Indeed.

Well, a way in between would be to take junk at the beginning and
prepend X-Fetchmail-Garbage-Before-Header: and consider the next invalid
header the begin of the body and terminate the header there, put a
message there and then continue - which might however corrupt MIME
multiparts.

Whatever fetchmail is doing at that time, someone will be upset...
