New submission from Magneto <None>:

This is due to the fact that the empty headers are also emitted. When outlook express sees "Newgroup: \r\n" emitted, even though it is empty, it will treat this msg as a newsgroup reply and will show the icon as newsgroup instead of a normal mailicon.

Attached is the fix to spew_body. (look for [email protected] comment and fix)
