[Dovecot] Dovecot Sendmail Maildir
by Gabriel Granger 11 May '05

11 May '05

Hi all, I'm using Debian (testing) for my office mail. I'm using sendmail and Dovecot to deliver email to clients over IMAP using mbox format. I want to move over and start using Maildir. I know that I can use different MTA's to do the job, but I really like sendmail, and I run additional sendmail servers across the my internal and external networks. I'm probably being anal, but I want to keep my MTA the same across the board. Does anyone here use sendmail + dovecot + maildir? if so what's the best way of going about this? Gabe

[Dovecot] Assertion failed in dovecot 0.99.14
by Quadriplegic Leprechaun 11 May '05

11 May '05

Hi, I am using the dovecot imap server on Linux 2.6.8.1. I get the following error when running it: imap(quad): Panic: file index-sync.c: line 25 (index_storage_sync_size): assertion failed: (messages > ibox->synced_messages_count) This usually occurs when I use imapfilter to move messages from one folder to another, while my client (thunderbird) is connected.

[Dovecot] Outlook 2003 duplicates UIDL
by Alex Needham 10 May '05

10 May '05

Hi I have Redhat ES4.0 with dovecot-0.99.11-2.EL4.1 installed. Reading a post Outlook Duplicates issue is still killing me, there seems to be asolution to this, I was wondering when this will be available on redhat es40? # 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 Rgds Alex

[Dovecot] Standard dirs
by Claudio Succa 10 May '05

10 May '05

Hi, thank to developers for such a flexible imap server. Is solves succesfully my needs to have a single passwd file for clients accessing both imap/imaps and pop3/pop3s protocols (on a diskless mail/web server with NFS maildirs and NFS indexes!). My question: With 1.0-test68 I have to set login_dir=/var/run/dovecot-login (just a dir not under /var/run/dovecot) instead of /var/run/dovecot/login. I guess that imap-login (running with uid=dovecot) can't access /var/run/dovecot/login if it is under /var/run/dovecot because it is set with permission 0700 and uid=root by dovecot. How can I run dovecot with its standard login_dir config?

[Dovecot] start_tls on the user and password ldap connection
by Farkas Levente 10 May '05

10 May '05

hi, it seems when dovecot use ldap user and password databases it's not possible to use tls connection and certificate with the ldap connection. wouldn't it be possible to use the same certificate on the ldap connection as used in the ssl_{cert,key}_file parameters in the dovecot conf (or would be possible to use it's own cert in the ldap conf file? yours. -- Levente "Si vis pacem para bellum!"

[Dovecot] problems with ldap auth
by Nuno Lopes 10 May '05

10 May '05

I'm trying Dovecot v1.0-test43 with ldap authentication but can't seem to make it work. I'm getting the following errors in the log: dovecot: Sep 16 19:50:09 Info: Dovecot v1.0-test43 starting up dovecot: Sep 16 19:50:10 Error: Auth process died too early - shutting down What can I do to see where the error is? I have this configuration working with dovecot 0.99.xx . And if I replace the ldap authentication scheme with another one it starts up right. Following some past mailing list sugestions I've also tried removing most of the auth modules from the compilation but it made no diference. You can see my configuration files in: http://iluvatar.portugalmail.pt/dovecot/dovecot.conf http://iluvatar.portugalmail.pt/dovecot/dovecot-ldap.conf (I've intalled the binaries in /opt/dovecot) Don't know how much more data I can provide to help finding out what the problem is here (I think this won't be enough unless there's a known bug). Thanks, -- Nuno Lopes

