Outgoing mail flow problem
I have setup mailman as our school districts list server. For email, we use Google and our domain is ccsuvt.org. The listserv is a subdomain named lists.ccsuvt.org. The problem that we are experiencing is that outgoing email is going to Google that returns a message that there is no user with that name.
At the same time, if I am a member of the list, I can send a posting to the list and all of the recipients receive it if they have an account with Google no matter what the domain (xxxxx@ccsuvt.org or xxxxx@gmail.com.
I must be missing something but I can't figure out why outgoing mail is even going to Google. We are using Postfix so is it a setting in Postfix? Is it a setting in our Google account?
Thanks for any help you could provide.

What is your Mailman setting for SMTPHOST? Is it the default 'localhost' or have you overridden it in mm_cfg.py?

Either SMTPHOST is set to a Google server in mm_cfg.py or it is Postfix. What is the output from 'postconf -n'?

The above tells Postfix to relay all non-local mail via smtp.gmail.com. It appears that Postfix is configured to authenticate to smtp.gmail.com (see below), but it seems that authentication is failing so that server will only accept mail for its local users.
You could remove the above and let Postfix deliver directly to the recipient MX servers, but presumably you don't want to do that.

Here you may want
smtp_sasl_security_options = noanonymous, noplaintext
to prevent plaintext passwords being sent over unencrypted connections.
*smtp_sasl_tls_security_options = noanonymous *
The above smtp_sasl_* settings all look OK. Do you have an entry of the form
[smtp.gmail.com]:587 valid_user:valid_password
in /etc/postfix/sasl_passwd and have you run postmap to update /etc/postfix/sasl_passwd.db?
If so, I don't know what the problem is. Do you see any "SASL authentication failure:" messages in the postfix log (/var/log/maillog?).
Also, see <http://www.postfix.org/SASL_README.html#client_sasl>.
