Is Mailbus 400 going to be made to route purely on a DDA? This is an interoperability problem with Microsoft Exchange that I didn't really understand until now. If you send mail from Exchange to a user via a connector such as SMTP over an X.400 backbone, then Exchange sends it to an X.400 address composed of the SENDING sites X.400 address with a DDA attached. If this goes over an X.400 connector to Mailbus 400 then the mail will get bounced back to the Exchange server which sent it and non-delivered as looping. Having talked to Microsoft they are routing purely on the DDA. Mailbus 400 currently doesn't route this way which means that this stuff just doesn't work. The requirement seems to be to get an X.400 address with a DDA of SMTP (changing to RFC-822 soon supposedly) and route to the right place based on just the DDA type, basically ignoring the rest of the X.400 addressing information. I don't know if there will be a problem on return mail to Exchange since I assume that if it hits an Exchange IMC then that will have a directory entry and be able to map the smtp address to an X.400 address and send if over the X.400 backbone correctly addressed. Is this being worked on? thanks, Mike

What you want should be possible without using DDA routing. As an example, the internal system I use has MAILbus 400 connected to SMTP via the MAILbus 400 SMTP gateway. Mail bound for (or coming from) the gateway has an O/R address with an RFC-822 DDA, and MAILbus 400 routes it just fine. The way this is done is by using a unique address stem for gateway addresses; in our case it is: C=GB; A=GOLD 400; P=INTERNET; DDA:[email protected] MAILbus 400 routes on the C=GB; A=GOLD 400; P=INTERNET part, and this works perfectly because nothing else uses that address stem. Taht is the correct way these things should be done. >> Exchange sends it to an X.400 address composed of the SENDING sites X.400 >> address with a DDA attached Is this configurable? If you can't tell Exchange what O/R address terms to use to get to an SMTP gateway via X.400, then Exchange is BROKEN. For Exchange to assume that its own address is a valid thing to use for someone else's gateway is completely ridiculous (it would be like me saying well, I don't know your O/R address, so I'll use mine and just change my name on it to yours and let someone else figure it out). That is where the problem lies in this case; DDA routing would just be a way to work around that problem, and it would be better to fix it at source. However, DDA routing is on the shopping list for future development. You should submit a formal product requirement to Geoff Oades@REO if this is a priority for you. Scott | |||||
3155.2 | exchange isn't configurable | GIDDAY::DRANSFIELD | Mike Dransfield, Sydney RSSG | Tue Apr 01 1997 11:46 | 8 |
It isn't configurable in Exchange hence the question. I am surprised that this hasn't been picked up since we are supposed to have an alliance.... I'll send mail to Geoff... cheers, Mike |
