Some more information. Saslfinger -c gives the following output: /--------------------------------------------------------------------------\ saslfinger - postfix Cyrus sasl configuration Sa Jan 20 19:16:52 CET 2007 version: 1.0 mode: client-side SMTP AUTH -- basics -- Postfix: 2.1.5 System: Debian GNU/Linux 3.1 \n \l -- smtp is linked to -- libsasl2.so.2 => /usr/lib/libsasl2.so.2 (0x401a0000) -- active SMTP AUTH and TLS parameters for smtp -- No active SMTP AUTH and TLS parameters for smtp in main.cf!

Maybe the client side output doesn't play any role? If the statement " SMTP AUTH can't work!" is true why do I get error messages from the sql-plugin. Because of these it must be enabled, mustn't it? saslfinger -s seems to confirm that. So what's the use of this -c (client) option for a smtp-server(!)-addon? /--------------------------------------------------------------------------\ saslfinger - postfix Cyrus sasl configuration Sa Jan 20 19:25:33 CET 2007 version: 1.0 mode: server-side SMTP AUTH -- basics -- Postfix: 2.1.5 System: Debian GNU/Linux 3.1 \n \l -- smtpd is linked to -- libsasl2.so.2 => /usr/lib/libsasl2.so.2 (0x401a0000) -- active SMTP AUTH and TLS parameters for smtpd -- broken_sasl_auth_clients = yes smtpd_sasl_auth_enable = yes smtpd_sasl_local_domain = smtpd_sasl_security_options = noanonymous smtpd_tls_cert_file = /etc/postfix/smtpd.cert smtpd_tls_key_file = /etc/postfix/smtpd.key smtpd_use_tls = yes -- listing of /usr/lib/sasl2 -- insgesamt 952 drwxr-xr-x 2 root root 4096 2007-01-18 19:12 . drwxr-xr-x 45 root root 12288 2006-12-22 08:20 .. -rw-r--r-- 1 root root 13492 2006-08-08 00:40 libanonymous.a -rw-r--r-- 1 root root 851 2006-08-08 00:40 libanonymous.la -rw-r--r-- 1 root root 13824 2006-08-08 00:40 libanonymous.so -rw-r--r-- 1 root root 13824 2006-08-08 00:40 libanonymous.so.2 -rw-r--r-- 1 root root 13824 2006-08-08 00:40 libanonymous.so.2.0.19 -rw-r--r-- 1 root root 16298 2006-08-08 00:40 libcrammd5.a -rw-r--r-- 1 root root 837 2006-08-08 00:40 libcrammd5.la -rw-r--r-- 1 root root 16180 2006-08-08 00:40 libcrammd5.so -rw-r--r-- 1 root root 16180 2006-08-08 00:40 libcrammd5.so.2 -rw-r--r-- 1 root root 16180 2006-08-08 00:40 libcrammd5.so.2.0.19 -rw-r--r-- 1 root root 47520 2006-08-08 00:40 libdigestmd5.a -rw-r--r-- 1 root root 860 2006-08-08 00:40 libdigestmd5.la -rw-r--r-- 1 root root 43944 2006-08-08 00:40 libdigestmd5.so -rw-r--r-- 1 root root 43944 2006-08-08 00:40 libdigestmd5.so.2 -rw-r--r-- 1 root root 43944 2006-08-08 00:40 libdigestmd5.so.2.0.19 -rw-r--r-- 1 root root 13726 2006-08-08 00:40 liblogin.a -rw-r--r-- 1 root root 831 2006-08-08 00:40 liblogin.la -rw-r--r-- 1 root root 14028 2006-08-08 00:40 liblogin.so -rw-r--r-- 1 root root 14028 2006-08-08 00:40 liblogin.so.2 -rw-r--r-- 1 root root 14028 2006-08-08 00:40 liblogin.so.2.0.19 -rw-r--r-- 1 root root 31248 2006-08-08 00:40 libntlm.a -rw-r--r-- 1 root root 825 2006-08-08 00:40 libntlm.la -rw-r--r-- 1 root root 30692 2006-08-08 00:40 libntlm.so -rw-r--r-- 1 root root 30692 2006-08-08 00:40 libntlm.so.2 -rw-r--r-- 1 root root 30692 2006-08-08 00:40 libntlm.so.2.0.19 -rw-r--r-- 1 root root 20142 2006-08-08 00:40 libotp.a -rw-r--r-- 1 root root 825 2006-08-08 00:40 libotp.la -rw-r--r-- 1 root root 43184 2006-08-08 00:40 libotp.so -rw-r--r-- 1 root root 43184 2006-08-08 00:40 libotp.so.2 -rw-r--r-- 1 root root 43184 2006-08-08 00:40 libotp.so.2.0.19 -rw-r--r-- 1 root root 13886 2006-08-08 00:40 libplain.a -rw-r--r-- 1 root root 831 2006-08-08 00:40 libplain.la -rw-r--r-- 1 root root 14096 2006-08-08 00:40 libplain.so -rw-r--r-- 1 root root 14096 2006-08-08 00:40 libplain.so.2 -rw-r--r-- 1 root root 14096 2006-08-08 00:40 libplain.so.2.0.19 -rw-r--r-- 1 root root 21810 2006-08-08 00:40 libsasldb.a -rw-r--r-- 1 root root 852 2006-08-08 00:40 libsasldb.la -rw-r--r-- 1 root root 18692 2006-08-08 00:40 libsasldb.so -rw-r--r-- 1 root root 18692 2006-08-08 00:40 libsasldb.so.2 -rw-r--r-- 1 root root 18692 2006-08-08 00:40 libsasldb.so.2.0.19 -rw-r--r-- 1 root root 22168 2006-08-08 00:40 libsql.a -rw-r--r-- 1 root root 874 2006-08-08 00:40 libsql.la -rw-r--r-- 1 root root 22132 2006-08-08 00:40 libsql.so -rw-r--r-- 1 root root 22132 2006-08-08 00:40 libsql.so.2 -rw-r--r-- 1 root root 22132 2006-08-08 00:40 libsql.so.2.0.19 -rw-r--r-- 1 root root 273 2007-01-06 18:41 smtpd.conf -- content of /usr/lib/sasl2/smtpd.conf -- pwcheck_method: auxprop auxprop_plugin: sql mech_list: plain login cram-md5 digest-md5 sql_engine: mysql sql_hostnames: 127.0.0.1 sql_user: --- replaced --- sql_password: --- replaced --- sql_database: --- replaced --- sql_select: select password from users where email='%u@%r' log_level: 7 -- content of /etc/postfix/sasl/smtpd.conf -- pwcheck_method: auxprop auxprop_plugin: sql mech_list: plain login cram-md5 digest-md5 sql_engine:mysql sql_hostnames: 127.0.0.1 sql_user: --- replaced --- sql_password: --- replaced --- sql_database: --- replaced --- sql_select: select password from users where email='%u@%r' log_level: 3 -- active services in /etc/postfix/master.cf -- # service type private unpriv chroot wakeup maxproc command + args # (yes) (yes) (yes) (never) (100) smtp inet n - - - - smtpd -vvv pickup fifo n - - 60 1 pickup cleanup unix n - - - 0 cleanup qmgr fifo n - - 300 1 qmgr rewrite unix - - - - - trivial-rewrite bounce unix - - - - 0 bounce defer unix - - - - 0 bounce trace unix - - - - 0 bounce verify unix - - - - 1 verify flush unix n - - 1000?
