The Webmail software detects this from the web browser, so it is not set in VPOP3, but it should use the regional settings on the computer running the web browser (assuming the browser passes the details through to Javascript correctly, which all current browsers do as far as we are aware).

In some browsers, eg Google Chrome, the web browser has its own regional settings, rather than using the Windows regions, so you may need to change this in the web browser itself.
