...Host down 450 error
I have GW 701. Today, the server can't send any email to two domains
(sympatico.ca and txt.bellmobility.ca) and getting error "450 Host down".
However, I was able to send email to both domain with hotmail. I tested the
connection and MX OK between my GW server and the two domains with GWIP.NLM.
Since I am able to send email with other system, it looks like the problem
is on my server. However, I have no idea where to look at. Could anyone

I am new to Groupwise and am trying to set it up. Netware 6.0 SP4 on all
servers, BM 3.7 latest patches running proxy and filtering, Groupwise 6 SP4.
I have the system setup and could yesterday send email messages back and
forth inside of my network but not to or from the outside world.
I then installed the GWIA and had three errors. One was not assigning a
postmaster - taken care of. The other two were "No relay host connectivity
from target server" and "Invalid or unspecified Internet Host name" - I
think that I took care of this one by filling in the Foreign ID ...450 Host Errors
At our district we can send out email (internally and externally) but we
can only receive email from within, not from an outside source. Some

Then I make the route.cfg in GWIA folder.
But the problem is can't fix.
Can you help me?
Make sure there's a hard return at the end of the line. Then remember that
existing emails in your defer folder will not get the change.

pinging the email server from the groupwise box, using the correct ip

We are experiencing errors on the GWIA agent, when sending emails to

Odd thing happening when co-worker sends message thru webaccess.
gwia log reports as follows.....
-detected error on SMTP command
-response: Host down 450 (db-arkitekter.fi)
-deffering message: ........
.......and the message never reaches me. It gets held in the "defer" folder.
What can be causing this?
Gwia is configured not to allow mailrelaying.
Have several domain-names configured in internet adressing.
Do I have to someway make all domain-names trusted?b How? Where?

Do you have a e-mail firewall system such as Proofpoint in place? We have
this happen when our firewall is having problems such as rebooting for
the coninuous updates that it receives from the vendor or an influx of
spam. Ususally the GroupWise "Agents/gwia/defer" directory will start
collecting items in it and that tells us that the mail is not going
through the firewall system. We then check our firewall box and 95% of
the time it is having a problem.
I hope this helps in your case.

We have a Groupwise 6 system, fully patched, sending out email trough a
smarthost configured in the GWIA. Everthing works fine, however when the
smarthost is unavailable for some reason, I get an 450 host down error,
but the mail doesn't end up in the defer dir, so the mail is lost....
As this is the production system, I just can't test it extensivly to
track it all down. Could it be the smarthost option make it work this
way? Or could it be GWIASIG(A free signature adding programm) that sits
in the third-party mail dir? Any thoughts or comment very appreciated!
Julia...Too many 450 host unknown errors
I just rebuilt a Small Business 5.1 server with GW 5.5 sp5 (gwia not
yet sp5 though).
I have the MX record pointing to mail.mydomain.com. When I ping
mail.mydomain.com, it replies from my routers IP address.
We also have a web site with the mydomain.com. If I ping
mydomain.com, it replies with the IP address of the website
(ISP/hosting company). I have our router forwarding all port 25 data
to our servers 192.168.1.2 address.
Mail seems to be going in and out for the most part, however, I am
getting a lot of 450 errors and most of them come up right after the
line that shows...error 450 host.domain.com down
GroupWise 6.5.7 agents on NetWare 6.5.6 server. Using a PIX 501 firewall.
The site has only one static public ip which is on the WAN interface of
the PIX. The server has only one Ethernet interface with a static private
address. The PIX receives messages from an external spam/anti-virus
outsource service over port 25 and limits the receipt of port 25 traffic
from just this outside source. The PIX then NATs this port 25 traffic to
the private ip address of the NetWare server.
Messages seem to go in and out OK, except that the GWIA routine shows a 450
host down and references the ...
