Here, SMART_HOST is defined as relay:uucp-gateway (meaning send to the host
uucp-gateway withth e relay delivery agent). The LOCAL_NET_CONFIG then
introduces a rule that causes all names that end in your domain name ($m) to be
delivered via the smtp delivery agent. Any other addresses fall through and are handled
by the SMART_HOST rules.
In ?§19.5 on page 696, we deal with the flow of rules through the parse rule set 0. For
now, merely note that LOCAL_NET_CONFIG fits into the flow of rules through the
parse rule set 0 like this:
1. Basic canonicalization (list syntax, delete local host, etc.)
2. LOCAL_RULE_0 (?§17.3.3.2 on page 596)
3. FEATURE(ldap_routing) (?§23.7.11.22 on page 922)
4. FEATURE(virtusertable) (?§17.8.59 on page 645)
5. Addresses of the form ???user@$=w??? passed to local delivery agent
6. FEATURE(mailertable) (?§17.8.28 on page 629)
7. UUCP, BITNET_RELAY (?§21.9.11 on page 808), etc.
8. LOCAL_NET_CONFIG
9. SMART_HOST (?§17.3.3.6 on page 597)
10. SMTP, local, etc. delivery agents
17.4 Masquerading
Masquerading is the process of transforming the local hostname in addresses into
that of another domain. This results in the mail message appearing to come from
that other domain rather than from the local host. Masquerading is most often used
