If you want to excuse this behavior, compile sendmail with -D_FFR_WORKAROUND_BROKEN_NAMESERVERS and add WorkAroundBrokenAAAA to your= ResolverOptions setting. However, instead, we recommend catching the problem and reporting it to the name server administrator so we can rid t= he world of broken name servers.
