use IMAPSIEVE to update database with last_read date
by KT Walrus 30 Nov '16

30 Nov '16

Just noticed the Dovecot support IMAPSIEVE extension… Could I use this extension to update an external database with the date that the user last read the message? My app sends certain “notification” messages to the user’s dovecot mail address. The user reads the messages in their dovecot mailboxes only using IMAP. I want to update my app’s database to record this read time for all “notification” messages sent by the app. Seems to me I could write a short sieve script to send a “notify” … [View More]

Sieve script won't compile. Compiler output isn't helpful.
by Steven Mainor 30 Nov '16

30 Nov '16

Hello! I hope you will forgive my ignorance but I have a problem I have been trying to solve for a week and I'm not sure where else to turn. I'm trying to write a sieve script to sort all of my mail. I was writing this script to replace the one I am currently using but I can't seem to get it to compile. I don't know a lot about sieve or really scripting of any kind and I just can't figure out what I'm doing wrong. The compiler just puts out a bunch of output that doesn't make sense. like … [View More]

We are configuring 'Count quota' with 'Quota Clone Plugin' Everything is working perfectly when we set limit in quota_rule(quota_rule = *:bytes=500M).

shared/public mailbox application
by Michael Fox 30 Nov '16

30 Nov '16

I'm new to Dovecot and I need help configuring a shared or public mailbox - I'm not sure which is appropriate. I've read the wiki and Peer's book and neither appears to cover what I'd like to do. So I could use some specific help on how to configure a solution for the following: I'd like to create two real mailboxes, let's call them AAA and BBB. Let's call the domain "mydomain". Anyone user can send mail to them, just like any other address: aaa@mydomain or bbb@mydomain. I'd like all … [View More]

auth client limit versus service count of mail processes

Hello, We've got a pretty substantial dovecot installation (versions 2.1.7 and 2.2.13 on the backends, but tested with 2.2.24 as well) and this is the relevant config snippet from 10-master.conf: --- default_process_limit = 1024 default_client_limit = 16384 [...] service imap { # Most of the memory goes to mmap()ing files.

Hi mailing list, I'm currently running dovecot 2.2.13 from Debian Jessie, all is running fine. However I am attempting to merge 2 LDAP authentication sources.

Rebuild UIDs for mdbox

That last line (Removed message 2147483647 from cache) is repeated ad infinitum. Now, I happened to spot that that number is 2^31 - 1 so started looking to see if claws-mail was handling UIDs incorrectly. That lead me to http://wiki.dovecot.org/Clients/NegativeUIDs. Firstly, that page states that UIDs should be 32-bit integers. If so, why do there appear to be UIDs greater than 3 billion in the mailbox? Secondly, that page gives instructions on how to fix the problem with mbox and maildir backends. However, my mail is stored in mdboxes. Is there a way to re-generate UIDs for mdbox mailboxes? Thanks in advance! [View Less]

CPU for Dovecot
by Miloslav Hůla 28 Nov '16

28 Nov '16

Hi, we are planning to change hardware for our standalone Dovecot instance handling ~5800 IMAP users with 1TB mailboxes on local RAID. Is there some recommendation about CPU? We can choose from: - Intel Xeon E5-2620v4 - 2,1GHz@8,0GT 20MB cache, 8core, HT, 85W, LGA2011 - Intel Xeon E5-2623v4 - 2,6GHz@8,0GT 10MB cache, 4core, HT, 85W, LGA2011 The difference is about more cores vs. hi frequency. Thank you, Miloslav

Hi to all I have some *production* pop3/inappropriate server that i would like to move under a proxy Some questions: 1. Keeping the same original hostname on the proxy (in example mail.mydomain.tld) and changing the hostname on the imap server, makes some troubles like MUA redownloading all the messages? Is dovecot (running on the imap server) happy seeing the hostname change? What about maildirs, where the hostname is wrote on the mail file? 2. Dovecot proxy will proxy the whole pop3/imap … [View More]

Could the index of dovecot be stored in database?
by eSX 25 Nov '16

25 Nov '16

Hi dovecot, I have a question about the index of dovecot. I had read the wiki, and saw that I can custom a Input streams to do read/seek/sync...by implementing a istream-*.c file. Thus maybe dovecot can read mail from a http server or any others. But I found that the index of maildir can't extend very well. There is no extern API for developer? For example, I want to put the index to database(maybe, MySQL) or any else, But I found I have no way to implement it, Unless a heavy modification? -- eSX

Patch for dovecot-antispam-plugin to support IMAP Flags indicating Junk status
by Jonas Wielicki 25 Nov '16

