I am using Yahoo Push which works under Btinternet. Apart from the fact that sometimes the 'push' doesn't seem to work too well, and that fetch seems to be the way mail is delivered, I have noticed that emails which are pushed to my iPhone also seem to disappear. This seems to happen when I log on to my email account through entourage and download copies of my btinternet (yahoo) mail off of the server. My account is set up to remove the copies of the email from the server when it downloads it through the POP account. When the email is downloaded/removed from the server it also simultaneously removes the pushed email from my iPhone. How can I prevent pushed emails being removed from my iPhone without leaving loads of mail on my server ?
