controlling inbound and outbound flow

controlling inbound and outbound flow

Hi,

here's what I'm trying to do.  I have my own internal email security appliance (anti-spam, AV etc) which scans inbound and outbound email.  With Zoho, can I have control of MX record and also inbound and outbound email flow so emails are forwarded to my email security appliance to be scanned then back out ?  the same for outbound emails...is it possible with Zoho?
