Hi Friends, We are trying to install a fortigate firewall on our network to protect email servers. Our email server was configured on a private ip and one to one NAT map in the firewall. After setup firewall, firewall team to put private dns like firewall router ip in server. We are unable to receive emails after configuring router ip and our isp dns ip in our server.
Sample below for smtp log /var/log/qmail/smtp/current CHKUSER accepted sender: from <u...@example.com::> remote <outlook.com:unknown:XX.XXX.XX.XX> rcpt <> : sender accepted Empty showing in rcpt<> After the fallback firewall it is working fine like rcp <x...@xxx.com> found an existing recipient and got delivered. my tcp.smtp below 127.:allow,RELAYCLIENT="",RBLSMTPD="",NOP0FCHECK="1" Appreciate any one who helps me. -- *Regards,Manikandan.C*
