SMTP - Simple Message Transfer Protocol
Firebind is a Network Path Scanner that will allow you to test any TCP or UDP port or range of ports to confirm whether those ports are open and are not being blocked by a firewall in the egress or OUTBOUND (client machine to Internet) direction.
Please note: The primary port testing feature of Firebind requires the Java plug-in. If you're a first time user, you will need to accept the certificate when prompted. If you don't have Java, please visit www.java.com to install it. You can try the Firebind Java tester by clicking here.
If you would like to test ports other than the SMTP - Simple Message Transfer Protocol ports or perform tests without a delay, please subscribe to one of our testing products which allows you to select any custom range of TCP or UDP ports from 1 to 65535 with no delay.
This page is configured specifically to test the SMTP - Simple Message Transfer Protocol network ports with a delay between ports (greater than 1 second).
SMTP - Simple Message Transfer Protocol uses the following ports:
- TCP: 25
This test will be performed at a standard rate of up to 30 ports per minute.. To perform tests at faster speeds sign-up for a Firebind Connect account here.Start Test...
