Maybe they ended up in the spam folder?

Good.

No, I think that's pretty clear: If the server doesn't understand
chunked encoding, then Drakma will try to send the file (and it'll
only do that if you're using a pathname, i.e. the #P"" syntax), but
the server won't accept it - it doesn't know how much it is supposed
to read from the stream.  So, Drakma tries to send data, but on the
other end nobody is reading the data.  That's why the whole thing
appears to be hanging.  You'll probably get a timeout at some point if
you wait long enough.
