[BlueOnyx:04307] BQ-Problem with new Vsite

[Klein Joachim]

Hy to the list!
I have an old mailserver with Nuonce BQ4.8 and 
Mailscanner/Spamassassin/ClamAv.
For the last time it worked without any problem.
But today I want to add a new Vsite and the following error is showed in 
the footer:
Sorry, an error occurred while trying to create an email server map 
file. If mail server configuration files were removed or manually 
modified, please restore the original versions and try again.

I have searched for .lock-files, rebootet after a kernel panic, looked 
some files, but nothing worked.
The DB´s are converted to flat-files with the description from Brian / 
Nuonce.
Only one thing I have found
the file /etc/passwd is copied to /etc/passwd- but I don´t have any idea 
why and I don´t know if this is the problem.

Thanks
Joachim
