Alternatively, if you want to SMTP over email for a domain over the dialup connection, assign the PPP client a primary MX record and a fully connected server on the PPP server's network a secondary. The PPP reconnect script on the client can be instrumented to flush the outgoing queue and also send email to pseudo alias on the secondary MX server that triggers a flush of its incoming queue for your domain. You have to make sure you dialup at least once every three days or so.
This strategy requires the PPP client have a static IP.
No, it doesn't, or at least it won't after the dymamic DNS stuff is finished. Dave -- Dave Siegel President, RTD Systems & Networking, Inc. (520)318-0696 Systems Consultant -- Unix, LANs, WANs, Cisco dsiegel@rtd.com User Tracking & Acctg -- "Written by an ISP, http://www.rtd.com/ for an ISP."
