Tomato, WRT54G and email checking

    I am using Tomato on WRT54G, and would like to put a script on it that would turn the white led on when there is a new email on my email account.

    Is there any binary, able to check a POP3 email account, preferably POP3 with SSL as well (needed for gmail), small enough to fit on the Tomato's 700kbytes JFFS, to use in a script ?

    Please don't tell me to google for such an app source and compile/port it myself, i don't have the necessary setup to do this. Getting a linux machine up with whatever needed to cross-compile anything for WRT54G would be way too much hassle for something as stupid as turning a LED after an email check :)

    And, btw, just in case Tomato devs read the form, thanks a lot for a great firmware.

    Well, nobody responded, so i did this the quick and dirty way, using a simple shell script. Just in case someone may be interested in the same thing or may have some idea on how to improve it, i am posting the script here.

    1. Unencrypted POP3 only, no SSL (read - gmail POP3 won't work)
    2. The script should be cron-ed to run every 5..10 minutes
    3. I am not any good at shell scripts, so please post your comments/fixes, 10x

    ### script config here ###
    ### telnet to pop3 server, login, retrive stats and quit ###
    	sleep 1
    	echo "USER $USER"
    	sleep 1
    	echo "PASS $PASS"
    	sleep 1
    	echo "STAT"
    	sleep 1
    	echo "QUIT"
    } | telnet $SERVER $PORT`
    ### remove \r-s, get the +OK count and stat result (if present) ###
    OUTPUT_STR=`echo $OUTPUT_STR | tr -d \\\r`
    OK_COUNT=`echo $OUTPUT_STR | sed 's/+OK/\n+OK/g' | grep -c +OK`
    STAT_RERSULT=`echo $OUTPUT_STR | awk -F '\+OK ' '{print $5}'`
    ### we have used 4 commands, all should be +OK-ed ###
    if [ "$OK_COUNT" == "4" ]; then 
    	led amber off
    	# turn the white led on if we got some messages
    	if [ "$STAT_RERSULT" != "0 0" ]; then 
    		led white on
    		led white off
    	led white off
    	led amber on

    As a solution to his problem I will try another approach:
    I will create a simple SMTP Server application (that can be stored in the /jffs/ folder and called in the start-up script) that will be listening on port 25 (of course) and will light up the amber or white led of the linksys router when I receive an email.

    In order to be able to see when I get an email from gmail - I will set gmail to forward incoming mails to my router.

    I'll be back with the source code of the program and the output file of the VoidSMTP server soon.
