The .com domain is configured for Google’s mail servers. If this is not correct, you need to contact your mail provider and clarify what you need to configure. Refer to Manage DNS records · Cloudflare DNS docs on how to configure this on Cloudflare.
Also, the IP addresses you have configured in there won’t work as they are Cloudflare addresses. You need to configure the correct ones. Different issue of course.
Knowing that the DNS servers are managed by your services, could you make the changes to the MX DNS zone. I enclose the MX OVH After the modifications, when will the MX be operational with OVH messaging?
Originally, I did not have a CLOUDFLARE account. I created one this morning, I went to look for the domain name seipam.com to make the changes. I don’t know what else to do?
Well, the domain is active on a Cloudflare account and not the one you posted. So maybe someone else configured that. You should reach out to that person.
As long as the nameservers were not updated, none of the settings will work.
Best to contact whomever manages your domain and clarify what the right settings and accounts for the domain are.
