Hi,
I am hosting my own mail server at home and my ISP blocks port 25. I have to use port forwarding (classic 25 -> 2525). I am forced to use PREF = 5 for my server's priority.
I am trying to overcome the case where my server goes offline (say power outage for example) and would like to implement mail mapping (@LOCAL) as a fallback solution. So I need to have my server's DNS tried first (on port 2525) and if it fails get ZoneEdit to parse and forward each email to some specified address.
From my testing, it appears that ever since I specified my new mail map, it looks like it took over all email management and it just parses and forwards each email address to the specified address (I keep track of email statistics on my server and they all fell to 0 since the mail mapping)
With all this, what I am suspecting is that LOCAL (which is supposed to be the back up and cannot be specified explicitly in the MX section, it is implicit), has implicitly a lower PREF (likely 0) than my server's DNS PREF (forced to 5 because I am forwarding to port 2525), so any incoming exchange is just parsed and forwarded instead of attempting to "blindly" deliver as-is to my mail server.
Anyone's got an idea on how I could get my server (with the 2525 forward) to take precedence over ZoneEdit's LOCAL email handler?
Happy holidays folks!
