    Hi support team.

    We’re using WP Mail SMTP on our websites without any issues until now; unfortunately all our websites are effected by the following error:

    Mailer: Andere SMTP-server
    SMTP Error: Could not authenticate.SMTP server error: QUIT command failed

    We have an integration and are doing a connection to Mailgun through SMTP. It occured on websites that we’re previously working without any issues, so it’s not an issues with credentials.
