[S-mailx] Read message N on stdout?

[Morten Bo Johansen]

Hi,

I have aliased the following command to show the headers of all
unread messages in my inbox

  mail -L :u -f imaps://mail.simply.com

The output may look like

  U 23 MitID              2023-01-20 11:27     /10349 Ordrebekræftelse 588215 -

So I would like a command that would send the contents of this
message to stdout, so I do not have to enter interactive mode
to read it. Can I do that?

If that is not possible, can I have a command which in one fell
swoop enters interactive mode, selects the message I want to
read (here, no. 23) and show its contents?

Thanks,
Morten
