The problem with blat is that you have to setup stunnel to use it with gmail, and that is often problematic. Instead a replacement for it is MailWrench Below is a replacement for the blat batch file at Keep a Record of POPFile's Statistics Over Time page

mail_bucket_stats.bat

wget -O - http://127.0.0.1:8080/buckets >> bucket.html
mailwrench -to [email protected] @m.cfg -s "POPFile Buckets Report" -file bucket.html -html 
# For those that have the GNU Win32 utils installed
# uncomment rm statement and comment/delete del statement
#rm -f bucket.html
del /F /Q bucket.html
cls
@exit
