Suspicious header (OT)

[robin]

I tried to post a reply to list I am subscribed to, Linux Audio Users,  
but a message came back saying my reply had a suspicious header. This 
only happens when doing a reply not a new post. The only info from the 
list admin is "no reason given" Can anyone point out what's wrong,  if 
there is,  so I can remedy the situation.

Header:
