AFAIK if you have mail already configured in general (not for Emacs), then `M-x
report-emacs-bug' will prepare the mail content, subject, and destination, and
then call up your mail client.

E.g., on Windows, I use Outlook as my mail client, and `M-x report-emacs-bug'
causes Outlook to open a new message. I then hit `C-v' to paste the bug-report
content (automatically saved to the clipboard) into the message body.

Even if you do not use Emacs for mail, `M-x report-emacs-bug' can help, because
it puts you in an editing buffer where you type your bug report, and that buffer
already has a bunch of important info that can help the Emacs developers.

E.g., it shows exactly what your Emacs build is (hence which Emacs version and
which platform), and it lists a bunch of variable values that might be
pertinent.

So you can just use `M-x report-emacs-bug' to get that data, and then paste it
into an email message, if you like.  You definitely need not configure or use
Emacs for email.
