Check your mail server performance with Email Security Grader

Email Security Grader (www.EmailSecurityGrader.com) is a newly launched online tool that provides useful information for IT administrators and Mail System managers interested in evaluating the level of security in their mail infrastructure.

Extensive and relevant Email Security Tests

Built around a very simple interface, ESG simply asks for the domain name you want to test. It will then conduct a series of tests and analysis:

* MX records check
* Reverse DNS test
* DNSBL (Spam Blacklist) check
* SPF record verification (server- and client-side)
* Open Relay test and Email format validation
* SMTP, POP3 and IMAP clear text authentication

Once the test is complete, ESG will present the user with a full Email Security Report, including a score (in percent), a rating (from very poor to very good security) as well as an extensive set of information ranging from what each test does to why it is important to solve the issue.
