    Hi All,
    I've setup a new server but I get this warning…

    An idea how to prevent this ?
    Thanks !

    Check Your dovecot configuration.
    Which version of dovecot You have?

    In Your configuration check this directives:
    Code:
    disable_plaintext_auth = no
    auth_mechanisms = plain login

    Hi,
    Thanks for your answer…

    The version of dovecot is : 2.1.7

    Here is what I've in Dovecot.conf :
    Code:
    listen = *,[::]
    protocols = imap pop3
    auth_mechanisms = plain login
    disable_plaintext_auth = no
    log_timestamp = "%Y-%m-%d %H:%M:%S "
    mail_privileged_group = vmail
    ssl = required
