Postfix not listening on 25

Hello! I'm setting up a Virtualmin + LAMP stack for the first time and everything works fine except for Postfix. It won't listen on port 25. I can login via imaps and send mail but they don't arrive and I can't receive either.

If I add smtp inet n - y - - smtpd -o smtpd_sasl_auth_enable=yes to master.cf it listens on port 25 but there are still no mails incoming and mails out still won't arrive

This is my main.cf

# See /usr/share/postfix/main.cf.dist for a commented, more complete version


# Debian specific:  Specifying a file name will cause the first
# line of that file to be used as the name.  The Debian default
# is /etc/mailname.
#myorigin = /etc/mailname

smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
biff = no

# appending .domain is the MUA's job.
append_dot_mydomain = no

# Uncomment the next line to generate "delayed mail" warnings
#delay_warning_time = 4h

readme_directory = no

# See http://www.postfix.org/COMPATIBILITY_README.html -- default to 2 on
# fresh installs.
compatibility_level = 2

# TLS parameters
smtpd_tls_cert_file = /etc/postfix/postfix.cert.pem
smtpd_tls_key_file = /etc/postfix/postfix.key.pem
smtpd_use_tls=yes
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache

# See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for
# information on enabling SSL in the smtp client.

smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = mail.localdomain, localhost.localdomain, localhost, h2851315.stratoserver.net
mailbox_command = /usr/bin/procmail-wrapper -o -a $DOMAIN -d $LOGNAME

smtpd_tls_mandatory_protocols = !SSLv2, !SSLv3, !TLSv1, !TLSv1.1
smtp_sasl_auth_enable = yes
mydomain = h2-- edited-out----.net
myhostname = h2-- edited-out----.net
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
home_mailbox = Maildir/
smtpd_recipient_restrictions = permit_mynetworks permit_sasl_authenticated reject_unauth_destination
broken_sasl_auth_clients = yes
inet_interfaces = $myhostname, localhost

And this is my master.cf

25? Thought that was a no go, try 587.

It's not working on 587 either and it's not receiving mails

It's finally working!!

I turned on submission service and I just added 'permit_sasl_authenticated ' to smtpd_recipient_restrictions = permit_mynetworks permit_sasl_authenticated reject_unauth_destination if i remember correctly. I changed the password of two mailboxes and it worked.. what's up with that...?
