When sending an email to the extenal company with excel attachment file, it bounces back with the below message :
554-5.7.0 Reject, id=06529-01 - BANNED:554-5.7.0 P=p006,L=1,M=multipart/mixed |554 5.7.0 P=p005,L=1/2,M=application/octet-stream
But in inside the company, we can receive this email. And also when i send the mail with excel attachement to me external mail ( gmail, hotmail ) it works.
If i send an test email without any attachement to this external company; it works.
This means that the external companies is refusing the attachment ? or this issue is in our side.
Is there any way to check in our domino server / spam server, whether the mail is blocked ?
Any ideas how to fix this issue ?
