Welcome to Android Central!

Which phone are you using, which email provider, and which email application?

It sounds like you need to update your outgoing mail server settings, but I can't tell you where to find them, or where to update them in the email application, without knowing the answers to the questions above.

If you need additional help or have more questions or details to share, please join the site so you can reply in this thread. See this link for instructions on how to join Android Central.

The easiest way, since we have no other information, is to delete the email account (in the email app, not in Accounts), then add it back as an existing account.
