Blacklist for Gmail!

Hi I'm getting this message from my Mac when sending mail. Sends fine from my iphone on the same wifi home network.
It's a Gmail server IP and it's also not listed on manitu site as blacklisted.

According to manitu, that IP is not listed: http://www.dnsbl.manitu.net/lookup.php?language=en&value=209.85.218.47

That's what I said but the problem persists. It's also a Google Mail IP so it shouldn't be blacklisted

Apologies, missed that part. Do you have any custom DNS set on your Mac?

Nope. Stock standard stuff. I've noticed it's just this single recipient so the problem could be on their side
