[ILUG] another useful laptop bit...

[kevin lyda]

add this line:

O DeliveryMode=d

to your sendmail.cf.  (or use an mc file, or the install-sendmail
script)  that way there'll be no problem when you're not connected. 
then write a shell script to go through your queue when you're
connected.

normally i'm only online when my ip address is 192.168.5.xxx, and the
ppp0 interface is up on my home machine named inle.  the following
confirms all this and if so it runs /usr/lib/sendmail -q to send all my
email.  then have crontab (see man 5 crontab) fire it off.

---snip---
#!/bin/sh
#####
# Is there mail to send?
mailtosend=`mailq|wc -l`
if [ $mailtosend -eq 1 ]; then
    exit 0;
fi
#####
# Am I connected at home?
/sbin/ifconfig eth0 > /dev/null 2>%1
if [ $? -eq 0 ]; then
    /sbin/ifconfig eth0|grep -q 192.168.5
    if [ $? -eq 0 ]; then
	rsh inle /sbin/ifconfig | grep -q ppp0
	if [ $? -eq 0 ]; then
	    /usr/lib/sendmail -q
	fi
    fi
fi
