Re: sendmail error, "MX list for mydomain.com points back to server.mydomain.com"

Yes.

I tried turning on -d8.10 and got the following output at startup,
which I can't interpret...

I don't understand the 0 answers and NXDOMAIN at all
It's not clear to me where all that is coming from, as strings like 
res_send()
don't seem to appear in the source.

Also, that only prints at startup; apparently it doesn't go through the 
domain.c code
for delivery to a localhost, even though I get that error message back.

Can anyone tell me / point me to how to build sendmail from the code in
/usr/src/contrib/sendmail ?

Thanks,
