Intelligence Brief

Operational FAQ

What makes port 25 special for SMTP operations?
Port 25 is the original SMTP port, often configured with minimal security on older servers. Unlike ports 465/587 which enforce authentication, port 25 servers frequently operate as open relays, allowing unrestricted email sending without credentials. This makes them extremely valuable for high-volume operations.
How do I verify my network supports port 25?
The tool includes a comprehensive network compatibility tester that verifies port 25 connectivity. Most residential ISPs block port 25, so you'll need a business connection, VPS, or dedicated server. The tester will confirm your setup and suggest alternatives if port 25 is blocked.
What are the spoofing capabilities?
Full email spoofing allows you to send from any address without authentication. You can manipulate all headers including From, Reply-To, Return-Path, and custom headers. Configure custom EHLO/HELO domains for server greetings and bypass SPF/DKIM checks on misconfigured servers.
How many emails can I send through one SMTP?
Open relay servers on port 25 have no artificial limits. You can send thousands or millions of emails through a single server, limited only by server capacity and bandwidth. This is why each discovered SMTP is extremely valuable - one server can handle entire campaigns.
What are the private methods included?
Our proprietary techniques include advanced SMTP handshake sequences, response code exploitation, authentication bypass algorithms, and methods to identify misconfigured servers. These exclusive methods aren't publicly documented and provide significant advantages over public tools.
Can I scan IP ranges to find servers?
Yes, the tool includes a powerful multi-threaded IP scanner. Specify ranges (192.168.1.1-255) or CIDR blocks (/24, /16), and it systematically discovers open port 25 servers. The scanner identifies open relays, tests authentication, and validates sending capabilities automatically.
