The envelope is constructed from those headers when you use -t:
ordinarily, they would be taken from other parameters passed to Exim on
the command line.

Are you trying to validate local recipients or others?

Are you planning to reject the entire message if one recipient is wrong?
I suppose you could use Exiscan's fakereject feature, so that you could
pass back an error message but still deliver to the other recipients.

You should be able to do what you want by with the $recipients variable.
For example, you could use ${perl{}} or ${run{}} to pass $recipients to
a perl function or external script to validate them. If a particular
return value were given, you could then use fakereject to pass details
back. This would be a little complex and don't ask me for details as I
have a stinking cold atm and can't think clearly.
Slightly easier might be to make more use of Exiscan. You could write
your own filter script to parse an e-mail and verify recipients and then
configure Exim+Exiscan to think that it is a cmdline virus scanner.
Verification errors would be passed back in $malware_name.
