Hi,

I just installed iRedMail on a fresh Debian 7.8 Installation went well, ending with:

********************************************************************
* Congratulations, mail server setup completed successfully. Please
* read below file for more information:
*
*   - /root/iRedMail-0.9.1/iRedMail.tips
*
* And it's sent to your mail account postmaster@solutionboxx.com.
*
* Please reboot your system to enable mail services.
*
********************************************************************

But after reboot nothing really worked. RoundCube had a DB-Error, SoGo did not permit logins, iredadmin had an internal server error.

I checked the MySQL-DB then. The root login I set was working, but no databases or tables were created. Scanning through the log, I found the messages posted above.

Any way I can populate the db correctly at this stage?

thanks, regards
Jochen
