[Mimedefang] [Patch] multiline fix

[Michiel Brandenburg]

Hi,

I was playing around with the new multiline functions in mimedefang and 
I noticed that there was a earth shattering kaboom, ie .. mimedefang 
would crash.  I make some changes and attached a patch to fix it.

I have tested it with small and way big (more than 30 lines) of response 
and it seems to work.  Feel free to edit it / or fix it another way :)
