    You can also try to re-create SMTP monitor. Set Interval to 30, and Timeout to 91. And enable debug (Advanced configuration for the monitor), it may show some info in logs...

I am using the latest version for BigIP LTM which is 11.6.0 Build 1.0.403. This is the first SMTP health check and VIP that I'm setting up on the appliance. SNAT is set for Automap and the SMTP monitor has been set at 5/16 and 30/91 for interval times with no difference. I even set up a TCP monitor checking ort 25 and it checks good. As Dmitri suggested before, I enable the Debug logs for the SMTP monitor and the logs show that the server is responding to the SMTP commands. Very odd. Everything shows proper connectivity and communication but the health check simply won't pass when its set to SMTP. it may be a flaw in the version I'm using. I'm going to step back a version and try again.
