<P>Confirmed that mx ip and not hostname that has A-records.</P> <P>You can easily use: <A href="http://www.dnsstuff.com/tools/dnsreport.ch?domain=go-active.co.il" mce_href="http://www.dnsstuff.com/tools/dnsreport.ch?domain=go-active.co.il">http://www.dnsstuff.com/tools/dnsreport.ch?domain=go-active.co.il</A> to check on any domain you have problems with. Their report is mostly accurate and very informative. DNS report in this case says: "<STRONG>MX is host name, not IP"</STRONG> which is somewhat misleading.</P>

<p>An email problem has shown up recently sending to addresses at go-active.co.il.  If I do an NSLOOKUP on this domain I get</p><p>C:\>nslookup Default Server:  mmy Address:  192.168.101.1 > set type=mx > go-active.co.il Server:  mmy Address:  192.168.101.1 Non-authoritative answer: go-active.co.il MX preference = 5, mail exchanger = 192.114.186.50 go-active.co.il MX preference = 5, mail exchanger = 192.114.186.51 go-active.co.il nameserver = ns.secured.co.il go-active.co.il nameserver = ns1.secured.co.il ns.secured.co.il        internet address = 192.115.31.16 ns1.secured.co.il       internet address = 212.25.68.218</p><p>If I do the same with the CNAME option set I get</p><p> C:\>nslookup Default Server:  mmy Address:  192.168.101.1 > set type=cname > go-active.co.il Server:  mmy Address:  192.168.101.1 go-active.co.il         primary name server = ns.secured.co.il         responsible mail addr = demo.shopy.biz         serial  = 2006121825         refresh = 10800 (3 hours)         retry   = 3600 (1 hour)         expire  = 604800 (7 days)         default TTL = 86400 (1 day) </p><p>When mercury 451 is trying to send email to this domain I see in the MercuryE window</p><p>Resolved CN for 'go-active.co.il' to 192.114.144.116 Connecting to 192.114.144.116 Connection error.</p><p>There is no SMTP server at 192.114.144.116.  Looks to me like this domain's DNS records are a little screwed up.</p><p>Can someone confirm this?</p><p>Thank You  </p>

<p>An MX record must not contain an IP number, so there is no correct mail handler to be found for this domain. If there is no legitimate MX the address registered for the domain itself should be used, and an NSLookUp for go-active.co.il returns 192.114.144.116. In this case there is of course no mail server present there.</p><p>/Rolf </p>
