Greetings,
I wonder if the mailhub discussed in this this article may be the issue:
https://support.f5.com/csp/article/K15288
Perhaps review these sections:
Configuring the BIG-IP system to use a DNS lookup server
Configuring the BIG-IP system to use an SMTP server (11.5.0 and later)
Also, could be a bug if you are running 13.0.0 or later:

Let us know if this works for you and thank you! Kevin
