    Hello :)

    Judging from the bounce message you posted, the problem is that RDNS is not setup for How long after setting up the RDNS record did you try sending that message? For instance, on my end I do see the RDNS record setup for

    [~]# host domain name pointer

    However, I used a few websites that check RDNS and a couple of them showed that RDNS for was not setup as of yet. It's possible this will take a day or two before it's propagated.

    Thank you.
