[Dovecot] Changing the order of plugin execution.
by "Fábio M. Catunda" 25 Mar '08

25 Mar '08

Hi! I'm using an acl to avoid deletion of .Trash messages, but I also have mail_log plugin enabled, but I found out some logs of deletion on info.log: deleted: uid=218, msgid=<200802150943.25163.alessio(a)skye.it>, box=Trash The message is still there, but maillog logged that it have been deleted. I believe that this issue is related to the order that plugins are executes, is there a way to change it? dovecot version 1.0.13-1 debian package. Thanks!

25 Mar '08

Hello, I use a simple sieve file like: require "fileinto"; if header :contains ["From"] ["root"] { redirect "test(a)domain.com"; } When I send an email with root to this user, I have this error in my deliver log: Mar 12 09:43:18 helm deliver(user(a)domain.net): open(~/.temp.hostname.net.53398.23c1b1a363c2c4e8) failed: No such file or directory Mar 12 09:43:18 helm deliver(user(a)domain.net): msgid=<20080312084317.C01BD37FEC13(a)hostname.com>: forwarded to <test(a)domain.com> Why I have this error?

[Dovecot] Pegasus Mail 4.41 OK With Dovecot
by Sabahattin Gucukoglu 25 Mar '08

25 Mar '08

Pegasus Mail 4.41 is an excellent client on Windows. It works fine with both Dovecot IMAP and POP3 (APOP, IMAP LOGIN commands only - no SASL). Responds to async events. Supports IMAP STARTTLS. Does not use IDLE - periodic CHECKs. Fast and sensible header caches, light on resources. Offline mode, but read-only, using cache (prefetch options available if body caching enabled, it's not by default to save disk space). Searching is still a bit slow, although it does its best to use IMAP substring searches when it's possible even though the folder metadata is apparently managed locally. Excellent configurability; includes semantics for the different types of separator, prefixes, and a choice of whether or not to support folders w/ messages or w/o in folders. Moves mails for trash; only purges from the Trash folder (expunge after every delete operation and don't provide end-user experience different than local folder management). Provides several tricks for faster IMAP access, one of which is to assume only the client is using the mailbox (they can all be turned off). Closed source. But a very nice client, all round. http://www.pmail.com/ http://community.pmail.com/ Cheers, Sabahattin -- Sabahattin Gucukoglu <mail<at>sabahattin<dash>gucukoglu<dot>com> Address harvesters, snag this: feedme(a)yamta.org Phone: +44 20 88008915 Mobile: +44 7986 053399 http://sabahattin-gucukoglu.com/

[Dovecot] Dovecot and kmail IMAP resources
by Anne Wilson 25 Mar '08

25 Mar '08

For some time now I have been trying to get IMAP resources working on KMail. I have followed the docs from kde, but they tell how to configure cyrus IMAP, so I've had to learn as I went along. After a lot of help from the postfix list I now have a working sasl. The ability of the user 'groupware' to log in with PLAIN has been checked in a telnet session. Everything in KMail has been set up as in the documentation, but it doesn't work. Now I'm wondering if anything in my dovecot configuration needs changing. dovecot -n # /etc/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/mail/mail info_log_path: /var/log/mail/mail.info protocols: imap listen: *:143 login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login mail_extra_groups: mail mail_location: maildir:~/Maildir/ maildir_copy_with_hardlinks: yes auth default: mechanisms: plain login debug: yes debug_passwords: yes passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/dovecot-auth mode: 432 user: postfix group: postfix master: I'd be thankful for any help. Thanks Anne

Now all works perfectly :-) Probably at http://wiki.dovecot.org/Plugins/xexec it is good to have link on patch/new version of module, created by you. Or attach to page file. I can do it, if it's ok. What you think?

Hi, I would like to know if it's possible to avoid message deletion in a specific folder. I'm using lazy-expunge like a Trash folder and I don't want the user to enter there and try to erase the message again. Any help is appreciated. Thanks.

You'll have to point your client to an SMTP server which is willing to accept the mails and forward them.

[Dovecot] Quotas from Active Directory LDAP
by Mohammad "Shami" Al-Shami 23 Mar '08

