- Hi Taen keren,
With SMTP services it is traditionally recommended to repurpose an old on premise Exchange (if in hybrid) or use a cloud server like Hyper V/Azure as it takes the load off of 365 and you have greater management (having access to IIS etc). These would then sit behind a smart host such as Mimecast to protect the domain (s) against blacklisting.
In security terms both are secure whether you go through 365 or spin up a VM with IIS. Just make sure if it’s the second option to lock down open relaying! Oh, forgot to add that the second option of the VM does have the benefit of permitting non-auth SMTP too whereas 365 does not - this is good for legacy devices and apps!
Had much fun with this in the past as you can tell! ;D
Hope that answers your question!
Best, Chris

ChrisHoardMVP - Thx - option 1 is the best then - as the 'legacy part' is not good 🙂
