Unchangeable passwort?

[Gabriel Ambuehl]

Hello,
I'd like to setup a demo of sqwebmail and qmailadmin for visitors to
our homepage. I need to know how I can set the postmaster
passwort as beeing unchangeable so that visitors can't block everyone
else out... I think that this has to be possible as there's a demo at
inter7's Homepage...

  


Best regards,
 Gabriel
