When I started working for myself, I also took the opportunity to live outside the US for a while. As I was renting out my house and didn't want to trouble my friends and family with dealing with all my mail, I started researching mail services. This site was born out of that research and my subsequent experiences using mail services. I'm living in Costa Rica now and am happy enough with my virtual mailbox that I'll keep using it when I get back to the US.
I like having my mailing address separate from my physical address so I don't have to notify a bunch of people when I move. And most of all I like having a pdf record of my mail that I can access from anywhere. Hopefully one of these mail services will work as well for you as it has for me.
