Base e-mail addresses undergo virtual change Published Oct. 26, 2009 By Roxanne Brennan 21st Force Support Squadron PETERSON AIR FORCE BASE, Colo. -- The 21st Force Support Squadron Common Access Card identification section recently underwent an equipment upgrade which will change the e-mail addresses of virtually all 21st Space Wing e-mail users. The 21st FSS is working with the 21st Communications Squadron to ensure a smooth transition from the old address system to the new. The e-mail address of most 21st Space Wing personnel will automatically update in the Defense Enrollment Eligibility Records to read name@us.af.mil instead of name@peterson.af.mil. Customers who have received new common access cards since this upgrade are asked to delete their old certificates from the Global Address Listing and publish new certificates. For more information, call the 21st FSS customer service at 556-4673, option 21.
