I think what you are looking for is the "relayhost"
configuration in main.cf.

relayhost = mailrelay.domain.com

and then "postfix reload".

my relayhost with auth in wrappermode is running on port 3000
becase port 25 is used by other smtp (for me only as proxy)

and if I in main.cf setting


relayhost = [mail.host.pl]:3000
smtp_sasl_password_maps = hash:/tmp/auth_smtp
smtp_sasl_auth_enable=yes
smtp_sasl_security_options = noanonymous

in auth_smtp:
mail.host.pl useronrelay:userpassword


when SMTP on relay is in wrappermode maillog on client (my server) always
say connection time out
(I can normal connect to relay server host to smtp from openssl
s_client -connect host:port)
but if I change SMTP on relayhost from warappermode to STARTTLS all is ok

OK Rafal, I understand now.

Postfix can listen in the SSL wrapper mode on port 465. But if
it can send email to another server that's running in the SSL wrapper
mode.... I don't know how to do it. I don't see it documented anywhere
and didn't see anything in Google searches.
