With this, the Postfix SMTP server will accept mail for non-existent
users, the Postfix queue will fill up with bounce messages, and
your system will be banned because it sends backscatter email.
Instead of deleting the default setting
local_recipient_maps = proxy:unix:passwd.byname $alias_maps
remove the dependency on the proxymap service.
