Hi , Very frequently many of the users from our domain are getting below undeliverable error message The e-mail system was unable to deliver the message, but did not report a specific reason. Check the address and try again. If it still fails, contact your system administrator. < mail2.test.com #5.0.0 X-Spam-Firewall; host mail.test.ae[195.229.239.8] said: 552 Error: content rejected (in reply to end of DATA command) Can anyone helpme out with the resoolution .
