I don't know. How would I test this?
The only idea I have now is to ask them if they intercept, filter or rate

I'd advise to add IP 45.90.5.195 to client_checks instead.
I just added this.
great, your main problem should be solved.
Note that if you really have DNS issues, other problems may arise.
I recommend watching logs for mail from this mailing list ocasionally.
