Re: Dovecot Submission Proxy Auth

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,

in my postfix/main.cf <http://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 <mailto:jacky@xxx.com>>
AUTH=jacky@xxx.com <mailto: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...
