[Dovecot] securing dovecot proxy connections
by bill-dovecot＠carpenter.ORG 06 Sep '07

06 Sep '07

The wiki <http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy> page says this: "The connections created to the destination server can't be TLS/SSL encrypted.". Hrmm. Right now, with perdition, I'm forcing the use of STARTTLS on the internal connections. I'd just as soon get rid of perdition (to have one less moving part in my architecture), but I need the secure connections. Is there a way to configure dovecot's internal proxy connections to use STARTTLS or some other SSL/TLS level of security? (Without a bunch more research, I don't know what the interaction is between the real client, the dovecot proxy, and the destination server.) -- bill-dovecot(a)carpenter.ORG (WJCarpenter) PGP 0x91865119 38 95 1B 69 C9 C6 3D 25 73 46 32 04 69 D6 ED F3

[Dovecot] How do I use sieve to move bounces?
by Jef Driesen 06 Sep '07

06 Sep '07

How can I use sieve to move bounces and non delivery reports (i.e. anything with an empty envelope from) to a special mailbox? I placed this snippet at the start of my sieve script require ["envelope", "fileinto"]; if envelope :is "from" "" { fileinto "INBOX.Reports"; stop; } But mails are not moved to the reports mailbox, and they are still processed by the rest of the script.

[Dovecot] OT Project idea: IMAP plugin for Google Desktop
by Kenneth Porter 06 Sep '07

06 Sep '07

Posting here, as Dovecot seems to be the premier IMAP server available. In case anyone is looking for something to work on, I found today that Google Desktop only understands email clients that keep mail on the client, and it would be nice if there was a plugin that understood IMAP. Here's a site that seems to explain how to write such plugins: <http://www.plugindevelopment.com/>

Dovecot has been working fine for months. We are using 1.0. Come in to work today and dovecot quit working POP3 and IMAP. I restarted the service and everything started working except IMAP? We use Dovecot as an authentication method for outgoing mail and it works. I can't telnet to myhostname.com 143, Squirrelmail will NOT work either. Where is a good place to start looking for signs of the problem. When we restart we get no errors, which is strange? K

[Dovecot] alert function (possible WIBNI)
by Stewart Dean 05 Sep '07

05 Sep '07

The imapd spec has a provision for an alert pop-up of any ASCII text message contained in /etc/imapd.alert on the IMAP server. Can I assume this is implemented on DC? It'd be real nice if in addition to the current all-users message, it was possible to do a per-user alert...but I guess that would be something for IMAP standards....... -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] Dovecot + Sieve
by Marcin M. Jessa 04 Sep '07

04 Sep '07

Hi guys. I installed dovecot 1.0.3 with sieve plugin. It looks like sieve is loaded fine by dovecot [1]. I set up dovecot to use sieve globally: protocol lda { mail_plugins = cmusieve quota sieve_global_dir = /usr/local/etc/sieve/Junk ..... } And created a sieve file which is supposed to move all the Spam marked by dspam to users's Junk folder (listed as Junk in the subscriptions file) : require ["fileinto"]; # Move spam to Junk folder if header :contains ["X-DSPAM-Result:"] "Spam" { fileinto "Junk"; # Stop here so that we do not reply on spams stop; } I also set up postfix to use pipe mail through dovecot: mailbox_command = /usr/local/libexec/dovecot/deliver The problem is dovecot seems to be ignoring my sieve rule and delivers emails directly to INBOX. Any idea how to fix that?

[Dovecot] comparing pointer to integer?
by "Bérczi Gábor (Gabucino)" 01 Sep '07

01 Sep '07

For example in src/lib/file-cache.c: if (cache->mmap_base == MAP_FAILED) { Should be fixed, probably like this: if ((int)cache->mmap_base == MAP_FAILED) { There are a lot of occurences for these in the source. GCC only warns because of this, but DEC C is known to consider this an error: Error: file-cache.c, line 79: In this statement, "new_base" and "(-1)" may not be compared for equality or inequality. if (new_base == MAP_FAILED) { And indeed, unsigned integers and -1 are rarely equal. -- Gabucino

[Dovecot] rule of thumb for indexing overhead
by bill-dovecot＠carpenter.ORG 30 Aug '07

30 Aug '07

I realize it's hard to be precise about this, but does anyone have a feel or rule of thumb for a couple of aspects of indexing overhead? 1. Proportionally, how much space does it take for all 4 files? If I want to give my users a quota of 100 MB for messages, how much real space should I plan for so that I won't run out of space for indexing? 2. What's the overhead in rebuilding index files? Suppose I use an LDA other than dovecot, so at least the INBOX index is frequently getting out of date. Does it cost much (in CPU, memory, and disk IO) to rebuild the index files? (I'm using maildir.)

