The other day I rebooted my FreeBSD machine. Ever since then, messages to hotmail.com and yahoogroups.com are not going through - the mail logs report that there is a 'host name lookup failure' to the specific MX hosts (eg 'mx1.hotmail.com'). The thing is though, I can run dig/nslookup on these hotsnames perfectly fine - in fact I can even telnet to port 25 of all of these hostnames, issue a HELO, etc. Does anyone have an idea what might be going on here?
