Email service switch is very smooth.
And user interface is same as Gmail, friendly.
One issue found. I send an email to an email address ended by 163.com.
The Delivery Status Notification (Failure) message said:

SPF record for your Email server

If you have your own email server like me, you may need to know something about SPF record.
From the SPF website, I got the following description:
SPF fights return-path address forgery and makes it easier to identify spoofs.
Domain owners identify sending mail servers in DNS.
SMTP receivers verify the envelope sender address against this information, and can distinguish authentic messages from forgeries before any message data is transmitted.
Use DNS Stuff‘s DNS report tool, you can see if your email server has a SPF record.
