit for java based applications. I almost completely lack knowledge about C/C++ programming, so I have no idea if something like this could be done for dovecot. For "the other end" of the mail chain I know dumbster, which is a fake SMTP server used for testing MUAs. So maybe something similar could be done for IMAP/POP3 servers? What I am thinking of is to run those tests before anything new is released. On the other hand I cannot even estimate how much work would be needed for this ...

[Dovecot] Leftover mbox behavior from uw transition
by Adam Porter 15 Nov '05

15 Nov '05

Currently running dovecot 0.99.12 on a RHEL 3 server. This system used to use UW imap with mbox mailboxes, is now using dovecot with Maildir. (Actual user shell logins are not permitted.) Performance is tremendously improved. However, we still have users that have their client imap root set to the "mail" or "mail/" directory. (Can't reach/change them all easily.) As a result, people are still (inadvertently) creating/using mbox-style mailboxes (sent mail folders most often) on the dovecot server (dovecot of course handles them without complaining) which grow and hurt server performance. Now that we've figured this out, I think we could use mb2md in a script to convert these big mbox files to Maildir. (Is there a better way?) But what would be the smart way to prevent people from creating these mbox files and still have their client work correctly with their imap root set to "mail"? We currently use: default_mail_env = maildir:~/Maildir Thanks! -Adam

[Dovecot] entourage pop to dovecot imap migration
by wagner 15 Nov '05

15 Nov '05

I'm beginning to migrate my years of mail stuck in Entourage 2004 (MacOSX) to dovecot imap on Fedora FC4. No matter how I have tried I cannot get the status flags to migrate. Eg: all the mail, once transfered from the pop archive to the imap server looses all Status: and X-Status: flags and ends up being marked "new" on the imap side. After lots of testing it appears that, while simply having both pop and imap configured Entourage and dragging messages from the pop config to the imap area does move messages, all flags are lost. This also is the case if I export Entourage folders as mbox files and then import them into the imap server with Entourage or Mail.app. Has anyone else came upon this obstacle? Any advice? I am in the process now of gathering information to facilitate my own "migration utility". It seems the Entourage DB keeps the read/flagged/replied flags for each message in its own internals and doesn't deem it worthwhile to export them as part of it's mbox export nor retain them as Status or X-Status flags when moving messages from its pop DB to the imap server. I believe I can write a script to work on a set of found, for example, "replied to" messages to add an "X-Status: A" to their headers before moving them to the imap server. Same for "read" and "flagged" MS DB internals to Status/X-Status headers. With these headers added, moving them to the imap server, from my limited testing would seem to be the method to keep those status flags per message? Does dovecot use those flags or does it have its own means of storing that status information? Will it at least use those in the messages to populate its DB if it does have its own method? Flags I've identified so far: Status: O - old Status: RO - recent old(?) X-Status: A - replied to X-Status: F - flagged Thanks for any insight or suggestions.

[Dovecot] problem with content-length and mbox parsing
by Glenn Leavell 15 Nov '05

15 Nov '05

The stars aligned recently such that I sent someone a message that contained a line similar to this in the message body: From glenn(a)usg.edu Thu Jun 20 16:48:11 2002 (Except that there wasn't that space character *before* the From; I've added it here to avoid any problems with this message). Dovecot wrote a copy of the message in my "sent mail" folder under the direction of my imap client. But when I went back to *read* that folder (still through Dovecot), it was broken and was presented as two corrupted mail messages. About a year ago, there was a thread on the list about the fact that Dovecot does not perform >From quoting when writing to mbox folders: http://dovecot.org/list/dovecot/2004-October/004865.html Timo, in that thread you mentioned the following about Dovecot's use of the content-length header: On Tue, Oct 05, 2004 at 05:13:36PM +0300, Timo Sirainen wrote: > Dovecot (and eg. mutt) uses Content-Length header to figure out how > large the message body is, so clients can't mess anything by sending > From-lines. Also Dovecot requires that From-line has correct syntax and > valid timestamp or it's not treated as From-line. In the example above, the message *does* include a valid content-length header after it is initially written, but Dovecot seems to ignore the header when reading the folder, and it treats the "From " line in the body as a message separator. For example, a SELECT on the folder will return "2 EXISTS" even if the single message described above is the only message in the folder. I'm currently at CVS 20051104. Glenn

