Outbound SMTP Relay
Hi there,
We are attempting to replace or IronPort email gateways by utilising our F5's.
Inbound, we have used the SMTP iApp, and secured this with client authentication, and this works fine.
However, for outbound, it doesn't seem to work. I have configured a virtual server, load balanced to our external 3rd party email servers for further routing. When I set the VS to have no client/server SSL profile, then the mail sends fine. However, when I add a server SSL profile, the F5 stops the connection straight away from our Exchange servers.
Has anyone else been able to achieve outbound, whereby the traffic from Exchange to F5 is unencrypted, and then the F5 encrypts from the VS to the nodes? Regards
Adam
