View postfix-upgrade.txt
| 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 <mail@host.com>: Relay access denied; from=<mail@hos.com> to=<mail@host.com> proto=ESMTP helo=<[xxx]> | |
| Then you should consider the newly introduced smtpd_relay_restrictions option as described here: | |
