One question; this will absolutely expose real domains, machine names, and such. I wouldn't normally do that on a web forum, and might on a mailing list, except for all of the web archives this list feeds. Is there *any* future downside to exposing that real-world information? Or is this common practice here and I am being paranoid? > http://www.postfix.org/BASIC_CONFIGURATION_README.html > http://www.postfix.org/STANDARD_CONFIGURATION_README.html I had skimmed these, and know I need to scan them properly (on the list for tomorrow morning), but they tend to make the assumption that one is setting up a fresh new mail server. I am migrating an old production machine with many domains and rather large external files (virtusertable, access, etc.) controlling various mailing list servers and other mail requirements that all need to move to the new postfix install before I can switch the MX records to it. I would have thought there would be many web pages dealing with the migration from sendmail to postfix, but I basically found ONE so far ( http://www.nmmm.nu/postfix.htm ) that details using various pre-existing sendmail config files in postfix, and I suspect that one is out-of-date enough to be causing (or at least not solving) my first "simple" problem. If I missed anywhere on the web where moving from sendmail to postfix while using (or modifying) existing external files is discussed in detail, pointers would be appreciated - might save me from making a bunch of embarrassing newbie posts here...
