Postfix through 3.8.4 allows SMTP smuggling unless configured with smtpd_data_restrictions=reject_unauth_pipelining and smtpd_discard_ehlo_keywords=chunking (or certain other options that exist in recent versions).

This occurs because Postfix supports <LF>.<CR><LF> but some other popular e-mail servers do not. To prevent attack va
