Hi,
Want to set up a dovecot submission server and which will act as a proxy
in front of a postfix server.
When users deliver email via the dovecot submission proxy, it will
authenticate users and deliver mail to postfix submission service.
The dovecot submission service support AUTH parameter with the MAIL
command (https://tools.ietf.org/html/rfc4954#section-5) and will send
the parameter during the connection of the postfix submission server.
But it seems that postfix ignored the parameter and treats all users as
unauthenticated.
Does anyone know how to configure postfix to accept the AUTH parameter?
Found doc from google search, but it is for exim only
(https://www.exim.org/exim-html-current/doc/html/spec_html/ch-smtp_authentication.html#SECTauthparamail)
Regards,
Jacky
