I'm running sendmail 8.13.3 with Sun extensions on a Solaris 8 box.
The Solaris OS was installed with IPv6, although we are only using
it in an IPv4 environment. However, sendmail consistently seems to
retrieve both AAAA and A records for envelope domains. This seems
inefficient to me. I've modified the sendmail.mc file so that
sendmail no longer listens on an IPv6 port, but it still requests
the AAAA records.

Am I incorrect that AAAA records are useless in my environment?
If so, how do I get sendmail to quit asking for them?

In article <d26tk1$gma$1...@usenet.cso.niu.edu>,
Thanks for the response. I realize I can compile sendmail
without IPv6, but I'm using a pre-compiled package (from
CSW/blastwave), at least on the Solaris boxes. I was hoping
that there would be a tweak to the .mc file (like the '-4'
arg does for bind named) that effectively turns off this code.