[Dovecot] trouble getting digest-md5 & ldap working
by Udo Rader 09 May '05

09 May '05

hi, I am trying to set up dovecot with digest-md5 as authentication mechanism and openldap as passdb. My problem is ... that I just can't get it working. PLAIN authentication works as expected, but no luck with digest-md5. An excerpt from the two configuration files: dovecot.conf: --------CUT-------- auth = default auth_mechanisms = plain digest-md5 auth_userdb = ldap /etc/dovecot/dovecot-ldap.conf auth_passdb = ldap /etc/dovecot/dovecot-ldap.conf --------CUT-------- dovecot-ldap.conf: --------CUT-------- user_filter = (&(objectClass=posixAccount)(|(mail=%u)(uid=%n))) pass_filter = (&(objectClass=posixAccount)(|(mail=%u)(uid=%n))) default_pass_scheme = plain --------CUT-------- My dovecot installation with plain authentication and OpenLDAP has been quite mature for a long time, so I doubt that it is an issue with openldap. >From Cryrus-SASL I know that in order to get DIGEST-MD5 running it is required to have plaintext passwords in the DIT, but that does not solve anything. syslog tells me this: dovecot-auth: May 08 21:25:09 Error: ldap(frodo): No password in reply So any ideas on where I went wrong?

[Dovecot] transparent proxy
by Mark E. Mallett 09 May '05

09 May '05

I'm excited to see that dovecot 1.0-test series supports transparent proxy, but that excitement is muted by: - the recommendation to avoid 1.0 at present; - the requirement to use SQL authentication. I guess I could ignore the first, but the second is sticky. How hard would it be to hack a different sort of proxy server cue into the authentication? Perhaps one of: If authenticating via passwd, use a gid as an index into a server table (or perhaps have the group name be a server name), If passwd authentication fails, try a starting the proxy to a specific other server and see if one can log in there. Or something else.. I dunno, I'm just looking not to install a SQL server just for this. mm

[Dovecot] index file corruption
by Andy Pastuszak 09 May '05

09 May '05

Hello everyone. I am new to the list, so forgive me if this has been discussed already. My configuration is as follows: Fedora Core 3, fully patched through yum through today. Dovecot 0.9.9.13 Postfix 2.1.5 Using Maildir with Mail stored in ~/Maildir My issue is that, for some odd reason the inbox file index gets corrupt, There is no rhyme or reason as to why it happens or when, but a simple rm -rf ~/Maildir/.INBOX fixes everything (I assume because Dovecot rebuilds the index file.) Has anyone else on the list seen this? Is there some workaround for it? Andy

[Dovecot] Problem (?) with 1.0-stable
by Jakob Curdes 08 May '05

08 May '05

... Version from April 26, gives me the following errors in the imap log file : dovecot: May 04 09:56:58 Error: IMAP(m6933192-4): file mbox-sync.c: line 1262 (mbox_sync_do): assertion failed: (sync_ctx->ibox->mbox_sync_dirty) dovecot: May 04 09:56:58 Error: child 10721 (imap) killed with signal 6 This occurs sporadically and vanishes after some time. Is this something to worry about or not. I have mbox_dirty_syncs = yes Or does this just say "I am falling back to reading the whole mailbox"? Yours, Jakob Curdes

[Dovecot] dovecot 0.99.14 and imaps (SSL) "hangs"
by Frode Nordahl 08 May '05

08 May '05

Hello, I just decided to try dovecot again after a long pause, and I must say that I am very impressed with the speed and resource usage, even when running with UNIX mailboxes. However, I have a problem with SSL. Every two minutes the connection is frozen, and the client has to reconnect after it times out waiting for a response from the server. My IMAP client fetches all headers, and then caches all messages in my mailboxes. However, if I do this while connected to dovecot using SSL (imaps, port 993) the connection times out roughly every two minutes, and the IMAP client must close the connection, reconnect and resume operations from where it left off. This makes resynching a 40000 message 300MB folder take VERY long :-) Using the same client, connected to the same server and syncing the same mailbox connecting to regular imap port (no TLS, port 143), everything works smoothly. The very same client, server and mailbox works flawlessly with uw-imapd and SSL. I have turned on rawlog, and everything seems to be OK. I am unable to dump the wire, because it's SSL, so not sure what to do to debug this. One thing I find a bit strange is that /var/run/dovecot/ssl-parameters.dat is a 0 byte file. Is this normal? Client: Apple Mail 1.3.11 (v622) Server: dovecot 0.99.14, installed from ports on FreeBSD 5 dovecot.conf: Regards, Frode Nordahl

[Dovecot] pop vs. imap inconsistancy
by jeff sacksteder 08 May '05

08 May '05

I am converting from courier and have noticed change in behaviour with Dovecot. I use maildirs with squirrelmail connecting by imap as well as a POP3 client. Courier would set the 'mail status-read' flag for any message which was downloaded with the POP3 interface. Dovecot apparently does not. Is this a bug or intended behaviour? If it is intentional, can it be changed with the config file?

