How To Capture Date Command Output To A Variable.

Greetings,

I have tried searching the list archives, but I did not find an answer,
and neither see this in any documentation that I am aware of.

I am trying to inset the current date (recipe execution date) into the
headers of all incoming email (was asked to do so), and here is the
Recipe.


:0 fhw
| $FORMAIL -A "X-Email-Status: Processed at $DATE"


My question is, how do I capture the output of the date command and
place it in the headers like the above?

I tried 

DATE='/usr/bin/date -R'

But I still get  the header inserted as
X-Email-Status:  Processed at  /usr/bin/date -R

Can this be done?

Any pointers are welcome.

Thank you.
