Feature: the SMTP client now falls back to native name
service lookups (including /etc/hosts) when a host cannot
be found in the DNS. This is controlled by a new parameter
smtp_host_lookup (default: dns, native). Files: smtp/smtp.c,
smtp/smtp_addr.c.
Open problems:

Support for sending mail to hosts not in the DNS, without having
to turn off DNS lookups. The "smtp_host_lookup" parameter controls
how the Postfix SMTP client looks up hosts. The default is to use
DNS and then the native mechanism. See conf/sample-smtp.cf.
