One of those BBSs is the AMPRnet gateway for the rest of them (well, the gateway is on linux, but you get my meaning). That machine also has an RF interface on the local BBS forwarding network frequency. So it will also be my gateway machine to the traditional BBS forwarding network.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>My question is about the best way to send mail from my non-gateway machines, through the gateway, to the traditional BBS forwarding network. Of course, the return path needs to work as well.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Within my network, mail (non-bulletin messages) travels via SMTP. As soon as a message is created, it is sent to the destination. The same is true when sending messages out to BBSs on amprnet. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>But when the gateway machine has a message to send to the traditional BBS network, the gateway’s rewrite rules drop it in a local mailbox and then the message is forwarded the next time “mbox timer” expires or “at mbox kick” is used. So I’m wondering how to configure the non-gateway machines that need to send messages to the traditional BBS network.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>One way, I suppose, is to have the non-gateway machines do the same thing that the gateway machine does. Specifically, drop mail addressed to the traditional BBS network into a local mailbox and then, at the next forwarding interval, forward it to the gateway machine, which will drop it into a local mailbox and then, at the next forwarding interval, forward it to the forwarding partner. That’s simple and straight forward. But it incurs two delays. One delay is waiting for the next forwarding interval to occur between the non-gateway machine and the gateway machine. Then a second delay occurs waiting for the next forwarding interval to occur between the gateway machine and the forwarding partner.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>(Note: I realize, of course, that these hop-by-hop delays will occur all along the forwarding path in the traditional BBS forwarding network. Therefore, in the general case, one more hop delay is not a big deal. But in the case where most of the traffic will be going no more than one forwarding hop away from the gateway machine, eliminating the second hop cuts the time in half. And since the majority of the use of our BBS system is for ARES/RACES activity, it is desirable to reduce the delay as much as possible.)<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>So, I’m wondering if a better way is to somehow cause the non-gateway machines to use SMTP to get the message to the gateway machine, where it could then be forwarded. This would cause the mail to be sent right away from the non-gateway machine to the gateway machine, eliminating one of the delays.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I experimented with rewrite rules like: <a href="mailto:user@bbs.#nca.ca.usa.noam">user@bbs.#nca.ca.usa.noam</a> <a href="mailto:user%bbs.#nca.ca.usa.noam@gatewaybbs">user%bbs.#nca.ca.usa.noam@gatewaybbs</a><o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>This did, indeed, ship the message off to gatewaybbs right away via SMTP. But it was rejected by the gatewaybbs JNOS machine saying relaying was not allowed. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>So I’m wondering what others do that have this type of local network with a gateway that can talk to the rest of the traditional BBS network. Do you just use the same forwarding method or do you do something more elegant to get the message to the gateway via SMTP right away?<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks in advance,<o:p></o:p></p><p class=MsoNormal>Michael<o:p></o:p></p><p class=MsoNormal>N6MEF<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
