I am trying to get emails through PHP ( 3rd party app) using following command, it is able to connect with IMAP with message "IMAP connection opened successfully but immediate after it is throwing this error.
SECURITY PROBLEM: insecure server advertised auth=plain
Here is a php command used.
_mbox = @imap_open( localhost:143/imap/notls/norsh, $username, $password)
checked dovecot config it is 'disable_plaintext_auth = no'
why dovecot is saying auth = plain, how can we resolve it?
Thanks in advance.
