This is driving me crazy. Right now i have to use my yahoo bussiness email with gmail for it to get pushed to my iphone4. basically i forward my yahoo email to my gmail account then use the exchange settings on the iphone4 for it to push. only problem is when i reply to a email on the iphone it dont use the reply to address i have set in gmail. webclient works fine but iphone4 dont. so how do i get yahoo to work with push email and to be able to check email from the iphone and it show it read in the webclient? what are the settings? ive tired everything i could see online and it dont work at all.
