I tested authentication with telnet and openssl and I received this
error " 535 5.7.0 Error: authentication failed: authentication failure"
what should I do?


Start here:

and here:
http://www.postfix.org/SASL_README.html

The first thing is to check your postfix logs for errors and warnings. Often these will tell you exactly what the problem is. http://www.postfix.org/DEBUG_README.html#logging


If this problem started after a reboot, an obvious thing is to make sure all the services related to your sasl started.


If you need further help from the list, please see:
