[Omail-admin-devel] Error: Insecure dependency...

[<d65...@es...>]

Hello,
  I installed omail-webmail and when a user have a new mail, it only browse a
blank screen in navegator.

  I have looking at logs and I found an error "Insecure dependency while running
system with -T siwcht...".

The problem is done in the code that copies the new messages to 'cur' directory.
Exactly at instruccion 

system("/bin/cp","$sourcefile","$destfile"); 

over line 2766 aprox.


I'm not a guru of perl, please i need help.

Thanks
