X-headers The "X-" prefix is used to create custom headers that are legal
under RFC822 but are non-standard and provided for information only.
Conversely, any non-standard informative header should be given a name
starting with "X-".
X-Mailer: (also X-mailer:) A freeform header field intended for the e-mail
software to identify itself. Most Windows e-mail clients identify the e-mail
program, version number, and other information.
User agents include HTML browsers and other types of software that retrieve
and render Web content.

X-Envelope-To header added by sendmail version 8 to specify the actual
recipient when having multiple users in a virtual domain that go to a single
mailbox.
