On two different gmail accounts, I have tried to send emails for the last week and they have failed under the claim the username and/or password were not accepted. I know this to be incorrect because username and password have not changed (as I determined via webmail logins). Reproducible: Always Steps to Reproduce: 1. Compose Email (gmail only email provider attempted) 2. Send email 3. Get error message. Actual Results: "Email sending failed: Failed to transport message. Authentication failed. Most likely the password is wrong. The server responded: 5.7.1 Username and Password not accepted. Learn more at http://support.google.com/mail/answer/14257" then what appears to be hashcode followed by - gsmtp. Expected Results: Email to be sent. I am using opensuse 12.2 with gnome and kde installed. I use gnome shell, but run kmail as it does, and has run well for quite some time.
Do you have error message in konsole ? or do you have error message in .xsession-error ? (when you try to send email)
