-Qmail IPv6 patch
- Kazunori Fujiwara <fujiwara@pyon.org>
- originally 1997,1998
- 2002 Oct. 6.
-
-This patch enables qmail to receive and send mail via IPv6 network.
-
-This patch was not guaranteed.
-The fault by having applied this patch belongs to one which applied the patch.
-
-apply this patch and defines some macros on conf-cc.
-INET6 (default) enables IPv6 transport
-TCPTO_REFUSED when enabled, tcpto denial cache caches
- connection refused hosts.
- (normaly, timeout only)
-
-patch needed part:
-
-DNS Resolving:
- o resolve AAAA with A
- o IPv6 address reverse resolve.
- o resolve MX's AAAA and A
-
-Receiving:
- tcp_env resolves IPv6 and IPv4 socket address to environ.
-
-Sending:
- A and AAAA are also resolved.
- IPv4 address and an IPv6 address are treated similarly.
- tcpto denial cache caches IPv4 and IPv6 addresses.
-
-
-You need IPv6'ed inetd and tcp wrappers.
-
-You want to use IPv6 only life, You need OSs which have IPv6 resolver
-like *BSD.
-
-
------
-Changes:
- I found my old patch's tcpto bug on 2002 Oct. 6.
- Older patch's tcpto is not work.
- without dinial cache, sending mails works.
- but some useless connects increase.
-
-
-Please inform me something wrong with this patch and this text.
