For instructions on configuring your email, refer to the setup instructions inside our CMS, under "Domains and Email", then click the Email @ symbol, then the mailbox in question to view step by step setup instructions. You can configure your iphone, or other mobile phone, notebook, desktop etc to all read the same inbox.
Webmail and IMAP clients will read only the emails in your inbox. They will not have access to the full history stored on your computer. They do not store your outgoing emails. Although there might be a desire to use webmail long term, please be aware that we have storage limits, and therefore webmail is designed to only be used for a few weeks at a time, with your primary email storage being on your computer or own exchange server. If you require a more powerful webmail service, we suggest you change to using google apps.