[Dovecot] Outlook Duplicates issue is still killing me
by Jeff Ramsey 08 May '05

08 May '05

Hi, I have one pop3 client who has three computers, and he has Outlook XP on two, and 2003 on the third. They are all set to leave a copy of messages on the server, and that causes a duplicate message for every message he gets. I then can tell him to uncheck the "leave a copy on the server" box, and pop his mail, and the duplicates will go away for two or three days, only to start up again. I have a stock Fedora Core 2 server with dovecot and Sendmail. I do a nightly yum, so as to stay up2date. My version of dovecot is 1.0-test42. Has anyone else seen this issue? What can I do to fix it, short of permanently unchecking that box in Outlook? (The user is my boss, and he likes to get his email on all three computers...) -- Jeff Ramsey MIS Administrator Tubafor Mill, Inc.

[Dovecot] Test68 and Namespaces
by Jim Summers 08 May '05

08 May '05

Hello List, I am in the process of building a new mail system here. I am hoping to eventually migrate my users from mbox storage to maildir. They have been using mbox forever and would rather get used to maildir slowly. So I have come upon the idea of using namespaces to provide the different mailstores. Since this isn't available in the current stable, or at least I could not figure out how to do it, I have been working with 1.0-test68 since it provides the ability to configure things with the namespaces. But I am seeing an error pop up in my maillog file when exiting the client, it is: ============================================ May 3 08:11:41 tbox dovecot: IMAP(sub4000): file mbox-sync.c: line 1371 (mbox_sync_do): assertion failed: (sync_ctx->mbox->mbox_sync_dirty) May 3 08:11:41 tbox dovecot: child 12717 (imap) killed with signal 6 ============================================ Wasn't sure if it is a code bug or if it is how I have the namespace entries setup. In my dovecot.conf file I have: ------------------------------------ namespace private { separator = / inbox = yes # prefix = "#mbox/" location = mbox:~/Mail/:INBOX=/var/mail/%u } namespace private { separator = / prefix = md/ location = maildir:~/Maildir } namespace private { separator = / prefix = mail/ hidden = yes } namespace private { separator = / prefix = ~/mail/ hidden = yes } namespace private { separator = / prefix = ~%u/mail/ hidden = yes } ------------------------------------ All seems to work except the message showing up in the logs. My goal/setup is to provide: 1. mbox delivery in the mailspool(/var/mail) from sendmail 2. access to existing ~/Mail/ mbox storage. 3. ability to begin setting up / migrating to maildir in ~/Maildir Is my namespace config above overkill / borken / wrong? Ideas / suggestions on this would be greatly appreciated. Environment: Server to be: RedHat AS EL4 Clients: Thunderbird, Evolution, mutt, pine, mailreader on OS/X.

[Dovecot] test-68 coredump
by Gregory Bond 08 May '05

08 May '05

I've tried upgrading from test-51 to test-68, with mixed results. It seems to fix the problem I had with imap and Thunderbird getting confused and not showing headers or body for some email. But something in dovecot is coredumping when I select certain mailboxes. Thunderbird just hangs when you select that mailbox, and mutt gets an EOF on the imap socket while "fetching message headers". Other mailboxes seem to run OK. The failing ones _might_ be empty or have only 1 message in them. Removing index files doesn't help. There is a core file in /var/run/dovecot, and file(1) says it's from dovecot-auth, but GDB can't make sense of the core with that executable, and the login has well and truly run when the core happens. (The core doesn't seem to be from the imap process either.) Any clues how I might debug this? [Solaris 2.8, gcc-3.3, dovecot test-68, imap+Maildir, Thunderbird 1.0.2 on OSX and mutt on Solaris]

