re: how to logrotate files
If you have logrotate installed (chances are you do) then there should be a few files in /etc/logrotate.d that you can look at to give examples of how to use logrotate to do daily log rotations. The format is fairly straighforward - the names of the files to be rotated, follwed by a list of configuration options in {}. The /etc/logrotate.conf file contains system wide defaults.
Look at the man pages (man logrotate) to find out what the options mean and pay particular attention to the 'create' and 'copytruncate' sections. Since your script is running out of cron you likely don't need to worry about signaling it to start a new log file, however you will want to be careful about what would happen if logrotate runs at the same time as your script.
Logrotate itself is called by cron once per day so if you need more frequent log rotation you'll need to set that up manually. You can look at the /etc/crontab file to find out when the scripts in /etc/cron.daily folder are going to be run. (That's where logrotate is called)
Cheers,
Anthony

bf_tar
BF_TAR(1) Bogofilter Reference Manual BF_TAR(1)
NAME
bf_tar - shell script to write a tar file of a bogofilter directory to stdout
SYNOPSIS
bf_tar [-r] [-R] bogofilter_directory
DESCRIPTION
bf_tar bundles a bogofilter working directory in tar format and copies it to standard output (your console, or where you redirect it, see
EXAMPLES below).
OPTIONS
The -r option causes bf_tar to remove inactive log files after the archive has been written successfully. The default is to leave log
files.
The -R option causes bf_tar to remove inactive log files before the archive is written. This may reduce chances that the resulting archive
is recoverable should it become damaged. The archive may be smaller though. The default is to leave log files.
EXIT STATUS
The script exits with status code 0 if everything went well, and nonzero if it encountered trouble.
EXAMPLES
o bf_tar ~/.bogofilter > outfile.tar
Writes a standard .tar file containing the essential files from ~/.bogofilter to outfile.tar.
o bf_tar ~/.bogofilter | gzip -9 -c > outfile.tar.gz
Writes a gzipped .tar.gz file containing the essential files from ~/.bogofilter to outfile.tar.gz.
o bf_tar `pwd`/mydirectory > outfile.tar
Prepend $(pwd)/ or `pwd`/ if you want to specify an absolute path instead of a relative path.
NOTES
This script is meant for use with Berkeley DB based bogofilter versions.
This script requires a SUSv2 compliant pax utility.
This script expects a SUSv2 compliant shell. Solaris systems should have the SUNWxcu4 package installed (when bogofilter is configured) so
that /usr/xpg4/bin/sh can be used.
