Question postfix/smtpd: could not find auxprop plugin, was searching for sql_sqlite3

[Stephen_Stephen]

the postfix is down for unknown reason, restarted it email cannot be sent/received. I have these errors in /var/log/messages :

postfix/smtpd: could not find auxprop plugin, was searching for sql_sqlite3
....

plesk version 12.0.18

what/where should I be looking at

Thanks

Sounds similar to Can't authenticate to send mails (Postfix) ...

It shows nothing when typing: rpm -qa | grep -i saslauthd

Is this normal or what is the actual module name

 

[Stephen_Stephen]

Here is the postfix smtpd.conf file:
/usr/lib64/sasl2/smtpd.conf:

pwcheck_method: auxprop saslauthd
auxprop_plugin: sql_sqlite3
saslauthd_path: /private/plesk_saslauthd
mech_list: DIGEST-MD5 CRAM-MD5 PLAIN LOGIN
auto_transition: yes
sql_engine: sqlite3
sql_hostnames: localhost
sql_database: /plesk/passwd.db
sql_select: SELECT FROM domains d, users u WHERE u.name='%u' and d.name='%r' and d.status=0 and u.status=0 and u.dom_id=d.id
sql_verbose: yes
log_level: 9

the above conf file looks right

the sqlite and cyrus-sasl were installed

rpm -ql sqlite-3.7.9-1.el6.art.x86_64
rpm -ql cyrus-sasl-2.1.23-15.el6_6.2.x86_64

restart services:

/etc/init.d/saslauthd restart
/etc/init.d/postfix restart

the error persists in /var/log/messages:

"postfix/smtpd[21064]: could not find auxprop plugin, was searching for sql_sqlite3"

What did I miss

 

[Stephen_Stephen]

latese error from /var/log/messages

postfix/smtpd[23411]: SQL engine 'sqlite3' not supported
postfix/smtpd[23411]: auxpropfunc error no mechanism available
postfix/smtpd[23411]: could not find auxprop plugin, was searching for sql_sqlite3

If it worked before and then stopped, have any system updates been installed on the system? (Rolling back the latest updates might fix it; it is just an idea of what makes sense to check).

 

[Stephen_Stephen]

There is no update and should not be as it's plesk12 centos 6.1 quite old server
confirmed by:

#rpm -qa --last

no update found in last two years

did I miss anything
thanks
