Relay Test Pro is a tool for network administrators, that allows to test a specified mail server for open relays. It runs series of tests designed to detect open relays and create a detailed report of the findings.

Relay Test Pro is not designed to find vulnerable mail servers - it only scans one server at a time.

Key features:
