Blank Email Messages

    [ The following text is in the "ISO-8859-1" character set. ]
    [ Your display is set for the "US-ASCII" character set.  ]
    [ Some characters may be displayed incorrectly. ]

I had a similar problem a while back. Not sure if its the same problem
or not. This might sound stupid but what I found out was one of the
optional extra headers that I was using was really long. Not sure which
one it was, this was a few months ago. I simply shortened my custom
header from around 30 or so characters down to 8 and the problem went
away. So if I were you just for sh*ts and giggles, I would look through
all of the headers that you might be adding in and make sure that you
don't have any really long lines. Its just a thought.
