Subject: [PATCH] postfix: 3.8.3 -> 3.8.4

Security: this release adds support to defend against an email spoofing
attack (SMTP smuggling) on recipients at a Postfix server. For
background, see https://www.postfix.org/smtp-smuggling.html.

https://www.postfix.org/announcements/postfix-3.8.4.html

The source URL was modified to another mirror as the current CDN URL
failed to resolve for me from two different hosts.
