Subject: Re: How common is lack of DNS server diversity? If "doesn't resolve" means "the target domain itself exists but none of the authoritative name servers for the domain respond", those mail systems doing as mentioned above should most probably be replaced, because they do not properly and reasonably distinguish between "hard" and "soft" errors when using the DNS.
Yup, but don't tell me! :-) Unfortunately "it works most of the time", or "it always works for us" keeps such broken stuff in production. -- Greg A. Woods +1 416 218-0098 VE3TCP <gwoods () acm org> <robohack!woods> Planix, Inc. <woods () planix com>; Secrets of the Weird <woods () weird com>
