Postfix mysql connection

[mrobot]

Hi guys, i have little problem.
A few months ago i started using Sentora on my VPS for my web´s.
I was using 3rd mail client which is not stored on my server but there is a few limitations for me.


Then i decided to run my own mail client (roudcube) which is installed in sentora.
When i was installing a made same mistake with postfix cofiguration and now:
1. i can create a mailbox
2. i can login to roundcube with mailbox
3. but i cant send or recieve mail :    ( 250 - SMTP Login Error)

I was looking for some fix-solution i found a problem with:
The postfix see my unix users but cant see users in mysql database - (sentora_postfix)
Any idea how to fix this problem?
I cant reinstall sentora, because there is a hundred visittors at real-time, and plenty of running web services.

Probably the best solution is find postfix mysql configuration file, but i spend hours and cant find it ...

Sentora does not use Unix users, therefore the configuration is set to use a custom config that uses a database for users/mailboxes. 

Postfix configs (Ubuntu): /etc/sentora/configs/postfix and /etc/postfix

I know what you mean, and i know it! But let me explain simple situation:
I register a new mailbox in sentora
I open webamail which ich roundcube and login to my created mailbox
Everything is ok but when i want to recieve or send email the error window is saying 250 SMTP login error

This problem happend because roundcube is trying to send email via postfix email server but cant auth in this server..

Postfix dont have user list which created sentora. And then cant auth incomming sendmail request.

There is a lot on Google about this common issue: Google: roundcube postfix 250 SMTP login error

Finaly i found the solution: I´ve deleted %u and %p tags from roundcube config and enabled insecure plaintext auth (in postfix)...

For little moment roundcube send my mail withour errors but when i logged out and tryied to log in the login screen is saying IMAP server login error.
