Is it possible to control the value of the SMTP time out setting? Occasionally when I send an email, mail.app attempts to use an SMTP server that is available only via a VPN connection (such as the SMTP behind the corporate firewall at work). When it can't reach such a server, it takes about 5-10 minutes until it finally brings up a dialog to let me switch to a reachable SMTP host. I would like to change that 5-10 minute value to something more reasonable like 30 seconds. Thanks.
