If you move your email to Gmail you will get:
- Gmail’s renowned interface as your webmail, but at http://mail.yourdomain.com
- POP3/IMAP/SMTP access (as before), but now using Google’s servers
- Awesome performance, reliability and spam filtering
- The option to add your own logo to the Gmail web interface
You will normally still use DreamHost for everything besides email, but you can even change your domain to use pages.google.com for its main website, which would actually imply that you no longer would be using DreamHost for any services.
I would love to hear some feedback in the comments, if you already have switched your mail to Gmail.
