Postfix returns FQDN instead of domain name in HELO


Hello,

I am managing email for some people with domain arxchange.com. I use Postfix. I only have enough linux knowledge to try to fix issues as they arise. I am totally unable to fix the following proble.

The hosting server has multiple domains hosted on it apart from arxchange.com. The server hostname is web2.manthrasolutions.com.

When I send an mail as raj@arxchange.com to a person at equifax.com, postfix attempts to deliver the message to the equifax user. Equifax's smtp server rejects this with 54
Transaction Failed Spam Message not queued. (in reply to end of DATA command)

I then sent a message to helocheck@cbl.abuseat.org. I noticed that the HELO command returns my server hostname rather than the domain arxchange.com I am sending mail from.

<helocheck@cbl.abuseat.org>: host mail-in.cbl.abuseat.org[82.94.216.251] said:
550 HELO for IP 65.60.32.234 was "web2.manthrasolutions.com" (in reply to
RCPT TO command)

I believe if I can configure postfix to send arxchange.com in response to HELO the problem will be resolved.

I have a rDNS and PTR record setup. It appears to be fine. I checked on the internet.

Any help you can provide is much appreciated.

Thank you very much
