From what I read the F5 uses Linux SSMTP email client to generate emails and it is very limited. You can check for Linix SSMTP options to specify TLS1.2 but I couldn't find them for 20 minutes so you may need to look for hours if it is possible https://support.f5.com/csp/article/K13180 .

 

 

 

Better configure your syslog or SIEM server that the F5 sends the logs to do the email generation.

    So I'm trying to use APM to generate an email that provides a OTP to a user based on their email address found via AD Query. I may just have to pose the question to support to see if there is a db variable that controls that.

     

    SSMTP (i.e. mailhub) seems to act differently than the GUI version which is odd.
