Spam Assasin Linux Box

Hi all I hope someone can help

We have a Linux Box that scans mail for Spam and for Virus's etc we have recently moved our Exchange mailboxes to a different domain.

So within Webmin under sendmail Server I changed the domain Routing for that particular domain to point to the new exchange server.

if people now try to email us they get the following

The original message was received at Mon, 24 Mar 2014 16:04:38 GMT
from nm29-vm1.bullet.mail.ir2.yahoo.com [212.82.97.70]

  ----- The following addresses had permanent fatal errors -----
<support@domain.co.uk>
    (reason: 553 5.3.5 system config error)

  ----- Transcript of session follows -----
553 5.3.5 [81.144.150.61] config error: mail loops back to me (MX problem?)
554 5.3.5 Local configuration error

have I missed something  ?

Not sure how you are redirecting, presumably you are using a transport map
@domain.com smtp:newexchangeip:port

The error indicates a loop such that it is possible that either send mail accepts the message, but performs a lookup to determine the next hop which point back to itself.

During this change, you may have overlooked/missed something in the configuration or forgot to reprocess the transport map.

The other option is the exchange server ...

Ok

Al I have done in Domain Routing is change the address in the Send to section to point to the new exchange server.

There is also a relay domains module do I need to change anything there?

Where did you do this?  What interface are you using to administer sendmail on the Linux box?
Presumably on the new exchange your tests of sending email to new exchange got the messages delivered to the intended recipient.

Incoming => sendmail => transport map to new exchange => delivered.

Look at the logs on sendmail to see whether a message you generate is actually delivered to the exchange or sendmail right away detects the looping condition.
