Counting SMTP emails in Forwarding VS

can we somehow bind TCP Profile to a Forwarding (IP) VS?

 

 

You can't add a TCP profile to a forwarding virtual server.

 

 

Or, can we look inside the IP PAYLOAD for SMTP commands or TCP session without having TCP Profile bound with VS?

 

 

No, in order to inspect the TCP payload from an iRule you need to add a TCP profile added to the virtual server.

 

 

Which functions can I use in my IRule?

 

 

I think you'd need to use a standard TCP virtual server and then call TCP::collect/TCP::release to inspect the payloads to count the number of emails. I'm not sure how scalable this will be for a high capacity virtual server. But SMTP doesn't necessarily need to be real time, so a bit of latency might not be a problem.
