Sorry for inconvenient in my explanation. In my first email I told that
this problem happened after restart the firewall and mail server before
that I did not have this problem and it means Secure Authentication
mechanisms worked.
I don't know Which non-plaintext or plaintext SASL mechanisms my server
support.
how can I find out?
Instructions for testing your server, which includes
displaying mechanisms offered, can be found here:
http://www.postfix.org/SASL_README.html#server_test
Note: if you configured your server to offer different
mechanisms to an encrypted connection, test with openssl
rather than telnet:
% openssl s_client -connect server.example.com:25 -starttls smtp
