sendmail -- sender domain must resolve
Hey All,
I'm running sendmail 8.9.3 and pretty much left everything default. The
spam stoppers are in full effect..
I have a question about the following:
Mar 20 14:39:25 xxx sendmail[18726]: OAA18726: ruleset=check_mail,
arg1=
bebe.com Server: ns.server.com Address: ip.addy.here
*** ns.server.com can't find bebe.com: Non-existent host/domain
set type=mx bebe.com Server: ns.server.com Address: ipaddyhere
Non-authoritative answer: bebe.com preference = 0, mail exchanger = bebe-mail.bebe.com Authoritative answers can be found from: bebe.com nameserver = AUTH02.NS.UU.NET bebe.com nameserver = bebe-ns.bebe.com bebe.com nameserver = BEBE-NS2.bebe.com bebe-mail.bebe.com internet address = 208.240.224.197 AUTH02.NS.UU.NET internet address = 198.6.1.82 bebe-ns.bebe.com internet address = 208.240.224.225 BEBE-NS2.bebe.com internet address = 208.240.224.210 By looking at this.. I concluded that MX records aren't looked at when deciding if a domain resolves or not. So.. I do the some testing with hospitalforms.com (which doesnt resolve but has an MX record) and it worked.. So. Am I right when I assume that bebe.com's ns servers were most likely down for a period of time? Auth02.ns.uu.net is huge.. and 3 nameservers all go down at the same time? This doesnt seem right. Any suggestions?

Hi, first it could happen, second there could be some kind of DNS misconfiguration having caused this. mike

Why not the following commands ? set type=ANY server AUTH02.NS.UU.NET bebe.com Then you'll get all authorative info. Regards, Fred Mobach
