I get the following message when my Enterprise Document management System (EDMS) try to send a notification email to a user. I got the error from the EDMS log.

Caused by: org.springframework.mail.MailSendException; nested exceptions (1) are:
Failed message 1: com.sun.mail.smtp.SMTPSendFailedException: 550 5.7.1 Message rejected as spam by Content Filtering.

The EDMS is in another virtual server in the same domain as the Exchange Server. I feel i have to configure the email server to accept email from the EDMS IP.

i need help

Please post Exchange version.
I think Exchange accepts mails from EDMS but it considers them as spam. Is there any antispam working on the Exchange server?
You should include EDMS in the antispam's white list.

The Exchange version is 2010. I have a Small Business Server 2010 which contains the exchange server. I use the POP3 connector to pull email from an external POP3 email host to my exchange server.

I checked the HUB transport feature and found the antispam feature is enabled. But i really dont now how to add the EDMS. The EDMS is also in thesame domain. Will i add the IP the internal or external web address?

You should add the internal IP of the EDMS. This will tell Exchange to exclude from antispam mails coming from that IP.
