You can access mail from a Zimbra account using IMAP or POP3. This option is available to both Open Source users and Network Edition customers. Note: This method only syncs mail messages. For access to contacts and calendars, use the Zimbra Mobile Webclient.
- Under Mail settings, select "Add Account..."
- Select "Other"
- Select "IMAP", "POP3", or "Exchange"( Select IMAP for Rider email)
- Fill in the "Name", "Address", and "Description" fields
- Provide "Host Name", "User Name", and "Password" in the "Incoming Mail Server" section. The iPhone will automatically detect IMAP over SSL if your server requires it. If your server requires a non-default TCP port specification, use the hostname:port format in the "Host Name" field. SSL settings can be adjusted later under the "Advanced" section in the mail account settings.
- In the "Outgoing Mail Server (SMTP)" section, provide settings for "Host Name", "User Name" and "Password". As with the incoming mail server, the "Host Name" setting accepts the hostname:port format if the outgoing mail server uses a non-default TCP port.
- Save the configuration
