This could be a packet size problem. Exim sends messages in 8K buffers.
This should not affect the packet size used;[*] however, there was a case
that somebody reported where reducing the size of buffer did have the
effect of reducing the packet size. You can change the buffer size by
setting DELIVER_BUFFER_SIZE in your Local/Makefile.

the application into smaller packets if necessary.
