Server hotmail.com yang memblock koneksi dari IP 180.250.59.246, karena pakai
multi PTR record sehingga diragukan validitasnya.

Multiple pointer records

While most rDNS entries only have one PTR record, DNS does not restrict the
number. Multiple PTR records are used, for example, when a web server supports
many virtual hosts— i.e. multiple hostnames then resolve to a single address,
and multiple hostnames will be returned for a PTR lookup for that shared
address. However, DNS lookups typically occur over UDP, and since UDP has a
limited message size, in extreme cases, multiple PTRs could cause a DNS response
to exceed those UDP limits.
---

$ host 180.250.59.246
246.59.250.180.in-addr.arpa domain name pointer mail.ciputrahospital.com.
246.59.250.180.in-addr.arpa domain name pointer mail.ciputra.co.id.

Perbaiki PTR recordnya menjadi satu saja.

246.59.250.180.in-addr.arpa domain name pointer mail.ciputra.co.id

dan di domain manager ciputrahospital.com di set smtp hostname = 
mail.ciputra.co.id.

http://mdaemon.dutaint.co.id/mdaemon/17.5/index.html?domain-manager_host_name_ip.htm

setelah itu request delist ke hotmail.com melalui webform berikut

https://support.microsoft.com/en-us/getsupport?oaspworkflow=start_1.0.0.0&wfname=capsub&productkey=edfsmsbl3&locale=en-us&ccsid=635714983457075069

Adjust idle time out untuk DNS query karena terlalu singkat, naikkan 6 kalinya.

http://mdaemon.dutaint.co.id/mdaemon/17.5/index.html?default-domain-and-servers_timouts.htm

Wait 60 seconds for MX responses
Wait 60 seconds for A/ responses

mereka yang memblock IP kami ya pak? Lalu solusinya seperti apa pak? Terima 
aksih.
