Re: Dovecot with Postfix "no SASL authentication mechanisms"

so you have to check, when it is put on on and same error it means the sasl service could not be started, check if the service is UP on your server, then in log if there is any error about this topic,

then if i am not wrong when you put yes it means now you need smtp authentication to connect on server on client mail conf, i dont know exactly your conf

why you need sasl ? do you really need it ? if yes it has to be configured every where no ?

me@example.com in smtpd authentication have to use authentication (with username and password) than you have to configure in dovecot how to get user_query and password_query

try to look a full tuto and define if you need sasl or not ?
