I have created 2 email ids with hosting provider. Now, I want to add MX records to CloudFlare. But my hosting provider is telling me that there is no need to add MX records, just add A records and reset MX records to default (if they were changed). Do you think adding MX records is not required ? Would my mails still be routed through CloudFlare if I add only A records to point to Hosting server ? If it is to, I would like to know the default MX setting at CloudFlare so that I can reset MX records. Thanks!
Cloudflare does not proxy mail, just http/http(s) traffic. https://support.cloudflare.com/hc/en-us/articles/200169156-Which-ports-will-Cloudflare-work-with-
You should have Mx records that point to wherever your mail server is; I’d recommend verifying what your Mx records should be. In general there’s no need to change the Mx records when migrating to Cloudflare for DNS.
