GWIA: 450 host down...on a host that is NOT down
i'm getting an annoying 450 host down error on my GWIA. We sent some
important emails and we didn't notice they were not going out until
later. Then we checked and we were having 450 host down on that host.
Some time ago we used to experience this very same problem, but then
stopped (couldn't say exactly what we did, since I was not in charge
communications back then)
Obviously, I did a telnet on port 25 to the mail exchanger of the
problematic domain. It was up and running.
What could be causing this behaviour? How can I solve this probl...gwia and 450 Host down for own domain

mostly dealing with failed deliveries of emails for one (real) reason or

Most of these are from <> ie null sender.
Inbound mail from other domains (ie the internet at large) seems ok.
Outbound mail to other domains is likewise ok.
Caveat: AOHell and now Hotmail, but that's not GWIA's fault - they have

The mail control company that we use for sending / receiving mails uses
two mail clusters. Currently we have two GWIAs for sending mail (a
production and a disaster recovery), we have one of the GWIAs configured
to send mail via one of the clusters (cluster-d.mailcontrol.com) and the
other GWIA to send via the other cluster(cluster-f.mailcontrol.com). Is it
possible to put two entries in the relay host for outbound messages field
in the GWIA; this would allow us to use both mail clusters on both of the
GWIAs.If this is possible does anybody know the correct syntax for doing

I have a new v7 GWIA on a new domain that is using the relay settings

Anyone seen this before?
Check your GWIA.CFG file as anything in there will override settings
from eDirectory. I think the switch is /mh which is your Mail relay
If that isn't it, when you say it's a new GWIA, is this a new GWIA

I'm getting a 450 Host Down message on GWIA only when sending to 1

I tried creating a Route.cfg with the ip address up the remote domain and
still got the same condition.

We have setup a new GW 7 server and are using our existing sendmail
(resides in DMZ) server as our relay host. We can successfully send mail
from GW to our internal users and we can also transmit externally.
We cannot get mail to transfer from our existing system to GW. A packet
trace shows traffic going to our GWIA. I don't see anything showing up in
our GW logs. It would be great to have an error message on the GW side to
research. We just get a return email message back from our mail server

GWIA Documentations states that you can use multiple outbound relay
hosts, but does it round robin the outbound or use the first until it
fails or what ?
