If you're just doing that for testing, fair enough, but if you want
per-supplier addresses to give out without needing to pre-configure
things and not wanting a general wildcard address, you're much better
off using suffixes.

For exim, IIRC you do that with the local_part_suffix setting, allowing
you to give out addresses e.g. for a supplier called 'gllug':