23 Mar '08

Hi Guys, I've been trying to get this to work for 3 days now, but no luck. I have Dovecot set with an Active Directory back-end. Everything is working properly but I can't get user specific quotas.I tried with both 1.0.13 and 1.0-rc7. All users have the same quota which is set in dovecot.conf dovecot -n # 1.0.13: /usr/local/etc/dovecot.conf Warning: mail_extra_groups setting was often used insecurely so it is now deprecated, use mail_access_groups or mail_privileged_group instead protocols: imap ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login valid_chroot_dirs: /var/vmail verbose_proctitle: yes mail_extra_groups: mail mail_access_groups: mail default_mail_env: maildir:/var/vmail/%n mail_location: maildir:/var/vmail/%n mail_debug: yes mail_plugins: quota imap_quota imap_client_workarounds: delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep auth default: username_format: %Lu debug: yes debug_passwords: yes passdb: driver: ldap args: /usr/local/etc/dovecot-ldap.conf userdb: driver: ldap args: /usr/local/etc/dovecot-ldap.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 user: dovecot group: dovecot plugin: quota: maildir:storage=10240 dovecot-ldap.conf uris = ldap://172.16.201.138:3268 dn = CN=LDAP User,OU=Special Users,DC=shami,DC=net dnpass = qwerty auth_bind = yes ldap_version = 3 base = dc=shami,dc=net user_attrs = sAMAccountName=home,title=quota user_filter = (&(ObjectClass=person)(sAMAccountName=%u)) pass_filter = (&(ObjectClass=person)(sAMAccountName=%u)) user_global_uid = 1001 user_global_gid = 1001 I'm storing the quota in the title field (tried other fields as well) in the following format: maildir:storage=512000 Yet I still get 10MB for all users.

The attached patch provides a compile fix to make it compile without warnings for dovecot-1.1. I only tested whether the module is successfully loaded by Dovecot and not whether XEXEC still does what it is supposed to. It does not segfault on the xexec command, but that is all I tested. I got a backend command error and now it is bed time for me, but there is a good chance that this works if you bother to read the wiki page properly ;) So, consider this to be more like an 'It compiles! Ship it!' kind of fix. But, anyways, it should help you to get where you want. Just apply inside the xexec directory using the usual patch -p1. Let me know what you find out. Regards, Stephan. Thank you, Stephan, for your help. Patch applies without any problem and compilation was successful.

[Dovecot] Using IMAP keywords instead of mailboxes for spam with dovecot-antispam
by Jan Oravec 20 Mar '08

20 Mar '08

Hi, Some email clients, like Evolution, use IMAP keywords to flag spam instead of moving mail to dedicated spam mailbox. This is very useful, as false positives can be easily "moved" to original mailbox simply by removing $Junk keyword. I couldn't find a way how to integrate antispam software, like dspam, with dovecot, so that antispam automatically learns ham/spam. I have found Johannes's dovecot-antispam plugin. Unfortunatelly, it doesn't have IMAP keywords support, autolearn is based on folders. Is there any solution for this use case? Thanks, Jan

by Stephan Bosch 20 Mar '08

20 Mar '08

Hello Dovecot users, Last week I announced my automatic Debian repository for dovecot-1.1. Asheesh Laroia requested source package support and as promised I built it this weekend. Now that it has succesfully released new packages for Timo's latest changes I have activated the new script. To use the source packages you must add the following line to your /etc/apt/sources.list deb-src http://xi.rename-it.nl/debian/ testing-auto main Package versions now look as follows: 1:<upstream-version>-0~auto+<build number> Current latest version: 1:1.1.rc3-0~auto+3 For questions, comments and requests, you can send me an e-mail. Regards, -- Stephan Bosch stephan(a)rename-it.nl IRC: Freenode, #dovecot, S[r]us

[Dovecot] Dovecot 1.0.13 ignores auth_krb5_keytab settings

Greetings, i am using here FreeBSD 7.0-RELEASE amd64 with dovecot 1.0.13. Gssapi auth on our dovecot setup did not work for some time, so i wanted to fix it today.

[Dovecot] IMAP - multi-simultaneous-user mail store
by Tim Alberts 19 Mar '08

19 Mar '08

I'm finishing converting from POP to IMAP and I'm seeing some potentially powerful uses, but I wonder if my ideas aren't more abuses. I want to create 'multi-user' accounts that allow groups of users to archive and share emails with each other. For example, in the case of a sales department, emails from customers may have requests for new product features. I could create an IMAP storage for sales that allows the sales staff to copy these requests into a common email account. These could then be sorted and searched by the product development team to better determine what customers want where product development should go. Another example, a service/support group has some problem customers that frequently call multiple technicians for support. The service group can save all correspondence with this customer in a single location so they can better work together to provide support for this customer. The possibilities for sharing emails in groups seem endless to me, but it depends on if it's a 'use' or 'abuse' of the IMAP protocol, and if Dovecot in-particular is designed to be able to handle this. Thoughts?

[Dovecot] Converting from UW-IMAP to dovecot - odd client problems
by Michael Durket 19 Mar '08

