[Dovecot] IMAP creates .userid directory even after pop.
by Jorgen Lundman 21 Mar '08

21 Mar '08

We are currently running dovecot-1.0.10 on Solaris 10 x86. Several users has noticed that they get different emails when using pop vs using IMAP. When I check a user's home directory, I find the following situation: /nfs/mail/1/1/hiro.11/mail/: drwx------ 6 176785 1000 512 Mar 21 07:53 . drwxr-xr-x 3 176785 1000 512 Feb 29 17:01 .. drwx------ 5 176785 1000 512 Feb 19 12:52 .hiro_11_c7 drwx------ 2 176785 1000 8192 Mar 21 07:53 cur -rw------- 1 176785 1000 1445 Mar 21 07:53 dovecot-uidlist -rw------- 1 176785 1000 144 Mar 21 07:53 dovecot.index -rw------- 1 176785 1000 57344 Mar 21 07:53 dovecot.index.cache -rw------- 1 176785 1000 66424 Mar 21 07:53 dovecot.index.log drwx------ 2 176785 1000 7680 Mar 21 10:34 new drwx------ 2 176785 1000 1536 Mar 21 10:34 tmp /nfs/mail/1/1/hiro.11/mail/.hiro_11_c7/: drwx------ 5 176785 1000 512 Feb 19 12:52 . drwx------ 6 176785 1000 512 Mar 21 07:53 .. drwx------ 2 176785 1000 512 Feb 19 12:52 cur -rw------- 1 176785 1000 1037 Feb 19 12:52 dovecot-uidlist -rw------- 1 176785 1000 120 Feb 19 12:52 dovecot.index -rw------- 1 176785 1000 24 Feb 19 12:52 dovecot.index.log -rw------- 1 176785 1000 0 Feb 19 12:52 maildirfolder drwx------ 2 176785 1000 1536 Feb 19 12:52 new drwx------ 2 176785 1000 1536 Feb 19 12:52 tmp I suspect that is less than ideal. What exactly is creating these folders, and how do we stop it? I can clean it up ok (which I'd rather do as one maintenance) but only once I know it wont happen again. Should also mention that we have a mbox convert script running for a couple of months, to convert their old mail. Then it will be removed: convert_mail = mbox:/export/mbox/migrate/%u:INBOX=/export/mbox/migrate/%u/%u:INDEX=Maildir:%h/mail/ Should also mention, one server in the cluster was incorrectly running version dovecot-1.0.2 (boy was that fun to track down).

[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

[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
