Hi Zhang,
Thanks for the tip. I just newly setup. try send one to qq.com doesn't work. but 163.com is ok. I have valid pass spf and dkim record using online tools.
I check no blacklist IP
I notice the email recive at my side mail.xxxx.com(127.0.0.1) <-- how to change to real server IP? or is it because of this, it reject?
Any more advice?
Thank you
Kenny
