Don't let authenticated client use arbitrary sender addresses.
The following policy is now implemented:
* users can use their SASL login name as sender address;
* alias and/or list owners can use the address as envelope sender;
* domain postmasters can use arbitrary sender addresses under their
domains;
* domain owners can use arbitrary sender addresses under their domains,
unless it is also an existing account name;
* for known domains without owner or postmasters, other sender addresses
are not allowed; and
* arbitrary sender addresses under unknown domains are allowed.
