Will carry on with this thread and hoping someone can help with an e-mail problem where some are getting through and some are not.
The ones not getting through show this error:-
Code:
The reason for the problem:
4.1.2 - Bad destination host 'DNS Soft Error looking up tld.com (MX) while asking recursive_nameserver0.parent. Error was: unable to reach nameserver on any valid IP'
DNS check shows all ok:-
Code:
CheckDNS.NET is testing tld.com
CheckDNS.NET is asking root servers about authoritative NS for domain
Got DNS list for 'tld.com' from K.GTLD-SERVERS.NET
Found NS record: ns1.xxx.co.uk[xx.xx.xxx.xxx], was resolved to IP address by NS6.NIC.uk
Found NS record: ns2.xxx.co.uk[xx.xx.xxx.xxx], was resolved to IP address by NS6.NIC.uk
Domain has 2 DNS server(s)
CheckDNS.NET is verifying if NS are alive
DNS server ns1.xxx.co.uk[xx.xx.xxx.xxx] is alive and authoritative for domain tld.com
DNS server ns2.xxx.co.uk[xx.xx.xxx.xxx] is alive and authoritative for domain tld.com
2 server(s) are alive
CheckDNS.NET checks if all NS have the same version
All 2 your servers have the same zone version 2009051802
CheckDNS.NET verifies www servers
Checking HTTP server www.tld.com [xx.xx.xxx.xxx]
HTTP server www.tld.com[xx.xx.xxx.xxx] answers on port 80

CheckDNS.NET tests mail-servers
Domain tld.com has only one mail-server
Checking mail server (PRI=10) mail.tld.com [xx.xx.xxx.xxx]
Mail server mail.tld.com[xx.xx.xxx.xxx] answers on port 25
<<< 220 server2.xxx.co.uk ESMTP Postfix
>>> HELO www.checkdns.net
<<< 250 server2.xxx.co.uk
>>> MAIL FROM: <dnscheck@uniplace.com>
<<< 250 2.1.0 Ok
>>> RCPT TO: <postmaster@tld.com>
<<< 250 2.1.5 Ok
>>> QUIT
Mail server mail.tld.com [xx.xx.xxx.xxx] accepts mail for tld.com
All MX are configured properly
Not on any blacklist and didn't have this trouble using ubuntu/ispc2
Any ideas?
Thanks in advance.
