Using STARTTLS in System | Configuration : Device : SMTP
Looking at the configuration options, it seems that STARTTLS is not supported, only implicit encryption is supported (generally on port 465). This is going to sound a bit goofy, but despite the notes in the "help" section I got a working configuration on our dev LTM. This very same configuration does not work in production.
Both devices are "BIG-IP 12.1.0 Build 0.0.1434 Final" dev is virtual, prod is physical.
Does anyone have any clues for me about what it going on here or any tricks I can use to get this to work? I'm trying to add the Office365 SMTP service which only supports STARTTLS. This is a screenshot of the working dev configuration which shouldn't work and doesn't work in production...
