Not everybody knows that there exist a teststring which can be used to test a Antivirus / Antispam Installation. To use them is quite simple, you need to put them into a body or build a attachment with it.

To test a antispam installation:

1.) create a new email

2.) copy the following text to the message body:
XJS*C4JDBQADN1.NSBN3*2IDNEN*GTUBE-STANDARD-ANTI-UBE-TEST-EMAIL*C.34X

Note: Ensure that you copy this with no extra spaces or line breaks.

3.) From an external email address, send the new email message to a mailbox address on the server where you have installed the antispam software. The software scans the message, recognizes it as a junk email message, and takes action (as specified in your configuration settings).

NOTE: The GTUBE test overrides blacklists and whitelists. For more information on the
GTUBE test file, visit http://spamassassin.apache.org/.

To test a antivirus installation:

1.) create a new email

2.) Copy the following line into its own file, then save the file with the name EICAR.COM:
X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*
The file size will be 68 or 70 bytes.

3.) From an external email address, send the new email message to a mailbox address on the server where you have installed the antivirus software. The software scans the message, recognizes it as a junk email message, and takes action (as specified in your configuration settings).
