Hello everybody, thanks for reading this.

A client of ours (hotsocket.com) recently decided to take over their own
mail and dns, and to leave just the web site hosted with us.
Now, There web site generates a fair amount of email. But something went
wrong in the switch, and now the messages bounce like this:


**********bounce message pasted below***********

Hi. This is the qmail-send program at outlier.axl.net.
I tried to deliver a bounce message to this address, but the bounce bounced!

<[EMAIL PROTECTED]>:
Sorry, I wasn't able to establish an SMTP connection. (#4.4.1)
I'm not going to try again; this message has been in the queue too long.

--- Below this line is the original bounce.

Hi. This is the qmail-send program at ghost.axl.net.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

Background information


Solstice.axl.net is the webserver that the site is on.
It has default control files, except that there is no rcpthost, and
qmail-smtpd is not running on it.
It also has this:
matt@solstice:/var/qmail/control > cat smtproutes
:smtp.axl.net


anything mailed from solstice seems to get delivered to smtp.axl.net just
fine, the log have a line like:

"Mar 23 12:30:05 solstice qmail: 953832605.093367 delivery 55267: success:
216.66.11.20_accepted_message./Remote_host_said:_250_ok_953832605_qp_24843/"

for every mail, and solstice's queue is always empty.


Outlier.axl.net is another qmail box, and has the address 216.66.11.20.
smtp.axl.net is an A record to the same address, 216.66.11.20.

This box is set up so that nothing is delivered locally, It was designed to
handle all remote deliveries for all of our servers.
It has default config files, except for concurrencyremote, which is set to
500 (thanks suse!)
and queuelifetime, set to 250000.

Ghost.axl.net, at 216.66.11.19 is the box that handles mail for domains that
we control. It does local deliveries for about 100 domains using vpopmail.

ghost has
:smtp.axl.net
in its smtproutes file.


As far as I understood it, things should work like this.




a message created on solstice, to a domain we do mail for, say [EMAIL PROTECTED]
would take the following path:

solstice.axl.net->smtp.axl.net(which is outlier)->ghost.axl.net
and on ghost it would get delivered to the right maildir.

a message created on solstice to a outside domain, like [EMAIL PROTECTED]
should go like this

solstice.axl.net->smtp.axl.net(which is outlier)->best mx for hotsocket.com
it can reach.


root@outlier:/var/qmail/control> host -t mx hotsocket.com
hotsocket.com mail is handled (pri=10) by smtp.hotsocket.com
hotsocket.com mail is handled (pri=30) by solstice.hotsocket.com
