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] (don't forget the square brackets) ((and make sure that this IP is reachable from Exchange)) 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.

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.

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)
