Testing AntiVir MailGate after Installation
After installing AntiVir MailGate, it is recommended that you test its functionality.
To do this, you can use a test virus, called Eicar, which is recognized by all virus
scanners. This will not cause any damage, but it will force the program to react
when an email scan is performed, if the installation (and configuration) is correct.
