Thank you!

But as I understand, if OPNsense is configured as mail gateway, all clients will have to use it as mail server.
Please, tell me if I'm wrong

I just want OPNsense to scan attachments in SMTP packets without being mail server (see diagram)

Hello!

I want to scan files attached to the emails such as .pdf, .exe.
The only solution I've found is clamAV + postfix + rspamd (using OPNsense as mail server)
But I already have mail server in my network. So is there any possibility to do SMTP flow-based file scanning?

Thank you!
