Not getting e-mails after password change

[James Mbabazi]

Hi Atlassian team, we changed our e-mail password and we updated the handler with the new password. 

When we test e-mail sending, its not working. We get the error below. 

javax.mail.AuthenticationFailedException: [AUTHENTICATIONFAILED] Invalid credentials (Failure) while connecting to host 'imap.gmail.com' as user 'XXX' via protocol 'imaps

The user and password are setup correctly and before we changed the password the handler was working without any problems.

I can't figure out what I'm missing.
