I can receive an email from one particular address but not receive the email if the email has anything in the text or if it has an attachment.

I've checked - whitelists/black lists, changed my password, deleted sent/junk without any success.  

I've spoken with my service provider who as tested and all is OK.

I simply don't understand why I can receive some emails and not others, but I have managed to figure out its seems to be associated with attachements or having anything in the text.

If I send a "test" email with the word "test" in the subject line it comes through OK.  If I add an attachment and something in the text section it will be rejected with the following message

"(email address removed) host mx4.hotmail.com[65.55.37.120] said: 550 SC-001

I hope someone can assist.  Many thanks 

Hi. I’ve moved your post to the Mail Delivery forum.

What’s the e-mail address that was used to send this message to the Hotmail account? Also, do all your senders get this same delivery notice when sending to your account Hotmail address?
