Hello everybody, What is the best way to delete an user mailbox (ex: /var/mail/johndoe ) when all attachments (for all users) are in a common directory with SIS deduplication (ex: mail_attachment_dir = /var/mail/attachments ) ? Trying to delete user mailbox directory (rm) and do the command : doveadm -v purge -u johndoe leave all johndoe's attachments orphelin. Best regards, TN

[PATCH] Fix for client certificate validation does not work
by Daniel Dickinson 12 Feb '15

12 Feb '15

Hi all, As I reported earlier (with a typo in the work [BUG]) client certification validation *does not* work even if you do everything exactly according to all documentation and attempts at helpful advice. I have seen this issue with both startssl.com and self-signed certificates, and based on what I've seen from searching the web, this is a problem that has gotten little attention because most people don't bother, but are more than willing to give out useless advice on how to make it work. Furthermore the issue does NOT occur with the cyrus-imap mail server, so it is definitely a server-side issue. The actual issue is that the code for calling OpenSSL that constructs the client certificate validation is in fact WRONG. I don't have a perfect patch as I was mostly interested in getting it working for my needs and didn't bother with constructing the list of CA names to send to the client, preferring to let OpenSSL handle all that sort of thing. What it comes down to is that the code, which probably worked at one point, was not correctly updated at some point and since then client side certificate validation has been BROKEN. I have patched against 2.2.9, however I have seen this problem in the versions in both Debian Wheezy and Debian Jessie as well. As you will see from the patch (which is an attachment as people tend to complain that patches get mangled when you inline them, and even if I have a good client I've gotten heck because the receiver didn't. Regards, Daniel

Processing Maildir contents on message-by-message basis
by Jeff Kletsky 12 Feb '15

12 Feb '15

I (finally) moved over to Maildir storage here and would like to implement some "scripts" to manage taking actions on emails manually identified as misclassified as spam/ham. After reading through the Dovecot 2 description of how it works to try to see how it interacts with other processes changing the files. I'm concerned that I would be corrupting the message indexes if I just go hog-wild and run the scripts on the filesystem, rather than through Dovecot in some way. The types of actions taken would likely be: * Select a message from a given mailbox (the "source") * Potentially modify it drastically (remove spamassassin markup, for example) * Pipe the modified message to a mail-delivery agent (still running procmail here) and/or to sa-learn * Assuming successful completion of the pipe action(s), remove the source message from the mailbox While I can use doveadm to do bulk move/delete actions, I don't see a clear way to iterate through a set of messages and perform actions on them. First off, if I wrangle and mangle the message files directly, do I have to worry about the indexes, or do the indexes "magically" repair themselves in cases where the messages are either altered (including headers) or removed? Have I missed a way to iterate over messages and process it using external tools using the dovecot tools? Has this been discussed ad nauseum and I somehow missed it? (If so, for which I apologize profusely). Thanks, Jeff

Re:Invalid password in passdb: Not a valid MD5-CRYPT or PLAIN-MD5 password

When using CRYPT to encrypt the password, you must put the following in dovecot-sql.conf.ext default_pass_scheme = CRYPT I hope this can help more people, in addition to leave you as I did my query: password_query = \ SELECT password \ FROM users WHERE login = '%u -- editor de sueños

Per-protocol ssl_protocols settings
by Gionatan Danti 11 Feb '15

11 Feb '15

Hi all, I have a question regarding the "ssl_protocols" parameter. I understand that editing the 10-ssl.conf file I can set the ssl_protocols variable as required. At the same time, I can edit a single protocol file (eg: 20-pop3.conf) to set the ssl_protocols for a specific protocol/listener. I wander if (and how) I can create a different listener for another POP3 instance, for example listening on port 10995, and using another ssl_protocol setting. In short, I would like to create a different, firewalled pop3s service enabling the SSLv3 stack, while disabling it at system-wide settings. I am able to successfully create a new listener for port 10995, but I don't understand how to associate the ssl_protocols value to the new listener. Simply putting the ssl_protocols value into the listener section give me a configuration error. Thank you all. -- Danti Gionatan Supporto Tecnico Assyoma S.r.l. - www.assyoma.it email: g.danti(a)assyoma.it - info(a)assyoma.it GPG public key ID: FF5F32A8

Hi friends, I am migrating imap-courier to dovecot, I use openbsd+postfix+imap-courier, and now I'm trying to run openbsd+opensmtpd+dovecot. In the beginning it was a little traumante but it works OpenSMTPD correctly. Now I have configured dovecot, and I hope that your backend authorization is the same database that was used imap-courier. In /var/log/maillog receipt the following error auth-worker(2915): Error: sql(user(a)domain.tld,199.254.238.134): Invalid password in passdb: Not a valid MD5-CRYPT or PLAIN-MD5 password My /etc/dovecot/dovecot-sql.conf.ext password_query = \ SELECT login, password \ FROM users WHERE login = '%u' My database MySQL to start as well mysql> CREATE DATABASE mail; Query OK, 1 row affected (0.01 sec) mysql> use mail Database changed mysql> CREATE TABLE domains ( -> id INT NOT NULL PRIMARY KEY AUTO_INCREMENT, -> domain VARCHAR(255) NOT NULL UNIQUE); Query OK, 0 rows affected (0.02 sec) mysql> CREATE TABLE users ( -> id INT NOT NULL PRIMARY KEY AUTO_INCREMENT, -> login VARCHAR(255) NOT NULL UNIQUE, -> name VARCHAR(255) NOT NULL, -> password CHAR(13) NOT NULL, -> uid SMALLINT NOT NULL DEFAULT 2000, -> gid SMALLINT NOT NULL DEFAULT 2000, -> home VARCHAR(255) NOT NULL DEFAULT '/var/vmail', -> maildir VARCHAR(255) NOT NULL, -> quota VARCHAR(10) NOT NULL DEFAULT '10000000S'); Query OK, 0 rows affected (0.01 sec) mysql> CREATE TABLE alias_maps ( -> id INT NOT NULL PRIMARY KEY AUTO_INCREMENT, -> account VARCHAR(255) NOT NULL UNIQUE, -> alias VARCHAR(255) NOT NULL); Query OK, 0 rows affected (0.00 sec) mysql> GRANT SELECT ON mail.* to 'vmail'@'localhost' IDENTIFIED BY 'vmail'; Query OK, 0 rows affected (0.01 sec) mysql> FLUSH PRIVILEGES; Not for me this past this error to insert data in the database, I do this: mysql> INSERT INTO users (login, name, password, maildir) -> VALUES ('name(a)domain.tld', 'name lastname', ENCRYPT('pass'), -> 'domain.tld/name/'); Which helps me is well received Thanks for all -- editor de sueños
