There are 3 ways to host a website at your personal domain when you have Pobox managing your email:
It's easy to have us handle your mail, and keep your site where it is. You just need to set up a personal domain, then ask your provider to update your MX records.
Your MX records only update where people send mail, so any other services you have set up for your domain (like your website) will not be affected by Pobox handling your mail.
If you are looking for a web provider, some providers that let you update your MX records are:
If you would like your personal domain to go to a blog or other hosted web service, then setting up an A record or CNAME with us is simple. Just go to the Personal Domain page, and enter the CNAME or A record your service provided into the "Web Redirection using DNS" box.
If you have a web page on a service that doesn't provide A records or CNAMEs for personal domains, or you'd just like to point the web page for your personal domain to another domain you own, you can also redirect your domain to a web page. Just Just go to the Personal Domain page, and enter the web page you'd like us to point your domain to into the "Web Redirection using a URL" box.
