HI Peter,
Welcome to SBS newsgroup.
Issue description:
============
I understand that your Exchange SMTP server connection will drop to send
outbound email short time after booting.
Analyzing and suggestion:
==============
Before we go any further for troubleshooting this issue, please kindly
rerun CEICW to make sure that Exchange server is configured correctly, from
your description, it seem you are using smarthost on ISP to relay your
internet emails. So please make sure that you input all the setting
correctly. You can refer to the KB article below:
825763 How to configure Internet access in Windows Small Business Server
2003
http://support.microsoft.com/?id=825763
After running the wizard, we need to focus on the Exchange transport issue,
it seems your outbound email on ISP smarthost need some special
configuration, in order to narrow down the issue more clearly, please refer
to following KB article for more information:
827601 Cannot send external mail when your smart host server is different
from
http://support.microsoft.com/?id=827601
Please kindly go through the steps in the KB article above, it should be
helpful to your issue.
Please also make sure that if you have router installed on your SBS domain,
you need also open port 25 on the router.
For the exchange error, we found it should not relate with outbound emails.
We can first focus on the outbound email issue.
Thanks for your time and effort on this issue, please feel free to go
through my suggestion and post back your results. I am glad to be of
further assistance.
Best regards,
Charles Yang (MSFT)

| SMTP mail sends upon boot then the connection is dropped.
|
| We are using MS Exchange smtp server in Exchange 2003 on SBS 2003.
| This is a new installation replacing an older server which is just
| overloaded.
|
| After building the server, installing exchange with service packs etc..
It
| will send mail for a few seconds upon booting then the connection is
dropped
| by the remote server and no more mail is sent. Recieving mail is no
problem
| and works fine.
|
| Using a smal host at the isp. I think that DNS is OK. SMTPDiag tests OK.
I
| have reinstalled IIS and Exchange with no change. This server uses SBS
2003
| hence next step is a complete rebuild so would prefer to avoid this as we
| have some vertical applications install by vendor on the box and would
have
| to pay them to come and reinstall.
|
| The first error is:
| MSExchangeTransport, Connection Manager
| Error 4006, message delivery to the host '123.123.123.123' failed while
| delivering to the remote domain 'post.isp.co.uk' for the following
reason.
| The connection was dropped by the remote hsot.
|
| The old server (which this one is to replace) is configured exactly (!)
the
| same and works just fine.
|
| smtpdiag will deliver to the smart host and is happy that smtp is
configured
| OK.
| Some message get 'out' but something seems to 'time out' or similar.
After
| 10 to 30 seconds the connection is dropped and will not reconnect.
| Using broadband etc...! Browsing is OK.
|
| I have been getting some other error messages that I do not understand as
| follows:
| MSEcxhangeTransport
| Routing Engine/Service
| 967 (also error 969)
| this master server recieved a one level (connector) call back. However no
DS
| chang has been detected and no major increase will occur as a result.
This
| should not result in reset route or updated routing packets being sent
out to
| its subordinate servers and neighboring routing groups.
|
| Since we do not use routing groups I have ignored these to date, but now
| think that there must be some connection.
|
| I have other routing group messages - one says that the connectors
linkstate
| is up (id 973), later followed by one (id 994)saying that the following
| connectors linkstate is suppressed because it points to or comes froma
leaf
| RG node .
| However I have not configured a RG, nor do I wish to.
|
| Comments please....
| regards
| Peter