[Dovecot] IMAP limitation
by Tom Allison 15 Nov '05

15 Nov '05

I was trying to delete a LOT of email messages in one shot from Thunderbird. I selected everything in a folder (>10,000) and then hit DELETE. I received an IMAP error. It clearly implied a limitation to just how many UIDS I can submit on an IMAP request at a time. Is this a limitation of dovecot? (I'm assuming it is). I can work around this, I think, because I haven't found a limitation to retrieving a list of email message UIDS as yet. I could thereby send splices or chunks of that list of UIDS to delete. I ran into this while trying to do a variety of obscene things in my attempts to develop a web mail application. Because of the number of strange tests I have, I don't really "blame" anything since I'm not sure that anyone really expects to delete 10,000 messages at one command.

[Dovecot] TLS negotiation from client fails after openssl upgrade

Is anyone using dovecot on Fedora fc5-devel? I had to rebuild my rpm of alpha4 due to dependencies when I pulled in openssl-0.9.8a (with a whole bunch of other updates). Now when I start my mail client (balsa) it tells me it "Cannot connect to the server: TLS negotiation failed". Dovecot wrote in maillog: "imap-login: Disconnected: rip=1.2.3.4, lip=1.2.3.4, TLS". Does anyone else see that? Can anyone advise me how to debug this? Thanks, Willem Riede.

[Dovecot] Dovecot, Outlook Express and new accounts
by news.gmane.org 12 Nov '05

12 Nov '05

I have come across a strange situation, involving new accounts. I am running Dovecot 0.99.10-5 on Fedora Core 2. Dovecot is configured to use pam for authentication, and the dovecot pam service is configured to use pam_mkhomedir. When an account is created and the user logs in through SquirrelMail, there is no problem. The standard folders are available - Inbox, Drafts, Sent Items and Trash. When logging in through Outlook Express first, it gives the following error:- The server did not respond to this IMAP command before the connection was terminated. Configuration: Account: mail.server Server: mail.server User name: username Protocol: IMAP Port: 143 Secure(SSL): 0 Code: 800ccc0f A packet trace shows the following:- <<< * OK dovecot ready. >>> 008E CAPABILITY <<< * CAPABILITY IMAP4rev1 SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN LISTEXT LIST-SUBSCRIBED STARTTLS AUTH=PLAIN <<< 008E OK Capability completed. >>> 008F LOGIN "username" "password" <<< 008F OK Logged in. >>> 008G IDLE <<< + idling >>> DONE <<< 008G OK Idle completed. 008H LIST "" "*" Connection to host lost. My suspicion that Outlook Express is not intelligent enough to create the folders, although the sudden connection drop might indicate a bug. If it is not a bug, is there a workaround?

[Dovecot] Asserion Failure in Current CVS
by Todd Burroughs 12 Nov '05

12 Nov '05

Just installed the version from CVS as of Oct. 27. I noticed three problems quite quickly: Still seeing "(imap) killed with signal 14" My INBOX closed with "access error" after reading it for a bit. There's nothing in the logs or anything, but this hasn't happened for quite a while now. There where quite a lot of incoming messages at the time and I was marking messages as deleted using pine. After reverting to the last version of dovecot that I was using and restarting pine, it opened quickly (no reindexing) and the deleted emails where marked as deleted.

[Dovecot] dovecot-example.conf error with POP3 UIDL format?

