I had a bounce:

I'm using 94.198.96.72/29 since April, and I'm trying to remove IP
blocks as I find them.
That's not clearly an IP-based block. It looks like that is a
consequence of tana.it having -all in its SPF record. That is explicitly
a prohibition on forwarding, whether the SPF specs say so or not. It is
certainly comprehensible that a mail system which does a lot of
forwarding does not want to handle your unforwardable mail.
Since they block my server,
Not your server, your sender domain.
I wrote them from Gmail. Surprise:

How was that joke about TBTB?
Again, this does not look like a rejection due to the SMTP client
machine's network circumstances. IOW: I don't think it's a case of MS
blocking Google or any Google network per se.
But that's just a hunch...
