本帖最後由 losiuhoi 於 2015-4-14 12:08 編輯

我想係NAS度set一個SMTP server
但係send唔出email

用mxtoolbox.com去check
佢話
SMTP Reverse DNS Mismatch         Warning - Reverse DNS does not match SMTP Banner

即使我加多兩條record都係同一個問題,定係我set錯左?

    Reverse DNS 要係 ISP 層面做, user 自己點指都做唔到的, 人地果 d 要 lookup 個 ip 唔洗睇 dns resolve 直出 server name 果 d
