The *postfix* role will now generate configuration and a lookup table
for [canonical address mapping][0] of email recipients. To configure
the mapping, the `postfix_recipient_canonical_map` must be a dictionary
of source-target addresses, e.g.:
```yaml
postfix_recipient_canonical_map:
my.bad.email@fake.test: my.real.email@example.com
```
