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

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

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

Best way to delete an user mailbox with mdbox format and all attachments detach/dedup ?
by Tan 11 Feb '15

11 Feb '15

Hello everybody, On a Dovecot 2.x, what is the best way to delete an user mailbox when : * all attachments for all users detach in a common directory (mail_attachment_dir = var/mail/attachments ). * attachments use SIS deduplication (mail_attachment_fs = sis posix) * mailbox are in mdbox Trying to delete user mailbox directory (rm) and do the command : doveadm -v purge -u johndoe , all attachments of this user are orphelins. In another way, is there a dovecot command to delete or to synchronize attachments ? Best regards, TaN

Ok, problem solved. Obviously the GUIDs only have to be unique for a specific user account in dovecot. Many thanks to Heinlein Support who helped me with this question!

Mails Not Deleting in first POP3 Session
by Smith, Michael H. (GSFC-760.0)[NICS] 09 Feb '15

09 Feb '15

The dovecot -n output is attached to this email. Filename dovecot-n_filtered.conf. Dovecot Version: 2.2.10 OS: CentOS 6.6 MTA: Postfix version 2.6.6 The system is using dsync between two mailbox servers. Problem: When a pop3 session deletes a new message and the pop3 session ends, the message is not deleted. On a subsequent pop3 session, the same messages is deleted again and when the session ends, this time the messages is removed. This results in automated scripts getting duplicate messages. Previous mail server utilized postfix and dbmail. The problem did not exist. All of our replication settings are located in the file /etc/dovecot/conf.d/12-replicator.conf. When I move the above file out of /etc/dovecot/conf.d/ on both mailbox servers and restart dovecot, the pop3 deletion problem goes away and the system behaves as expected i.e. when a messages is deleted, it's removed when the session ends (of course its not replicated to the secondary server). Numerous tests using IMAP and deleted messages behaved as expected.with or without replication Here is some additional information that I hope helps: Below I'm running watch 'pwd; ls -l; echo "../cur"; ls -l ../cur | tail -2' On the primary mailbox server: Every 2.0s: pwd; ls -l; echo "../cur"; ls -l ../cur | t...

The new messages remain in the new directory after the first session (as previously stated) on the secondary mailbox server until the dele. So second session deletes appear to work fine Any assistance would be greatly appreciated. --Mike

Postfix , Dovecot & the Spam fight
by Leander Schäfer 09 Feb '15

09 Feb '15

Hi, I'm currently busy with a substiution of my current mail server. I'm currently using * Clam-SMTP and * SpamAssassin to fight Spam. I wonder if it is worth implementing AmaViS with SpamAssassin backend instead and also using AmaViS to speak to clamd directly. But I more and more wonder wether AmaViS is even worth it?! It currently looks to me as if AmaViS is eating LOTS of ressources and it is very uncomfortable for automated installations if you have to do dynamic batch changes on the AmaViS configs - sed(1) is your friend but this hectic escaping and workarrounds is really not sustainable to maintain. So my question is: Does AmaViS have any advantages compared to the current setup? I don't seem to find lots of qualified discussions for this on the net. The AmaViS related articles I found are freaking old. Would be nice the get your best practice as a change. Thanks a lot Best regards Leander
