I am struggling with the error above for more than 5 hours.
I had tried to remove Postfix completely and I had followed the instructions of the next manual and the SASL manual in order to reinstall it.
When I am trying to login with telnet, the server blocks the login and I am getting this:(with smtpd -v for more verbose):
postfix/smtpd[26301]: xsasl_cyrus_server_create: SASL service=smtp, realm=(null) postfix/smtpd[26301]: name_mask: noanonymous postfix/smtpd[26301]: warning: xsasl_cyrus_server_get_mechanism_list: no applicable SASL mechanisms postfix/smtpd[26301]: fatal: no SASL authentication mechanisms

Hopes this data will help you to help me..

You can have saslauthd installed but not have any mechanisms installed. It's quite frustrating and poor error-proofing, IMO.
"no applicable SASL mechanisms" literally means it can't find any of its mechanisms. On a Fedora-based system you'd need to install the cyrus-sasl-plain package if you want to use the 'PLAIN' auth mechanisms (i.e. SMTP/STARTTLS).
