assp is man in the middle - both connections are handled independent -
assp tries to use the highest possible encryption mode for each connection

Betreff: [Assp-user] TLS outbound
I have been trying to set up ASSP to use MailJet outbound. I have two
questions in regards:
1) say I have postfix using ASSP as relay host and sends standard emails
on port 25, if ASSP is set up with doTLS and relay hosts with TLS details
is this meant to work end to end or do I really have to have the same
communication type "postfix -> ASSP" as well as "ASSP -> MailJet" ? e,g,
both must plain or TLS but not a mix-and-match right?
2) regardless of the first question, as a test I have set both connection
to be TLS, my emails stay in the postfix queue with the following ASSP log
errors (SSLDebug Levl 3):
