Resolved SSL smtp not available

[tkalfaoglu]

Hello. I tried the following site for testing.. STARTTLS delivery test · SSL-Tools
it asked me to send an email to them to test the SSL, which I did.. However this did not reach their servers,

Sep 29 09:39:51 ocean postfix/smtp[12387]: connect to ssl-tools.net[168.119.147.146]:25: Connection refused
Sep 29 09:39:51 ocean postfix/smtp[12387]: 2888F11E0F93: to=<check@ssl-tools.net>, relay=none, delay=0.72, delays=0.57/0/0.15/0, dsn=4.4.1, status=deferred (connect to ssl-tools.net[168.119.147.146]:25: Connection refused)

I assume this has to do with connecting to their port 25, not the SMTPS port 465?
How can tell postfix to try both in case the 25 fails like this?

Many thanks, -t

Mail deliveries to remote systems are always done on the SMTP port 25. Every mail system _must_ accept mails on port 25.
TLS encryption is done after the initial handshake: Opportunistic TLS - Wikipedia

The services of ssl-tools.net are currently down it seems, it's not your fault.
