I can't think of a screenish way to do what you're talking about.
If you use zsh as your shell, consider using the periodic ()
function to execute your program. In your checkmail program, include
a bell (^G, I think) in its output. That will cause screen to
display bell_msg, which you could configure to say 'You've got mail'
or similar.

IIUC, this could only be used to alert you to the presence of new
mail (assuming checkmail produces output only when it sees mail).

Could checkmail instead be a script which didn't loop, but instead
simply checked your mailbox? Then, using screen, you could run the
script every few minutes. I do a similar thing in my hardstatus with
regard to my laptop's battery; it's a simple script that polls ACPI
and, if the value of the parsed ACPI data is < 98, displays the
percentage left on the battery. If it's greater than 98, nothing is
displayed. Each time the backtick is run, if it produces output (ie,
if you have new mail), it can display that, otherwise it displays

To do this, use the conditional braces screen provides:
    hardstatus alwaysmessage %?[%1`]%?

I include the square brackets only for visual clarity -- they are
syntactically unnecessary.
