UTM9 Email Protection SMTP Exim-out

I am using UTM 9.708-6 with Exchange Server 2019.

Everything was running fine, until 2 days ago. I made a change into the Exchange receive connector Relay configuration. Due to an additional server, I had to extend this value. Before it was 10.0.0.1-0.0.0.6 and I changed it to 10.0.0.1-10.0.0.9. The problem with this new value, was maybe, that Sophos (10.0.0.7) was included into this range. Up this time exchange did not receive/send any email.

So I changed it again to: 10.0.0.6 and 10.0.0.9-10.0.0.10, but still I can't receive any emails. I restarted Exchange and switched the Email protection on and off.

In the image of the SMTP-Protocoll it looks like, that Exim is sending the emails to the Exchange-Server(10.0.0.5).

But in the Live-Protocol I always see the start and end queue massages:

It seems to me, that there is some problem betwenn Exim and Exchange!

What can I do to solve the problem?
