Bug#911667: proftpd-mod-mysql: mod_sql.log is not rotated and grows bigger and bigger

[Paolo Benvenuto]

Package: proftpd-mod-mysql
Version: 1.3.5b-4
Severity: normal

Dear Maintainer,

In my system the file /var/log/proftpd/mod_sql.log is not rotated, I'm seeing that its content start from
when I installed the package, and now it's alread 9GB big!

I suppose that rotation must be implemented for this file.
