Postfix 'localhost' in originating email address

h0st.d0main.tld

It seems as if 'h0st' is being dropped and replaced by 'localhost' to render:

user at localhost.d0main.tld

I'm looking to achieve:

user at d0main.tld

~ /usr/sbin/postconf -n reports:

...
inet_interfaces = all
...
mydestination = $mydomain
mydomain = d0main.tld
myhostname = h0st.d0main.tld
mynetworks_style = subnet
myorigin = $mydomain
...
