dovecot 2, hot to enable login and plain mechanism?

solved,

added

auth_mechanisms = plain login

in dovecot.conf and it works.

@sblantipodi:

As title.

My /etc/dovecot/dovecot.conf

doesn't contains the mechanism line, how can I enable the

mechanisms = plain login

???

Thanks.

Just add it?

Anyway, you probably either at least want TLS or want to use some non-plaintext authentication scheme.
