Blowfish hashed passwords
by KT Walrus 03 Jun '16

03 Jun '16

The PHP app I’m using on my website uses PHP to generate password hashes to be stored into the user database. These password hashes use Blowfish encryption ("$2y$”). In fact, since PHP 5.3.0, PHP contains its own implementation of the hash types it supports including: - CRYPT_STD_DES - CRYPT_EXT_DES - CRYPT_MD5 - CRYPT_BLOWFISH - CRYPT_SHA256 - CRYPT_SHA512 The C code for these hash types is in https://github.com/php/php-src/tree/master/ext/standard <https://github.com/php/php-src/tree/master/ext/standard> I’m working on adding Dovecot to my site, but Dovecot doesn’t seem to support Blowfish password hashes (at least on Ubuntu 14.04). Would you consider adding built-in “fallback” support for Blowfish and SHA512 (which doesn’t seem to be supported either on Ubuntu 14.04 last time I checked) to an upcoming Dovecot release? You could probably take the source code from the GitHub PHP repo to incorporate support for these hash types in Dovecot. That way, Dovecot could easily use the same hash types that PHP supports regardless of what hash types are installed in the OS running Dovecot. And, I wouldn’t have to deal with a second set of hashes for Dovecot passdb for my existing user accounts. See PHP manual for crypt function: http://php.net/manual/en/function.crypt.php Kevin

special-use for virtual folder
by Wolfgang Rosenauer 02 Jun '16

02 Jun '16

Hi, I'm running two different Dovecot servers (actually more but those are pretty similar and same versions 2.2.24). Today I configured a virtual All folder on both: namespace { location = virtual:/etc/dovecot/virtual:INDEX=~/virtual prefix = virtual. separator = . } mailbox virtual.All { special_use = \All } On this system the special-use flag is not applied to the folder (checked via LIST "" "*"). On the other system: namespace { location = virtual:/etc/dovecot/virtual:INDEX=~/virtual prefix = virtual/ separator = / } mailbox virtual/All { special_use = \All } On the second system I can see * LIST (\HasNoChildren \All) "/" virtual/All Besides the separator I don't see a big difference between both configurations. Any idea? Thanks, Wolfgang

forwarding emails using sieve
by Thorsten von Eicken 01 Jun '16

01 Jun '16

I know this is a tad tangential to dovecot, but maybe someone has some pointers for me. I'm trying to forward emails using the sieve filtering and redirect doesn't do it because it doesn't wrap the message in a new email, instead, it seems to just change the envelope From (and To). This causes the outbound relay to reject the message for security/spam reasons (forged From). It looks like the dovecot sieve implementation doesn't let me change the From header in the sieve script. Is there a way to accomplish what I'm looking for? Thanks!

Full subject on dovecot log
by Fabio S. Schmidt 01 Jun '16

01 Jun '16

Hi, I've noticed that when a subject is very long Dovecot doesn't show its full lenght on the logs. Is there any way to always register the full subject on the log? (I'm using dovecot 2.2) My best regards, Fabio S. Schmidt

Not receiving mails
by Vijay Kumar 01 Jun '16

01 Jun '16

Hi, I have setup spam filter and opendkim key on our mail server with Postfix,Dovecot and OpenDKIM server. Following are few lines from dovecot.conf which were added to dovecot.conf. After troubleshooting, we removed the following lines and the login from webUI roundcube started working. Can someone please explain the importance of following lines in accordance with Opendkim? Should we disable plaintext authentication for opendkim to work? ----------------------------------------------------- disable_plaintext_auth = no mail_privileged_group = mail mail_location = mbox:~/mail:INBOX=/var/mail/%u userdb { driver = passwd } passdb { args = %s driver = pam } protocol imap { mail_plugins = " autocreate" } plugin { autocreate = Trash autocreate2 = Sent autosubscribe = Trash autosubscribe2 = Sent } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } ssl=required ----------------------------------------------------- Thanks, Vijay --- http://www.matchfinder.in

IMAP Timeouts
by Vince42 30 May '16

30 May '16

Hi, from time to time the IMAP login times out ... my external monitoring says "connection reset by peer (SSL)" and Thunderbird tries to connect forever. After a short while everything returns back to normal operation. The system resources are plenty, there are no error messages and no greedy background tasks running. I read a little about tweaking imap-login - but all the default parameters seem to be set more generously than what was recommended. Where should I start the debugging process? I really wish there was some "dovecot optimizer tool" ... :P -- Cheers, \\|// Vince (o o) ----------------------------ooO-(_)-Ooo------------------------- ''' (o)_(o) [ ][0][ ] ô¿ô (=°o°=) World Domination by Copy and Paste [ ][ ][0] - (")_(") [0][0][0] () ascii ribbon campaign - against html e-mail /\ www.asciiribbon.org - against proprietary attachments Ooo. ---------------------------.ooO----( )------------------------- ( ) (_/ \_)
