pop3-login: Disconnected (tried to use disallowed plaintext auth)

Hi

I have problem with dovecot 2.2.10 - plaintext auth without SSL is not working. I'm upgrading old server and want that settings "stay same" as on old server. SSL has to be optional.

/var/log/maillog *pop3-login: Disconnected (tried to use disallowed plaintext auth): user=<>, rip=_._._._, lip=_._._._, session=<cxPkm4Ud5gBb7YZ/>*

my settings:

[root@mail dovecot]# grep ssl * -R -n

*conf.d/10-ssl.conf:8:ssl = yes*

*conf.d/10-ssl.conf:40:ssl_verify_client_cert = no*

*conf.d/10-auth.conf:90:auth_ssl_require_client_cert = no* *dovecot.conf:7:ssl = yes*

[root@mail dovecot]# grep plain * -R -n

*conf.d/10-auth.conf:11:disable_plaintext_auth = no* *conf.d/10-auth.conf:101:auth_mechanisms = plain login*

Thanx you for any help.
