warning: unsupported SASL server implementation: cyrus

Sponsored Links

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...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.

Errors:

Feb 23 15:54:17 work1 postfix/master[10992]: daemon started -- version 2.9.1, configuration /etc/postfix
Feb 23 15:57:22 work1 postfix/smtpd[10996]: warning: unsupported SASL server implementation: cyrus
Feb 23 15:57:22 work1 postfix/smtpd[10996]: fatal: SASL per-process initialization failed
Feb 23 15:57:23 work1 postfix/master[10992]: warning: process /usr/libexec/postfix/smtpd pid 10996 exit status 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
postfix/postfix-script: starting the Postfix mail system
[root@work1 postfix-2.9.1]# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
