I've some problem with DNS
If you take a look at http://www.dnsstuff.com/tools/dnsrep...ionsvenice.com
My ns2 is down at the moment (raid array in maintenance).
So I've got some problem only with mail DNS...
WARNING: One or more of your mailservers is claiming to be a host other than what it really is (the SMTP greeting should be a 3-digit code, followed by a space or a dash, then the host name). If your mailserver sends out E-mail using this domain in its EHLO or HELO, your E-mail might get blocked by anti-spam software. This is also a technical violation of RFC821 4.3 (and RFC2821 4.3.1). Note that the hostname given in the SMTP greeting should have an A record pointing back to the same server. Note that this one test may use a cached DNS record.
netsolutionsvenice.com claims to be non-existent host www.netsolutionsvenice.com:
220 www.netsolutionsvenice.com ESMTP Postfix (Ubuntu)
What do I have to do to solve this small problem?
