  Subject: [coba-e:05140] DNS Report Warning


  On my BQ machine, I have it set up with the main site UHOSTME.NET =
using the primary IP address 216.130.248.50.  I have another site =
UHOSTME.COM set up using IP address 216.130.248.51.  When I check =
UHOSTME.COM at DNSREPORT.COM, I get a warning that the mailserver at =
216.130.248.51 is not UHOSTME.COM, but is UHOSTME.NET, the main website. =
 Apparently, it appears to me that the BQ machine assigns the main site =
name (and server's name) to all of the IP addresses on the server.  =
According to DNSREPORT.COM, this is a technical violation of RFC821.  Is =
this a cause for concern?

  "Mail server host name in greeting

  =20

  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.

  www.uhostme.com claims to be host www.uhostme.net [but that host is at =
216.130.248.50 (may be cached), not 216.130.248.51]."
