XF 2.0 Error sending email

[VergilPrime]

Just noticed this in my logs today. Email was to myself and I didn't receive an email at the noted time. Other emails have gone through, and 235 doesn't appear to be a "failure" response. What do you think?

• Swift_TransportException: Email to (me) failed: Expected response code 250 but got code "235", with message "235 2.7.0 Authentication successful "
