try netstat command on either server and see if it has inbound connection
from the other side?
If Exchange->Imail message is being sent (as indicated by the queue
state on the Exchange server), then there has to be something in the SMTP log.
I mean, as soon as the Exchange server establishes connection to the Imail
server it should log HELO servername.
To bypass any DNS issues, you can create an SMTP connector with address
space *imaildomainname.com and point it to the [IP.ADDRESS.OF.IMAIL]
This will force Exchange to give all Imail-bound messages straight to the
IP address of your Imail server without any need to consult with DNS or HOSTS
file.
And if you still don't see anything in Exchange SMTP logs after that,
then Exchange is not even trying to use SMTP to deliver this mail. Somehow the
imaildomainname.com is anchored within Exchange.

Imail
thanks Andrey
I
can telnet from Exch to Imail on:
ip
25
mail.domain.com 25
domain.com 25
I
can telnet from Imail to Exch on:
ip
25
mail.domain.com 25
domain.com 25
No
connections are dropped on either.
As
far as not being a DNS issue, well here is what I can tell you. I do NOT
have split DNS setup. Prior to adding HOSTS file entries
for each "mail.domain.com" and "domain.com" I could not move mail in
any direction at all. Once I set the HOSTS files up all telnet'ing worked,
Imail could send to exchange. Just can't send from exchange to
Imail.
One interesting note is that I tested removing the HOSTS file entries
and creating the internal DNS zones for these domains (split DNS). They were
identical to my external zones except using internal IP's and all records
had their matched PTR's. Afterwards neither server would move mail to the
other. Imail's log showed same errors as always and Exchange indicated could
not resolve DNS name. I am back to using HOSTS files for now till I get it
figured out.
When I turn on logging for smtp on exchange I get no entries at all
for emails being sent TO Imail accounts. All other emailing in and out of
the exchange server writes to logs just fine. If I look at Exchange's Queue
properties for the Imail domain I am trying to send TO I find "trying
remote delivery" and then "the connection was dropped by the remote
host".
When I look at sys.log for Imail server all I see are the entires
of:
[0.0.0.0] connect x.x.x.x (Exch server's IP) port
xxxxx
send error 10054
This error screams connectivity to the mountain tops....yet all
connectivity is fine. Telnet, pinging, tracert......sending mail from Imail
TO Exch....all works fine. Doesn't sound connection based?????? I have
researched goggle, imail and technet and tried/tested all that was
suggested
As
to your suggestions below, I tried everyone one of them and no
glory.
I
know everyone has gotten their fill on this thread. I am about to believe,
given my network, I can have the two severs co-exsist but not route locally
for their domains.
ok what happens if you do Telnet imail.server.ip.address 25 from the
console of the Exchange server?
does Imail drop your telnet connection?
If Imail does not drop the connection just because it does not like
the Exchange server, then it probably drops the connection during data
transmission. It never happened to me, but I have seen other mail servers
(NT Mail for example) drop connections from Exchange because they did not
like 7-bit vs 8-bit encoding.
You can configure the Exchange outgoing message formats to use
different encoding (under Global Settings/Internet Message Formats). You
can create a format just for the Imail domain name.
You can also try to force Exchange to say HELO instead of EHLO. This
is done by configuring an SMTP connector to the address space of your
Imail domain name, pointing the SMTP Connector to the
[IP.ADDRESS.OF.IMAIL] (don't forget the square brackets), and then
changing properties of SMTP Connector to use HELO instead of EHLO.
You can also try to change the properties of Default SMTP Virtual
Server to reduce the number of messages per session or reduce the session
size.

Exchange
default recipient policy (the only one configured in exchange) has
domains totally unique from those in Imail. For
example
Imail =
@houseusers.com
Exchange =
@mycorp.com
They have no
similarities at all.
With Len’s help
the hosts file got mail running from Imail TO exchange but not vice
versa.
Exchange log
says connection dropped by remote server (not verbose) mail just hangs
in queue
Imail log shows
connection errors of 10054
Still trying to
diagnose an error in imail of 10054. Between google/imail KB and
exchange KB I have checked it all…no glory.

I must have missed some original messages in
this thread. What is the domain name in Imail?
What is the domain name in Exchange? - actually
open your Default Recipient Policy and check the SMTP suffixes
there.

Thanks for
the reply Andrey. Actually, I am not using the same domains on both
servers. Each server is hosting unique domains. Both servers reside on
the same physical domain network, but do not share mail domains. I
also got your link to MS support. Thanks and I’ll take a look at
it.

If you have "mydomain.com" on Exchange and
"mydomain.com" on Imail, and try to send mail from [EMAIL PROTECTED]
to [EMAIL PROTECTED],
Exchange will not send it. It will not care about DNS. In Exchange,
Recipient Policies override DNS.

Exchange 2k and Imail
Len, I appreciate your response. John over
on the isaserver.org mail list gives you great credit as a DNS guru.
I have, as John suspected, a split DNS setup. My internal DNS must
be the issue since my external works to perfection. If you could
help I would really appreciate it, since I am limping through this
as I go.
My internal DNS has entries for the host names/
internalf IP's of each of the mail servers. However, no other
entries for those machines. What should my internal DNS look like in
order to resolve my two external mx/A records. This may be too vaque
for you to answer on. If you can let lme know what yo uneed to know
I will provide you with it.
Thanks Lee
(Thanks John for
guiding me)
