postfix mail domains

[kilburn]

There are two approaches to address verification for relayed domains:

1. Use postfix address verification
2. (my preferred one) Implement an interface to allow the domain owner (client) to specify it's valid addresses. IMHO it would be enough if we create a "php rpc" that accepts user credentials + list of emails and processes the list (probably sanitizing + inserting it to the db), in combination with a backend perl script that writes the actual config.
