Are you seeing an error or other message? If you go online to the Gmail website can you login and send mail from there? Not giving us much information to go on.

Which email app are you using? If you have multiple email accounts set up on it are the other email accounts also having a problem with outbound email? Also, is the problem just sending from your Gmail or also receiving? How long has this been an issue?
