  Background:
    Given there exists an account with username "[user:user]" and password "password"
    Then it succeeds
    When bridge starts
    And the user logs in with username "[user:user]" and password "password"
    And user "[user:user]" finishes syncing
    And user "[user:user]" connects and authenticates IMAP client "1"
    Then it succeeds
