sending mail on lan...

[Jerry LeVan]

Uggh,

Yesterday I screwed up the postfix config so bad that I could
not even send my to myself...

Fortunately I was able to recover the error.

By setting:
mynetworks = 192.168.1.0/28, 127.0.0.0/8

I was able to send to other machines on my lan
by using strings like

    user@[192.168.1.xxx]

as the address.

It appears that if a "name" is used ie jerry at server.localdomain
that a name lookup occurs an one gets an error on a "A" address
lookup.

I enabled Flat Files in Directory Access, but nothing changed...

I peeked at netinfo and thought that perhaps adding a "machine"
entry might help, but could not figure out the "serves" entry.

Dan Shoop suggested reading the lookupd man page, but found it
to be relatively opaque...

My current strategy is to have reports send to me on the machines
where the report is generated I have installed qpopper on the
macs and on my main work machine I have Mail accounts that look
for mail for me on the other machines....

The linux box runs smtp and has a "caching name server" ( of which
I know nothing...) and does not have any problem sending mail to
the other machines on the lan.

It is interesting that the host command fails for linux and macs
on the lan.

So, is there something I can do with Directory Access, NetInfo and
Lookupd so that I don't get lookup errors in the mail system for
machines on  the lan?
