Im having an rDNS mismatch problem, I’ve asked my host what they think by they suggest disabling cloud flare, which I would rather not do considering things are working pretty smoothly other than this issue.
I use hostdime for hosting, GSUITE as my email provider and cloudflare for DNS.
When using mail tester I get two dings.
RDNS_NONE Delivered to internal network by a host with no rDNS This may indicate you do not have a rDNS configured for your hostname or the rDNS does not match your sending IP
I am able to change my PTR record in my hosting dashboard but it seems to do nothing to the “unknown” part of my email header nor does it get spam assassin to simmer down about the rDNS.
Is posting an email header safe?
Your message is not signed with DKIM
I have a valid DKIM record from gsuite, it is added into cloudflare records correctly I believe. Gsuite dkim setup tool tells me I am being authenticated, so why are the messages coming through with no DKIM signature?
I have read many many forum posts about these issues for the past couple of weeks before posting, but I keep going round and round. A little help would be very very appreciated.
Are you being authenticated as a user over SSL for GSuite? What is the DKIM header response in the e-mail message when sending mail to yourself or some other account owned by you (for example basic Gmail account)?
Do you also have an SPF (TXT) record and an DMARC added to your domain at your Cloudflare account?
Hm, thanks for feedback information.
At least, if recently added and setup, you should give it 24 hours to work from when you set this up.
The easiest way is to send a message from the email account you set this up for to another email service, preferably a reliable service that checks these records.
With the received email you’ll need to “view source”, “view headers”, or “view raw message”.
This will show you a lot of confusing looking text, but you’re looking for something like this.
If you see any failures you’ll need to do some problem solving. The list below contains excellent tools/websites to help diagnose email issues, for example checking if records exist, but at this point you may need to engage the services of a professional who really understands this area:
ip4:184.108.40.206 indicates to me that you are also using your own host/origin IP to send/receive some emails.
In that case, using DKIM/SPF for Google Suite but sending/receiving some mail from your host/origin, maybe you would need to add an A record for mail pointing to your host/origin and SPF and/or DKIM (TXT records) for that too?
