Well, I'm a C programmer and I may be able to help but I'm mainly a 
windows programmer (yes, I know, shame on me :-) ) and I'm not yet all 
too familiar with the Linux programming and especially with the patch 
mechanism and none at all with the diff tool. Nevertheless, I have 
identified the core of the problem (its the call to readheaders in 
drive.c and the response to PS_REFUSED). I still have to check what 
happens if an invalid FROM or TO header is passed after readheaders but 
I think I can fix the program. I'll also need some direction about the 
proper way of doing it for a good integration in the current source.

If you think it is reasonable, we can discuss this further on the 
fetchmail-devel list.
