Do not update your system to the current svn release as svn relaeses are only for development and shall not be installed on production systems.
To get the changed alias check, you can manually edit the file /usr/local/ispconfig/interface/lib/classes/tform.inc.php and replace the line:
Code:
if(!preg_match("/^\w+[\w.-]*\w+@\w+[\w.-]*\w+\.[a-z]{2,10}$/i", $field_value)) {
with:
Code:
if(!preg_match("/^\w+[\w.-]*\w{0,}@\w+[\w.-]*\w+\.[a-z]{2,10}$/i", $field_value)) {
The code must be aroud line 703, mybe plus minus a few lines as I dont have the current 3.0.1.6 installed here at the moment.
