I have a dim recollection that there is some way of setting the
priorities... ah yes! It's right there in the Exim code (the tls-gnu.c
module):
static int default_cipher_priority[16] = {
GNUTLS_CIPHER_ARCFOUR_128,
GNUTLS_CIPHER_AES_128_CBC,
GNUTLS_CIPHER_3DES_CBC,
GNUTLS_CIPHER_ARCFOUR_40,
0 };
I have no idea why the person who submitted the GnuTLS code chose that
particular set of ciphers and that particular order. However, the
tls_require_ciphers option allows you to modify or replace this list.
