DMS Tips and Tricks

The Dispatch Messaging System (DMS) uses commercial off-the-shelf (COTS) software called SquirrelMail, which is accessed through the Web and does not require downloading anything to your computer.

While there are no generic user accounts in SquirrelMail, there are generic mailbox folders for each group or office and more than one person can access the e-mail. Users log on using their personal account, subscribe to their group or office’s e-mail folder and are able to see and respond to e-mails sent to their group or office. Some individuals have accounts to use with an incident management team as a regular e-mail system. These accounts are assigned to the individual’s dispatch office or GACC and they will maintain the documents below.

Users will receive their user account information via an e-mail with instructions for logging on to DMS. Each user is responsible for providing appropriate documentation demonstrating adherence to Forest Service IT Security Policy. This includes security training documentation and Rules of Behavior (ROB) acceptance. The dispatch office must receive and file the following documents from each person with a user account in their office and be prepared to present all documentation in the event of an audit:


A copy of an annual security-training certificate for all non-federal users. Federal users may be required to provide information that they have taken ethics and security training for their agency.

In 1998, the National Wildfire Coordinating Group (NWCG) agreed that agencies administrative mail systems did not support the needs of the emergency dispatch community. Based on this, the NWCG tasked the Resource Ordering and Status System (ROSS) project team with developing and implementing an alternative e-mail system for transmission of mission critical information. In the fall of 1999, the Dispatch Messaging System (DMS) was operational nationwide.

DMS is used by wildland fire dispatch community and is a web-based application. It is not any one agency's administrative mail system. It is used between dispatch offices, caches, and Incident Management Teams for mission critical communications.
