I've tried 2 builds of dovecot, based on a amd64 rebuild of the experimental package on http://xi.rename-it.nl/debian/ I've tried to include as much useful info as possible, sorry if I've missed out anything of use.

[Dovecot] Dovecot as a email storage system
by Roderick A. Anderson 24 Feb '09

24 Feb '09

I was thinking about all the old email I have and don't want to get rid of and how much space it is taking on my mail server. The idea came to me to install Dovecot on a server at home then I could drop mail into I want to save. It doesn't need to receive mail except what that is moved to it. Anyone see problems with doing this? Thanks, Rod --

[Dovecot] email stuck in outbox
by barnaby cockcroft 24 Feb '09

24 Feb '09

Can anyone here help me out with a client side Outlook issue? I know outlook is a horrible imap client :( We intermittently have a problem where mail gets "stuck" in Outlook users' outboxes. Might have anything to do with dovecot? Is there anyway I can troubleshoot this server side? Are there any settings I can tweak? We have a new and an old dovecot server (see below) and both exhibit the same behavior (occasionally) for heavy mail users. We haven't ruled out a layer 2 issue but nor have we found one.... If anyone has any ideas (other than suggesting a different email client), they'd be much appreciated. Dovecot version(s) 1.19 & 0.99.11 Configuration from 1.19: # 1.1.9: /usr/local/etc/dovecot.conf # OS: Linux 2.6.9-78.0.13.ELsmp i686 Red Hat Enterprise Linux ES release 4 (Nahant Update 7) ext3 syslog_facility: local0 ssl_cert_file: /usr/local/etc/ssl/**************** ssl_key_file: /usr/local/etc/ssl/***************** disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login mail_location: mbox:/home/%u/mail:INBOX=/var/spool/mail/%u mbox_write_locks: fcntl auth default: debug: yes passdb: driver: pam userdb: driver: passwd

[Dovecot] Broken dovecot-uidlist files
by Ulrich Zehl 24 Feb '09

24 Feb '09

I have just upgraded to 1.1.8, hoping to fix these types of errors: Jan 20 10:39:27 laura deliver(xxxxxx(a)example.net): Broken file /srv/storage/mail/store/net/example/xx/xxxxxx/Maildir/dovecot-uidlist line 156: Invalid data: Jan 20 10:41:19 laura dovecot: POP3(yy.yy(a)example.at): Broken file /srv/storage/mail/store/at/example/yy.yy/Maildir/dovecot-uidlist line 2: Invalid data: Unfortunately, they still pop up. Since I suspect these errors to be responsible for customers complaining about downloading mails twice, I'd like to fix them. Our setup has multiple servers sharing the same NFS-mounted directory for maildirs and indexes; we have set mmap_disable = yes dotlock_use_excl = yes fsync_disable = no mail_nfs_index = yes lock_method = fcntl As far as I can tell, for at least one of these errors, there was no concurrent access to the mailbox in question. What can I do to solve this problem, or to analyze it further? Ulrich

[Dovecot] Postfix LDA vs the Dovecot LDA + other quetions
by Linux Advocate 24 Feb '09

24 Feb '09

Guys , 1. What is the benefit of using Dovecot' LDA as compared to postfix's LDA? Will there be better performance? And along the same vein, 2. What is the benefit of using Dovecot's SASL as compared to Cyrus SASL? Is there better performance? 3. Quota Management ( Creating, enforcing, notifying ) - is it done thru dovecot or postfix or are both needed? Regards, mgomez

[Dovecot] pkgsrc-ing sieve and managesieve
by Edgar Fuß 24 Feb '09

24 Feb '09

I'm trying to integrate both the new sieve implementation and managesieve into pkgsrc. Managesieve seems to need some dovecot libraries that dovecot doesn't install (lib-storage/libstorage.a, lib-auth/libauth.a, lib-imap/libimap.a, lib-index/libindex.a, lib-mail/libmail.a, lib-charset/libcharset.a, lib-dict/libdict.a and lib-charset/libcharset.a). There seems to be no provision in pkgsrc for the build of a package needing the work directory of the build of another package. Would it make sense for dovecot to install those libraries?

[Dovecot] sieve-test again
by Ian P. Christian 23 Feb '09

23 Feb '09

I'm not sure what it is I'm doing wrong here, perhaps my 'test' mail is not in the format expected by sieve-test. The 'test' file is a file taken directly from a dovecot maildir - so is in the normal format of having headers, a new line, then the body. There is nothing exceptional about this email. Notice how the header below is 'innocent', however it appears that the test is ignoring this header. # grep DSPAM-Res test X-DSPAM-Result: Innocent # cat sievetest require ["regex", "fileinto","envelope","reject","vacation","relational","comparator-i;ascii-numeric"]; if header :contains "X-DSPAM-Result" "Innocent" { fileinto "moo"; stop; } # sieve-test -c ./sievetest ./test Performed actions: (none) Implicit keep: * store message in folder: INBOX Info: final result: success I don't think it's this header, but rather *all* headers, as the following check also appears to fail. if header :contains "To" "o" { fileinto "Spam"; stop; } Am I mis-using the tool? Thanks, Ian

