The Sendmail IP Info application is an administrative tool for email system administrator’s on-the-go. It provides the functions necessary to help keep their corporate email infrastructure free from spam and other malicious malware. Administrators can easily check to see if a given host is listed on a DNSBL (blacklisting service) and also provide them with information on a domain’s SPF records—all from their iPhone.

- DNSBL query

Email system administrators can check whether an email server is listed on any public DNS Real Time Black Hole List. The application lets you send a query up to three DNSBL servers at a time and view the results of the query on your iPhone.

- SPF Check

SPF (Sender Policy Framework) is one of the most widely adopted Sender Authentication technologies. However, there are numerous email sites that publish incorrect SPF records which cause various problems for businesses trying to send/receive SPF signed messages. With the Sendmail IP Info app, system administrators can check whether the SPF records of their site are properly configured.

The free Sendmail IP Info tool is an essential tool for all email administrators.
