Presumably because Exim isn't working, so you're testing to see if you can
reproduce the problem using Swak?

It's complaining about the return address, root@???. It says
that it's not valid, which it's not.
Is there a --from option to Swak, or something like that? Could you try
using a real address as your FROM address?

Could you give us the actual log messages?

If the "hostname" command says "cruncher.domain.com" then a test mail sent
using Exim, if no explicit domain was specified, would often be qualified
as user@???. However this is fully configurable, so please
tell us *exactly* how your website/application is sending the email (what
lines of code and configuration you use to do it) and the relevant parts
of your Exim configuration file (qualify_domain and everything it depends
on).

I think it's the return address, not the HELO, that they're complaining
about. Use a real email address (e.g. your own).
Cheers, Chris.
