Amavisd requires all domain entries to be prefixed with an `@`.
Plus, all email entries would contain an `@` too, so this enforces that
requirement.  Otherwise it's possible to create a domain wblist that
doesn't start with an `@` which is completely + silently non-functional

before we handed over domain_name instead of domain_id to the checkDomainModuleDomain function,
which resulted in nothing. This fixes the call by querying the database for the domain_id for
the given domain_name.

1 letter and has to be between 1 and 63 characters long.

before the regex matched empty entries and entries starting with a number.
