    I dowload the eicar from here: https://support.kaspersky.com/viruses/general/459 and the firewall do not stop it.But the win defender do.

    Hello magnewi,
    I tested it locally with Firmware:425AALA1ITS-WK51-r81231 and usg can block it.(Mail from PCHome account)
    Please make sure you enable the Anti-virus profile, and Enable Virus Outbreak Detection for this scenario.

    But it's HTTPs will USG40 intercept the encrypted traffic ?

    I'm also interested in configuring the USG in A/V scanning in case all mail traffic is being sent over https / ssl.
    Any SSL chain interruption between source and final recipient should normally be considered as security threat. Insofar and since all german ISPs have switched their e-mail traffic to SSL only, we have disabled any SSL inspection for SSL secured traffic.

    Hi together,
    my last information from ZYXEL was, that encrypted mail traffic is not scanned. They will be implement in a future release the posibility to scan encrypted mail traffic like the uncrypted traffic.

    Perhapse @Zyxel_Charlie can post the actualy status about the implementation ? :)

    regards

    Hello all,
    If you want to block the eicar (https download, encrypted traffic ), the device need to be enabled SSL Inspection(The USG40 does not support it).
    Moreover, just like Christian mentioned,  the USG series does not scan the encrypted mail traffic like Gmail.

    Hello ChristianG,
    We still evaluate this enhancement. 
    Therefore, the request "the encrypted mail traffic will be scanned by device" I would like to move this request to ideas section. Once your ideas get lots of Likes on ideas section, we will give it to our product developers to have them evaluated and tell you the feedback!

    Hello @Zyxel_Charlie
    if the functionality "mail scan" with encrypted mail traffic is not in scope.... perhapse ZYXEL can plan to offer a UTM License bundle without the AntiSpam module ;)
