Hello, If I try to use the crypt schemes provided by libc. I fail as follows: jnikula at jlaptop:~/$ doveadm pw -s SHA512-CRYPT -p 123456 {SHA512-CRYPT}$6$to2umWLDtqvzS8SV$ZGpBeGNKuUN/2HKG6I2BEAt.Gzrz/y.SZDkos2GT2ik8obnp3XCFWfVsKVriJa6jjHULmLIqCSSyaF5YrTH7u. jnikula at jlaptop:~/$ doveadm pw -t

Hi, Not sure if this is a PBKAC or not:- root at ds3:/usr/share/postfixadmin# doveadm pw -s SHA512-CRYPT -p password {SHA512-CRYPT}$6$aUgGXP0UshkMj7hY$9JV4yMRsjIe/98CzmglYrMjf.9NJ.FXzxcLE9B0v3doCRUWo2wRncc6hg6VCs0DCUHQbeC/bRDZdGCge/nB/h/ root at ds3:/usr/share/postfixadmin# doveadm pw -t

When I login through imap, I can see everything in ~/mail/ just fine. I cannot save to any of them. If I have an autocreate-autosubscribe folder (ZZZ here), it shows up as empty (correct). Then if I save something to it through imap, a file ~/mail/ZZZ appears, but nothing actually gets saved to it.

Hello, I've got dovecot authenticating to a MySQL database. I've got a field varchar(128) called password. Whenever I create a password I use doveadm pw as in: doveadm pw -s sha512-crypt now i'd like to get MySQL to make a dovecot-specific password. My goal is to eventually have roundcube's password plugin working with this MySQL database to change the password. Thanks. Dave.

There are no reasonable contexts where is it is acceptable to send mail credentials without encryption. My users have had to use STARTTLS

Running postfix+dovecot+mysql on a mac-mini, and trying to solve this puzzle. Is this a Mac issue?, a MySQL issue? or something I haven't configured in? You can see from the output of the samples shows in the first case, that SHA512-CRYPT seems to be Unknown. The code I used is from a Linux based tutorial on setting up Postfix+Dovecot+MySQL on a site. Everything is generally going ok, apart

Hi, I use Debian jessie with Dovecot 2.2.13-11. While writing a script for Horde to change the passwords in my passwd file I noticed doveadm pw -t fails for SHA512-CRYPT: # doveadm pw -s SHA1 -p test {SHA1}qUqP5cyxm6YcTAhz05Hph5gvu9M= # doveadm pw -t {SHA1}qUqP5cyxm6YcTAhz05Hph5gvu9M= -p test {SHA1}qUqP5cyxm6YcTAhz05Hph5gvu9M= (verified) # doveadm pw -s SHA512-CRYPT -p test

Hi, according to changelog 2.2.rc3, dsync should replicate sieve scripts. Do I need turn on or switch some option(s), for this to work?

After upgrading my dovecot installation about a month ago, I have started seeing "Requested CRAM-MD5 scheme, but we have only MD5-CRYPT" message from dovecot in my logs. Any help in finding and correcting the cause will be greatly appreciated. --Richard

Hi all, Got a question on configuring dovecot, I'm still new at this so I might be doing this all wrong. I want dovecot to authenticate the mail client using CRAM-MD5 so I've setup the config in dovecot.conf: auth default { mechanisms = cram-md5 passdb sql { # Path for SQL configuration file, see doc/dovecot-sql-example.conf args = /etc/dovecot/dovecot-sql.conf

Howdy, I'm using dovecot and mysql users, and i'm creating the password with: ENCRYPT('some-passwd',CONCAT('$6$', SUBSTRING(SHA(RAND()), -16))) So far so good, everything's fine. Today saw that i didn't enabled CRAM-MD5, but if I do, and the (at least) IMAP client (roundcube/thunderbird/etc) issues CRAM-MD5 it doesn't authenticate. What am i doing wrong, or

Hi there, I'm currently running my auth against CRAM-MD5 only. But I face problems with customers who apparently have smart phones which ONLY support plain-text authentification ;( Bad - I know, but what should I do ... ;/ So my question now is: Is it possible to run CRAM-MD5 as well as Plain-Text auth together with Postfix if Postfix is using Dovecot's SASL auth service? Cause

Hi, I'm just in the middle of setting up dovecot to serve IMAPS -- Actually I've finished apart from one thing: CRAM-MD5 passwords. I'm using SQL as a backend for the password storage, and I don't want to store the passwords in plaintext. I've also configured dovecot to be rather restrictive when it comes to authentication methods (only CRAM-MD5 is allowed). To generate the

hello dovecot community, question; if my user database and dovecot installation is currently setup to use plain login passwords, and i want to convert to cram-md5, after i configure dovecot accordingly and reset passwords into cram-md5, if anyone uses plain login method again in the future, will it still work? or must they always from this point on use encrypted passwords? Thanks. -- Thanks,

Hello, I'm running dovecot 1.0-0_12.beta8. Since I have only a very small number of user on that server, I have their names and password in text files, no databases. imap works both via webmail and via Kmail Is it possible to have, for the same user, a plain unencrypted password when connecting via imap on the local interface (needed, as I understand it, to be squirrelmail compatible) and a
