no SASL authentication mechanisms

[Outlaw]

I have postfix + dovecot
I can login on mailbox but i don't send anything.
In logs, i have:

Code:

Mar 26 23:58:52 localhost postfix/smtpd[2217]: warning: SASL: Connect to smtpd failed: No such file or directory
Mar 26 23:58:52 localhost postfix/smtpd[2217]: fatal: no SASL authentication mechanisms
Mar 26 23:58:53 localhost postfix/master[2214]: warning: process /usr/libexec/postfix/smtpd pid 2217 exit status 1
Mar 26 23:58:53 localhost postfix/master[2214]: warning: /usr/libexec/postfix/smtpd: bad command startup -- throttling

saslauth is running and:
saslauthd -v
saslauthd 2.1.22
authentication mechanisms: getpwent rimap shadow

What is wrong?