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I'm using dovecot lda in a qmail / vpopmail testing environnement. I would like to replace vpopmail lda with dovecot's one , because of quotas , sieve filers, indexing while delivering ... Everything is working great, except the catchall. If I want to bounce, a first line like "# bounce-no-mailbox" in the .qmail file works, without this line, emails to unknown addresses are deferred and stay in the queue, because they are deliverable for qmail, but not for dovecot lda.

http://dovecot.org/releases/1.2/beta/dovecot-1.2.beta1.tar.gz http://dovecot.org/releases/1.2/beta/dovecot-1.2.beta1.tar.gz.sig Largest changes since v1.1 can be found from http://dovecot.org/doc/NEWS-1.2 Changes since alpha5: - Added support for ESORT extension (also SORT .. RETURN (PARTIAL) from CONTEXT=SORT that allows windowing SORT results) - pop3: If client idles for 10 seconds, commit transaction (allowing mbox to become unlocked). - crashfixes to virtual mailboxes - all kinds of bug fixes, error message improvements, etc. - http://dovecot.org/patches/1.2/stats-plugin.c may give some interesting statistics about commands There isn't really much left to do for v1.2.0 except some small fixing to shared mailbox code. And writing documentation for it..

[Dovecot] IMAP ACLs and global ACLs in v1.2
by Timo Sirainen 23 Feb '09

23 Feb '09

I just committed code for IMAP ACL support based on the code from Kolab people. I did quite large changes though. I also changed how global ACLs are handled. Previously local ACLs could override global ACLs, but now that users are able to modify the ACLs I think it should be the other way around. From what I've heard global ACLs are typically added for things like 1) disallowing user from doing something in specific mailboxes such as expunge messages, 2) giving a specific master user access to some mailboxes ONLY, such as voicemail. For 1) case a user really shouldn't be able to grant himself privileges back but still should be able to share the mailbox to others (so the global ACL should have 'a' privilege). For 2) case a user shouldn't be able to remove privileges from the voicemail. So now the user can freely update the local ACLs in whatever way he wants. But in the end if there are any global ACLs, all the local ACLs for those identifiers are ignored. Also local negative identifiers are ignored, so that e.g. global "user=foo lr" can't be disabled by a local "-user=foo lr" ACL. I guess I should update the Wiki ACL page about how exactly the ACLs are applied now that they're well in my memory. :) One thing I'm not really sure about is the "owner" handling. IMAP ACL specifications have no such concept. I think many/most other servers simply add a default ACL for the user name directly. It's a useful concept though, especially with the global ACLs. So currently Dovecot replies: x getacl inbox * ACL "inbox" "owner" lrwstiekxacd x OK Getacl completed. But should it just internally convert "owner" to "username" when replying? But then again if there's a separate rule directly for the "username" it breaks. Do any of the existing ACL-capable IMAP clients want to see the username in the ACL reply or can they handle "owner" just fine? Also what about global ACLs? The current code just lists them twice with local ACLs, which is definitely wrong: x getacl foo * ACL "foo" "xx" w "xx" lr "owner" lrwstiekxacd x OK Getacl completed. Perhaps the global ACLs could have a prefix character? Maybe '#'? Which reminds me, the current dovecot-acl file is mapped to IMAP ACLs like this: dovecot-acl : IMAP ACL - anyone : anyone - authenticated : authenticated - owner : owner - user=name : name - group=name : $name - group-override=name : !$name So all global ACLs would get the # prefix, like #anyone, #name, #!$name. Any thoughts? BTW. Listing shared mailboxes still doesn't work. I guess we'll see tomorrow if I still have energy to get that done.

[Dovecot] TLS / Dovecot / POP3
by John Espiro 22 Feb '09

22 Feb '09

I am using Thunderbird 2.x as my client, Dovecot on the server (POP3 not IMAP). Currently I have in my conf file: protocols = pop3s pop3 ssl_disable = no ssl_cert_file = /usr/share/ssl/certs/dovecot.pem ssl_key_file = /usr/share/ssl/private/dovecot.pem ssl_parameters_file = /var/run/dovecot/ssl-parameters.dat disable_plaintext_auth = yes login = pop3 In Thunderbird, I have the email server setup to: - Port 110 - TLS Here's my question: If I change protocols = pop3s pop3 to protocols = pop3s I can no longer connect to my mail server via Thunderbird unless I setup Thunderbird to use SSL. Am I doing something wrong? Thanks, John

[Dovecot] LDAP documentation cleanups
by Timo Sirainen 22 Feb '09

22 Feb '09

I remember some people also complained how the LDAP documentation was messy. Here's my attempt at cleaning it up: http://wiki.dovecot.org/AuthDatabase/LDAP Anything still unclear? (Other than SSL/TLS setup. Someone who knows how it really works should write something there.)

