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)
