When i click "Tell" on the iPhone, i get an error "your phone can not send emails".

To Change Your iPhone, iPad or iPod Touch SMTP Port Settings

1. Go to Settings.
2. On the Settings screen, tap Mail, Contacts, Calendars.
3. Tap the email account you want to change.
4. Tap SMTP and the SMTP server you want to modify.
5. If you have Use SSL turned on, use port 465. Otherwise turn Use SSL off, and try these other ports for SMTP: 80, 3535, or 25.
6. Go to Mail, and check to see if you can send email. If not, repeat steps 1-5 and try a different port.
