[Dovecot] Looking for a Plug-In developer
by John O'Brien 28 Jul '10

28 Jul '10

Hi, We need a small plug-in developed for dovecot. We are looking to pay for for its development. We need to add support for a custom IMAP command. The command is for the storage of a numeric PIN field in a database. The database is PostgreSQL. Another table in the database defines the minimum and maximum length of the numeric PIN field. The IMAP client server exchange after a user login resembles the following. C: A0001 CHANGE PIN 243289 S: A0001 OK CHANGE successful The numeric PIN number is stored in a field within a table the login username as key. Example errors are: C: A0001 CHANGE PINFJ 24DDD89 S: A0001 NO invalid password type C: A0001 CHANGE PIN 24DDD89 S: A0001 NO invalid characters C: A0001 CHANGE PIN 23 S: A0001 NO password too short C: A0001 CHANGE PIN 234567890123 S: A0001 NO password too long C: A0001 CHANGE PIN 0000 S: A0001 NO password blacklisted We believe this is not a big task for someone familiar with the design and implementation of dovecot plug-ins. We want to minimise our leaning and just get a result. If you are interested in undertaking this development please contact me with a simple proposal. We will require the source code and copyright assignment.

[Dovecot] AntiSpam Plugin
by Leander S. 28 Jul '10

28 Jul '10

Hi, Has anyone got the chance to get this running? I'm permanently getting this Serverbug error ... ;( *"[SERVERBUG] failed to send email"* ... This happens when I try to drag&drop mails from one to the other folder within a IMAP-session. What version of Dovecot must I have to get this plugin working? Or will it generally be broken in upcoming new releases of Dovecot? Best Regards Leander S.

[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!