I just installed dovecot 1.0alpha4 on a very busy RHEL4 server with about 1300 users. So far so good, except for the dreaded duplicate emails in outlook for users who use POP3 and have "leave message on server" selected. After searching the archives I found that this is usually related to the UIDL format. The example in the .conf file is this: / # If you want UIDL compatibility with other POP3 servers, use: # UW's ipop3d : %08Xv%08Xu / Note that 'v' comes first, then 'u'.. But, right under it, is this: / # Note that Outlook 2003 seems to have problems with %v.%u format which was # 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. / In this example (and the next example just under it) 'u' comes first, then 'v'. So is the first example right, in that %08Xv%08Xu is compatible with UW ipop3d, but not outlook? Or is the UW ipop3d example a mistake? For what it's worth %08Xu%08Xv seems to have fixed my users' duplication problems. Shayne

I'm running dovecot 20051026 version on Redhat4. I tried to do a stress test. However dovecot dies after I login a few hundred users. I have some error messages in my mail log and am not sure if they are related to the problem.

So its one of the library or the compilation itself that cause the problem of access denied. Any idea??? Thanks

[Dovecot] Moving from mbox to maildir?
by Patrick 09 Nov '05

09 Nov '05

Hi all, New to the list. I have an updated FC4 box with Dovecot version 0.99.14.4.fc4. My mbox size is about 76 megs and growing rapidly because of several high-volume mailing lists I'm subscribed to. I have noticed that over time the performance of the Evoluion/Spamassassin/Dovecot combo deteriorates. Someone on the Fedora users list suggested I have a look at moving to a maildir setup. Reading the docs I can't really figure out what to. Does anyone have a suggestion how I can safely move my mbox setup to a maildir setup? Much appreciated! Regards, Patrick

[Dovecot] mysql dovecot 1.0alpha4
by Pierre Laplante 09 Nov '05

I try to authenticate using mysql and I always get access denied. I wrote a program in C that connect to the database and it work. I put the code within driver-mysql.c and it failed!!! My question is do you set up anything (SSL?) that could explain this failure. thanks. Here is the code MYSQL *h; h = mysql_init (NULL); if (h == NULL) { fprintf (stderr, "mysql_init() failed (probably out of memory)\n"); exit(1); } if (mysql_real_connect ( h, /* pointer to connection handler */ "localhost", /* host to connect to */ "lyra", /* user name */ "xxxxxxx", /* password */ "lyra", /* database to use */ 0, /* port (use default) */ NULL, /* socket (use default) */ 0) /* flags (none) */ == NULL) { fprintf (stderr, "mysql_real_connect() failed:\nError %u (%s)\n", mysql_errno (h), mysql_error (h)); exit (1); }

[Dovecot] Problem with different case logins
by Roberto Suarez Soto 09 Nov '05

09 Nov '05

Hi, we have a system (Debian sarge) that uses LDAP for user authentication, via pam. We also have virtual users by using a static userdb [1], using the directory structure /var/lib/dovecot/postoffice/%u (i.e., a directory under /var/lib/dovecot/postoffice with the name of the user). The directory /var/lib/dovecot/postoffice belongs to postoffice:mail. IMAP folders, indexes and stuff go here; normal mail goes into /var/mail/%u. We are using dovecot 1.0alpha3 (upgrading to alpha4 soon). Today we've found a grave problem. Let's suppose you have the login "mylogin.domain.com". If you instead use the login "MYLOGIN.domain.com", the authentication works anyway (which is Ok), but dovecot creates a new directory under /var/lib/dovecot/postoffice with the different case, i.e., /var/lib/dovecot/postoffice/MYLOGIN.domain.com (which is not Ok). Afterwards, you can only access this new folder if you use the login with the caps. A new file (we're using mbox) under /var/mail/ with the new name is also created, though I don't understand yet how. We're using Postfix as MTA, and it always delivers to the lower case name. I hope you can understand the problem. If an user logs with a name with just one letter changed from lower case to upper case, all his/her folders and mail will be seemingly gone. Is this a bug or a feature? If the latter, is it possible to change this behaviour, or at least work around it? Thanks in advance. -- Roberto Suarez Soto Allenta Consulting robe(a)allenta.com www.allenta.com
