Documentation: typo fixes by IKEDA Nozomu.
20040616
Bugfix: one missed variadic argument list fix. Victor
Duchovni, Morgan Stanley. File: global/verify.c.
Bugfix: the resolver client cache should be context dependent
because address verification probes may use a different
route than normal mail deliveries. File: global/resolve_clnt.c.
Safety: added similar context dependence to the address
rewriting client in order to avoid trouble when Postfix is
changed. File: global/rewrite_clnt.c.
Bugfix: space in HELO commands could end up in XFORWARD
commands. File: smtpd/smtpd.c.
Open problems:
Low: make sure CCARGS -I options come at the end.