[Dovecot] Problem with v1.1.10
by Cyrus Rahman 22 Feb '09

22 Feb '09

I've been using 1.1.8 successfully but tried out 1.1.10 this morning. I have a combination of system and virtual users. The system users were unaffected by the change, but the virtual users all lost access to their mail because their home directories, as interpreted by dovecot, moved from user@domain to user@user@domain. The location of the home directory is given to dovecot for virtual users using the static db as uid=vmail gid=vmail home=/var/vmail/%u mail=maildir:~/Inboxdir Were there any changes in this area that might have caused the problem?

[Dovecot] dovecot 1.2 virtual folders question
by Robert Schetterer 22 Feb '09

22 Feb '09

Hi Timo is this possible a possible setup ? for downloading imap folders ( including inbox ) with pop3 controlled by a a dovecot-virtual file in usr/local/virtual/%d/%u/ with content something like that * -Trash -Trash/* -Sent -Sent/* -Drafts -Drafts/* all namespace private { separator = / prefix = "" location=maildir:/usr/local/virtual/%d/%u/:CONTROL=/usr/local/virtual/%d/%u/:INDEX=/usr/local/virtual/%d/%u/ inbox = yes subscriptions = yes list = yes } namespace private { prefix = virtual/ separator = / location = virtual:/usr/local/virtual/%d/%u:LAYOUT=maildir++ inbox = no } it doesnt work yet, but i am nearly sure that i havent understand http://wiki.dovecot.org/Plugins/Virtual perhaps you might bring me on the way background : i want to include a global sieve rule which sorts marked spam mails in a subfolder of inbox called Junk, so that users never can overide it and set perhaps an autoreply by an Sieve rule by incomming mail to inbox to make it possible that pop3 users may fetch sorted Spam mails outta the Junk folder too, i wanna use virtual setup folders Trash , Sent , Drafts are standart folders are standart and should be ignored with that -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

[Dovecot] DIGEST-MD5 user/realm mismatch with Postfix
by Darren Pilgrim 22 Feb '09

22 Feb '09

This is a follow-on to the "SQL field format for digest-md5?" thread. After some additional debugging, I've found the problem is a mismatch in what Dovecot expects and Postfix uses for the user and realm. For a username "user(a)example.com" and password "sekret", Dovecot expects: username = "user" realm = "example.com" but Postfix sends the checksum of: username = "user(a)example.com" realm = "" How do I fix this?

Did you already solve this? If not, just mail the strace output to me privately and I'll take a look at it.

[Dovecot] One Dovecot serving 2 domains - possible?
by k bah 22 Feb '09

22 Feb '09

I'm talking about Dovecot 1.0.x, since 1.1.x showed some problems on some of my servers. -- Is it possible to have Dovecot on one machine serving two different domains? How can I set the mailboxes root to one domain to /dir1/ and to the other domain to /dir2/ ? I want all mailboxes from one domain to reside on a different mailbox root. I use Dovecot LDA. Is is possible to set a LDAP config to one domain and another LDAP config to the other (the auth part, I wan't users to reside on different bases on my LDAP tree, so search bases need to be different) thanks in advance = Scrublade Wipers New, Heavy Duty, wiper design to remove bugs and road slime. http://a8-asy.a8ww.net/a8-ads/adftrclick?redirectid=2b9f0c9f1afcc5e7181028e… -- Powered by Outblaze

[Dovecot] auth-worker always opens PAM session
by Miguel Di Ciurcio Filho 21 Feb '09

21 Feb '09

I'm using Dovecot 1.1.7 on CentOS 5.2. I've changed my passdb from passwd to pam, it works fine, but I've found this messages on /var/log/secure: dovecot-auth: PAM adding faulty module: /lib64/security/pam_limits.so dovecot-auth: PAM unable to dlopen(/lib64/security/pam_limits.so) dovecot-auth: PAM [error: /lib64/security/pam_limits.so: failed to map segment from shared object: Cannot allocate memory] Latter I realized that my auth_process_size was 64. Changed it to 128 and problem solved. But I suspect that dovecot should not be opening sessions, because there is no session=yes on my passdb configuration. According to the docs: args = dovecot [session=yes] [setcred=yes] [failure_show_msg=yes] [cache_key=<key>] [<service name>] session=yes makes Dovecot open and immediately close PAM session. Some PAM plugins need this to work, such as pam_mkhomedir. I checked the source code in passdb-pam.c: struct pam_passdb_module { struct passdb_module module; const char *service_name, *pam_cache_key; unsigned int pam_setcred:1; unsigned int pam_session:1; unsigned int failure_show_msg:1; }; And this: /* -session for backwards compatibility */ if (strcmp(t_args[i], "-session") == 0 || strcmp(t_args[i], "session=yes") == 0) module->pam_session = TRUE; It seams to me that the session is going to be opened anyway, since pam_session is always TRUE.

That is wath I do not understang. Can I have dict quota and mail_plugins=quota at the same time? How do I do? Thanks
