[Dovecot] Stuck on an Error: " Connect to private/auth failed: Connection refused"

[Blake Carver]

Hi All,

I've recently recompiled Postifx & Dovecot and I'm hitting an error I
can't seem to chase down.

Running dovecot version 1.0.3 (dovecot -n is below)

Here's the error in my error log:
Sep 10 12:58:22 lishost postfix/smtpd[13726]:
xsasl_dovecot_server_create: SASL service=smtp, realm=example.com
Sep 10 12:58:22 lishost postfix/smtpd[13726]:

Sep 10 12:58:22 lishost postfix/smtpd[13726]: fatal: no SASL

Sep 10 12:58:23 lishost postfix/master[13721]: warning:
/usr/libexec/postfix/smtpd: bad command startup -- throttling

(In case it matters I recently makde postfix like so:)

make -f Makefile.init makefiles 'CCARGS=-DHAS_MYSQL
-I/usr/include/mysql -DUSE_SASL_AUTH -I/usr/local/include/sasl
-DDEF_SERVER_SASL_TYPE=\"dovecot\"' 'AUXLIBS=-L/usr/lib/mysql
-lmysqlclient -lz -lm -L/usr/local/lib -lsasl2'

The permissions on that file are so:
srwxr-xr-x 1 postfix postfix 0 Sep  9 14:38 /var/spool/postfix/private/auth
I've tried changin those but it didn't seem to matter.
