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.