[Dovecot] quota-command?
by Marten Lehmann 08 May '05

08 May '05

Hello, if you log in at hotmail.com, gmx, lycos or yahoo, you can see something like "using 1.4mb of 250mb total". Is there any IMAP command to check to current quota usage? Our webmail-interface will not have access to the filesystem to summarize the size of each file, so an IMAP-command would be great. I don't know if this would be a new feature or just part of the Maildir++ quota-system, that is not yet supported by dovecot. Regards Marten

[Dovecot] Migrating from courier-imap to dovecot
by Odhiambo Washington 08 May '05

08 May '05

Hello Gang, I am new to dovecot and the only reason (so far) I would like to use dovecot, and in production with 12k+ users, is the fact that it's supposed to be faster and less of a resource hog. Now, sometimes I am really good at reading the documentations but it sometimes happens that one overlooks something. I did read the migration notes three times! My users are in /etc/passwd and I am running dovecot in IMAP only mode. I did put default_mail_env = maildir:~/Maildir in dovecot.conf, then for one user, I did the following: cd ~wash/Maildir cp courierimapsubscribed .subscriptions # Then I edited to remove "INBOX." cp courierimapuiddb dovecot-uidlist The permissions are right, but when I login as this user, I don't see all the folders that had been there before when he was using courier-imap!! When I login to the web interface (we use Squirrelmail) and go to the Folder options, I can't see any folders to subscribe to either! Now my questions: 1. What am I overlooking?? 2. Does someone have a script that can be used to automate the copying of courierimapsubscribed to .subscriptions and that of courierimapuiddb to dovecot-uidlist, and the editing to remove the "INBOX."? I am sure I really don't have to reinvent the wheel, no? Meanwhile I am hitting google, while waiting for your answers.

[Dovecot] How to check for keywords in IMAP store?
by Steffen Kaiser 08 May '05

08 May '05

Hello, I'm checking my way to migrate from Courier to Dovecot. Wiki says that "there's currently no easy way to migrate them [the keywords]". Frankly, I lack the information to check if some client is using keywords at all. More importantly, is it OK to assume that when SELECT INBOX returns no \* in OK [PERMANENTFLAGS ...] that the IMAP server does not allow keywords at all? [BTW: Is there a searchable mail archive of the Dovecot list?] Bye, -- Steffen Kaiser

[Dovecot] Setting location for indexes
by dovecot.7.signal11＠spamgourmet.com 08 May '05

08 May '05

We have NFS-mounted user directories which cause significant problems with stale file handles: dovecot: IMAP(uid): fstat() failed with file /home/uid/mail/.imap/INBOX/dovecot.index.log: Stale NFS file handle (a) why can't it just close the file and re-open ? (b) is there a way to specify with the 'default_mail_env' (or in some other way) the location of **only** the indexes (and let dovecot autodetect all else?). I have already tried 'mmap_disable = yes', but that does not solve the problem, and if I set 'default_mail_env = INDEX=/var/spool/mail/INDEX/%u', I get errors like: IMAP(uid): Failed to create storage with data: INDEX=/var/spool/mail/INDEX/uid I don't want to specify mbox:~/mail/ or mbox:~/Mail/, because some users have one and some the other.

I'm using one of the stable 1.0 releases for 184 accounts on Gentoo Linux on Sparc. I too am seeing the message header/body mismatch in Thunderbird.

[Dovecot] pop vs. imap inconsistancy
by jeff sacksteder 08 May '05

08 May '05

I am converting from courier and have noticed change in behaviour with Dovecot. I use maildirs with squirrelmail connecting by imap as well as a POP3 client. Courier would set the 'mail status-read' flag for any message which was downloaded with the POP3 interface. Dovecot apparently does not. Is this a bug or intended behaviour? If it is intentional, can it be changed with the config file?
