I am not receiving my bellsouth.net emails on my Mac, and have not been receiving them for more than a week. I am however; receiving them on my iphone and ipad. I am unable to figure out what I need to do to correct this. Please provide help by providing me with step-by-step instructions to correct this. When providing these instructions, please keep in mind that I do not know a lot about computers. I would like to thank you in advance for your attention to this matter. Thanks!