[Dovecot] (slightly OT) syncing / migrating IMAP mailboxes
by Gunter Ohrner 28 Aug '07

28 Aug '07

Hi! I fear this may be slightly off-topic but it's both related to IMAP and to dovecot: Is there any good and in paticular realiable program for synching / migrating one IMAP mailbox to another? The most important features for me is that a) no mails are lost / left out silently and b) the porgram is able to sync the complete mailbox including all folders without just giving up in the middle of the transfer. If it's somehow possible, I'd like to migrate directly from one IMAP account to the other, without running the synchronizer on one of the servers and without accessing one of the Maildirs directly. I simply want to migrate my existing IMAP account from one Dovecot server (running 1.0beta5) to a new one (running 1.0rc15, as that's the version in Debian stable). Actually, a large part of the mailbox including most / all folders is already present on both servers, but I recently noticed that a few thousand mails are still missing. The current mailbox state is the result of two earlier (obviously incomplete :-( ) migrations a few months ago, from the original Dovecot 1.0beta5 server to a Cyrus server, and - shortly thereafter - from there on to the currently used Dovecot 1.0rc15. So far I've tried offlineimap, imapsync and mailsync, none of which seems to be really usuable. :-( The current state with the incomplete mailbox was caused by mailsync. When I did the first two migrations, mailsync looked like the only program which worked, but seems to have "forgotten" the missing messages. Another extremely suspicious thing is that mailsync reports "phantom changes" if run again immediately after synching a folder and will start to delete and copy / "sync" dozends of messages even if none of the folders actually changed after synching. I've read the name "imapsync" on this list several times, but I just tried it and just tried version 1.219. It happily starts synching the mailboxes and copying messages, but stops after partially synching the first folder - it simply exists, leaving no informational or error message whatsoever... Restarting imapsync will not help, it will appear to start synching the first folder again, but silently exit without doing anything. Some of you seem to use imapsync as a migration tool for production systems, how do you cope with these situations and how do you ensure a mailboxs' migration actually completed successfully? As you're probably not playing Roulette with your customers' or companie's eMails, I'm interested in your receipts to successfully use imapsync myself. As the third application I tried offlineimap (4.0.x-branch). During the migration a few months ago offlineimap (4.0.16 IIRC, synching from a Maildir to a remote IMAP account) was unusuable as it continuously and reproducibly threw exceptions at me during syncing obviously caused by specific messages in the accounts. Unfortunately, I wasn't able ti get any successful help on the offlineimap mailing list this time. :-( Now, synching from one IMAP account to another, specifiying the new server as the "local" account, offlineimap did not throw exceptions caused by mail messages so far, but it's performance is unusuable. It seems to use the "local" IMAP account on my target sevrer in a way which causes Dovecot to utilize all CPU power, copying one message every 10 to 20 seconds - this way, a sync would take ages and frequently aborts because of connection problems. The target server is an Athlon64 3700+ machine... So, does anyone have any pratical solution on how to migrate one IMAP mailbox to another? For various reasons I'd really prefer to go with a tested and working, reliable solution instead of starting to debug complex non-working programs I do not halfway understand and for which I cannot seem to get reliably support from its authors and/or its user community... :-/ Thanks a lot in advance for any pointers to a solution, Gunter -- +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ "The obvious mathematical breakthrough would be development of an easy way to factor large prime numbers." -- Bill Gates from The Road Ahead, p265 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ + PGP-verschlüsselte Mails bevorzugt! + +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

[Dovecot] Some customers receiving duplicate e-mails
by Patrick - South Valley Internet 28 Aug '07

28 Aug '07

Hi all, I posted this question in the Postfix users mailing list as well - I'm not sure if this is Dovecot or Postfix related. Our old system which we migrated off of was an AIX 5.2 machine running most recent Postfix and mbox format with UW-IMAP. We've migrated to most recent Postfix, using Maildir and Dovecot v1. After we used mb2md to migrate over all our customers, some of our customers have called in to let us know they are receiving duplicate e-mails. It's not happening to everyone, it's random (well, I'm sure it's not really random, I haven't found the issue yet). I don't even know where to start. I looked at the logs, but everything looks fine. How can I troubleshoot something like this? Have any of you experienced the same issue? Thanks in advance.

