I am using Nokia Lumia 638 4G with Windows Phone 8.1. I have configured 2 email accounts in the email client: an Outlook account (live.cn) and a Zoho account (with my own domain name). The Outlook inbox works well, but the Zoho inbox cannot display email correctly.
An example is as follows. A plain text email with 8 lines (4 text lines and 4 blank lines between them) are sent to these 2 accounts.
It looks well in the Outlook inbox:
But it looks bad in the Zoho inbox (the first line is missed, and some source code are shown):
Meanwhile, the Zoho account works well with Android's email client and Claws-mail in Windows/Linux. The emails can be displayed correctly in these clients.
