In that export process, the information is changed from the IMail format to something Postfix can use. On the Postfix side you will have a lookup that has something like this: [EMAIL PROTECTED] OK [EMAIL PROTECTED] OK [EMAIL PROTECTED] OK [EMAIL PROTECTED] OK [EMAIL PROTECTED] OK [EMAIL PROTECTED] OK Now, you may have OK, you may have DUNNO, it depends on exactly what implementation you choose. Now lets say you have example.net, and bar.com that use the aliases to accept all email. Your script needs to add these to the list in something along the lines of this: example.net OK bar.com OK The exact rules for order of evaluation are here: http://www.postfix.org/access.5.html The reason you might use DUNNO vs OK is an entire different discussion. If you are using someone's pre made solution, you just need to add a DUNNO or OK depending on what they use. Because of this, I do not think it is worth it to go over DUNNO vs OK at this time. Sorry for the delay in sending this, but I have bin interrupted about 5 times for a total of over 3 hours while writing the reply. --Eric
