Hi,
thank you all guys. The problem was indeed that I didn't properly
enabled tls on connect. I added just a macro on the exim*.localmacros
and I didn't notice that It didn't work. Now I've added
tls_on_connect_ports=465 on the main section and It's working.
Thanks again
cheers
Ale

Incoming connections come from an haproxy on that vps server. I've been able
to route the incoming connections toward port 25. Now I need to enable the
authentication through port 465, but if I enable it on haproxy, my exim
server is not able to interpret the incoming message and I see something
like: "SMTP syntax error in "\026\003\001\001...." on the exim log file.
- The "\026\…." *could* be the proxy v2 proxy header (not sure about the exact
value)
It isn't, it is a TLS client HELLO message. Possibilities:
- The proxy handling has already been done, and the issue
is that the SMTP server is not configured to do "implicit
TLS" on this port (expects STARTTLS).
- The proxy is not actually handling this port and raw
TLS is hitting the SMTP server when it is expecting
the proxy handshake.
My money is on the first variant (it says "SMTP syntax", not
"haproxy syntax" after all).
