Smoothwall and Office 365 EOP

[Hogwarts-Techie]

We have started to use EOP for our exchange server. We have setup all the mailflow and connectors to and from office 365. However, we have run into some issues with Smoothwall.

 

Smoothwall will not port forward, port 25 to the Exchange server unless the SMTP Relay is turn on. ( we have all the port forwarding setup on Smoothwall)

 

This is having a massive problem as Smoothwall still thinks it the SMTP relay sending out emails.

 

So we have two IP addresses sending out emails. (big no no in emailing terms)

 

Has anyone else got this setup? if so does it work?

I wish I could offer some assistance - I've seen to have hit blank stares whenever I mention Exchange server to Smoothwall. We have a hybrid setup and I've only ventured so far to get OWA and Outlook Anywhere running through it - I've left actual mail flow going through our TMG edge server. You would think Smoothwall would have a technical paper on how to integrate their UTM with Exchange Server, you know, one of the biggest email platforms in the world - I seriously think they have NFI.

 

I hope you manage to figure it out!
