I agree. This makes it easy to make sure domain names are unique.

I think we still need it. The 'real' domain is the one that has a file
system behind it, and we need to know which one it is. I suggest a
pointer field real_domain containing the domain_name_id of the real
domain. [Isn't there something in mailing lists that ties the list to
the real domain, that makes renaming domains hard?]
We can save a little bit of space by storing the path to the domain
directory in the domain table, and only the path from there down in the
users table. The dir field in the users table should be renamed to
user_dir.
I think domain_alias should be renamed to domain_names. Is there a
better name for domains now?

How about we remove the NOT NULL constraint from each of the limit
values, and if they are null take the value from the 'domain'
_system.default. This way if you leave any value NULL, the default is
filled in from the database in a single query:
SELECT b.domain as domain,
c.domain as real_domain,
if( a.ip_address IS NULL, e.ip_address, a.ip_address ) as ip_address,
if( a.max... IS NULL, e.max..., a.max... ) as max...,
...
FROM domain_names a
LEFT JOIN domains b USING( domain_id )
LEFT JOIN domain_names c ON c.domain_id = b.real_domain
LEFT JOIN domain_names d ON d.domain = '_system.default'
LEFT JOIN domains e ON e.domain_id = d.domain_id
WHERE a.domain = '$TargetDomain';

OK.
I also added a sequence field to the valias table.
