Hello,

Netstat results at the end.

I can connect to the mysql database with myphpadmin and iredadmin, for example. Also when I get to roundcube, I can't log in (sometimes I receive an error like user/password is incorrect and sometimes I do receive nothing (I've also stopped iptables).

What I've seen when I change the ports is that in the file /var/log/dovecot.log I receive these errors:

Jul 28 22:04:32 auth-worker(1231): Error: mysql: Query timed out (no free connections for 60 secs): SELECT password FROM mail
box WHERE username='postmaster@infojobplace.com' AND active='1'
Jul 28 22:04:32 auth-worker(1231): Error: sql(postmaster@infojobplace.com,127.0.0.1): Password query failed: Not connected to
database
Jul 28 22:04:32 auth: Error: auth worker: Aborted request: Lookup timed out

Jul 28 22:04:38 auth-worker(1232): Error: mysql(127.0.0.1): Connect failed to database (vmail): Can't connect to MySQL server

Jul 28 22:05:03 auth-worker(1232): Error: mysql(127.0.0.1): Connect failed to database (vmail): Can't connect to MySQL server
on '127.0.0.1' (111) - waiting for 125 seconds before retry

Then I've modified the file /etc/dovecot/dovecot-mysql.conf and I've modified it adding the port and restarted dovecot:

driver = mysql
default_pass_scheme = CRYPT
connect = host=127.0.0.1 port=2222 dbname=vmail user=vmail password=3L

Now I can login to roundcube but when I try to send a mail I receive the error:

Error SMTP (451): Failed to add recipient user[at]mydomain.com (4.3.0 <user[at]mydomain.com>: Temporary lookup failure

I cannot receive mails neither.

If the port is 3306 (default installation and without modifying dovecot-mysql.conf), all works properly.

The netstat results are:

Thanks in advance again.

I've modified all the ports in all the files inside /etc/postfix/mysql/.
Also I've added the port in the file /etc/dovecot/dovecot-mysql.conf. This file looks like that:

driver = mysql
default_pass_scheme = CRYPT
connect = host=127.0.0.1 port=2222 dbname=vmail user=vmail password=3LI9hFA053wj7d0cGWwDkzZkxU5nEa
# Required by 'doveadm mailbox ...'.
iterate_query = SELECT username AS user FROM mailbox
password_query = SELECT password FROM mailbox WHERE username='%u' AND active='1'
user_query = SELECT \
    '%u' AS master_user, \
    CONCAT(mailbox.storagebasedirectory, '/', mailbox.storagenode, '/', mailbox.maildir) AS home, \
    CONCAT('*:bytes=', mailbox.quota*1048576) AS quota_rule \
FROM mailbox,domain \
WHERE mailbox.username='%u' \
    AND mailbox.domain='%d' \
    AND mailbox.`enable%Ls%Lc`=1 \
    AND mailbox.domain=domain.domain \
    AND domain.backupmx=0 \
    AND domain.active=1 \
    AND mailbox.active=1

Also I've added the port in the file /etc/dovecot/dovecot-used-quota.conf. This file looks like that:

connect = host=127.0.0.1 port=2222 dbname=vmail user=vmailadmin password=NAjMMZ19NF8whnGN3FqlYLz8zfoUyk
map {
    pattern = priv/quota/storage
    table = used_quota
    username_field = username
    value_field = bytes
}
map {
    pattern = priv/quota/messages
    table = used_quota
    username_field = username
    value_field = messages
}

Also I've added the port in the file /etc/dovecot/dovecot-share-folder.conf, as previous files.

But after restart server I can't send/receive mails. In /var/log/maillog I receive:

Jul 30 17:13:05 server postfix/smtpd[1175]: connect from localhost.localdomain[127.0.0.1]

I've also tried to restart iredapd as in the post below, but it doesn't work.

Thanks.

Yes, I can.

[root@server mysql]# mysql -h 127.0.0.1 -P 2222 -u vmail -p

I've activated this log in my.cnf with the command:

log=/tmp/mysql.log

When I send a mail the log shows (I truncate the file before click on send mail in roundcube):

[root@server tmp]# more mysql.log
140731 23:36:33     7 Connect   roundcube@localhost on roundcubemail

                    8 Query     SELECT password FROM mailbox WHERE username='postmaster@domain.com' AND active='1'
                    7 Quit
[root@server tmp]#

In /var/log/maillog appears the same errors as I wrote in previous post.

In /var/log/mysqld.log is empty. I truncate it before send mail also.

It is needed another log file info?

The output is:

postmap: fatal: table mysql:/etc/postfix/mysql/virtual_mailbox_maps.cf: query error: Connection refused

The etc/postfix/mysql/virtual_mailbox_maps.cf configuration file contains:

user        = vmail
password    = xxx
hosts       = 127.0.0.1
port        = 2222
dbname      = vmail
query       = SELECT CONCAT(mailbox.storagenode, '/', mailbox.maildir, '/Maildir/') FROM mailbox,domain WHER
E mailbox.username='%s' AND mailbox.active=1 AND mailbox.enabledeliver=1 AND domain.domain = mailbox.domain
AND domain.active=1

If I change the parameter hosts = 127.0.0.1 for hosts = localhost, the command you've sent works properly. Then I've created a user vmail with access to the host 127.0.0.1 as you can see in the table mysql.user.

CREATE USER 'vmail'@'127.0.0.1' IDENTIFIED BY  '***';
GRANT ALL PRIVILEGES ON * . * TO  'vmail'@'127.0.0.1' IDENTIFIED BY  '***' WITH GRANT OPTION

mysql> SELECT User, Host FROM mysql.user;
+-------------+------------------+
| User        | Host             |
+-------------+------------------+
| root        | 127.0.0.1        |
| vmail       | 127.0.0.1        |
| amavisd     | localhost        |
| cluebringer | localhost        |
| iredadmin   | localhost        |
| root        | localhost        |
| roundcube   | localhost        |
| vmail       | localhost        |
| vmailadmin  | localhost        |
| root        | vps37114.ovh.net |
+-------------+------------------+

But after that when I execute your command, it shows the same error.

And if I try to connect like that, it works properly:
mysql -u vmail -h 127.0.0.1 -P 2222 -p
