Yes and no. Yes, its a human problem... My problem in that our support staff get hit with "Why cant I email my when can."... So yeah, its my problem. It would be lovely in a perfect world if people cleaned up their DNS. But some people dont know how, some people have made honest mistakes. Either way, its pretty well a pointless exercise try to explain to the end user what a LAME delegation is. Its a software problem in that it has yet to be documented or I have yet to find the documentation, explaining when this behavior has changed. Someone mentioned that it started happening between P5 and P7 of BIND which sounds plausible. But there were also sendmail changes during that period as well, and the tuneable in sendmail # name resolver options #O ResolverOptions=+AAONLY does not seem to have any affect. I cc'd the FreeBSD sendmail maintainer a while back for his opinion, but have yet to hear from him. ---Mike -------------------------------------------------------------------- Mike Tancsa, tel +1 519 651 3400 Network Administration, mike@sentex.net Sentex Communications www.sentex.net Cambridge, Ontario Canada www.sentex.net/mike To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
