    Ive been getting these warnings in Mail-Log for a whiel and they dont stop, it comes tons of them every day. And its always different ip adresses and hosts. example:

    adsl-dynamic-pool-xxx.hcm.fpt.vn
    Static-19.183.96.14.tataidc.co.in
    mdmarket2.com
    189-110-51-35.dsl.telesp.net.br

    Is there any way for me to stop this? I dont know whats wrong?

    Is the domain emailrambler.co.tv hosted on that server?

    Hi,

    No it's not, nor is any of the others that comes upp with that message.

    Thanks

    Ok, then these warnings are from the postfix dns name verification. Thats a useful feature to protect your server. So there is nothing wrong and I recommend to leave it as it is.
