US.EDU) instead.
Ordinarily, this transformation is not automatic. Each username that is to appear to be
from the firewall machine will need an entry such as that in the User Database (see earlier
example). To automate this process, you can use the special username :default in a
mailname declaration:
:default:mailname Firewall.US.EDU
If a maildrop entry is found for a particular name, but no corresponding mailname record is
found, the outgoing address is ordinarily unchanged. If, however, a default hostname has
been defined with :default, that hostname replaces the local hostname for all addresses
that lack their own mailname entry:
:default:mailname Firewall.US.EDU
bob:maildrop bob@here.us.edu
In this example, the user bob has a maildrop entry but lacks a mailname entry. Outgoing mail
from this user will have the :default hostname used instead of the local hostname. The
user sally, on the other hand, has neither a maildrop entry nor a mailname entry and so will
not have her outgoing address rewritten.

Look up local passwd information V8.7 and later
The user type is used to look up passwd(5) information using the method defined by the
MailboxDatabase option (?§24.9.62 on page 1042). A password entry typically looks like
this:
ftp:*:1092:255:File Transfer Protocol Program:/u/ftp:/bin/sh
