Help! I came from a Blackberry, and my entire company users Blackberry's. We use Outlook exchange. When I first got my Iphone, I set up my email account using att.yahoo as my smtp (I have ATT. Yahoo DSL at home). However, it was sometimes taking several hours to send an email. For some reason, I am unable to use my company server as a smtp. Then I started using gmail as my smtp, and I developed 2 new problems. 1) Even though I was sending an email from the inbox of my company email account on the iphone, the recipient saw it as from gmail, and so when they replied, the reply went to my gmail and not my work account. 2)I used to be able to delete emails on the iphone, and they would get deleted from the server, and also drop emails in folders on the iphone, and they would get moved to the folder on the server, but now I can't do that anymore. I know it can be done, because I used to do it, but no one at apple can figure out how to get me back to that. Can anyone help?