[Dovecot] MANAGESIEVE patch v7 for dovecot 1.0.3
by Stephan Bosch 27 Aug '07

27 Aug '07

Hello dovecot users, I have updated the MANAGESIEVE patch to fix a recently reported problem. This is a patch against the latest stable release 1.0.3. It currently won't compile with 1.1 due to significant changes in the master code. Change Log V7 ------------- - Robin Breathe indicated that the regex capability was missing in the server's SIEVE listing. It turns out I forgot to make arrangements for setting ENABLE_REGEX in the cmu libsieve sources, so the regex extension was not compiled in. I copied the configure.in section regarding ENABLE_REGEX from dovecot-sieve-1.0.2 and that fixed the problem. This patch still includes (yet another) instance of the CMU Sieve source, as explained in one of my previous e-mails (http://dovecot.org/list/dovecot/2006-July/015016.html) The patch can be downloaded at: http://sinas.rename-it.nl/~sirius/dovecot-1.0.3-MANAGESIEVE-v7.diff.gz The README.managesieve is located in the root of the dovecot source tree after applying the patch. Have fun testing the patch. Don't hesitate to notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl IRC: Freenode, #dovecot, S[r]us

[Dovecot] Restoring a deleted/moved imap folder
by Oliver Schulze L. 27 Aug '07

27 Aug '07

Hi, one user of my imap server just deleted a whole folder, blame thunderbird I have the server disk and running Stellar Info for deleted files recovery. My cuestion is about how dovecot deleted an imap Maildir folder? The imap client is configured to move the deleted mails to the Trash folder, so I think dovecot would delete every Maildir email after successfully moved it. In the case a folder is deleted, is something special dovecot does to the email? Or it just run the unlink() function? In the case of compacting a folder, I think thats just a client side action. Many thanks Oliver -- Oliver Schulze L. | http://tinymailto.com/oliver Asuncion - Paraguay | http://www.solojuegos.mobi

We've run into a situation where the Dovecot master process "dovecot" runs out of file descriptors on Solaris 10 since the default is only 256: # plimit 1 1: /sbin/init resource current maximum time(seconds) unlimited unlimited file(blocks) unlimited unlimited data(kbytes) unlimited unlimited stack(kbytes) 8192 unlimited coredump(blocks) unlimited unlimited nofiles(descriptors) 256 65536 vmemory(kbytes) unlimited unlimited Output from "pfiles" after we raised the limit manually: # pfiles 26378 | head -10 26378: /ifm/sbin/dovecot -c /etc/dovecot.conf Current rlimit: 16384 file descriptors 0: S_IFCHR mode:0666 dev:327,15 ino:18128 uid:0 gid:3 rdev:13,2 O_RDONLY|O_LARGEFILE /export/zones/dovecot/root/dev/null 1: S_IFCHR mode:0666 dev:327,15 ino:18128 uid:0 gid:3 rdev:13,2 O_RDONLY|O_LARGEFILE /export/zones/dovecot/root/dev/null 2: S_IFCHR mode:0666 dev:327,15 ino:18128 uid:0 gid:3 rdev:13,2 O_RDONLY|O_LARGEFILE # pfiles 26378 | tail -10 243: S_IFIFO mode:0000 dev:324,0 ino:2038192 uid:0 gid:0 size:0 O_RDWR|O_NONBLOCK FD_CLOEXEC 246: S_IFIFO mode:0000 dev:324,0 ino:2048002 uid:0 gid:0 size:0 O_RDWR|O_NONBLOCK FD_CLOEXEC 247: S_IFIFO mode:0000 dev:324,0 ino:2048441 uid:0 gid:0 size:0 O_RDWR|O_NONBLOCK FD_CLOEXEC 258: S_IFIFO mode:0000 dev:324,0 ino:2042076 uid:0 gid:0 size:0 O_RDWR|O_NONBLOCK FD_CLOEXEC 459: S_IFIFO mode:0000 dev:324,0 ino:1311426 uid:0 gid:0 size:0 O_RDWR|O_NONBLOCK FD_CLOEXEC Perhaps the Dovecot master process should raise it's own limit to the allowed maximum when it starts? (getrlimit()+setrlimit()), or be user configurable? Has this been discussed somewhere before? - Peter
