[PATCH] rblsmtpd.c: don't use a the default rbl.maps.vix.com if run without -r switch. rbl.maps.vix.com is obsolete, so don't use it as default rbl if run without the -r switch; default to no rbl instead.
Make upstream build system respect $(DESTDIR) Upstream build system does not make difference between installation prefix (named HOME by upstream), embedded in compiled software, and installation root $(DESTDIR), making staged install, employed by most package managers impossible. . This patch adjust upstream Makefile to respect $(DESTDIR) variable. To configure prefix, use `conf-home' file.
Show the compiler and linker invocations during the build If the "V" environment variable is set to the value "1", show the compiler and linker commands before running them.
