Hi all,

I really don't know what sql is related here, but I neither a uncommented sql
string in the main.cf nor /etc/sasl/smtpd.conf, although, I don't know who
exactly is complaining here. is it because SASL wants to load the sql plugin,
or is it postfix (didn't know it has one).

However, when trying to google for this error messsage, I can find alot, but
nothing related to me, as I definitely want NOT to use sql in any of these
cases, but I still keep getting this error (don't know how to suppress):

May 31 13:28:42 sparta postfix/smtpd[13371]: sql_select option missing
May 31 13:28:42 sparta postfix/smtpd[13371]: _sasl_plugin_load failed on
sasl_auxprop_plug_init for plugin: sql

of course, "sql_select" statement is missing because I did not specify it
somewhere - in fact, do don't even want to load the sql plugin get loaded it
tries to load anyway. But where is it specified? can't find any hint
(unfortunately).

Please let me know if you need some configs to help me tracking down this
issue...

Many thanks,
Christian Parpart.
