Ini problem khas user yang pakai koneksi Biz.net.id (dan link.net.id) yang memblock DNS query ke public DNS.
Dampaknya sender host time out.
Tunggu saja resent dari sender host itu.

Rasanya mereka sudah mulai insyaf deh, membolehkan query ke public DNS local Indonesia.
Coba di test dari MDaemon server.

c:\ nslookup -t txt xiangyu.cn 203.119.13.77
c:\ nslookup -t txt xiangyu.cn 203.119.13.78

kalau hasilnya mirip dibawah ini, boleh tambahkan IP 203.119.13.77/203.119.13.78 kedalam MDaemon DNS query.

http://mdaemon.dutaint.co.id/mdaemon/23.0.1/default-domain-and-servers_dns.html

Manually configured DNS servers

$ nslookup -q=txt xiangyu.cn 203.119.13.77
Server:         203.119.13.77
Address:        203.119.13.77#53

Non-authoritative answer:
xiangyu.cn text = "v=spf1 include:spf1.mail.xiangyu.cn include:spf2.mail.xiangyu.cn include:spf3.mail.xiangyu.cn -all"
