Well, besides the aspect of software availablilty, it is a a matter of
knowing the message id of the mail to which you want to refer.
Then you have to put it into a "In-Reply-To:" header or a "References:"
header.

The message ids are providently shown in the debian-user archive.
See
  https://lists.debian.org/debian-user/2019/10/msg00127.html
  Message-id: <[?] [🔎] E1iFl97-0002sw-8y@joule.invalid>

The string "[?] " is an artifact of copy+paste between web browser and
text editor. Your reply's headers should look like:

  References: <[🔎] E1iFl97-0002sw-8y@joule.invalid>
  In-Reply-To: <[🔎] E1iFl97-0002sw-8y@joule.invalid>

"References:" can take multiple ids separated by blanks and optional
newlines. Kindof a thread branch history.
Like:
  References: <[🔎] E1iFYNs-0000eT-Eo@enotuniq.net>
   <[🔎] E1iFjk3-0002Hf-FQ@joule.invalid>

"In-Reply-To:" can take only one id.

Now it depends on your mail client whether you can talk it into accepting
one or both of these header lines, ot the message id so that it composes
own reply headers.


Have a nice day :)
