Error 504 5.5.2
On /by eGroupIf you send an email and receive the following undeliverable "Delivery Final Failure Notice" with the following information: Reply from x.x.x.x: 504 5.5.2 : Helo command rejected: need fully-qualified hostname Then follow this steps to resolve: 1. Obtain an email address from the sender's domain having issues with sending the message and examine the message headers. 2. Scroll down and examine the "Received: from" line and play close attention to the server name and IP address This is key and more than likely the issue. We need to ensure the server name and IP address matchup with the reverse DNS entry for the sending domain. 3. Perform a reverse DNS Lookup on the IP address you find in the previous step. 4. Ensure the server name in Step 2 matches up with Revese DNS entry from Step 3 5. If these do not match up, then you're on the right track. In my case going to the Trend Micro Interscan Messaging Security Suite (IMSS) Server was the next step. 6. On the IMSS server go to C:Program FilesTrend MicroIMSSconfig and edit the tsmtpd.ini file 7. Once the file is open, hit CTRL-F and search for helodomain, the entry we want to update is in Section 9.3 8. Remove the # sign and add in the reverse DNS entry we found (in Step 3) Entry should look like this: HeloDomain=mail.yourdomain.com 9. Save the file, then go to the services and restart the Trend Micro IMSS SMTP Service, to put the recent changes into effect 10. Next circle back and redo step 1 with a new message, check the message headers and you should see the new helodomain change present 11. Resend the original message and you should no longer be receiving the the 504 5.5.5 HELO COMMAND REJECTED errors Note: If you are not using Trend Micro's IMSS, then your steps will be different for correcting the helodomain. Be sure to check the admin guide for your system and correct as necessary. Tags: 504 5.5.2 HELO COMMAND REJECTED, Exchange, NEED FULLY-QUALIFIED HOSTNAME, OutlookShar

Solved Error 504: Helo command rejected: need fully-qualified hostname Posted on 2007-02-14 Microsoft IIS Web Server Exchange 2 Verified Solutions 4 Comments 8,172 Views Last Modified: 2008-12-06 : Helo command rejected: need fully-qualified hostname> That's the https://www.egroup-us.com/2010/01/how-to-fix-exchange-error-504-552-helo-command-rejected-need-fully-qualified-hostname-4/ error I'm getting when emailing only to certain outside addresses. Otherwise my Exchange setup works fine. I have Exchange 2003 running one one box, M1. I have a gateway Win Server 2003 box running IIS, M2. Both are behind same firewall, part of the same domain. M2 is published in my MX records so all email goes to it. It filters out viruses and passes email to M1. I know outgoing email should be https://www.experts-exchange.com/questions/22389663/Error-504-Helo-command-rejected-need-fully-qualified-hostname.html seeing email sent from M2.domainname.com instead of just M2. I have forward and reverse pointers for M2 in my domain's internal DNS server and I have the followed instructions on this site to no avail: http://msforums.ph/blogs/jpaloma/archive/2006/08/14/Hot-Tip-_2D00_-Need-Fully-Qualified-Domain-Name-_2800_FQDN_2900_-in-HELO-Command-Error.aspx The TCP/IP settings for the computername shows it's fully qualified: M2.domainname.com. What am I missing? 0 Question by:amohat Facebook Twitter LinkedIn Google LVL 104 Best Solution bySembee The problem is the machine that the email is going out to the internet through. Are you bouncing email out through the gateway machine? The FQDN is in IIS SMTP, in almost the same place.

I have checked it, looks fine. M2 is not running Exchange, just SMTP server through IIS, so it does not have that tab of course. So I think the answer is Yes, I have. Anyway, what does M1 have to do with it? All the outgoing ma
