i have yahoo mail configured on my iphone (using the iphone's automatic settings for yahoo) and everything has been working fine for awhile. now it seems the phone is not sending emails. it makes the "WHOOSH!" sound and everything but when i look in the SENT folder the messages do not appear. Additionally, the recipients do not receive a message.
My Yahoo email seems to be working now (KNOCK-ON-WOOD!!!). I can send email via the iphone, then check online and the email I send is in the Sent Folder (it's in the sent folder on my iphone, too). When I send an email from my computer, it shows up in my sent folder on my iphone. It's "pushing" too. (again KNOCK-ON-WOOD)
I don't know if the problem with my Yahoo email was somthing with Yahoo or the iphone. I returned the iphone for a new one last friday and ever since then, my yahoo email has been working. Coincidence??
