In-Line SMTP with STARTTLS Offloading
We have a virtual server to load balance our SMTP/SMTPS traffic using SNAT Automap. It is currently performing TLS Offloading for STARTTLS but our SPAM Solution is not working properly since all the email appears to have originated from the F5.
Our solution is to move away from SNAT Automap, setup the Virtual Server in-line by changing the default gateway to the Floatter address of the F5 on our SMTP Servers and configure an IP Forwarding Virtual Server.
Would TLS Offloading still work when we place the server in-line or does TLS offloading require SNAT Automap to be used ?
