Good afternoon all,
I am considering setting up a nolisting postfix server on a spare
static IP
so as to study the effects of nolisting for some heavy domains we host
(3k
total msgs/day, 200 legit).
In what sense are those "heavy?" The spam/ham ratio is a bit low and the
total flow is similar to what I see on vanity domains with a handful of
users.
This server will sit at both the highest
priority and the lowest priority, with the real MX in the middle.
The nolisting spec says that nothing should answer on port 25
For a good reason: this is critical to the tactic.
but I would
like it to answer and respond with a "not available" error, so that I
could
compare connections between the nolisting MX and the actual MX.
That will break mail for the domain. Badly.
If you don't understand this from the documentation of nolisting, you
probably shouldn't be trying it.
