F5 Device SMTP Server Config and TLS

Hi,

 

I'm trying to configure the SMTP server within Device -> Configuration -> SMTP but apparently it wants to communicate via TLSv1 which is an issue as the mail relay server that I have to use only allows TLSv1.2, obviously. Is there any variables that can be changed to make this connection want to use TLSv1.2 rather than TLSv1?

 

Thanks in advance on any guidance!

  • 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.
