Your original post did not indicate a problem you are having. The only question you asked was "Besides /etc/postfix/main.cf, is there any other files that need to be edited to enable this mail relaying?”. Was this an oblique way of saying “it’s not working, what else do I need to change” or are you just asking what else needs to be changed? It’s not clear if you’re still setting up the new system or if you’ve tried to run it and there’s a problem.
The answer to your question is “master.cf as well as any files referenced in main.cf”. The better way to compare the main.cf files is to do a postconf -n on both. That displays only the parameters that have been changed from their defaults. Easier than scanning through a long main.cf looking for uncommented lines. OTOH, if you are trying to run it and it’s not working, providing more information as requested in the list’s welcome message will help. As it says there: TO REPORT A PROBLEM see http://www.postfix.org/DEBUG_README.html#mail That includes a list of what is required. -- Larry Stone lston...@stonejongleux.com > On Mar 17, 2017, at 7:36 AM, paul.greene.va <paul.greene...@verizon.net> > wrote: > > Maybe you're in an environment where you get to decide which equipment, > applications, whatever you want to use, but for some of us, this was already > decided long before we got there.
