Testing inbound connection from another intranet machine is not a good idea. 
It's about testing "the way in" whilst beeing inside all the time.

Go testing from an outside host. Some dialup connection or something like 
that.

Can you please copy and paste the lines that show up in the maillog?

No. You have to extend the variable TCPDOPTS by "-noidentlookup".
But it seems not to be your problem.

This is propably not courier, this is something called "Adaptive Soft ESMTP 
server". Search for what machine you connected to.

250-dc also is not courier but it's also not standards conform. Tree digits 
and a space must be the beginning of the (last) answer line.

Also, "domain" is propably not resolvable and therefore no good HELO name.

At least courier (which is not what you have been talking to) requires you to 
follow the ESMTP standard and put your address in angle brackets (<address>).
Also, MAIL FROM should be issued before RCPT TO.


So, you were not talking to courier in your test. And you were not talking 
SMTP in your test.

Please gain back control on your network or ask someone who has it. Then test 
your setup with the procedure that other mail servers would do. (connecting 
from outside, talking correct SMTP, dealing with a correct HELO name, ...)
If it sill does not work, you should have valuable information in your log 
files that you can post here. On the list. Not to my private account.

thanks,
Bernd
