I check with my Secretary of State for advisement on the issue. According to the strict wording of the Colorado statute, a physical address is required for the resident agent and post office boxes are not permitted. Their position (for now) is that a private mail box company with a PHYSICAL address is satisfactory.
You may want to call your own secretary of state and check. You can find all the numbers from links on my site: www.legalwiz.com
