#
# This shell script is used as a "frontend" for running fetchmail. It will
# start up fetchmail and save the session to disk, generate statistics
# of the e-mail that you downloaded, and tell you how many messages
# you have in various folders. A copy of these results are also
# e-mailed to you.
#
# An rc file is also supported. If the file $HOME/.runfetchmailrc
# exists, it will be sourced. This way, you can place runfetchmail
# into /usr/local/bin, and individual users can have their own settings.
#
# Pre-requisites: You must have procmail, or at least `mailstat', a
# utility that comes with procmail, running on your system. You must
# also have `timer', a shell script written by me, if you would like the
# total time that the transfer took to be displayed.
#
# Syntax: runfetchmail [-every]
# -every Downloads all messages from the mailserver, regardless of
# their size and whether they have been previously downloaded.
#
# Changes in version 1.1: The argument "-every" is supported. I removed the
# $EXIT_CODE variable since I had problems assigning the exit code from
# fetchmail to it.
# Command line to run fetchmail
FETCHMAIL="/usr/local/bin/fetchmail"
# Your procmail logfile
LOG=$HOME/procmail/log
# Do we want to use timer? Set to 0 to disable.
TIMER=1
# Our path to sendmail with parameters
SENDMAIL="/usr/bin/sendmail -oi -t"
# Who am I?
SELF="dmuth@ot.com"
# The folders that I should check for the number of messages
FOLDERS="$MAIL $HOME/mail/lists"
# Number of seconds to "sleep" for while procmail finishes up, increase
# this if you have a really slow system
LATENT=10
# Do we want to use mailstat? Set to 0 to disable
MAILSTAT=1
# Do we want to e-mail the output to myself? Set to 0 to disable.
# I strongly suggest doing this so that if you lose your connection to
# the net part of the way through a download, you can see how much
# progess was made

clear
# Do the same thing with the statistics
test $E_MAIL -eq 1 && stats $@ 2>&1 |tee -a $TMP || stats $@
# Now send $TMP to myself and clean up the mess
test $E_MAIL -eq 1 && { cat $TMP |$SENDMAIL; rm -f $TMP }
# cleanup the log file for next time
rm -f $LOG