25 Nov '16

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Dear list, I made a patch which extends dovecot-antispam-plugin with support to take the addition and removal of a specific set of flags as trigger for learning. This allows for very tight integration with Thunderbird and KMail, which both set flags for Junk messages (Thunderbird sets "Junk", KMail sets "JUNK"). With this patch and according configuration, dovecot-antispam-plugin can trigger on the addition (learn as spam) and removal (… [View More]learn as ham) of these flags. Combined with a sieve script which sets these flags for incoming mail which has been classified as spam, this allows for a tight and intuitive feedback loop between users and the server-side spam classification system. I tested that patch with dovecot 2.2 from Debian stretch and so far it works pretty well. I realise that dovecot-antispam-plugin has not been updated since 2013. It also has not been migrated to Github yet. If it is to be migrated there, I would be happy to submit a pull request there for discussion and merging. Otherwise, someone would have to indicate how to go forward with applying this patch to the official version, if that is desired. The patch is based on current tip and feedback is appreciated. I took some inspiration from dovecot-core/src/plugins/notify/notify-storage.c -- this requires the use of struct mail_private to be able to override the vfunc for mail_update_keywords, which I actually do not like. However, when I tried to make this patch base on the use of the notify plugin (via notify_register), I ran into the issue that the transaction is partially freed before the transaction_commit event from notify is emitted, which is unfortunate and breaks at least the mailtrain backend (which I use). This is in theory fixable, but I wanted to keep the patch as small as possible, as I have no idea whether this will eventually end up upstream or whether I’ll have to maintain that for myself. If upstream is not interested in this patch, please let me know! In that case, I would consider making an own plugin, which fewer backends (possibly only a mailtrain-like one) out of this, but frankly, I would consider that a waste of resources. In the hope that this is useful for others and hoping for feedback, Jonas Wielicki -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEEG/EPV+Xzd5wEoQQIwGIDJZdiWIoFAlg4Fd0ACgkQwGIDJZdi WIpM3Q//TWVHDFx5LK14y0jOnxzE7kGthc6hakILnWqYgl7B/wlljD1HLrec//hg 9LEancjURnv3sPU/kEEpl6RRDX5kDMbXXKXMq7/1R7bNdmeMz5NEebAo7ktlCii7 ikk7MPL0F8UViY7IoW7y5NxfqMUldYseejn0GwKiVkEyqlyGLRbP7ijyzMWjpIWp eqOg/b5bNX6ARMC1O/hKhvHw4AhvSO2j73da60Xchu39gvDa2kC+MTU/kX4wb6po kPOEgFxGhpxG0+UMzUEBPLYwY3Q9x+R/PzlpUF6xEjYxgE7leVRVfCHiZLsMUGH1 itozwSzoAyDYV+Rbzk8OEBL6EGBJQHqYmNybULZsJkxhUenNeC4GRf7NcJ0jAisG rSfwr/+kD9+ErKNgtNJzfceLYGNWti44whV6kXxRxqGlIfJsJB7ZMdrj8+wSdn0p slXUoyHMUkRkN92tIPqZF5cb+5Ke+O+5hHE07Wohxw3eNoBSqtQWo81aigjaCraC ivcZX3HswTapyKtpgWMzjoWqp982crr+wtAI+AlEUKoCEqF54EnxM1kB1qoe0HcH nMgMdIkXI4VzPaUNUK206ffEtlnKNIqF3SkOkBX263L0ZJgXyCFRRj6W3z78VDdP He62tN/FPPBtmeVrmCj2ZDE+6gqtMQN52FsN4mpaq4BrCYlYB7g= =3+CU -----END PGP SIGNATURE----- [View Less]

Updated my Dovecot certificate for the first time
by Steve Litt 25 Nov '16

25 Nov '16

Hi all, I've used Dovecot since February 2012, but because I kept reinstalling Linux with every major version, I never had a Dovecot self-signed certificate go bad on me before. Til now. I started using rolling release Void Linux about a year ago, and my Dovecot self-signed certificate just expired. The solution I used is contained in these documents: http://wiki2.dovecot.org/SSL/CertificateCreation http://wiki2.dovecot.org/SSL/CertificateClientImporting file:///etc/ssl/dovecot-openssl.… [View More]

I haven't yet found a way to get Alpine to > discriminate between a valid self-signed cert and a bad one. Well, it can't discriminate since any certificate (except those in your trusted store) that asserts its own validity is suspect. You can either get alpine to not complain e.g. inbox-path={192.168.100.2:143/user=whatever/tls/novalidate-cert} or add the public part of the cert into … [View More]

Active sieve script symbolic link doesn't update when changed.

Good email client to use with Dovecot?
by Steve Litt 22 Nov '16

22 Nov '16

Hi all, When I use an email client, its purpose is as a window into my Dovecot IMAP, and as a mechanism to reply to and send emails. I don't do filtering or calendaring on my email client (filtering via procmail direct to Dovecot). What email clients are all of you using to look at your IMAP email?

LDAP auth problems "unknown user"
by Nikolai Lusan 22 Nov '16

22 Nov '16

Hi, I am setting up a dovecot instance to host a bunch of virtual domains, with ldap backing for auth. I am using a single hostname for test purposes, with a couple of entries in the diectory. If I use auth binds I get a result, but this does not suit the end purpose of the server. If I use ldapsearch with the same base, search filter, and credentials as the ldap auth config I get the correct attributes returned, and I have bit of perl that verifies the password hash matches the password … [View More]provided. I am running out of ideas here, I had thought of putting in a custom bit of perl and using the checkpassword method, but this is sub optimal.
