When you purchase an e-mail address at wickenburg.us, you can have your mail handled one of two ways:

Forwarding service -- All your mail will immediately be forwarded to the mailbox address that your ISP has assigned you. Your correpondents never need to know or even see that address. They send mail to you at wickenburg.us and you get it; you send mail to them and it appears to come from your wickenburg.us address (through one simple change we explain in our setup instructions).
On your end, you use the same mail client you now use, and access the same mailbox you now access. You still use all the same tools provided by your ISP to change your passwords, control spam, and read your mail from a browser.
If your "home" e-mail address changes because of a merger, move, or ISP failure, or if you just find a better ISP deal elsewhere, no problem. Just call and give us your new home e-mail address and all your wickenburg.us mail will immediately and seamlessly be diverted there!
A wickenburg.us address set up for forwarding service is $15 per year.
Storage service -- We create for you a physical mailbox on wickenburg.us, which you can use in addition to or instead of the one provided by your ISP. (This is also a perfect service for DirecWay subscribers, who get no personal mailbox.).
You use a standard mail client or a public web-mail service to access this mailbox from your home ISP or any other ISP, even on the road.
Mail stored in wickenburg.us mailboxes is screened by SpamAssassin.
A physical mailbox at wickenburg.us is $30 per year.

Both these services will work for you whether you have a Windows PC, a Macintosh, a Linux system... you name it.
