Cloudflare for mail supplier

in my domain, accept from the “regular” things, i have mail service. which consist on a mail relay outsource supplier. Do make it work, I needed to configure MX record and txt record for “answers”- PTR record, and several TXT records. Some of them include the ip of the server, and mail relay.
Can I do this kind of records in cloudflare? Will if support the mail relay? If I can’t make it work by myself, will I get support for that?

Thanks a lot…

Cloudflare DNS supports those record types, though the PTR record is generally taken care of by whoever owns the IP address of that server.
