Possible? Yes.

I'm not aware of anyone actually doing it but I would approach it from  
one of these methods --

- use procmail/maildrop to pipe the incoming message through a script  
that parses the body format you've chosen and submits an appropriate  
PROCESS_SERVICE_CHECK_RESULT external command.  http://www.nagios.org/developerinfo/externalcommands/commandinfo.php?command_id=114 
. I expect this could be a pretty straightforward perl script.
- write a script that parses the mailspool or checks the POP/IMAP  
account and submits an appropriate PROCESS_SERVICE_CHECK_RESULT  
external command.

Of the two, the first seems easiest/best...
