[IMail Forum] DNSReports Mail server warnings

[Wolf Tombe]

I’m running iMail 8.12 with multiple mail domains each configured to have its own IP number and each with its own DNS and MX records accordingly.  I preparing to launch these domains soon and while doing DNS and Mail Server testing I find I’m getting the following two “warnings”.  Although neither of these appears critical, I’d prefer to have no warnings if possible.  With this in mind, I’m wondering what iMail settings I should change to resolve these issues.   WARNING: One or more of your mail servers may be 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). This probably won't cause any harm, but may be a technical violation of RFC821 4.3 (and RFC2821 4.3.1). mail.proudandout.net claims to be host *******************************2*22************************.     WARNING: One or more of your mail servers does not accept mail in the domain literal format ([EMAIL PROTECTED]). Mail servers are technically required RFC1123 5.2.17 to accept mail to domain literals for any of its IP addresses. Not accepting domain literals can make it more difficult to test your mail server, and can prevent you from receiving E-mail from people reporting problems with your mail server. However, it is unlikely that any problems will occur if the domain literals are not accepted.   mail.proudandout.net's [EMAIL PROTECTED] response:    >>> RCPT TO:<[EMAIL PROTECTED]>    <<< 550 not local host [67.101.20.141], not a gateway   Any suggestions will be greatly appreciated.   Thanks!
