Hook behaviour change

[Ben Cooksley]

Hi all,

The KDE Git repository hooks have been adjusted to send emails in a
SPF compliant manner. This means that the address "null at kde.org" will
be used in the MAIL FROM component of the SMTP transaction. The From:
field of emails sent to kde-commits has not been changed by this.

Please let sysadmin know if this causes any problems.

Regards,
Ben Cooksley
