Hi,

Just found out that Postfix does not implement/support the AUTH=sender parameter.

So, back to Dovecot, can we use variables in the

submission_relay_user =
submission_relay_password =

then Dovecot will forward the username and password information of the current user to the Postfix submission service for authentication?

Best regards,

Jacky

Hi Gerald and Odhiambo Washington,

Thank you for your suggestions and will try them out.

Best regards,

Jacky

Hi Gerald,

in my postfix/main.cf

smtpd_sasl_authenticated_header = yes
smtpd_sasl_security_options = noanonymous
smtpd_sasl_local_domain = $myhostname
smtpd_sasl_type = dovecot
smtpd_sasl_path = /var/run/dovecot/auth-client
broken_sasl_auth_clients = yes

I am already using dovecot for SASL

The dovecot submission service authenticates users and already added the
AUTH= parameter in the MAIL FROM

MAIL FROM:<jacky@xxx.com> AUTH=jacky@xxx.com SIZE=1430

But, it seems that postfix does not accept the AUTH= parameter and
reject the sender as no logged in.

Hi Jacky,

Your question belongs to postfix mailinng list.

Anyway, the last time I was playing with postfix (I am an Exim user normally), I had to check that:

smtpd_sasl_path = /var/run/dovecot/auth-client  

..the socket is readable by the postfix user:

So, check 10-master.conf for the socket. Something like:

# Postfix smtp-auth

  unix_listener  var/run/dovecot/auth-client  {

    mode = 0666

  }

Restart dovecot and see...
