External relay with Sophos XG as MTA

Hi all,

After running XG for a while, I have setup relaying (Mailserver is Office 365), I only use the XG email part for relaying mail from internal devices to the ouside, ex. NAS, Camera, IOT a.s.o.

All works great.

Now I have this one device, on the WAN at another location sending mails. I have added the device in the relay window, and created a host record.

I can see in the firewall that traffic is blocked, when it arrives at rule "0", gthe default block.

 

But I have the default rule i XG where SMTP and SMTPS is allowed on any interface, should that not solve it, or do I need to create a business rule og firewall rule also?

Please remember, there is no mailserver on the LAN!

So a NAT rule fra port 587 to XG WAN IP??
