system mail not sending

I use CLoudFlare as the DNS and have the mail.domain pointing corectly but system message as well as local messages send fromt he websites forms via php/ jq arent getting recevied. Am i missing a step to get these message to send? We use Google G Suite for our email its just for the system messages and local message from the websites. With VestaCP it worked out of the box without issue but on CWP i cant find whats missing

I use CloudFlare as DNS too and email works fine. Some thoughts below for you.

• Make sure MX entry in CloudFlare has grey cloud (DNS only)
• Have you successfully set up rDNS
• Have you  set up DKIM & SPF and added matching entries to CloudFlare (this is not essential but recommended to keep your emails out of spam filters)

Hi there,

onCloud flare the MX points to G Suite and also mail.domain.com is pointing to our CWP IP address. We also have the G Suite DKIM and SPF records set up. As we dont use hte local mail for anything but sending system message and submition to ourself from different websites this is what the rDNS is showing

Your rDNS for IP "I.P. h.e.r.e" is set as following:


resolves to:
l.root-servers.net.
j.root-servers.net.
b.root-servers.net.
e.root-servers.net.
m.root-servers.net.
a.root-servers.net.
h.root-servers.net.
k.root-servers.net.
i.root-servers.net.
g.root-servers.net.
c.root-servers.net.
f.root-servers.net.
d.root-servers.net.
