You may get this error while enabling the smtp_auth using cyrus with postfix

[root@work1 postfix-2.9.1]# postfix start
postfix/postfix-script: starting the Postfix mail system
[root@work1 postfix-2.9.1]# telnet localhost 25
Trying 127.0.0.1...

Feb 23 15:57:23 work1 postfix/master[10992]: warning: /usr/libexec/postfix/smtpd: bad command startup -- throttling

Reason and solution:
The Postfix-with-Cyrus-SASL build procedure has changed. You now need to specify -DUSE_CYRUS_SASL in addition to -DUSE_SASL_AUTH

Run the command as follows:
[root@work1 postfix-2.9.1]# make makefiles CCARGS="-DUSE_SASL_AUTH -DUSE_CYRUS_SASL -I/usr/include/sasl" AUXLIBS="-L/usr/lib -lsasl2"

Now it works
[root@work1 postfix-2.9.1]# postfix start

[root@work1 postfix-2.9.1]# telnet localhost 25
