How can I disable auth on port 25? I really don't want users to use
port
25 for auth sender. i am using postfix version 3.6.4 on ubuntu 22.04.
its default disabled, no ?
unsure give us "postconf -n | grep auth"
my own is
mx ~ # postconf -nf | grep auth
smtpd_helo_restrictions = permit_sasl_authenticated, permit_mynetworks
smtpd_recipient_restrictions = permit_sasl_authenticated,
permit_mynetworks,
reject_unauth_destination, reject_unknown_recipient_domain,
smtpd_relay_restrictions = permit_sasl_authenticated, permit_mynetworks,
reject_unauth_destination
smtpd_sasl_auth_enable = no
smtpd_sasl_authenticated_header = no
smtpd_sasl_path = private/dovecot-auth
smtpd_sender_restrictions = permit_sasl_authenticated,
permit_mynetworks,
above is in main.cf, in master.cf i have -o smtpd_sasl_auth_enable=yes,
not default no
more questions, show your postconf -n, with you should have done before
asking any questions, if you are unsure try comment lines in main.cf so
it will be default compiled in in postfix, this is maybe bad advice to
somebody, but imho not
note no space around =
