How do I connect to my email account?

We have 3 methods of connecting to your email account hosted with us. They are:

Webmail Interface, this interface supports not only mail but all groupware features such as Address Books, Calendars, Tasks, Notes, and Journals

IMAP. With any email client, simply add an IMAP account in your email client using
Incoming IMAP server
Outgoing SMTP server
Username
Password

POP3. With any POP3 client like outlook express or thunderbird you can send and receive emails straight from your computer.
