CVE-2023-51764
Postfix, a popular mail server, was vulnerable.
Postfix allowed SMTP smuggling unless configured with
smtpd_data_restrictions=reject_unauth_pipelining and
smtpd_discard_ehlo_keywords=chunking.
Remote attackers can use a published exploitation technique
to inject e-mail messages with a spoofed MAIL FROM address, allowing bypass
of an SPF protection mechanism.
This occurs because Postfix supports . but some other popular e-mail servers do not.
To prevent attack variants (by always disallowing without ),
a different solution is required, such as using the backported smtpd_forbid_bare_newline=yes option.
