what kind of email account do you have? Also you need to make sure that your phone is properly connected to the internet for it to work. So either 3/4g or Wifi will need to be enabled and connected.

Check where you went wrong. Caps, or any other little mistake, can cause the computer (on the server side) to reject you.
Also try to find out if the provider has a server error.

One problem is that the incoming (POP) mail server shown in the error message appears to be incorrect. The server address should be "pop.att.yahoo.com" (with a period between "att" and "yahoo"). The incorrect mail server address may interfere with authentication of the sender's email address, which is needed before the outgoing message is sent.

The "530 authentication" message indicates your outgoing (SMTP) server likely requires "server authentication". Also, the "Port 25" message indicates your email program is currently trying to send via Port 25, with no SSL; but Ameritech/Yahoo accounts appears to use Port 465 with SSL enabled.

I would suggest you check the settings for your Ameritech email account in your email program. You may need to correct several settings. The steps to access account settings are somewhat different for various email programs (Outlook, Windows Live Mail, Thunderbird, etc.). You should be able to find guidance in the "help" section of your email program.

This may be due to the means of authentication being used -- by the STMP server you are sending to and/or the authentication options selected in your Entourage setup. Mail servers commonly establish restrictions based on authentication to restrict who can send mail through them as a means of preventing spam.

Cable companies for example, and possibly your campus network, often restrict the sending of Mail to those computers that have a local connection to their network based on the IP address they are using -- i.e. where you plugged in or which wireless adapter you are connected to. Alternatively, many others require your mail client to present your user name and password to authenticate... or possibly to authenticate only in those cases when you are not connected locally.

So... to get an iron clad answer, you need to find out from the Mail server administrators what type of authentication is required. This information is often listed on "help" web pages describing how to set up your mail client... or call them if you can. Alternatively, check your Entourage setup to see how it is contacting the server for outgoing mail. Try changing the authentication method to use Password authentication if it is not already. Ultimately, the mail administrator for your Mail server is likely your best help resource.

Hope this helps.
