We’re both offering anecdotal evidence, but I have been working with mail servers of various kinds for the better part of 15 years and I have never seen an IP or mail server wind up on a blacklist for “no reason”
I would hesitate with WD. I’ve always been a fan of their drives but their software straight up wiped people’s backup disks a few years ago, iirc. That would give me pause before ever using their software again.
Been on that spare for a long time, if we don’t go without we may never replace the wheel anyway.
