Block inbound ASN# but allow outbound for email

Hello.

I hope everyone is safe and healthy.

Using CSF on Centos server.

Love it. Here is a conundrum.

This ASN is microsoft: ASN8075

When I insert that into the csf to block, it blocks it no problem but also doesn't allow me to send emails to subsribers in that range - keep getting DNS request timeout.

So is there a way to block an ASN inbound from the scanners and such, but allow outbound email as an exception?

Thank you?
