Can we get display name support

[bernadinm]

Is your feature request related to a problem? Please describe.
This pop cli works but is missing a feature where we need to ensure the proper display name is configurable. At the moment, when the email is received from this client, it shows up on the recipient's inbox as the alias name of the email. If you can perhaps use a display name flag such as -d <name of person> this will be easily seen at a glance in the recipient's inbox.

Describe the solution you'd like
If we can add support for --display-name, -d that would be useful.

Describe alternatives you've considered
I attempted to control the display name from the email exchange provider, however, it is ignored from pop.

Have you tried something like this?

pop < message.md \
    --from "Example Name <[email protected]>" \
    --to "[email protected]" \
    --subject "Hello, world!" \
    --attach invoice.pdf
