why do you not say this clear at the very first beginning

it is usual that you can not and should not
run a public mailserver on a HOME internet

a) most providers are blocking outgoing 25
   sadly not all what would reduce spam massive
   there is practically no reason to use 25 outgoing
   from komeuser-ip's except spambots

b) most other servers will never accept mail from enduser-ranges
   because they are mostly infected spam-bots

c) their support may be unaware of the fact that port 25 is blocked
   because it is usually not for endusers, it is for MTA-to-MX

so you can setup the following options to submit
your messages to whatever account on port 587
see postfix docs for the exact usage of the parameters

this below is a working config to submit system-mails
from one of our external servers to our main-network

relayhost                                           = [relayhost]:587
smtp_sasl_auth_enable                               = yes
smtp_sasl_password_maps                             = 
hash:/etc/postfix/sasl_passwd

if your relay server supports you can even setup ssl

smtp_use_tls                                        = yes
smtp_tls_loglevel                                   = 1
smtp_tls_cert_file                                  = 
/etc/postfix/certs/localhost.pem
smtp_tls_key_file                                   = 
/etc/postfix/certs/localhost.pem
smtp_tls_CAfile                                     = 
/etc/pki/tls/certs/ca-bundle.crt
smtp_tls_security_level                             = may
smtp_tls_note_starttls_offer                        = yes
smtp_tls_session_cache_timeout                      = 3600s
smtp_tls_session_cache_database                     = 
btree:/var/lib/postfix/smtp_scache
