for an IP ?
if you send mail to user@$IP it will work if it's a valid account, you'll need to set up a catch all alias
has anyone got a good understanding of the tls_require_ciphers within exim.conf
I'm failing to start up with tls_require_ciphers invalid: SSL_CTX_set_cipher_list(SECURE128) failed
suggesting it can't use SECURE128
but I don't get why, it is more likley my use of tls_require_ciphers being used wrong, rather than an actual problem
