Ini problem koneksi ke DNS resolver.
Penyebabnya bisa karena kanal internet sibuk, tetapi besar kemungkinan karena
outbound TCP/UDP port congestion akibat terblock oleh firewall.
Periksa setting firewall, baik windows firewall, hardware firewall maupun proxy
(antivirus) pastikan outbound TCP dan UDP port 53 diopen.
Lebih baik lagi jika dynamic allocation port (Ephemeral port) untuk outbound
49152 s.d 65535 di open (port range itu adalah standard Windows UDP port/socket
di win7 keatas) agar MDaemon outbound multi session tercukupi winsocknya.
Firewall dan antivirus sudah di disable, tapi coba kirim email masih
tidak terkirim :
