New problem sending email.

WARN 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 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.
 
mail.educationalproducts.com claims to be invalid hostname '****************************************************************************************************************************': 
 
WARN Acceptance of abuse address WARNING: One or more of your mailservers does not accept mail to abuse@educationalproducts.com. Mailservers are expected by RFC2142 to accept mail to abuse.
 
mail.educationalproducts.com's abuse response:<br /> >>> RCPT TO:<abuse@educationalproducts.com><br /> <<< 550 5.1.1 User unknown 
 
WARN SPF record Your domain does not have an SPF record. This means that spammers can easily send out E-mail that looks like it came from your domain, which can make your domain look bad (if the recipient thinks you really sent it), and can cost you money (when people complain to you, rather than the spammer). You may want to add an SPF record ASAP, as 01 Oct 2004 was the target date for domains to have SPF records in place (Hotmail, for example, started checking SPF records on 01 Oct 2004).  
 
FAIL Domain A Lookup ERROR: I couldn't find any A records for educationalproducts.com. But I did find a referral to www.educationalproducts.com. (and maybe others). If you want a website at educationalproducts.com (as well as www.educationalproducts.com), you will need an A record for educationalproducts.com. If you do not want a website at educationalproducts.com, you can ignore this error.
