Hello,
I have a newly installed Cisco IronPort (installed in the DMZ) which is connecting to an Exchange server (installed on the inside network).
I was able to test the outgoing emails.
I need to test the incoming emails. The MX records for this domain are currently pointing to another system. How can I test if the incoming email is functional without having to point the MX records to the system?
Thanks,
Justine.

Hello,
Try to build yourself a SMTP connexion with telnet command. Please find below all steps :
telnet yourcisco 25
HELO existingdomain.com
MAIL FROM: <existingaddress@existingdomain.com>
RCPT TO: <youraddress@yourdomain.com>
DATA
From: existingaddress&existingdomain.com
To: youraddress@yourdomain.com
Subject: EMAIL TEST
CONTENT OF YOUR EMAIL
.
Don't forget to finish your email with a line with only a point "."

Hello Adrien,
Thank you for your reply.
I tried what you suggested, but the IronPort does not recognise any of the commands.
I get the following response:
500 #5.5.1 command not recognized
Maybe there's something missing in my configuration?
Thanks in advance,
Justine.

HELO domain.com
where "domain" is the customer's domain.
I also tried the MAIL FROM but I got the same error.
Thanks,
Justine.

If you are going through the ASA, it is ESMTP inspection what probably kills it. Disable it if you want to test with telnet.
