Hey all,
The dayjob is attempting to tie VERP into our ticket system (RT with
postfix), and it would be useful to encode not just the magic "from"
address, but ideally the ticket number as well, so that a bounced reply to
the customer can be added to the ticket stream.
So if normal verp (per

Hey there all,
At the day job, we periodically do an export of our ticketing system into
an internal alias where the alias does an :include:.
However, recently, outlook365 decided it did not like having

have that in t

Hey there,
We run validating resolvers at the day job, but by default not on the box
where postfix runs. (I.e. we rely on the AD bit).
In reading over what's required to enable DANE support in postfix, I see
that there's a compile-time requirement for the DNS lib in the OS to
support it, wh

I'm in the process of vetting historical postfix configs -- comparing so
many things in a historic config where prior employees overrode the
defaults and perhaps why.

Hey there all,
I've wondered this a while. It seems the old Sendmail access maps, and
following that postfix have managed to allow you to apply a rule on things
like:
CONNECTED VIA specific IP.
FROM a specific mailbox

But never more than one of these.

Hey there,
We have an interesting problem, at the dayjob.
We recently decommed a site, as in, removed it from forward DNS, but it's
still sending us root mail, which postfix is rejecting with unknown
hostname. (Totally reasonably)
Now, it's sending using an SSL cert that we've marked as tru

A cross post because there's enough dmarc discussion to be relevant.
We've just released OpenDMARC 1.4.1 over at

All,
The dayjob has a number of machines out in the wild that need to be able
to send mail (mostly from cron jobs) home to the mothership. Not all have
controllable reverse DNS. It's an issue with donated colo and transit.
Doing a bunch of tunnels would work but it's a really stupid answer.
All,
Apologies that this isn't postfix software specific.
Because it gets discussed enough here, myself and the others on the
opendmarc team are coming pretty close to releasing opendmarc 1.4.1, which
includes a lot of rework to both our own inbuilt SPF handling code, as
well as a number of o

Postifix has a concept of quarantine. It is called the HOLD queue.
As of 2006, when the Milter says QUARANTINE, then Postfix will
quarantine the message, i.e. place it in the HOLD queue, for admins
to deal with manually.
