However, If this server also receives mail from the internet, a
more subtle solution is needed. 

The above would accept mail for any recipient in fd.com. That
would be wasteful. 

The example below overrides the default local_recipient_maps setting
(local_recipient_maps = proxy:unix:passwd.byname $alias_maps) which
would accept too much.

/etc/postfix/main.cf:
    mydestination = fd.com, localhost, ....
    alias_maps = hash:/etc/aliases, static:/dev/null
    local_recipient_maps = proxy:unix:passwd.byname hash:/etc/aliases

/etc/aliases:
    root: someone@somewhere
    abuse: someone@somewhere
    ...etc...
