Relay Test

This script will test whether a message to the address entered in the form is accepted by the server entered. It attempts to convince the server to accept the message using a number of different exploits. If 'Invasive test' is checked a message will actually be sent to the server if it accepts it. In some circumstances a server may accept a message and reject it after further processing.

You may also enter the name of a host for which the server being tested does relay mail to test a number of exploits that use this. If you leave the Relayed host field blank the name of the server will be used instead.

You may only test the machine from which you are viewing this page.

¹ Here you can specify the name of another host that the server you are testing accepts mail for. This is used in some tests, if you leave it blank the server name will be used.

² Check here to have a message actually sent through the server. This is useful for checking if messages are accepted initially but rejected later after processing.
