My goodness. That seems extremely odd. The first of those specifies the
size of the buffer Exim uses to read the message off its spool. I can't
believe that can have any effect. The second is the size of buffer it
uses when actually write()-ing the message down the TCP/IP connection. I
guess that could affect the size of packet used. Maybe with large
buffers it is splitting up into multiple packets and the other end isn't
handling these right? As far as I know, nobody else has ever reported a
problem with the default settings.

Suggest you do some experiments!
