Per RFC822, SNF finds the end of the existing headers by looking for
the first blank line. It then injects the headers ahead of that blank
line so that the SNF headers are the last one's present.

Most of the time this works ok. Sometimes if the message isn't coded
quite right there can be something that looks like an extra blank line
in the message. If it's not coded correctly for some reason then SNF
will skip it and move on-- but some software in the chain might
clean-up or interpret the blank line differently -- even the email
client.

The best way to debug this is to put the raw message file through a
hex editor and see how it is encoded. Each line should end with
<CR><LF> and the first blank line should be <CR><LF><CR><LF>. If you
find something else in there then that's likely where the trouble is.

Hope this helps,

Best,

_M
