#Gmail server namr for mac password#

I found this hint very useful and wanted to illustrate its use based on the example of gmail as your outgoing SMTP server. I make no guarantees, but I hope it helps someone. I pieced this information together from lots of useless searches and several useful how-to's and postings. Only the root user should be able to read it.

The chmod go-rx smtp_sasl_passwords removes the group and other/world read/execute permissions on the password files.

When I get it working, I may post an update.

This, I believe, is configured with smtp_tls_CAfile. Other options are NONE, MAY, and MUST, but some will require configuration of the CA so that a trust can be established with the server. This, overall, is not a good idea, but I didn't have time to play with it yet and configure the CA.

The MUST_NOPEERMATCH in the smtp_tls_sites file ignores certificate mismatches when negotiating TLS.

The *_security_options settings allow postfix to use plain text passwords during authentication (albeit over TLS).

You can now check the logs: tail /var/log/mail.logOr, if you're crafty, you'll open a second Terminal window, and before running the tests in the first window, do: tail -f /var/log/mail.logHere are some notes about options that you see in the content above:

If that's the case, try: printf 'Subject: TestnHello' | sendmail -f second test form specifies the 'from' address as you, but can be changed to anything you want as long as it passes muster with your provider's server.
