Bei der Anleitung fehlt etwas:

die Zeilen unter

smtps inet n – – – – smtpd

also

-o smtpd_tls_wrappermode=yes
-o smtpd_sasl_auth_enable=yes
-o smtpd_client_restrictions=permit_sasl_authenticated,reject

müssen ebenfalls vom * befreit werden.

Regarding medwinz comment on OpenSuSE. This could also be corrected by adding smtps as a proper service in /etc/services.

The reason for this discrepancy is that formally the smtps does not have an officially recognized port by IANA. Port 465 is (surprisingly) only officially a port for IGMPv3 which is a daemon used in conjunction with multicast services. Since it is very rare to run multicast on the same server as a mail server it is usually safe to allocate 465 for smtps.

@monkey

For openSUSE you need to change the smtps become 465, it will look like

465 inet n – n – – smtpd

I use it and it runs flawlessly

Postfix documentation directs use of ‘postfix reload’ to re-read configuration files including master.cf.

The following is an excerpt from the description of the stop command in the postfix man page.

“Note: in order to refresh the Postfix mail system after a configuration change, do not use the start and stop commands in succession. Use the reload command instead.”
