Thank you for bringing that up. I just went through the hassles to
contact Barracuda.

This particular server and IP haven't had any SPAM related troubles in a
long time. So it's the same old story: If you run a list server (even if
it's just opt-in) it eventually gives that IP a bad reputation. /shrug
