I have a yahoo.co.in account. I would like to emphasize the ".co.in" I use the mac mail and so far I was not able to send any emails. But recently, it stopped receiving emails too. I have OSX Lion. Can someone please run me through the steps of fixing this? I also don't want the yahoo server to delete my emails if i delete them on mac mail. How do I do this? I am not so smart to understand any technical terms. Please explain it to me in regular layman English. Thank you.
