support for Blowfish $2y$10$
by Graham S. Jarvis 06 Jul '18

06 Jul '18

Hello, does dovecot support bcrypt $2y$ version? (BLF-CRYPT - Blowfish crypt) doveadm pw -s BLF-CRYPT generates a {BLF-CRYPT}$2a$05$....... password. Does this mean that dovecote will not authenticate against a $2y$10$....... password? Thanks in advance, -Graham-

Re: user/password Authentication via Joomla database

Hi, I think there is no reason to be offlist. Your setup should work, only problem could be the freebsd userid. My setup has only one user for all accounts and no "real" users. I only have a vmail user. Maybe a tutorial for dovecot and mysql only would help you ( I don't have a link here, but google has) hope that helps Harald Am 06.07.2018 um 15:18 schrieb Graham S.

Benchmarks with imaptest
by João Paulo Sacchetto Ribeiro Bastos 06 Jul '18

06 Jul '18

Hey guys, Has anybody ever used imaptest to benchmark *ONLY* reads? I'm trying to run a battery of tests in my new cluster and apparently no combination of parameters works, because fetch instruction doesn't run. Below is the command I'm using and its partial output imaptest/src/imaptest host=$SERVER_IP port=143 user=teste%d(a)example%d.com pass=$TEST_PASS users=10 domains=10 clients=100 - append=0 select=100 fetch=100 Logi Sele Fetc Logo 100% 100% 100% 100% 166 156 0 156 99/100 223 230 0 230 100/100 206 203 0 203 97/100 Can anybody help me understand why fetch doesn't work and how to fix this? Regards, -- João Paulo Bastos DevOps Engineer at Mav Tecnologia Belo Horizonte - Brazil +55 31 99279-7092

user/password Authentication via Joomla database
by Graham S. Jarvis 05 Jul '18

05 Jul '18

Hello, did anyone ever set up Authentication via lookups to a Joomla (mysql) database? What I'd like to do is lookup Joomla users (who are in specific/multiple groups) in the Joomla database and then fallback to /etc/passwd authentication to let system users authenticate. I'm running : # 2.2.35 (b1cb664): /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 11.1-RELEASE-p10 amd64 Thanks in advance, -Graham-
