In deliver.c, the following code is found:

        /*
        **  Call the mailer.
        */

        if (ctladdr == NULL)
                ctladdr = &e->e_from;
#ifdef NAMED_BIND
        _res.options &= ~(RES_DEFNAMES | RES_DNSRCH);           /* XXX */
#endif

The resolver options says that gethostbyname should not try to search
for hostname in local domain or parent domain, neither append local
domain if host is a single-component name.

The context of the code implies that the macro $[ host $] doesn't 
expand to host.local-domain while rewriting sender addresses. 

Since this code only executes while delivering a letter, you
may get a bit surprised and baffled by this inconsistency between
mail delivery mode and sendmail test mode (-bt).

Anybody care to comment on the reality on this code?? Any why there's
a lot of 'XXX's :-) Are people depending on this code?? I didn't really
like this code, so I commented it out.
