If you run a postfix MTA and find yourself unable to send mails from external eMail Clients like thunderbird, kmail etc.
And you see something like this in the logs:

postfix/smtpd[42360]: Anonymous TLS connection established ...
postfix/smtpd[42360]: NOQUEUE: reject: RCPT from xxx: 554 5.7.1 <[email protected]>: Relay access denied; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<[xxx]>

Then you should consider the newly introduced smtpd_relay_restrictions option as described here:
