i was sure there would be dozens of answers to this by now. ok...
your question has two parts. part one is collecting mail:
now you could use sendmail's etrn feature. i don't know much about it,
but i think nick hilliard is a *huge* fan so i'll let him ramble on
about it.
alternatively you could use uucp - kenn humborg actually does like that
one, but sadly isp's don't. it actually is a shame because uucp is
rather nice. a uucp based napster would be pretty cool.
so what you'll really be using is fetchmail. you can either run it in
daemon mode (or guardian angel mode depending on how easily offended
you are) or you can run it from your crontab.
for sending it you do use sendmail. check out the install sendmail
script.
now, for how i do it. since my box can be connected at home, work
or directly through a modem, i do the following:
sendmail: it's configured to always queue mail, and i run it from
inetd, not as a daemon. see comments in inetd.conf, make sure
to turn off the sendmail startup.
fetchmail: fetchmail is set up to grab mail from two accounts but
it doesn't run as a daemon either. see the fetchmail man page
and fetchmailconf.
cron: cron runs a script once every 20 minutes. the script sees
if i have an internet connection and if so it runs fetchmail
and has sendmail process it's queue.
the script looks like:
# snip
#!/bin/sh

HOMEFIREWALL=xxxxx
HOMESUBNET=xxx.xxx.xxx
WORKSUBNET=xxx.xxx.xxx
# Am I connected at home?
/sbin/ifconfig eth0 > /dev/null 2>&1
if [ $? -eq 0 ]; then
/sbin/ifconfig eth0|grep -q $HOMESUBNET
if [ $? -eq 0 ]; then
rsh $HOMEFIREWALL /sbin/ifconfig | grep -q ppp0
if [ $? -eq 0 ]; then
fetchmail -s -t60
/usr/lib/sendmail -q
exit 0;

fetchmail -s -t60
