I changed getipnodebyname to obey ip6addrctl in years past.  I read
RFC 2553 again, and realize that it mentions IPv6 addresses are
returned 1st.  So, my past change might be bad thing. X-(
However, I'm still curious about use of AI_ALL in sendmail.  As far as
I read the source of sendmail briefly, it seems the usage doesn't
depend on AI_ALL.

Sincerely,
