Thanks for the reply, first off.
Just to make sure I was doing what I thought I was doing,
I did the following experiments.
I have a test box that delivers mail locally. If it thinks it
shouldn't, for whatever reason, it sends the mail to the regular
mail server and it delivers it. So, if I'm right, a "good" result
is when it's delivered locally, and a "bad" result is when the
mail gets shoved over to the regular channels.
The variables are:
relay_recipient_maps
recipient_canonical_maps
myorigin
Now, my understanding is that myorigin applies when sending mail.
It basically alters what the "from" address looks like to the
ultimate recipient.
With both relay_recipient_maps and recipient_canonical_maps defaulted,
I sent mail like so:
mail -s "gl bbb 12" g...@bbb.arlut.utexas.edu < /etc/motd
bbb isn't a machine here.
myorigin set to nothing -- postfix won't start. Makes sense.
myorigin = crelm.toothpase -- postfix starts, the mail isn't delivered.
Makes sense.
myorigin = shoogams.$mydomain -- delivered via regular channel (bad), w/
from address of shoogams.$mydomain . The "from" address I expected.
I was hoping it would be delivered locally, but my production
machine wasn't doing that either, so if I have some other
combination of things wrong, then... then I'm wrong. But this
result is consistent w/ what I've seen before.
myorigin = $mydomain -- the default, and what I've had in place on my
production boxes all along -- delivered through regular channels
(bad) but has the "from" address I want.
So, eliminating myorigin as a variable.
In the rest, here are the two non-default values of these variables.
I had previously decided that relay_recipient_maps wasn't what I
wanted, but some other things happened to make me wonder. So I
tested it.
relay_recipient_maps = regexp:/etc/postfix/pfrecipient_canonical
recipient_canonical_maps=regexp:/etc/postfix/pfrecipient_canonical
var/ value y= value above, def= defaulted
rel... y def def y
recip... def def y y
myorigin $mydomain throughout
result reg/bad bad good/locally
To my eyes, this means myorigin does do good things when defaulted,
but it doesn't do what I wanted/hoped. It appears to me that
what I need is recipient_canonical_maps set to the value above
in order to get what I want.
Or am I missing something?
