I am trying to deliver mail to a server on port 465, using implicit SSL.
There is no greeting, I assume the servers are supposed to negotiate the
encryption.
I have tested that the remote server is answering and tests I have done
with
https://testssl.sh/ shows there is a server there and it negotiated.
I read over this page:
https://www.exim.org/exim-html-current/doc/html/spec_html/ch-encrypted_smtp_connections_using_tlsssl.html
It talks about receiving mail and setting up port 465 to receive mail, but
nothing about sending mail that I can see.
What is needed to have EXIM send to a server using encryption other than
STARTTLS?
