This is not an evidence, but a strong doubt: the same problem is still present after replacing MailScanner by amavisd-new.

[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 just locks on these corrupt mailboxes :-/ I didn't try Dovecot 1.0, as it is alpha and I don't have any package for that anyway (production system :-/ ).

[Dovecot] Solaris build failed
by GARY GENDEL 14 Sep '05

14 Sep '05

dovecot-v1.0-alpha build failed for Solaris 11 (OpenSolaris Nevada). The problematic line is in socket.c line 228. The fix should be to change SOL_TCP to IPPROTO_TCP found in netinet/in.h. This change should work universally on all platforms. Gary

[Dovecot] what does this mean: Warning: Error in custom flags file / Corrupted Indexes
by rick tait 13 Sep '05

13 Sep '05

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
by Patrick Galbraith 12 Sep '05

12 Sep '05

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] variable expansion in dovecot.conf?

[Dovecot] Do index files need removing when upgrading 1.0-stable to 1.0-alpha1 or later?
by Chris Wakelin 11 Sep '05

11 Sep '05

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] 1.0alpha1: stack frame core

Hi, Today's core dump from 1.0alpha1 came from a syslog message of: IMAP(user): pool_data_stack_realloc(): stack frame changed gdb info on the resulting core dump attached.

[Dovecot] subscriptions or .subscriptions?
by Andy Cravens 11 Sep '05

11 Sep '05

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
