Hi guys, i setup a new email server and i get the following error when i sent an email Code: host gmail-smtp-in.l.google.com[2a00:1450:400c:c0b::1b] said: 550-5.7.25 [2a02:c207:2024:1421::1] The IP address sending this message does not 550-5.7.25 have a PTR record setup, or the corresponding forward DNS entry does 550-5.7.25 not match the sending IP. As a policy, Gmail does not accept 550-5.7.25 messages from IPs with missing PTR records. For more information, go 550-5.7.25 to 550-5.7.25 If i understand it right, the ptr record is the reverse lookup and i put that in a right way as i think. the ip is: 167.86.74.26 the server is mx1.cl-i.net I dont understand why google rejects this email. thanks for let me have a hint what i am doing wrong thanks tom
IPv6 PTR today is still the same. Either disable IPv6 in postfix so it can only send mail using IPv4 or change your IPv6 address PTR record (or let the IP's owner/ISP/datacenter do it for you if they don't provide a method to do it yourself)
Hi guys, thanks a lot for your kind help i changed PTR Record IPv6 but the problem is still the same maybe you have any idea how i can solve the problem? thanks in advance for your kind help
If the error still is the IP address does not have PTR record set up, the IPv6 PTR is still missing. If the problem now is something else, please describe the problem.
I don't know how you changed the PTR record but nothing has changed. Your IPv6 address in the first post (2a02:c207:2024:1421::1) still resolves to vmi241421.contaboserver.net Are you sure you can change the PTR record yourself? Simply creating it under zone cl-i.net isn't to right way.
