ANNOUNCE: beta 4.27.5 released

Unfortunately the robustness improvements I have made to the MIME decoder
result in it going more slowly. There is pretty much nothing I can do about
this, I'm afraid. The decoder needed to be more robust than it was, as
there have been a couple of cases recently where messages (particularly
caused by MTAs bouncing the whole message rather than just the headers or
the first few lines) have managed to get past MailScanner. You could have
it faster, but at the cost of robustness.
I have just re-written some of the code to try to make it faster, I hope
that will help. If you want to switch off the main improvement, then
disable the "ExplodePart" subroutine in

Sorry, there's not much more I can do about this :-(
