Mohon tidak posting dengan top posting style di milis ini, selalu
gunakan bottom (interleaved) posting untuk memudahkan pembacaan.

https://blog.joelesler.net/2009/12/bottom-posting.html

The particular part to pay attention to is in RFC1855 --

"- If you are sending a reply to a message or a posting be sure you
summarize the original at the top of the message, or include just
enough text of the original to give a context. This will make
sure readers understand when they start to read your response.
Since NetNews, especially, is proliferated by distributing the
postings from one host to another, it is possible to see a
response to a message before seeing the original. Giving context
helps everyone. But do not include the entire original!"

http://daringfireball.net/2007/07/on_top

The fundamental source of poor email style is the practice of quoting
the entire message you’re replying to. If that’s what you do, then it
doesn’t matter whether you put your response at the top or bottom. In
fact, if you’re going to quote the entire message, top-posting probably
is better. But both are poor form.

Writing an email is like writing an article. Only quote the relevant
parts, interspersing your new remarks between the quoted passages. Don’t
quote anything at all from the original message if you don’t have to.

Does it take more time to edit the portions of quoted text included in
your reply? Yes. So does spell-checking and proofreading. It also takes
time to shower and brush your teeth each day.

Hanya bottom replies yang bisa memanfaatkan inline reply dalam diskusi, top posting itu mirip SMS (Short Message Services) atau Messenger chat hanya untuk 1 topik saja

https://en.wikipedia.org/wiki/Posting_style#Interleaved_style)

Agar outlook bisa otomatis menggunakan Internet Quote Style yang diperlukan saat inline reply maka ubah settingnya seperti ini

https://www.slipstick.com/outlook/email/to-use-internet-style-quoting/

Salin selected text yang akan di quote ulang, yang sesuai contex, ke atas
signature lalu hapus quote text yang mulai dari baris "-----Original Message-----" kebawah s.d Subject: xxxx

Untuk memangkas (hapus) text hanya perlu ketangkasan menggunakan mouse dan atau keyboard.

Setelah kami coba kirim email kembali ternyata masih sama errornya, jd memang kemungkinan settingan mrk yg masalah ya pak.


Sebenarnya bukan di mereka (pemilik mail domain @collins.com), tetapi ISP yang Anda pakai melakukan DNS hijacking (DNS redirecting) sehingga hasil resolvenya salah.

Hal itu dilakukan oleh ISP terhadap corporate connection atas perintah MenKominfo yang baru, yang menginterpretasikan aturan lama perihal Internet Positive (Internet Sehat), dan mengganggap bahwa domain collins.com adalah "situs pornography atau situs terorism".

https://www.imperva.com/learn/application-security/dns-hijacking-redirection/


https://www.kominfo.go.id/content/detail/3303/internet-sehat-dan-aman-insan/0/internet_sehat

dan kelihatannya pemilik/pengelola domain @collins.com (akhirnya) mengetahui hal itu sehingga membuatkan domain baru @collinsaerospace.com sebagai penggantinya. Tetapi dia baru sempat mengubahkan untuk portal web belum untuk email nya, coba lihat

https://www.collinsaerospace.com/what-we-do/service-and-support/support

terlihat rujukan emailnya masih @collins.com

Singkatya, coba kirim mailnya ke ben...@collinsaerospace.com.
Dugaan saya mail tersebut akan di redirect ben...@collins.com

==============

Teknik DNS hijacking ini lebih canggih dibanding DNS blocking (block tcp/udp port 53) yang pernah diterapkan beberapa ISP di tahun 2013 - 2017 yl.

DNS A record collins.com diredirect ke IP 103.169.16.2 milik ISP (masing-masing ISP, dhi lintasarta.net.id)

coba lihat ke http://103.169.16.2/.
Disitu terlihat perihal internet sehat Kominfo.

dirumah saya pakai koneksi myrepublic sehingga A record collins.com diarahkan ke IP milik myrepublic.net.id, sekalipun dnsquerynya ke public DNS.

$ host -t a collins.com 1.1.1.1
Using domain server:
Name: 1.1.1.1
Address: 1.1.1.1#53
Aliases:

collins.com has address 103.47.132.195

Tetapi kalau saya pakai koneksi di server IDC gedung cyber 1 hasilnya akan berbeda.

DNS hijacking/redirecting ini hanya bisa ditembus pakai DoH (DNS over http), yang sayangnya belum disupport oleh MDaemon versi terkini.

https://en.wikipedia.org/wiki/DNS_over_HTTPS

Kalau Anda bisa vote ke MDaemon developer mestinya akan membantu mempercepat disupportnya DOH.

Lihat contoh berikut di PC rumah saya.

pakai normal dnsquery hasilnya gagal
$ dig mx collins.com @8.8.8.8
