After seeing these: postfix/smtpd[14497]: warning: 118.71.107.14: hostname adsl-dynamic-pool-xxx.fpt.vn verification failed: Name or service not known postfix/smtpd[14497]: connect from unknown[118.71.107.14] postfix/smtpd[14497]: NOQUEUE: reject: RCPT from unknown[118.71.107.14]: 550 5.1.1 <d...@dd.lv>: Recipient address rejected: User unknown in virtual mailbox table; from=<d...@dd.lv> to=<d...@dd.lv> proto=SMTP helo=<adsl-dynamic-pool-xxx.fpt.vn>
