I do not have Gmail but I have 3 Yahoo AT&T email accounts. When set up the email accounts work fine and I am able to send and receive email from my EVO for a few days (so everything is set up correctly and there is no problem with the phone). The after a few days I can always receive but when trying to send mail I get the message list above. The only way I can stop the message and send email is to delete the email account and set it up again. Again it must be set up correctly because it sends email for a few days. Any thoughts? Thanks in advance.
