the client did not make any auth attempt
dovecot just logs what is happening

mostly when that happens the client is configured for a auth mech like
CRAM-MD5 and the server does not support it, so the client connects, get
from the server the list of supported auth-mechs and says "hm it don't
support what the user configured, bye"
