Hi Leonardo, thank you for your answer in this post.

 

Can you share how to config SMTP Relay with Office 365 platform?

 

Thank you so much.

I did not find any deployment guide for that. As SMTP is a standard, I would say that the configuration should be the same as for any other SMTP server.

 

The only thing I found is to add F5 in the middle, to add SSL layer:

 

https://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/bigip-ssl-administration-12-0-0/16.html

 

Anyway, you need first to decide why you want to have F5 doing the SNMP relay. Basically, what functionality you are adding with F5, like SSL, load balancing, etc...

 

Some things may already exist. For example, I would assume Microsoft already provides SMTPS. Their SMTP servers are load balanced for sure. So, in those cases, there is zero value to add F5 there.

 

F5 has SMTP and SMTPS profiles, SMTP monitors. It can definitely handle SMTP traffic, you just need to understand what you want it to do.

 

Let me know if you have more questions or problems during the implementation.
