Hi,

 

Anyone found a workaround for the issue that www.dnsstuff.com
<http://www.dnsstuff.com's/> 's mail testing section attempts?

 

"Mail server host name in greeting"

 

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
<http://www.DNSstuff.com/pages/rfc821.htm>  4.3 (and RFC2821
<http://www.dnsreport.com/tools/rfc.ch?detail=2821>  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.

spamfilter.kencook.com claims to be invalid hostname
'***************************************2*****200******2**0': 
   220 ***************************************2*****200******2**0 *0*00

 

Thanks,
