First! I set my shopify store with its records A and CNAME (so my domain is hosted in shopify) so far my site is working.
Second! I have a mail hosting from another provider which a need to set up Dns, so I´m not sure if I did it right because I still have problems with it and can set my email accounts on outloook and their not working because it´s not pointing to the mail server. Please if anyone can help me and give clue to solve it.
Assuming the IP of the A record for ‘mail’ is correct, the only change I can see immediately that you probably need to make, is to switch that record from to .
Cloudflare does not proxy mail services, hence why it needs to be set to . Also make sure that any email services connect over the subdomain, i.e. mail.yourdomain.com rather than yourdomain.com.
