[Dovecot] dovecot lda & sieve: resubmit folder for resieving
by Axel Thimm 28 Jul '10

28 Jul '10

Hi, I'm currently restructuring my mail archives and migrated from a decade and a half old procmail supported solution to sieve. While doing so I often found that I'd like to filter a bunch of messages (with "bunch" in the area of 1-10K) with my shiny new sieve script. I found in the wiki a way to do that: http://wiki.dovecot.org/HowTo/RefilterMail And it works well, it picks the mails via IMAP and resubmits them to dovecot-lda. But unfortunately the IMAP flags including \Sent, \Flagged etc are lost in the process. I started checking for other solutions beside getmail that might extract the imap flags as well, but I wouldn't know how to pass them to dovecot-lda. Would it make sense to suggest to have dovecot offer this kind of reprocessing itself? That way nothing would get lost in any transition. -- http://ATrpms.net/

[Dovecot] SSHA256 scheme
by Patrick Westenberg 28 Jul '10

28 Jul '10

Hi again, I`m a bit confused how to store a SSHA256 password in the database and I can`t find any information in the wiki. Do I have to store the SHA256 hash and the salt separately (what would the password_query be like in this way) or just the final SSHA256 hash? Regards Patrick

[Dovecot] Cyrus Virtual Domains: Domain migration from Cyrus
by Denny Schierz 27 Jul '10

27 Jul '10

hi, we want to migrate from Cyrus 2.x to Dovecot 1.x (!). We use the virtual domain feature from Cyrus for a better disk partitioning: /var/imap/domain.a/user/foo .. /var/imap/domain.b/user/foo .. /var/imap/domain.c/user/foo .. In a exported skiplist DB, it shows like: ================= domain.a!user.foobar 0 int foobar(a)domain.a lrswipcda postmaster(a)domain.a domain.a!user.han 0 int han(a)domain.a lrswipcda domain.b!user.solo 0 int solo(a)domain.b lrswipcda domain.b!user.yoda 0 int yoda(a)domain.b lrswipcda domain.c!user.luke 0 int luke(a)domain.c lrswipcda postmaster(a)domain.c That allows us, to separate the domains from each other on the filesystem. The cyrus imapd.conf config: defaultpartition: domaina partition-domaina /var/spool/imap/domaina partition-domainb /var/spool/imap/domainb partition-domainc /var/spool/imap/domainc What is the best way, to use this layout under Dovecot? cu denny ps. Cyrus gets this mails via LMTP over TCP from sendmail and Dovecot 1.x dont' have this service and I use postfix for smtp-> smtp-local-lmtp-> Dovecot. -- Denny Schierz <linuxmail(a)4lin.net>

[Dovecot] using Lazy_Expunge to enforce retention policy
by Jim Salter 26 Jul '10

26 Jul '10

Hi, I've been experimenting with using Lazy_Expunge as a tool to enforce document retention policies (by keeping users from deleting emails forever, instead expiring them after a set time). My problem is, how do I keep the user from deleting/expunging mails *inside the expunge folder itself*? I am using dovecot-1.2.10 built from FreeBSD's ports tree, and I am using the following settings for the "expunged" folder of Lazy_Expunge, as part of the "three namespaces" approach suggested in the wiki: # namespaces for lazy_expunge plugin: namespace private { prefix = .EXPUNGED/ separator = / location = maildir:/usr/local/vpopmail/domains/%d/%n/EXPUNGED } When a user expunges mail, it shows up in the folder listed just fine. But if the user expunges mail from /that/ folder, it's gone forever, which defeats the purpose in regard to "enforcing retention." As a partial workaround, I tried adding hidden=yes and list=no to the setting, and restarting dovecot: # namespaces for lazy_expunge plugin: namespace private { prefix = .EXPUNGED/ separator = / location = maildir:/usr/local/vpopmail/domains/%d/%n/EXPUNGED hidden = yes list = no } The problem is, while this does indeed *hide* the namespace from the user, it doesn't prevent them from *using* it if they know about it - I discovered this because Thunderbird still "remembered" the namespace from before I hid it; experimenting confirmed that, yes, I could still use Thunderbird to go into my expunged folder and permanently delete any email in it. If I remove the account from Thunderbird *completely* and reset it up from scratch, I can no longer "see" the namespace - but that's weak security at best, as I can still manually navigate to it and wreak havoc. How can I use Lazy_Expunge to completely PREVENT users from deleting email permanently? Thank you!

[Dovecot] Dovecot 2 and expire
by Brandon Lamb 26 Jul '10

26 Jul '10

expire_dict = proxy::expire I found this expire_dict somewhere, might have been the 1.x wiki, but on the expire plugin page there is no mention of it. I am trying to troubleshoot why my mysql table has no entries. Do I need this line? Is that correct for using mysql? In dict {} I have expire = mysql:/etc/dovecot/conf.d/dovecot-dict-expire.conf.ext and in plugin {} i have expire_dict = proxy::expire expire = Trash 30d expire2 = Trash/* 30d expire3 = Spam 14d expire4 = Spam/Removed 6h expire5 = Spam/Delivered 2d expire6 = Deleted* 30d expire7 = Archive 30d Contents of dovecot-dict-expire.conf.ext connect = host=servername dbname=mail user=un password=pw map { pattern = shared/expire/$user/$mailbox table = expires value_field = ts_expires fields { username = $user mailbox = $mailbox } } I must admit I dont understand what pattern means, I just copied from something when I was setting this up.

[Dovecot] Dsync error when working dir o-rwx
