### Security

DMS is now secured against the [recently published spoofing attack "SMTP Smuggling"](https://www.postfix.org/smtp-smuggling.html) that affected Postfix ([#3727](https://github.com/docker-mailserver/docker-mailserver/pull/3727)):

- Postfix upgraded from `3.5.18` to `3.5.23` which provides the [long-term fix with `smtpd_forbid_bare_newline = yes`](https://www.postfix.org/smtp-smuggling.html#long)
- If you are unable to upgrade to this release of DMS, you may follow [these instructions](https://github.com/docker-mailserver/docker-mailserver/issues/3719#issuecomment-1870865118) for applying the [short-term workaround](https://www.postfix.org/smtp-smuggling.html#short).
- This change should not cause compatibility concerns for legitimate mail clients, however if you use software like `netcat` to send mail to DMS (_like our test-suite previously did_) it may now be rejected (_especially with the the short-term workaround `smtpd_data_restrictions = reject_unauth_pipelining`_).
