Worked fine for me. I emailed a cycorder video and it worked flawlessly. I also have yahoo email and under address I have: smtp.yahoo.com, not 'mail'. Try that.. good luck.
Tried it still no luck, still get (error faild to send the mail! please try again). the reason i had smtp.mail.yahoo is because when i looked settings for yahoo they all said the same thing.
I got it to work but it seems you have to manually enter each e-mail address...I think that makes it somewhat of a pain. Other than that it is a great app.
Tried twice with gmail, iPhone freezes and then reboots. Uninstalled this 'til it gets to version 2 something, No way to choose an email address from your contacts?! WTF? Like I have all these addresses in my mind. Nice idea, neat GUI, but overall this fails.
Very useful app. Still needs improvement though. First time I tried it my phone crashed and did a reboot. The second time, still waiting for the file to send also.
