ESET Mailsecurity installed on exchange 2016 but pop3 grabber is on separate win10 PC

[esetuser22222 0]

Hello, 

we have one Exchnge 2016 and no direct MX receiving. 
Third Party POP3 Grabber called "POPCON" is installed on a separate Win10 PC in the local network.

It grabs the Mails via 995 from the provider and send it via Port 25 locally to the local ms-exchange-2016  (via exchange connector)

Question: Do you think ESET Mail Security will still secure the MS Exchange against SPAM and Virus Mail?

Thx/BR

I assume that with this setting both AV and antispam scan should be performed:

If not, please raise a support ticket.
