Hi, Gmail has recently adopted the new security standard OAuth 2.0 and this means that now mailwatch-plugin can't connect to your Gmail account (error 401). The solutions are reported in this discussion http://stackoverflow.com/questions/25413301/gmail-login-failure-using-python-and-imaplib, that is: 1) you choose to allow the access for less secure apps https://www.google.com/settings/security/lesssecureapps; 2) mailwatch-plugin implements the OAuth 2.0 protocol (better solution)
