I'm using postfix on slink to do this now. It's been a while since I set it up so I may be a little vague about some of the details, my notebook with my debian notes has gone missing. Do you have a domain already? If you do, see if your isp will do uucp delivery for you. My home lan gets its mail via uucp from my desktop machine at work. If you don't have a domain and are unwilling to pay for a top level domain, talk to the folks at dyndns.org about getting a subdomain from them. To do this (from vague memory, there may be a little more to it than this) 1) set up a uucp link between your home gateway machine and your isp. There is a howto on this, so I won't go into detail. 2) set up your domain's dns so that your isp is the mx for your domain. 3) have your isp configure their end so that all mail for your domain is transferred via uucp to your machine. 4) Set up your home machine to send all mail outside your domain to your isp (check out the postfix faq for details) via uucp. This isn't totally necessary if you have a fast link - I have a cablemodem and do all my outgoing delivery myself. 5) Set up your ip-up script to add a call of 'uucico -S ispuucpname' to force a connection to pick up your pending mail & send out your outgoing queue. 6) add a cron job to do 'uucico -S ispuucpname' every hour or so to pick up your mail If you want to have incoming uucp over tcp and use a seperate password file for uucp (recommended), put the password entries into /etc/uucp/passwd and add uucp stream tcp nowait root /usr/sbin/tcpd /usr/sbin/uucico -l to your inetd.conf and then kill -HUP inetd When I was using diald and ppp for a dialup connection, I had my ip-up script touch /var/run/linkup and then had ip-down remove it. Then I could have cron jobs check to see if the link was already up before doing anything. The big advantage of having your mail come in over uucp is that it will resume interrupted transfers where they left off, rather than making you retransmit the whole message. Very nice if you have timed local phone service. If your own isp won't do this, there are companies out there who will, including the consulting firm I work with (http://www.communiweb.net). jpb -- Joe Block <[EMAIL PROTECTED]> CREOL System Administrator Social graces are the packet headers of everyday life.
