Hi, first off, very sorry, am new to this, please take pity on a stranger!
I have successfully installed a server I our company and set up exchange server 2010.
However, mail from AOL email addresses doesn't reach us, and we can't send to AOL addresses either.
I am told that I need to set up a reverse DNS on the ip address, I don't understand what this means.
Please could someone tell me in idiot speak, how to do this? I'd be really grateful.
Thanks
