CL> your select query is:

CL> SELECT CONCAT('/var/spool/mail/','$(domain)','/','$(local_part)'),

CL> LIKE does a case-insensitive compare. So John.Smith is

CL>     SELECT CONCAT(..., LOWER('$(local_part)')), ...

My fault. You're right. Now is working. I don't know why I thought
that this line :   /var/spool/mail/$(domain)/$(local_part) is
responsible for this error. Now is working well thx.

Of course that was my wrong SQL query.
