Email Routing got '550 5.1.1 Domain does not exist‘ error

I have test Email Routing ,before this,I used 163 mail ,it works well.
when I move to Email Routing ,I got this error:
Remote Server returned ‘550 5.1.1 Domain does not exist’

After remove all old email dns(网易免费企业邮--帮助中心), Let Email Routing automatically create the required dns records . It works well.
This topic is report bug.

If only change content ( from v=spf1 include:spf.163.com ~all to v=spf1 include:_spf.mx.cloudflare.net ~all)

I will get error:
Remote Server returned ‘550 5.1.1 Domain does not exist’
