-d8.8
Resolver debugging Debug command-line switch
The -d8.8 debugging
switch causes the resolver library to be put into
debugging mode (if that mode was included when that
library was compiled). The ResolverOptions option (ResolverOptions on page 1080) +DEBUG
also turns on this debugging mode. But be aware that
turning on +DEBUG will cause a large number of
screens full of output to be produced by the
resolver library for every DNS lookup.
If the name server returns an answer to an MX lookup,
and if the answer is not an MX record or an error,
sendmail will skip that host.
The -d8.8
debugging switch (or the resolver library being in
debug mode) then causes
sendmail to print the
following:
unexpected answer type wrongtype, size bytes
The wrongtype is an integer that can be found in <arpa/nameser.h >.
