Due to unexpected problems with the email service on the server swift16.swiftinter.net we decided to schedule a maintenance for tonight between 10PM and 11PM.
During this period you may expect some outages in the message delivery service.
If you would like to see if your domain name will be affected our service checking script can show you what server your domain name is hosted on. Please visit this link for more information http://swiftinter.net/cgi-bin/service_checker.cgi
Sorry for all inconveniences caused.
