Mail Route is another (http://www.mailroute.info/), and of course there is Justin's company. As an added benefit these services will also spool your mail in the event of your mail server being down. We do this often with Postini. Really nice as you don't have to do anything with DNS when migrating from Exchange 2003 to 2007, 2010, or whatever mail service you're implementing. Just spool the mail on Postini, do your mail server work, configure the mail server to accept mail from Postini, make sure Postini is configured to send mail to the new server, and then release the spool. Great way for any business to get the email server resiliency they should have at a low price. -- Andrew S. Zbikowski | http://andy.zibnet.us IT Outhouse Blog Thing | http://www.itouthouse.com
