Using one MySQL server for both servers? If the server running MySQL is down, mail service on another server will be down too.

Re: Install using Remote Mysql

You can try to install 2 iRedMail servers, let's say server A and B, and run MySQL on server A.

*) Update iptables rules to allow remote MySQL connection through port 3306.
*) Grant privilege for SQL 'vmail' and 'vmailadmin' to allow remote connection from server B.
*) On server B, update Postfix/Dovecot/Roundcube/Policyd (or Cluebringer)/Amavisd config files to query MySQL server on server A instead of localhost (127.0.0.1).

Salted MD5.

Re: Install using Remote Mysql

sure i see that is salted md5 ( with 8 charterer random ) but what is the random char in that string ? for example that is salted md5 = > $1$HV98gvCH$Hr1/Zy5cTDrD0d9MD/TQY. makes from iredadmin
and  that string must be md5 . salted string or salted string . md5 right ?

other ways
how can i change it to plain MD5 ? just from iredadmin setting ? or i need to change something in postfix and dovecot ?

You can generate random strings as salt.

Postfix uses Dovecot as SMTP SASL authentication server, so what you need to care about is just Dovecot.
To use other password hashes, check this tutorial:

Re: Install using Remote Mysql

hello Dear Zhang

i have resolved that problem , i wrote an php class for making that password

that is not just simple md5 it's unix_md5_crypt
unix_md5_crypt() provides a crypt()-compatible interface to the rather new MD5-based crypt() function found in modern operating systems.
It's based on the implementation found on FreeBSD 2.2.[56]-RELEASE

salt is random 8 character and start after $1$ adn end befor $
 
now there is another problem i have more that 5 days im confused

( i found a bug in iredadmin when you trying to install iredmail with remote mysql with that article http://www.iredmail.org/wiki/index.php? … sql.server
roundcube dose not install correctly and roundcube username password and table dose not makes in remote mysql ) anyway i have resolved that problem


all thing is good i can login with roundcube and send an receive email
i have another email interface like roundcube that script using imap  for send and receive email
when i try to config that script from another server to connect to iredmail server and using imap face me error and a can see that error ,log in dovecot

Mar 09 13:24:48 auth-worker(31424): Info: mysql(192.168.1.10): Connected to database vmail
Mar 09 13:24:50 imap-login: Info: Disconnected (auth failed, 1 attempts in 2 secs): user=<test@mydomain.com>, method=PLAIN, rip=192.168.1.21, lip=192.168.1.11, TLS, session=<z6qPwy/0IwCaL6AL>
Mar 09 13:24:59 imap-login: Info: Disconnected (auth failed, 1 attempts in 6 secs): user=<test@mydomain.com>, method=PLAIN, rip=192.168.1.21, lip=192.168.1.11, TLS, session=<TeHawy/0PACaL6AL>


but roundcube can work correctly ! roundcube installed on that iredmail server but my other script is installed on another server that can access to iredmail server over localnetwork