19 Mar '08

Our installation currently uses an old version of UW-IMAP. Instead of upgrading to the latest version, we're in the process of testing dovecot 1.0.13 on a Solaris 9 machine (using a different set of network ports of course so both the old and new systems can coexist during testing). We've been asking selected users to switch from UW-IMAP to dovecot in order to test various clients and OSes with dovecot. On our system the inboxes are always on local disk, but the indexes and any folders may be on NFS or local disk (it has to do with how and where we added disk as our user population increased over time). Only a single server is ever used and I've made sure for our version of dovecot that the settings specified for NFS are as described in the Wiki article. We've noticed some oddities which we can't figure out: 1) When siwtching a Thunderbird user running on a Fedora system (latest version of Thunderbird) Thunderbird couldn't see his mail folders even when the appropriate checkbox (Server Settings -> Advanced -> Show Only Subscribed Folders) was unchecked. Clearing out the IMAP Server Directory setting seemed to fix this, but the very next day, the folders were gone again and we've been unable since to get Thunderbird to see them. Using the same version of Thunderbird, running on Mac OS X 10.5.2 yields no such problem. Another problem with this same user involved a test wherein we created a new mail folder and then deleted it. The deletion caused an error message to be displayed (inferior folders, etc) but on the Mac OS X version no such error occurred and the folder was deleted. Investigating the protocol traces for Thunderbird showed that in the error case, it attempted to rename the deleted folder as a subfolder of the Trash folder (thus generating the error message) but on the Mac OS X version, it actually deleted the folder (which would seem to make more sense). The settings pertaining to the Trash folder are the same on both clients. 2) When switching an Apple Mail.app user running on Mac OS X 10.4.11 (Tiger) at the latest patch level, things appeared to work fine, and then the user mentioned that no mail was showing up in her inbox. Closing and restarting Mail.app appeared to fix that temporarily. She normally keeps a large number of messages in her inbox (approximately 7000+) and receives a large number of messages each day (several hundred). In this case, the Postfix mail logs showed that mail was being received, and the procmail delivery log for this user showed that procmail was putting the mail in her inbox, yet Mail.app was not indicating the presence of new mail (until it was restarted). Also Mail.app became very very slow at startup and shutdown (taking several minutes as compared to a few seconds normally). We've had no problems so far with another Tiger Mail.app user (but his inbox is considerably smaller) and no problems yet with converting a Eudora user running under Windows, but this is a stumbling block in our efforts to convert to dovecot since we'd hoped to be able to switch users over fairly easily (just by changing the port address mostly). While these woud seem to be client problems at first glance, the common factor of course is dovecot. There are no problems with any of these clients using UW-IMAP. I'm hoping that perhaps there are some readers of this list that might have seen similar problems and know of solutions, or could point me to some ways of debugging these problems (with Thunderbird I can at least debug IMAP protocol exchanges, but since dovecot doesn't log IMAP exchanges for specific IPs and since the socket connections are all via STARTTLS I can't use tcpdump so I'm kind of at a loss for how to track these things down short of patching the dovecot code to put in tracing messages). Any suggestions would be appreciated (and would help us complete our conversion to dovecot). Michael Durket

[Dovecot] Dovecot / FreeBSD / Nfs mailstore / Index=memory
by Xavier Beaudouin 19 Mar '08

19 Mar '08

Hello, I have recently changed imap from Courier-imap to dovecot because of serial problems with courier-imap, I have being forced to do it very quickly... and without extensives tests. I have 3 mails servers (freebsd based) behind a load balancer and a nfs mailstore on a netapp. On my first tests I have setup the index into some nfs shared mount, but it seems that some imap clients are going mad when deleting files (mostly because they do open some new imap connection and the index was not clean) so I have changed index to memory. This has fixed one of my problems. Now I have some strange problems is that NFS activity passed from about... 5mbps to more than 70Mpbs... Is there any reasons about that ? OS: FreeBSD 6.2-p11 / x86 Dovecot : 1.0.13 (freebsd ports) Auth: ldap based Nfs mail spool : filer:/vol/vol0/mail /var/mailusers nfs rw,nfsv3,mntudp,bg,noatime,nolockd 0 0 Thanks, /Xavier

If you want to have postfix authentificate from the same Database as Dovecot, you need it, but otherwise I do not see no relation. Or do you installed some script, that checks mails for Groupware-related ones and act upon them immediately? I cannot help you with Postfix. For shared resources you'll need yet another, shared account or look into the ACL plugin. KOrganizer even supports imap URLs natively, I saw right now.

[Dovecot] Missing folders after converting from Courier imap to dovecot
by M. Bobkiewicz 19 Mar '08

19 Mar '08

Hi, I?ve searched around for my problem but couldn?t find a solution. My setup: Centos 5.1 with postfix 2.5.1 (from source) and dovecot 1.0.10 (from source). I?m coming from an old Trustix 2.2 box with postfix 2.2.x and Courier imap with Maildir format mailboxes. For testing I?ve copied over some of the mailboxes from the old machine. After logging in to the new machine with Thunderbird only the incoming and trash folders appear in the Thunderbird sidebar all the rest are not showing up. When you send an email the sent folder appears with all mails this account has sent from the old machine, same with drafts etc. Access a folder directly and it will appear with all it?s content. This is some kind of nasty if you have to do this for several hundred folders. I?ve tried to fix the problem by changing the namespace private parameter "prefix" to ".". Also tried to rename courierimapuiddb to dovecot-uidlist. Both tricks don?t work. Unfortunately I can?t find the mentioned courier-dovecot-migrate.pl, maybe this would help... Any help and suggestion would be welcome. Best regards, Mike
