Free Tool Ferrets Out Mail Server Problems

Trouble receiving mail? Installing a new mail server? Need to make sure all your email servers are accessible?

Experienced network managers have long plodded through DNS queries, making sure that MX records matched A records which matched IP addresses. Then they checked SMTP ports to make sure the servers were open for business...

This can be a fairly time-consuming and error-prone process, especially if you or your email vendor, sport 11 mail servers, like IBM... Or two MX records that point to 15 hosts, like 3com.com... Or five MX records pointing to 18 IP addresses, some of which are only for outbound email, like sun.com. Free Tool Ferrets Out Mail Server Problems
