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
