Yes, it certainly makes sense to me. One problem is explaining it to customers. What I _dont_ understand is the different behavior. If more sites were running the same rev of BIND that FreeBSD does now, then the offending site would fix the issue. i.e. why does LINUX and its sendmail and BIND work when FreeBSD and its BIND do not... Or why is LINUX 'broken' and FreeBSD being more 'correct'. ---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
