There is a way to tell exim (well the crypto library actually) to save
the decryption keys so that wireshark can see inside the encryption.
However my normal approach is different.
turn off immediate deliveries by setting 'queue_only=yes' in main
config
Then send a test email, and record its ID (you can find that in exim
main log)
then do
exim -v -M Messag-eIdentifier-Here
and exim will attempt delivery and emit a cleartext transcript of the SMTP session.
