One solution that pops up on me is to get a pop3 account on the host and use fetchmail. But you can most likely do that with your isp, too. I think you should not let people send e-mail directly to your box if you are not on a permanent connection with a computer switched on 24/7. fetchmail can run as a daemon and check mail at regular intervals. I think this would be an interesting option in this case. I am sure the 'go online' script can also start fetchmail for different users [1] and the 'go offline' script can kill all fetchmail daemons running. Remco [1] you probably want to use something like ( sleep 10 ; su username -c 'fetchmail --daemon 900 --all --syslog' ) & in the script, assuming the script runs as root. Note that I have not tested this. I have absolutely no experience with Linux on dialup lines, but I do use fetchmail. -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word "unsubscribe" to [EMAIL PROTECTED] . Trouble? e-mail to [EMAIL PROTECTED] .
