Hello,

the server also supports ssl-smtp on 465 with eases debugging. Since
gnutls-cli --priority NORMAL:%COMPAT -p 465 smtp.jaist.ac.jp
succeeds where
gnutls-cli -p 465 smtp.jaist.ac.jp
fails I think that setting exim's main configuration setting
gnutls_compat_mode (available since 4.70) should help you.
