problem

Since years the support as address is used as default sender e-mail in new installations.

solution

• This should be changed, so that resources.mail.defaultFrom.email is set to an noreply address in application.ini
• ensure where the defaultFrom is probably used as debug / error mail receiver. This was the case in the past, so all occurrences must be checked
• Provide alter script to change that too in the installation.ini file
